After conducting extensive pioneering research into millimeter wave technology, NYU Wireless is offering an open source 5G channel model and simulation tool that anyone can download. It's suitable for industrial, academic or 3GPP simulations, NYU Wireless says.
The download includes complete statistical channel model and simulation code for generating realistic spatial and temporal wideband channel impulse responses. Measurements and 5G millimeter wave channel models were developed from 2 to 73 GHz.
In 2014, researchers at NYU Wireless, led by founding director Ted Rappaport, reported on promising research that at the time indicated millimeter wave frequencies (30 to 300 GHz) could be used much more practically than previously believed. In particular, they said over 14 GHz of available spectrum exists in the 28, 38/39, and 73 GHz bands, making these bands great candidates for increasing capacity by several orders of magnitude over traditional cellular and Wi-Fi allocations.
Today, Tier 1 U.S. wireless operators are conducting tests in the millimeter bands in anticipation of 5G services, and FCC Chairman Tom Wheeler has promised that the U.S. will make 5G spectrum available before any other nation, with the FCC's Spectrum Frontiers proceeding schedule to be complete this summer. The proceeding is the topic of a workshop the FCC is hosting on Thursday, March 10, where Rappaport is schedule to deliver a keynote.
The release of the 5G channel simulator software should be a big help to those who are studying the millimeter wave space for their own interests. While millimeter wave spectrum offers opportunities to increase capacity, little was known about the channel propagation characteristics for mobile access networks in dense urban environments until NYU Wireless conducted its experiments.
Their research has included everything from propagation measurements to radio channel modeling, system capacity analysis and simulation, antenna design, RF safety measurement and modeling techniques, and network design for use at millimeter wave frequencies. Rappaport founded NYU Wireless after establishing two other wireless communications research centers, one at Virginia Tech and the other at the University of Texas at Austin.
