Nortel Networks Corp. announced it is collaborating with an international group of universities to develop technologies for 4G mobile broadband applications such as video, mobile TV and other multimedia services.

The company is expanding existing research partnerships with universities such as the University of Waterloo in Canada, The University of Texas (UT), and National Taiwan University (NTU). Nortel has also formed partnerships with Mera Networks in Russia and Technische Universitaet Ilmenau in Germany.

"Nortel's investigations with these universities are designed to improve spectral efficiency, and decrease time to market for Nortel's 4G mobile broadband solutions," the company said. The solutions include Mobile WiMAX, Long Term Evolution and Ultra Mobile Broadband cellular standards.

Nortel is working closely with the Coding and Signal Transmission (CST) group of the University of Waterloo to increase the capacity of the future wireless networks through advanced multi-user transmission techniques. As part of its expanded partnership, Nortel is utilizing Waterloo's on-campus research facilities to allow students and faculty to test and develop next-generation wireless technologies.

As an affiliate sponsor of UT at Austin's Wireless Networking and Communications Group, Nortel has been working with the university on the development of advanced 4G mobile broadband technologies, including MIMO-OFDM.

Nortel and UT also have plans to work on advanced multi-user MIMO technologies and relay links to extend the coverage of cellular base stations. The goal is to enable a "true broadband" 4G experience everywhere by blanketing an area with small, relay access nodes, rather than costly base stations, to ensure high-speed, high-bandwidth capabilities.

The work done with NTU is expected to deliver enhanced capabilities over 4G WiMAX such as multimedia video conferencing with voice, video and Internet messaging, and location-based applications.

Nortel is also working with Mera Networks, a Russian Telecom R&D services provider and Technische Universitaet Ilmenau in Germany to develop advanced combinations of spatial processing and MIMO technologies. These wireless radio techniques are said to improve network performance and increase capacity by re-using spectrum resources by up to a factor of four over conventional systems.
