Advanced Communications Technologies Inc. -- 3G Shared/Virtual Networks Utilizing SpectruCell SDR Base Stations
MONDAY, JULY 30, 2001 9:55 AM
- BusinessWire

LOS ANGELES, Jul 30, 2001 (BUSINESS WIRE) -- Advanced Communications Technologies Inc. (OTCBB:ADVC) (ACT-US) today confirmed that the company`s Australian affiliate Advanced Communications Technologies (Australia) Pty Ltd is currently negotiating with several major U.K. and European carriers to provide SpectruCell based Virtual or Shared Networking infrastructure for the rollout of third generation (3G) networks.

ACT`s software defined radio (SDR) SpectruCell technology is ideally suited to provide common infrastructure for multiple network operators. In planned 3G network rollouts, carriers can both minimize network establishment costs as well as remove technical and compatibility issues that up until now have prevented network operators from sharing a single mobile wireless network infrastructure.

ACT`s SpectruCell SDR based Virtual/Shared networking will be able to provide major cost savings and crucial competitive advantages for network operators as telecommunications regulators globally seek to implement sharing of network infrastructure as a means to speed up and ensure the roll out of 3G mobile services.

SpectruCell lowers infrastructure costs for network operators by allowing them to share common equipment and backhaul services and provides next generation management and accounting facilities to ensure quality of service between carriers. These features significantly lowers the total cost of ownership for a network provider.

This key ability is derived from SpectruCell`s SDR operating system (patent pending), which allows network operators to simultaneously support multiple communications standards (GSM, CDMA, W-CDMA, 3G etc) on the one network infrastructure. Importantly, this support can be achieved using the same or different bands of radio spectrum over the one SpectruCell based infrastructure. Unlike present hardware based 3G solutions, any additional protocol support requires relatively minor software upgrades to the SpectruCell SDR Base Station.

"The planned rollout of 3G networks is placing an incredible financial burden on network operators around the globe," said Roger May, Chairman of ACT-US. "As a consequence, concerned industry regulators are increasingly turning to infrastructure sharing to reduce the cost and ensure the rollout of 3G services. ACT`s SpectruCell SDR base station is the only known technology that will be available in early 2002 that has the ability to provide secure seamless simultaneous support for multiple communications standards for several competing carriers on the one network infrastructure."

This unique proprietary capability of the SpectruCell base station is particularly suited to the massive U.S. market where regulators are encountering many 3G rollout difficulties and also in the European market where network operators have outlaid tens of billions of dollars for 3G spectrum.

One major European mobile carrier plans to implement some 40,000 base stations in their 3G rollout, compared with the 10,000 in their current 2G network. This global requirement to increase the number of cell sites in order to roll out 3G services is requiring both regulators and operators to move to a shared network model for 3G network rollouts. The company believes that SpectruCell is the only technology, expected to be available in early 2002, that can support planned 3G shared network infrastructure and that has the ability to comply with proposed FCC standards.

"The pressure on the U.S. market to secure 3G spectrum is immense with everything from Presidential directives to specialist FCC reports being issued to combat the problem. SpectruCell`s ability to be dynamically reconfigured in real time provides the ideal solution in that it could simultaneously support 3G services in existing spectrum that is presently used for a 2G service like CDMA or GSM," said May.

Recent statements from both the U.S. Department of Commerce`s National Telecommunications and Information Association, NTIA and the U.K. regulator for the telecommunications industry, OFTEL, have confirmed that infrastructure sharing will be increasingly championed as the solution to expensive 3G network rollouts. This powerful industry pressure and high cost of existing hardware based solutions is providing ACT with an exceptional opportunity to generate substantial revenues from the increasing global demand for next generation 3G network upgrades.

ACT is also currently negotiating with one major U.S. carrier to implement SpectruCell SDR base stations in their current mobile network and their planned provision of third generation services.

ACT`s SpectruCell technology is supported by several patent applications and the recent securing of development alliance with RLM Systems, a joint venture between Lockheed Martin (NYSE:LMT) and Tenix Australia.

Advanced Communications Technologies -- New Patent Filing Holds Key to SDR Implementation of CDMA and 3G Applications
MONDAY, JULY 16, 2001 7:21 AM - BusinessWireLOS ANGELES, Jul 16, 2001 (BUSINESS WIRE) -- Advanced Communications Technologies Inc. (OTCBB:ADVC) (ACT-US), today announced that its Australian-based affiliate, Advanced Communications Technologies (Australia) Pty Ltd (ACT-Australia), has filed a key patent application relating to the company`s 3G ready SpectruCell multiple protocol base station technology. The new patent filing directly addresses the implementation of CDMA (IS-95) on a software defined radio (SDR) platform. ACT-US holds the exclusive rights for SpectruCell in North, South and Central America.In addition to several other key elements, this latest patent filing documents a method developed by ACT-Australia engineers for the software implementation of a Finite Impulse Response (FIR) filter utilized by the CDMA (IS-95) system on the company`s software defined mobile wireless base station technology -- SpectruCell.Whilst existing CDMA based technologies, like those patented by QUALCOMM (Nasdaq:QCOM), implement these filters in hardware, SpectruCell`s design calls for an implementation in software radio via use of a digital signal processor (DSP). In order to reduce the processing resources required of the DSP, the filter has to be implemented as efficiently as possible.The granting of this patent application, relating to ACT`s new method of implementing IS-95 FIR (CDMA) on software defined radio, may remove the necessity to use chipsets from vendors like Qualcomm to perform the FIR function as it is done in conventional hardware based solutions.This implementation of IS-95 FIR on software radio has been uniquely achieved by the ACT-Australia engineers. This was achieved by developing a process that results in a very efficient FIR 24-tap filter that replaces two filters, namely the baseband and phase equalisation filters, on the forward CDMA (IS-95) link. Perhaps most importantly, in addition to being extremely efficient the filter also satisfies all CDMA (IS-95) specifications for transmission filtering. Existing technologies, which can require as many as 70 taps (a process executed in software) normally consume too great a portion of the DSP`s processing power to enable an appropriate solution capable of meeting the CDMA standard`s specifications."ACT`s development of this technological application has the potential to provide a significant roadblock for any competitor seeking to implement CDMA on an SDR platform," said Roger May, Chairman of ACT-US. "This and the other leading edge developments initiated by our engineering team only serve to further demonstrate the company`s global leadership in software defined radio development and implementation for wireless communications infra-structure. With the SpectruCell technology now receiving much more recognition from both network operators and industry regulators in the USA and Europe, ACT`s solid technological lead in SDR technology development and implementation should provide investors with an exciting new opportunity to capitalise on the potential of the rapidly expanding demand for SDR solutions in the global communications network infra-structure marketplace.""The company has made enormous progress in all facets of the development of the SpectruCell SDR multiple protocol wireless base station since the successful testing of the prototype in October 2000. In addition, several other key communications platform based products (Third party 3G software development kit, core SDR processor engine, front end analog receiver card, and a digital up/down converter and switching card) with broad based market potential have also evolved from the development of the SpectruCell technology. It is therefore perhaps somewhat disappointing that the successful achievement of so many substantial and important new milestones by the company have not been reflected yet in the stock price of ACT-US (ADVC)."May added, "I believe that the market place has not completely realized the full impact of the new relationship with the Lockheed Martin subsidiary RLM Systems in Melbourne, Australia. While the ACT engineers have been instrumental in the design, development and successful testing of the SpectruCell technology, we have been very fortunate in engaging the services of RLM to actually build the SpectruCell commercial product. RLM has an impeccable history of successfully building complex products that few companies have been able to achieve."This latest new patent application, perhaps the most important to date, is in addition to ACT`s existing patent filings which include: a method for implementing GSM on an SDR platform, a method for quadrature modulation and the core design of a software defined radio operating platform. With approximately an additional 30 proposed patent applications still to be filed, ACT-US expects to be in an extremely sound and secure position to generate substantial revenues from the licensing and royalty fees that can be generated by the protection of proprietary rights to new and evolving leading edge technologies.About Advanced Communications TechnologiesAdvanced Communications Technologies Inc.

Applications Enabled by Software Radio Technology

Bryan Tropper , Tropper Technologies Inc.

Abstract

This paper examines the use of Software Radios in the applications domain as a pervasive enabling technology that can be implemented across the telecommunication landscape. Software Radios provide robust features to the consumer in an efficient manner for the provider. The "consumer" could either be a user that is in the home, local area or in transit (on travel - nationally, internationally) or a car manufacturer who has recently developed a dash mounted navigation unit. The "provider" in this world of de-regulation could be a 3G network operator or just as likely a (wireless) ISP delivering service to a large office building via MMDS. While Software Radio is germane to commercial, civil and military uses, this article focuses on the commercial domain and illustrates the capability of the technology to provide the beginnings of "endless inventiveness" and "limitless choices".


Introduction

In it`s simplest form, Software Radios can be thought to consist of a combination of (adaptive) hardware components co-existing with a set of software modules that govern the behavior of the hardware. This combination results in re-configurable wireless systems that adapt to operational conditions, local technology standards and user needs. The Software Defined Radio (SDR) Forum, which is a non-profit group of over 100 companies from various segments of the wireless industry, recognizes a tiered definition for the level of software radios. An SDR for the most part allows software functions to define the baseband and signal processing elements and integrates capabilities to add applications blending the best capabilities of wireless and Internet networks in a cost and power efficient manner.

Traditionally, mobile wireless networks are thought of in terms of network infrastructure, base-stations and user devices such as handsets or mobiles. In this context, the network infrastructure provides the switching, control and call-processing, mobility management and servicing functions; the base stations provide the network connectivity and over-the-air interfaces to user devices; and the user devices such as hand-sets & mobiles range in a variety of classes depending upon capabilities. When SDR concepts are fully applied in the base stations and the user devices - this part of the network becomes significantly more capable than anything envisioned in the current wireless standards most of which cater to more bandwidth, speeds and applications in a given spectrum. This additional enhancement (which shall hereafter be referred to as SDR-enabled networks) is indeed the true enabler of "endless inventiveness" and "limitless choices" and is the primary focus of this article.

The cardinal feature of software defined radios is its ability to be reconfigured. This capability is the unique differentiation offered by this technology that enables service providers, manufacturers, applications developers and users with unparalleled, immediate benefits. As the traditional lines have blurred between vendors / suppliers and consumers / producers, applications are emerging at a rapid pace driven by the forces of a free (de-regulated) market. SDR-enabled networks provide a means to foster widespread adoption of these applications by promoting seamless interoperability and flexibility for consumers and far greater economies-of-scale for the providers creating the opportunity for new revenue streams and rapid industry adoption.

Applications Unique to Service providers: Beyond traditional benefits of increased quality, capacity & coverage (through the use of interference management / mitigation techniques) and "Operations and Maintenance" (OA&M), SDRs offer less hardware. The same concepts of network configuration and provisioning can be handled over several spectral bands to offer new and enhanced services. Operators with multiple spectral bands covering different network standards could deploy a simple common network to serve multiple market segments for e.g. the same infrastructure could be used to serve cellular and PCS bands, cellular and cordless bands, cellular, paging and fleet services bands; PCS and wireless-LAN bands etc. Both bases stations and user devices could be reconfigured to handle multiple standards and multiple interfaces in such a manner that both the home environment and the public network environment can be served the same way. Such combinations include, but are not limited to the offering of:
· Simultaneous delivery of telematics (The delivery of "smart" information, tailored to where consumers are and to what they are doing) and voice services
· Location based services and traditional voice and SMS
· Use of device-to-device communications protocols such as IrDA, Bluetooth, HomeRF or IEEE802.11 within the home or office and local cellular or PCS services.
· Wireless Internet via WAP, MExE or I-mode in combination with cellular or PCS and SMS
· Service Providers could also be Wireless ASPs. Wireless Application Service Providers can deliver services spanning the range from hosting m-commerce servers to providing location specific directory listings. According to the research firm IDC, the Wireless ASP business is predicted to grow to $732 million by 2004 . There are currently quite a few companies endeavoring to find their niche in this rapidly evolving market (see for example, http://www.wirelessweek.com/industry/aspdir.htm).. Most of these are relatively small companies where the importance of re-configurable hardware and scaleable service offerings take on primary roles.

The capability to reconfigure both base-stations and user devices uniquely enable the service provider to offer the following enhancements (in any or all combinations) while ensuring the support of legacy standards/systems and network scalability and extensibility into the future.
· Flexible Class of Service (as a function of application)
· Adaptive Quality of Service (as a function of application)
· Ubiquitous service assurance
· Service Differentiation
· Pay As You Go feature subscription
· Upgrade / Patch delivery

Applications Unique to Infrastructure Providers - As wireless networks are increasingly adhering to various standards, true differentiation is increasingly difficult and generally non-existent. SDR-enabled networks enhance the radio network connectivity to virtually any network directly, thus enabling the infrastructure provider to not only test-market new applications and features relatively quickly; but to also provide enhancements at the network side. One such enhancement would be the use of "Softswitches" which in principle are of the "Next Generation in Switches" that serve to extend the reconfigurable and connectivity aspects to "the entire network" under all combinations. Today, as convergence between voice and data services has changed the competitive landscape forever, the industry is quickly moving towards "multimedia" switches. Industry groups have formed around this concept (see for example, http://www.softswitch.org/) and manufacturers are rapidly developing equipment that accommodate both circuit and packet switching technologies (see for example, http://www.lucent-ssg.com/ons/softswitch/).

Infrastructure providers can further extend capabilities to bold, new features that may have never before been attempted - for e.g. the concept of the "roaming base-station". SDR-enabled base-stations could indeed be implemented in mass transport systems such as trains that virtually travel long distances at high speeds. Base stations on these trains could serve the passengers while roaming from one service-provider`s network to another and become a part of the network that could become a source of shared revenues and resources.

Applications Unique to OEMs, Tool-Developers and Applications Providers - SDR-enabled networks truly breakdown all barriers to entry for OEMs, tool-developers and applications providers. Specialization is both embraced and increasingly warranted. OEMs could concentrate on the RF, base-band or antenna part of the design to specialize in. Tool-developers could focus on the means to program new features or the means to test various aspects of the design and implementation. Applications providers could concentrate on enhancing communications, commerce and security aspects of the network or specialized services to specific industry segments such as realty, finance, securities trading etc.

Applications Unique to Device Manufacturers - The single most important application that provides both scale-economies and competitive advantage through differentiation is the ability to introduce features and capabilities in a device independent manner. As handsets and mobiles embrace larger screens and richer, smarter feature sets - they have also been characterized by device classes such as communications devices, voice phones, feature phones, smart phones, PDAs and computing devices. SDR capabilities enable the device to embed a rich set of applications modules that can be configured by the device manufacturer, service provider or applications provider to enhance a single device through a variety of classes thereby assisting both the user and the provider to pay-for-what-they-use. This is especially important when adding the concept of number portability to the device. Modular enhancements in hardware and software could virtually embed the device partially in a vehicular environment and partially with the user - allowing both entities to serve greater functions. Combinations of capabilities provide greater revenue streams to a wide range of participants such entertainment providers and toll-collectors that can be given "access" to the user device by the device manufacturer, service provider, or applications provider. As the same device can be used in a variety of applications, the device manufacturer can significantly enhance market volumes while simultaneously establishing unique ways in which to enhance capabilities of the device to differentiate themselves from competitors.

Applications Unique to users - This can literally be summed up in a single word - "choice". The user has a smarter device and a smarter interface that enables him or her to choose the application, choose the device class based on time-of-day or activity-of-the-moment and to "enable" or "disable" the capability and/or application that`s needed. Never before has a user been able to carry one single device to do all that he/she wishes at the moment that it was needed. Previously, the user had to know more and say more about their need and anticipate all possible environments in their dealings with service providers to ensure that the handset they bought did indeed communicate across the locally prevalent network standards for basic communications.
SDR-enabled handsets can query networks and adapt to the local standard alleviating the need for the user to ensure that he/she had a compatible device. Users today also carry multiple devices such as PDAs and handsets in addition to lap-tops and notebooks for wireless Internet communications, SDR enabled devices can render all of these capabilities in a single device in a smaller more easily detachable configuration for greater, richer capabilities.


Industry Challenges to SDR-enabled Networks:

· Technical - There are two broad areas in the software radio technical domain that need to be addressed. One is the obvious need to design and fabricate very powerful re-configurable pieces of hardware for a cost sensitive market within very short development cycles. This can be achieved and there are several companies working on the problem. The second issue is not as tractable. There are several alternative (complimentary) software environments under investigation for the "software" portion of Software Radio. These include debates centered around the Corba and Java environments. It is important that agreement be reached among the commercial, military and civil sectors so that the optimal path (or paths for each market sector) can be chosen.

· Standards Based - In order for industry adoption of software radio to take place, existing standards must be accommodated and adhered to. The standards being developed for Software Radio must ensure that developers of hardware and software have a common and consistent set of specifications to design towards while simultaneously ensuring that equipment works co-operatively within and amongst the existing predominant wireless standards already deployed around the world. This is crucial for testing and validation of the Software Radio enabled equipment as well as for interoperability amongst vendors.

· Testing Tools - In order for application developers to be assured that their code will behave as desired across all manufacturers` products, specifications must be adopted to code against. This necessitates the need for testing tools (see for example www.troppertech.com) to ensure compliance and conformance to a given specification. Certification is also an avenue that can be pursued (similar to "WAP" and "Bluetooth" Certification labels).

· Policy - Global roaming agreements must be constructed if there is to be true ubiquitous service anywhere the user might wish to go. Similarly, billing consolidation across types of varied services must account for the possibility that users may wish to employ one class of service for a particular application in one area, while that same user might desire to re-configure the class of service for a different application using the same Software Radio enabled device. Of course, privacy concerns are always an issue when dealing with location aware devices (an application where Software Radio will no doubt find it`s part), as is the willingness of the holders of location data to share the valuable information.


Conclusion

SDR-enabled networks are on the verge of emergence in a major way - the SDR Forum believes that it will be a mass-market phenomenon in the 4G time-frame. The factors gating acceptance such as spectral policy, specifications, and interoperability (within existing wireless standards) are already being addressed by major global players; most Forum members believe that within the next couple of years most of these areas will be worked out. Several aspects of SDR capabilities have already been adopted by major vendors (such as Nortel, Motorola and Lucent) and the complexities/capabilities of the technology are well understood in the industry.
