New York played host to the who’s who of telecom visionaries at the inaugural Brooklyn 5G Summit on April 23-25. The summit was organized by the Network business of Nokia and New York University (NYU) and was attended by more than 150 delegates.The Summit brought together wireless/mobile industry research and development leaders from operators, regulators, partners, infrastructure vendor and academia to explore the future of 5G wireless technology with a special focus on antennas, propagation and channel modeling at higher frequency bands.The summit received worldwide coverage with live broadcasting from IEEE.
As basic requirements for 5G, the industry is targeting a system that includes peak rates greater than 10 Gbps, and cell edge rates of 100 Mbps combined with a latency target of less than 1 msec. Since the spectrum assets below 6 GHz are limited, there is a need to explore frequency bands from 6 GHz to 100 GHz to meet the requirements stated above. Due to the large spectrum assets at millimeter wave bands, a system with bandwidth in excess of 1 GHz can be used to build a 5G system with the gigabit experience and virtually zero latency. But for this technology to come to fruition, there are multiple challenges to be addressed regarding Line-of-Sight (LOS) blockage, beamforming solutions using massive antenna arrays and RFIC design. This summit was the first of its kind to address solutions and issues with respect to deployment of cellular technologies at these bands.
The future of 5G in good hands
Impressive keynote addresses were given by Mr. John Stankey, Group President of AT&T, Dr. Andrea Goldsmith (Professor, Stanford University), Dr. Seizo Onoe (CTO, NTT DOCOMO), Mr. Eric Starkloff (Sr. VP, National Instruments) and Dr. Chih-Lin I (Chief Scientist, China Mobile). Dr. Seizo Onoe and Mr. Lauri Oksanen (VP Research, NSN) spoke to Light Reading, emphasizing that there is still a lot of work to do in defining the fifth generation of wireless (5G). Dr. Onoe is definitely expecting to use millimeter wave radios, which run at much higher frequencies than traditional cellular radios, as part of any 5G deployment.
The high quality presentations from both academia and industry focused on the details of channel measurements and modeling at bands above 6 GHz including spectrum and regulatory issues. It was the common understanding that more measurements and further work on channel modeling are needed and further collaboration between industry and academia is needed to address the issues at bands above 6 GHz. This summit will now become an annual event focusing on specific 5G issues and networking around these targeted topics.
A big thank you goes out to the joint Nokia and NYU team for their flawless implementation of this important conference.
