Alcatel-Lucent adds another first as it drives broad range of 5G industry development programs toward its Network 2020 vision - Seite 2

Tod Sizer, head of wireless research at Bell Labs said: "Mobile networks are quickly becoming our lifeline for all types of communications. Things such as growing industrial usage, traffic cams, sensors as well as the continued growth of consumer data, are going to severely challenge current networks. Our plan for 5G is to enhance the network in a converged way that will allow service providers to maintain the quality users expect, deliver the capacity they demand, and provide the ability to support new applications and services, such as IoT and M2M type."

In addition to the 5GNOW project, for the last several years Alcatel-Lucent and its industrial research arm Bell Labs have been active in a range of key research initiatives with several universities, industry stakeholders, standards bodies and industry consortia. Recent examples include joining the Technische Universität (TU) Dresden's 5G Lab and collaboration agreements with Korean Telecom and NTT DOCOMO.

Many of the consortia are initiated or recognized by the EU commission, most of them in connection with the 5G PPP. These include:

• FANTASTIC-5G
• 5G Norma
• mmMAGIC
• Flex5GWare
• Metis-II

About the 5GNOW Project
Today's dominant air interface, Orthogonal Frequency Division Multiplexing (OFDM), is the basis for LTE and LTE-Advanced and has a tightly synchronized structure that requires a significant amount of signalling overhead to establish a connection. This enables the high data rate transmission required for web and video based traffic but does not support the efficient transmission of short burst and non-urgent traffic associated with an Internet of Things (IoT) as well as today's short burst traffic such as Instant Messaging (e.g. WhatsApp), acknowledgements, or 'keep alive' messaging. The 5GNOW proposals modify OFDM with adaptive filtering and advanced signal processing to address both sets of requirements, resulting in an air interface that:

• Increases the maximum number of device connections to an individual cell site by a factor of over 100 times
• Decreases the delay associated with connectionless access to less than 1 millisecond for Machine-Type-Communications (MTC)
