Press Release
Advanced Communications Technologies Demonstrates Revolutionary Wireless Technology -- Worldwide First
Multi-Protocol Functionality on Single High-End Generic Digital Signal Processor
IRVINE, Calif.--(BUSINESS WIRE)--Oct. 11, 2000-- Advanced Communications Technologies Inc. (OTCBB:ADVC - news), today announced that an Australian-based affiliate, which is 20 percent owned by the company, has successfully tested and demonstrated the functionality of its SpectruCell system, a cellular wireless base station capable of processing multiple protocols simultaneously.

The test, conducted at Advanced Communications Technologies Pty Ltd`s development facility in Melbourne, Australia, demonstrates the IS-95 CDMA Physical Layer functionality with a single Digital Signal Processor on the SpectruCell software defined radio (SDR) prototype; seconds before the same platform was broadcasting equivalent GSM signals.

The ability to provide simultaneous multiple protocol (CDMA, GSM) functionality is achieved by reconfiguring proprietary software modules or objects developed by Advanced Communications Technologies Pty in Australia.

``Our engineers in Australia believe that this single processor implementation of IS-95 will revolutionize wireless communications, both from a practical and economic standpoint, and is a worldwide first in the communications industry.

``Equally as important, this functionality was achieved without Qualcomm chipsets or any other dedicated hardware, and marks the successful integration of Radio Frequency, Digital Signal Processing and Signaling Sub-Systems of the SpectruCell multiple protocol wireless base station,`` said Roger May, chief executive officer.

``The completion of the initial SpectruCell prototype is clearly a landmark for our company and the telecommunications industry, and we look forward to commercializing the concept of the SpectruCell multiple protocol wireless cellular base station. We appreciate the sophisticated skills of our engineering team in Australia whose dedicated efforts resulted in the successful development of this cutting-edge wireless technology,`` May added.

May noted that industry analysts have long maintained that simultaneous multiple protocol wireless network functionality within the same network is the ``holy grail`` of the communications industry.

He added that the open architecture and distributed object-based implementation (GSM, CDMA & W-CDMA modules) of SpectruCell, could ultimately challenge the almost ``stranglehold`` position held by major telecommunications manufacturers (Nokia, Ericsson, Motorola, Lucent, etc.) on the wireless communications network industry.

``Management believes the effect of the SpectruCell cellular wireless operating system on the communications industry in the coming years may well be likened to the effect that some of the dominant new computer operating software systems had on the computer industry in the late 1980s,`` said May.

The company has begun to initiate marketing programs to cultivate interest for SpectruCell among the major telecommunications companies in the United States, including Lucent Technologies, Texas Instruments and Analog Devices. Representatives from Advanced Communications Technologies Australia are currently in the United States visiting these companies.

Separately, the company announced it has retained Pondel/Wilkinson Group for investor relations services. The firm`s focus will be on communicating the company`s story to a broad audience, including the investment community, media outlets and the general public in order to establish an identity for Advanced Communications Technologies and enhance shareholder value commensurate with corporate developments.

What Is SpectruCell?

A SpectruCell system is a cellular wireless base station capable of processing multiple protocols (GSM, CDMA, W-CDMA, etc.) simultaneously, all within the same network. The SpectruCell network can process a GSM and a CDMA call simultaneously over a single network structure.

The SpectruCell base station is built on a software defined radio platform, without protocol specific hardware required for handling different protocols. The same SpectruCell network can process all future applications, including the 3G protocols, simultaneously, by upgrading with the appropriate software module. It has also been designed to work with all conventional communications backbones (fiber optic, cable, satellite, microwave, etc.)

This means that communications network operators will be able to use one network to process current and evolving protocols and applications, as well as provide a more cost-effective utilization of their network resources. In addition, the cost of expanding and establishing new wireless networks could be reduced dramatically. Lower network establishment costs generally mean expanded service offerings by the carriers, and lower costs of calls for the consumer.

SDR (Software Defined Radio)

The SpectruCell multiple protocol wireless cellular base station is also believed to be one of the first commercial applications of its kind in the world to utilize an SDR operating platform. The SpectruCell system has also been designed with open architecture and is software upgradeable. It will also be compatible with the latest smart antennae technology.

Independent Industry Validation

ACT is presently collaborating with several parties, including the Telstra (Australia) R&D laboratories, to independently validate the functionality of the SpectruCell system. The SpectruCell design team is now focusing on the production model of SpectruCell commercial network base station.

About the Company

Advanced Communications Technologies Inc., the U.S.-based public company, owns the North, South and Central American rights to SpectruCell, and also owns substantial equity (20 percent) in Advanced Communications Technologies (Australia) Pty Ltd, the developer and owner of SpectruCell, and also the owner of Advanced Network Technologies Pty Ltd, and Australon Enterprises Australia Pty Ltd, a leading-edge LonWorks based Technology Company.

Market Report -- Short Stories (ERICY, NOK, MOT, QCOM)
October 11, 2000 4:22:00 PM ET


QUALCOMM (QCOM) 70 1/2 -9 3/16: Qualcomm was hit late today, with some sources citing news of QCOM-killer technology from Australia. The news was from an Australian subsidiary of an Irvine-based bulletin board company, and boasted of "revolutionary wireless technology." Even if the claims are true, which is far from clear given the source, the news would actually be good for QCOM. The company claims that the technology is a base station which can process multiple wireless protocols such as CDMA and GSM. There is no protocol here that will challenge Qualcomm`s CDMA; there is only equipment which will make it easier for GSM providers to also offer CDMA. If true, this would be good for QCOM. It would only be bad for base station vendors like Motorola (MOT), Ericsson (ERICY), and Nokia (NOK); see press release.

Hier noch eine kurze Zusammenfassung über das Geschäftsmodell und Business Plan der ADVC bzw. deren Einfluß auf die zukünftige Telekommunikationsbranche:

***********************************************************


Drahtlose Kommunikation ist sicher einer der Zukunftsmärkte schlechthin, sehr viel Aufmerksamkeit wird Produkten für den Endverbraucher (z.B. Handys) geschenkt. Die Technologie, die im Hintergrund diese Kommunikation möglich macht, wird wenig beachtet, auch wenn sie ein Milliardenmarkt ist.

Heutige Telekommunikationsnetze, insbesondere Mobilfunknetze stossen an ihre Kapazitätsgrenzen. In den kommenden Jahren wird der Daten- und Sprachverkehr über diese Netze weiter zunehmen, wobei die Kapazitäten nicht beliebig ausgebaut werden können. Bei Mobilfunknetzen besteht darüber hinaus das Problem, dass die Übertragungsprotokolle (in Deutschland z.B. GSM, in den USA CDMA usw.) veraltet sind und nur eine geringe Übertragungskapazität und -geschwindigkeit von Daten und Sprache zulassen.
In Deutschland z.B. gibt es Pläne, in ca. zwei Jahren den UMTS-Standard einzuführen, dazu müsste fast die gesamte GSM-Technologie ausgetauscht werden, dies würde zu Milliardenkosten führen, weil ein derartiges Netz aus Tausenden von Netzstationen besteht die alle auf den neuen Standard umgerüstet werden müssen.
Nach der Umrüstung wäre das Netz wieder nur für den UMTS-Standard ausgelegt, Reisende aus Ländern, in denen andere Protokolle Standard sind, könnten das neue Netz beispielsweise nicht benutzen.

Hier bietet Spectrucell die Lösung:
Spectrucell ist eine Netzwerktechnologie, die alle Übertragungsstandards (GSM,CDMA,AMPS,WAP,3G-Protokolle, z.B.UMTS,etc...) im gleichen Netzwerk unterstützt. Wenn der Netzbetreiber sein Netz mit leicht zu installierenden Spectrucellmodulen ausstattet, wird es sehr viel vielseitiger und effektiver, ausserdem kostet die Umrüstung vom alten Standard auf Spectrucell deutlich weniger als eine Umrüstung auf ein einzelnes, neues Protokoll.
Nachdem das Netz auf Spectrucell umgerüstet worden ist, können beliebig viele neue Übertragungsstandards mit einem einfachen Softwareupdate in das Netz integriert werden, eine kostenintensive Hardwareumrüstung fällt weg.

Spectrucell ist aber nicht nur für Mobilfunknetze geeignet, in Verbindung mit SEM (Spectrally Efficient Microwave) kann ein drahtloses, kostengünstiges Spectrucelltelekommunikationsnetz ein landgestütztes, kostenintensives Glasfasertelekommunikationsnetz ersetzen.
SEM ist eine drahtlose Übertragungstechnologie für Daten und Sprache, die auf Mikrowellenbasis arbeitet. Advanced Communications Technologies befindet sich momentan in Verhandlungen, die Exklusivrechte an dieser Technologie für sich zu sichern.
Ein Telekommunikationsnetz auf Glasfaserbasis ist sehr kostenintensiv, es müssen Leitungen teuer im Boden verlegt werden, Kapazitätserweiterungen sind ebenfalls problematisch.
Wenn das Netz auf drahtloser Übertragung basiert, ist es kostengünstiger aufzubauen und zu unterhalten. SEM ermöglicht auf drahtlosem Weg Übertragungsraten, die mit einem Glasfasernetz vergleichbar sind, in Verbindung mit Spectrucell bekommt der Kunde ein kostengünstiges, drahtloses Telekommunikationsnetz.

Dies bietet z.B. grosse Chancen für Entwicklungsländer, die sich kein teures Glasfasernetz leisten können, aber für ihre Entwicklung eigentlich eine leistungsfähige Telekommunikationsinfrastruktur nötig hätten, der potentielle Markt für diese Technologie ist enorm.
Die Kombination dieser Technologien bietet laut ACT die einzige komplette drahtlose Netzwerk Lösung.
Im Oktober 2000 soll der erste Spectrucell Prototyp zu Freilandversuchen bereit stehen (s. PR von oben) Q2/Q3 2001 soll Spectrucell dann marktreif sein. Unter Umständen wäre es möglich, dass die Konkurrenz ein ähnliches Produkt entwickelt, bisher ist ACT aber noch nichts derartiges bekannt.

Mit einer 70%igen Beteiligung an Australon Pty Ltd hat sich ACT Australia den Zugang zu einer weiteren vielversprechenden Technologie gesichert. Lonworks sind intelligente Kontrollanwendungen, die u.a. über das Internet gesteuert und überwacht werden können, z.B. können Rasensprenger, Licht, Türen oder Fahrstühle gesteuert werden, Computersysteme können überwacht werden, Verteiler- und Verpackungssysteme können gesteuert werden, etc...
"Industry leaders have dubbed Lonworks technology the most significant development in semiconductors since the microprocessor."

Advanced Communications Technologies wird momentan unter dem Kürzel "ADVC" am OTC-Bulletin Board in den USA gehandelt, es ist aber vorgesehen, demnächst an die Nasdaq zu gehen, wenn alle Vorraussetzungen erfüllt sind.
Durch das Nasdaqlisting würde ein sehr viel grösserer
Investorenkreis angesprochen, Analysten können ACT beurteilen, darüberhinaus ist es Investmentfonds
erlaubt, ACT zu kaufen.

Zu beachten ist, dass die in Berlin und München gehandelten Werte mit den Wertpapierkennnummern 907827 und 912334 (Advanced Communications Systems/GRP) nicht das gleiche Unternehmen sind. ADVC kann momentan nur in den USA geordert werden(deutsche Wertpapierkennnummer: 923286, voller Name: Advanced Communications Technologies, Inc.,ehemals MFMI-Media Forum Int.).

Ach ja, hier noch kurz der Link zu unserem thread im OTC:BB board:

Thread: ADVC - Thread III - S/C erfolgreich getestet


Gruß Birger

[oilchange]

Was willst Du uns hier für eine Story verkaufen.
Die angesprochene Technologie, unabhängig davon ob es sie gibt oder nicht, hat überhaupt keinen Einfluß auf den Mobilfunk in Europa. Hier wird UMTS bereits eingeführt, falls dir das entgangen sein sollte. Die Lizenzen sind bereits vergeben und die Ausrüster fangen an bereits die Netze zu bauen.
Wozu braucht man dann noch eine Technologie die, die alten Protokolle über die alten Netzstationen fährt. Das wäre somit nur interessant in Ländern einzuführen, die über beide Netze verfügen also den amerikanischen und den europäischen Standard. Aber selbst die Amerikaner nehmen am neuen globalen UMTS Standard teil. Also diese Technik wird sich, wenn sie denn überhaupt existiert ( solche Geschichten gab es schon viele) nicht durchsetzen. Somit sollte jedes Investment in solche Hersteller vermieden werden. Für mich hört sich das an nach einer neuen Abzockmethode(firma)an, wo nur ein paar Dumme gesucht werden.

[Birger]

Ölwechsel !

Soweit ich das verstanden habe ist - durch entsprechendes Software upgrade - auch eine Nutzung im UMTS-Standard möglich. Allerdings hat das ADVC in Zukunft nur vor. Bisher klappt es nur mit GSM und CDMA.

Allerdings soll eine deutliche Verschnellerung sprich höhere Übertragungsraten auch durch dieses Software upgrade möglich sein. So daß UMTS möglicherweise hinfällig würde.

Ähhh, sicher bin ich mir da aber nicht. Wie gesagt, die Profis seid IHR. Wäre das theoretisch denn möglich?

P.S.: Ich will hier niemanden zum Kauf der Aktien animieren, ich bin eher an kritischen Argumenten pro oder auch contra (Danke oilchange) interessiert...

Was ist SDR ?

Kurz: Was Gutes für 3G ...

Hier ein paar links zusammengefaßt zum Thema SDR und 3G:

http://www.ragingbull.altavista.com/mboard/boards.cgi?board=…



Techs

[Techseeker]

Birger,
das Ziel mit SDR-Basestations ist:

Da wir nicht von heute auf morgen auf UMTS umstellen können und selbst UMTS auch später hinzukommende features
haben wird, bzw UMS nicht gleich UMTS ist, hat SDR folgende Ziele:

- kompatibilität von UMTS zu alten Protocollen (da nicht jedes Land gelichzeitig UMTS einführt und
nicht jeder Carrier eine Lizenz bekam aber dennoch eine Überlebenschance haben muss, denn nicht jeder konsument will direkt UMTS nutzen)
- also hilft SDR der UMstellung von 2G auf 3G
- aber auch jeder Änderung Umstellung danach

Wenn man sich man die SDR links durchsieht (s.o.), dann stellt man fest dass viele sich damit befasse und SDR als die Zukunft
in der Telekommunikation sehen.

Das ist keine Zauberei oder Wundertechnik. SDR ist seit Mitte der 80er in Entwicklung (wurde zuerst bei der Nato eingesetzt)
und kommt gewinnt erst jetzt an Bedeutung für kommerzielle Zwecke, da die Prozessoren inzwischen schneller wurden.

Ich empfehele jeden, sich mal üder

SOFTWARE DEFINED RADIO zu informieren

Auch auf den Webseiten von Siemens, Alcatel, Bosch, Motorola findet man was dazu. Also keine Hype-Wundertechnik ... sondern SDR
wird eine große Bedeutung zukünftig finden.

ADVC ist ein kleiner Startup (ACT Entwicklung Aus 80 Leute + 40 Programmer vom RMIT, mit 14 Mio. gesponort vom start) und der
Vertriebsarm ACT-US hat 8 Leute, noch ...

Also riskant, wie immer, aber es scheint, ADVC hat was multiprotocol SDR angeht den "First-Mover" Vorteil.

Muss man nicht kaufen, aber sollte man sich anschauen, zumindest verstehen was SDR ist.

SDR ist 3G und 3G ist vorerst UMTS

ADVC plant Spectrucell so schnell wie möglich auf 3G zu bringen,

bisher haben die 2G: GSM und CDMA

und fangen gerade an mit erstem 3G-Protokoll: WCDMA

Hier der link zu ACT:

Hier das CNN interview mit dem CEO (13.10, Part1 und Part2 anklicken)
http://cnnfn.cnn.com/services/fnonair/video/dj/

In dem CNN interview hat RM nochmal darauf hingewiesen, dass 3G Protokolle (also UMTS) das Ziel sind. Da SDR aber "alles" kann, haben die mit den alten
Protokollen angefangen, fangen demnächst aber mit WCMA an, was ein 3G Protokoll ist. Somit kann die Umstellung gelingen und gleichzeitig
ist das Netzwerk futureproof, egal was sich an UMTS noch ändert oder was dazukommt. Bisher, ist UMTS Europa, UMTS USA und UMTS Asien ebenfalls nicht
kompatibel und wird es auch nicht werden wie es aussieht .... also ...

Also, bitte schaut euch an was SDR ist, insbesondere da UMTS nocht gleich UMTS und INSBESONDERE da UMTS nicht statisch bleiben wird, jede Erweiterung, Änderung, Zusatzprotokolle, Äbderungen bedürfen normalerweise
einer Hardwareänderung. MIT SDR nicht, dann sind das nur noch Softwareupgrades, deswegen gilt SDR als DER weg UMTS zu realisieren.

Danke Techseeker.

Sieht so aus, als hätte ich mal wieder nur die Hälfte verstanden von der story von ADVC bzw. dann habe ich Roger May in einem der letzten Conference Calls schon richtig verstanden, mich von <oilchange> aber gleich verunsichern lassen.

Birger,

Also SDR-multiprotocol heißt:

- keine neuen Netzwerke bauen, sonder Alte nachrüsten, evtl. erweitern, aber kein komplett neues machen
- cool für Umstellungsphase 2G zu 3G
- und futureproof für 3G, weill sich da ständig was ändern wird oder hinzukommt, man das aber als Software upgrade einfach draufläd
- und es jetzt schon verschiedene 3G Protokolle gibt, also weltweit macht multipotocol Sinn
- SDR kann so schnell sein, so daß Nicht-UMTS Lizenznehmer tortzdem den gleichen schnickschnak machen könnten

SDR ist legitim und erprobt und viele arbeiten mit Volldampf drann, das ist keine "Wundertechnologie", sonder das Ding in der zukünftigen Telco-branche.


selbst wenn, auch UMTS ist nicht gleich UMTS, es gibt jetzt schon 5 verschiedene UMTS Varianten, die schwierig oder nicht kompatibel sind.

Außerdem wird sich UMTS auch ständig verändern und wird erweitert. Die Zukunft liegt in SDR, das
kann man überall lesen und S/C ist eine SDR basestation. Das wir mit alten Protokollen anfangen hat den Vorteil: UMTS
version noch nicht klar, und
bis das eingeführt wird dauert noch, Also gibt es eine Umstellungspahse von 2-3 Jahren. Und wenn dann klar ist,
welches UMTS dann kann man es ja nachladen.

Also wenn einer sagt, wenn UMTS kommt haben wir weltweit ein Protokoll und brauchen multiprotokoll nicht mehr, oder
mach braucht keine
Kompatilibilität nach unten nicht , weil wir ja weltweit alles gleichzeitig umbauen und sich alle direkt neue Handys kaufen ....
dann denke ich mal steckt er
nicht so im Thema drin.

SO, tut mir leid dass ich so ein SDR-Fan bin, alles posts von mir nur meine Meinung und ich habe eh keine Ahnung.

Also ADVC muss man nicht kaufen wenn einem zu risky als startup unternehmen das gerade Erfolg, es gibt noch andere die sich damit beschäftige. ADVC war
wohl nur der erste. SDR ist es aber wert sich damit zu beschäftigen und zu gucken, wer ds noch so macht.

Tschö, Techs

von H1S2 :

Sag ich´s doch, mit SpectruCell wär das nicht passiert

UMTS - Doppelt Teuer

Zu den etwa 160 Mrd. Euro, die die TK-Unternehmen insgesamt in Europa für die UMTS-Lizenzen bezahlen müssen,
kommen Investitionen in etwa gleicher Höhe hinzu. Allein in den Jahren 2002 bis 2005 werden jährlich etwa 20 Mrd. Euro für
den Aufbau der erforderlichen Infrastruktur aufgewendet werden müssen.

Das führt dazu, dass sich die Kreditaufnahme der Branche in Europa gegenüber dem Vorjahr verfünffacht hat und 1999 auf
mehr als 100 Mrd. Euro angewachsen ist. Im laufenden Jahr sollen etwa 90 Mrd. Euro hinzukommen, die vornehmlich zur
Finanzierung von Lizenzkosten benötigt werden.

Gegenwärtig umwerben die Anbieter für die UMTS-Infrastruktur die TK-Gesellschaften heftig. Jetzt geht für die Ericssons,
Lucents, Nokias, Nortels und Siemens dieser Welt darum, sich eine möglichst große Scheibe vom Kuchen abzuschneiden.
Dabei ist man zu teilweise ungewöhnlichen Zugeständnissen bereit. ..weiter

Vendor Financing wird eher die Regel als die Ausnahme. So ist z.B. bei Nokia der Anteil solcher Geschäfte im Januar 2000
auf über 10 Prozent gestiegen. Im Januar 1999 hatte der Wert noch bei knapp 7 Prozent gelegen.

Seitens der Betreiber von Mobilfunknetzen rückt die kürzestmögliche Lieferzeit als Auswahlkriterium für den Lieferanten in den
Vordergrund. Erst in zweiter Linie geht es um technische Eigenschaften. Dabei ist besonders wichtig, dass die Systeme
offen für neue Dienste sind. Welche das sein könnten, davon hat man heute teilweise noch gar keine konkrete Vorstellung.


Die langfristige Bindung an den Infrastruktur-Lieferanten versuchen deren Kunden dadurch abzumildern, dass sie die
Herausbildung von Standards und Standardschnittstellen innerhalb des Infrastruktursystems vorantreiben.

Bis zu einem gewissen Grade wird das auch von den Anbietern unterstützt, kann man damit doch den kundenspezifischen
Engineering-Anteil reduzieren. Das ist auch angesichts des katastrophalen Mangels an IT-Spezialisten geboten.

INTO THE BASESTATION OR HANDSET ? ... some links

(... there are quite some articles on that issue, have a look for yourself, here are some for a start)

"It is reasonable to forecast that the first soft-radio implementation will occur in the basestation arena, where power consumption in such extremee high-performance
data converters is less of an issue, while handset or other mobile implementations will lag well behind."
http://www.planetanalog.com/story/OEG20000204S0006

are capable of executing the separate standards evolving in the United States, Europe and Japan."
http://www.semibiznews.com/archive/19990521a4.html

"The IP provider has identified the wireless base station as its initial target application because, according to Ralston, that`s where software-reconfigurable radio
technologies will first be proven. "We address the needs of the wireless industry value chain from top to bottom," he adds, "but we start with network operators and
service providers to help define the nature of the problems imposed by today`s multiplicity of standards, as well as the emerging need to support multiple data rates."
http://www.s2mag.com/Editorial/1999/dsp9906.html

"This is especially relevant for wireless basestations, where it offers significant benefits: reducing the cost, size, complexity, and power consumption of a basestation
(perhaps as much as fivefold). More importantly, it can support a variety of air/modulation schemes and protocols (AMPS, NAMPS, TDMA, CDPD, etc.) simultaneously,
and switching between them whenever required."

Excert from the "SDR-Forum Response to the FCC Notice of Inquiry on SDR"

"[...] When multi-band SDR technology is broadly deployed in base stations, infrastructure, and subscriber equipment, it will enable various means of
improving spectrum sharing. SDR user terminals with sufficient computational resources could indeed monitor blocks of spectrum and locate free spectrum. But we
anticipate that the owners and operators of wireless networks would prefer to have the base stations and infrastructure select the spectrum and protocol,
rather than allowing subscriber equipment to perform this role. This is because infrastructure equipment will always be more capable than user terminals
of handling the technical issues of locating unused spectrum; prioritizing access, terms, and conditions; negotiating for access; and checking for hidden
transmitters. In addition, leaving spectrum and protocol selection to network operators will also minimize the power and complexity requirements of
portable and mobile equipment.

Second, SDR will enable another class of signal-processing functions that holds great promise for increasing the number of users that a wireless cell can support: this
class includes smart antennas, multi-user detection (MUD), and interference cancellation. This group of signal-processing improvements will enable base stations to
hone in more specifically on each user`s location, permitting beam-forming transmissions that have already been shown to increase the number of users that a cell can
support by at least 300-400%. These signal-processing technologies have already been thoroughly tested and are nearly market ready. The SDR Forum is working on
standardizing this class of functions so that all user terminals and all base stations will be able to communicate with one another [...]"

In dieser PR von gestern steht es schwarz auf weiß, daß in Zukunft auch UMTS mittels Software Defined Radio (Spectrucell) möglich sein kann. Bei entsprechendem Software upgrade.






Advanced Communications Technologies Expects SpectruCell
Technology to Benefit From Presidential Directive

IRVINE, Calif.--(BUSINESS WIRE)--Oct. 17, 2000--

Company`s Multi-Protocol Wireless Base Station Complements
Future 3-G Applications

Advanced Communications Technologies Inc., (OTCBB:ADVC), today announced
enthusiastic support for President Clinton`s recent directive for the
Federal Communications Commission to secure airwaves to be utilized for
next generation 3G wireless services.

Advanced Communications Technologies announced last week that its
Australian-based affiliate, which is 20 percent owned by the company, had
successfully tested and demonstrated the functionality of its SpectruCell
system, a cellular wireless base station capable of processing multiple
protocols simultaneously.

The functionality was achieved without Qualcomm Chipsets, or any other
dedicated hardware, and marks the successful integration of RF, DSP and
Signaling Sub-Systems of the SpectruCell multiple protocol wireless base
station -- representing a worldwide first.

Roger May, chief executive officer, who appeared on CNNfn`s "Digital Jam"
on Friday, Oct. 13, 2000, said he expects SpectruCell to be available
commercially by the beginning of the third quarter of 2001.

May noted that SpectruCell allows network providers to seamlessly migrate
their current 2G network infrastructures, including CDMA, GSM, PCS and
TDMA to a 3G system, such as W-CDMA, UMTS and Mobile IP. The company`s
SpectruCell technology is uniquely designed as network tool to take full
advantage of the impending evolution to 3G applications.

"As the FCC works with the private sector to better utilize the capacity
of airwaves in the United States, SpectruCell offers a unique ability to
dynamically reconfigure and implement new and evolving protocols - in both
domestic and international markets.

"Because of the software upgradability and open platform design of
SpectruCell, a network provider can effectively update its network to
support a large range of 3G based protocols without major hardware
deployments. Network operators will be able to use one network to process
current and evolving protocols and applications, while also providing a
more cost-effective utilization of their existing network. In addition,
the cost of expanding and establishing new wireless networks could be
reduced dramatically and lead to lower costs for the consumers," said May.

May noted that the company`s Australian-based affiliate, Advanced
Communications Technologies Pty Ltd., is currently planning aggressive
measures to bring SpectruCell to market earlier than originally planned by
increasing R&D resources and staff by up to three times current levels.

What is SpectruCell?

A SpectruCell system is a cellular wireless base station capable of
processing multiple protocols (GSM, CDMA, TDMA etc.) simultaneously, all
within the same network. The SpectruCell network can process a GSM and a
CDMA call simultaneously over a single network structure. The SpectruCell
base station is a software-defined radio (SDR), where software modules
handle the processing of air interface protocols without the need to have
protocol specific hardware. The same SpectruCell infrastructure equipment
can process all future air interface protocols, including the proposed 3G
protocols. Changes to the behavior or the ability to support multiple air
interfaces simultaneously, is accomplished by loading the appropriate
software modules. It has also been designed to work with all conventional
communications backbones (fiber optic, cable, satellite, microwave, etc.).
This means that communications network operators will be able to use one
network to process current and evolving protocols and applications, as
well as provide a more cost effective utilization of their network
resources. In addition, the cost of expanding and establishing new
wireless networks could be reduced dramatically. Lower network
establishment costs generally mean expanded service offerings by the
carriers, and lower costs of calls for the consumer.

SDR (Software Defined Radio)

The SpectruCell multiple protocol wireless cellular base station is also
believed to be one of the first commercial applications of its kind in the
world to utilize an SDR operating platform for infrastructure equipment.
The SpectruCell system has also been designed with open architecture and
is software upgradeable. It will also support the emerging smart antennae
technology.

Independent Industry Validation

ACT is presently collaborating with several parties, including the Telstra
(Australia) R&D laboratories, to independently validate the functionality
of the SpectruCell system. The SpectruCell design team is now focusing on
the production model of SpectruCell commercial network base station.

Puzzle of software-defined radio has multiple solutions
Patrick Mannion

The road to one of the communications industry`s most elusive goals, the
software-defined radio, will probably not be a straight line. As the advent of
second- and third-generation cellular networks turns up the heat in the quest for
this crucial piece of technology for wireless handsets and basestations, chip
makers are juggling a multitude of possibilities. Indeed, some say a
mix-and-match approach seems more likely than a single, clear-cut solution.

If the answer is far from a slam-dunk, the need is not. "The [3G] deployment is
going a lot faster than people expected," said Randall Fahey, vice president of
marketing at startup Morphics Technology Inc. (Campbell, Calif.). "We`re
seeing the new networks taking off. It`s going to happen next year."

Service providers don`t want to install new basestations for each new air
interface or wireless data scheme coming down the pike. And consumers won`t
buy multiple phones and PDAs to cover each wireless service they use, and
each city or country to which they travel.

Software-defined radios let service providers reprogram basestations to reassign
channels as standards change and the mix of analog vs. digital users shifts. And
engineers envision handsets that someday will download from any network
whatever code is needed to reprogram themselves to access a wireless service
or run a mobile application.

Seven solutions

There`s no shortage of silicon approaches to the problem. Mark Cummings,
chief executive officer of enVia Inc. (San Jose, Calif.), has whittled them down
to seven. From most to least conventional they include high-speed DSPs,
multiple ASICs, parameterized hardware, switchable microcode, multiprocessor
arrays (such as very long instruction word architectures), reconfigurable logic
and a combination of any of the above, said Cummings, who was instrumental in
the formation of the SDR Forum.

"I think it`s a little misguided to think about it as an ASIC vs. FPGA vs. DSP,"
said Jeff Bier, general manager of Berkeley Design Technology Inc., a
Berkeley, Calif.-based DSP consulting and software development firm. "I would
rather think the solutions that will be successful will combine elements of some
of those."

Bier said he expects to see solutions that might incorporate a programmable
processor alongside hardwired circuits and reconfigurable logic of some sort.
"The most successful designs will be pulling together pieces," he said.

To date, the development of software-defined radio has been confined to
military applications, such as snooping or jamming communications, where cost
and device size are not significant constraints.

But semiconductor advances combined with the imminent arrival of 3G wireless
systems are driving software-defined radio toward commercial markets.

"I think the fundamental thing that`s going to make software-defined radio
happen is the current move to 0.13-micron technology," said Jim Gunn, an
analyst with Forward Concepts (Austin, Texas).

Key hurdle

The key hurdle is providing the processing punch to convert analog RF
functionality into the digital-and eventually the software-domain. The earlier in
the chain the data is converted, the more processing power is required.
Engineers see two approaches to that problem.

"The first way is to have a completely flexible RF front end that can handle any
standard and give you the baseband no matter what format," said Srikathyayani
Srikanteswara, a senior graduate research assistant at the Mobile and Portable
Radio Research Group at Virginia Tech (Blacksburg, Va.). "The other is to
sample the incoming waveform right at the antenna. Right now we can`t do
either.

"Theoretically, you could come up with an analog-to-digital converter that could
sample up there, but it would be extremely expensive and bulky and unusable,"
she added. "The other problem is that even at baseband, the wide variety of
standards, with different baseband processing, makes it a signal-processing
nightmare in terms of flexibility, speed, power, cost, footprint and available
processing horsepower."

Until recently, the choice of approach was dictated by the type of system.
Basestations, generally more tolerant of power and heat, might tap banks of
DSPs, while handsets would employ ASICs for gains in speed and size, with
lower power. But now the lines are blurring.

"Thanks to microcells and picocells, at least a portion of the basestation market
is moving toward what are known as `shoebox` designs, meaning that now
basestations are facing many of the same issues as handsets in terms of form
factor, power consumption and cost," said Cummings of enVia.

Not surprisingly, chip makers tend to advocate approaches most in line with
their product portfolios. Brad Taylor, director of applications at startup
Chameleon Systems Inc. (San Jose), said reconfigurable CPUs like his
company`s CS2112, announced earlier this year, will outperform DSPs and
FPGAs in soft radios.

Taylor admitted that the CS2112 may run a little more slowly than a DSP, a
function of the fact that reconfigurable hardware techniques often entail more
interconnect delay. "We tend to see a significant performance advantage,
though, since we have more multipliers and we can keep them all busy," he said.

For a good fit with the classic software-defined radio application, the processing
fabric must be able to switch functionality in real-time. "This is a shortcoming of
FPGAs," said Taylor. "You can`t change them in real-time, as it takes a half
second to change the functionality, and the whole system goes down."

With the reconfigurable Chameleon chip, "we can load the new configuration
while running the old one," he said. "We swap it over, and we jump right into the
new protocol."

But cost is still an issue. "Our goal," Taylor said, "is to get flexibility and
performance at least in the range of ASIC costs." Pricing isn`t available yet on
the 0.25-micron device.

Another startup eying software-defined radio is Morphics. Unlike Chameleon,
which targets basestations only, Morphics is targeting both basestations and
handsets-the former with chip sets, the latter with licensable cores. Founded in
1998 and still in stealth mode, the company plans to announce product in the first
quarter of 2001. Morphics will be competing for the handset market with
companies like Quicksilver Technologies and Sirius, a Belgian firm.

The complexity of wideband-CDMA networks will drive the need for
software-defined radio, said Morphics` Fahey.

Wideband CDMA

"With GSM, gate counts jumped to 30,000 to 50,000 gates for the convolutional
coding and Viterbi coding," Fahey said. "And with IS95 CDMA, that ASIC is
now 100,000 gates. The problem is when you go to wideband CDMA, now that
ASIC functionality will be the bulk of the signal processing-in the order of
700,000 to a million gates."

DSP vendors are tackling the performance problem "with different approaches
to the cores, VLIW, superscalar, multiprocessing-essentially homogenous
multiprocessing," he said. "[They are] throwing more MACs
[multiply-accumulate operations] at the problem, but it`s tough to keep the
MACs fed and you need to add huge caches to do that. So you start to run out
of efficiency anyway."

Fahey said Chameleon`s approach has efficiency advantages over regular
FPGAs, but will not make inroads into handsets. And that is where Morphics
sees its advantage.

The company takes a heterogeneous-multiprocessing approach. "Instead of
having a bunch of MACs all running in parallel, we have some very specialized
processors that have been optimized with advanced knowledge of the algorithms
we`re running on them," Fahey said. "We`re not mapping [the functionality] onto
a MAC but onto specialized processors, or specialized processing kernels."

Morphics` approach raises the question of just where the soft-radio work should
be handled-handset or basestation?

"Having this in the basestation is a very inefficient use of spectrum," said
enVia`s Cummings. "You have to allocate blocks of channels to a new user
entering the cell site-you can`t allocate just a single voice channel. It may also
need a guardband, depending on how sensitive the channel is to what`s
happening in adjacent spaces. What happens is spectrum fragmentation."

Pointing to the scarcity of spectrum, Cummings said this is not the way to go.
"We`d rather have the basestation be a particular air interface and have the
handsets conform to that air interface. At the same time, we`d like to be able to
change the air interface in the basestations"-hence the soft-radio
requirement-"but at a much slower pace, in a more managed fashion as
technology and the business evolve," he said.

Such an approach favors products such as Xilinx Inc.`s Virtex-II FPGA, which
will incorporate a 300-MHz, 32-bit processor capable of 350 Dhrystone Mips.
The device, which is set to go into production in 2001, tackles many problems,
such as configuration (software-defined radio download) and network issues,
which are best suited to a RISC processor.

"With the inclusion of a RISC tightly coupled to a high-performance FPGA
fabric, software-defined radio designers will be able to realize all aspects of an
SDR system-from demanding DSP functions to more control- and
decision-intensive operations that are best handled by a processor," said Chris
Dick, DSP group manager at Xilinx (San Jose). Xilinx`s goal is to let OEMs
design systems with the flexibility of an all-software solution and the
performance of an ASIC approach, he said.

Whatever approach OEMs adopt, the move to soft radio could come soon, given
that 3G cellular nets are almost ready to roll. Japan is on the cusp of activating
its wideband-CDMA network, and Europe has seen a noticeable uptick in 3G
activity. "Companies paid a high premium for spectrum licenses during the last
round of auctions," said Bengt Callmer, director of communications at Ericsson
Microelectronics (Kista, Sweden), "so they`re now in a real push to start getting
a return on these investments."

Advanced Communication Technologies Announces
Commercial Test of SpectruCell Base Station with
Platforms Wireless International Corporation

IRVINE, Calif.--(BUSINESS WIRE)--Nov. 28, 2000--

-- Commercial Testing for Brazilian market in March 2001 --

Advanced Communications Technologies Inc., (OTCBB:ADVC), today announced that it
has entered into a Strategic Alliance Agreement with Platforms Wireless International
Corporation (OTC:PLFM) to deploy an airborne version of the SpectruCell software defined
radio wireless base station for commercial testing in a pilot network test in Brazil in early
2001.

Platforms Wireless International Corporation ("Platform") has contracted with Advanced
Communications Technologies Inc. ("ADVC"), on an exclusive basis, to provide a
SpectruCell airborne wireless base station for an aerostat based communications
platform.

The success of this collaboration will enable both companies to significantly expand the
global market potential for their products through airborne wireless communications
networks that are not limited by specific wireless system protocols.

"The airborne communications solution is an effective way of implementing a wireless
network without having to incur the high costs and deployment delays associated with the
establishment of land based networks. We expect this undertaking will produce one of the
most advanced and cost-effective wireless communications system prototypes available
on the market," stated Roger May, CEO of ADVC.

The SpectruCell system deployed in Brazil will initially provide functionality for the TDMA
communications protocol, however, the software defined radio platform of SpectruCell will
enable the Airborne Relay Communications "ARC" System to process multiple protocols
by simply adding protocol specific software modules.

SpectruCell`s multiple protocol functionality allows for the provision of advanced wireless
communication services without specific protocol limitations, facilitating the penetration
and expansion of rural, emerging-nation, and under-served global markets without existing
land based infrastructure.

Earlier this year, Platforms entered into a conditional contract with Americel S.A., one of
the leading cellular telecommunications providers in Brazil, to use the Platforms`
revolutionary ARC System as an airborne telecommunications switching platform, aboard
an aerostat infrastructure. The contract calls for up to five ARC Systems valued at
approximately $65 million each (total $325 million), with commercial testing of the System
scheduled to begin in March 2001.
