In LTE or 4G, the 3GPP defined a coexistence path for WiFi and LTE using the unlicensed bands, where an LTE subscriber could use the unlicensed 2.4 or 5 GHz bands to supplement data throughput. Known as LAA or license assisted access, LTE and WiFi can coexist, although it is unclear how many users take advantage of this technology today. 3GPP’s 5G NR-U proposals go way beyond the prior 4G work, and there is additional motivation to take NR-U further.
I had the opportunity to speak at the IEEE sponsored 5G World Forum last week in Santa Clara. My talk focused on areas of research not necessarily related to the current 5G specification or 3GPP Release 15. The purpose of my presentation was not to rehash 5G, but to instead highlight areas that will help 5G reach its potential.
The National Science Foundation (NSF), along with an industry consortium of 28 networking companies and associations that includes NI, announced the first two Platforms for Advanced Wireless Research (PAWR) initiative awards. The two platforms will be led by teams from the University of Utah, Rice University, NYU, and Rutgers University.
