Signals Research Group - SRG just released a paper on behalf of Qualcomm which looks at 5G NR mmWave performance. Emil Olbrich and I checked out the use of wider DL/UL channels in Chicago, which delivered a near doubling in user data speeds and overall capacity. Downlink speeds well above 3 Gbps are achievable in today’s networks with even higher data speeds possible with simultaneous use of multiple LTE radio channels. We also took a road trip to rural Wisconsin to document Gbps speeds at multi-km distances, while closer to home we documented Gbps speeds with buildings and trees completely blocking the “view” of the serving cell. It is impossible to extrapolate mmWave performance with a smartphone to what we observed with a high-power CPE. You must see it to believe it. We even ventured out to SoCA to observe in-building mmWave coverage in places where you would never expect it – stairwells, enclosed conference rooms and remote hallways with no visibility of the serving cell. We only used commercially available smartphones and networks. Thanks to Accuver Americas, Rohde & Schwarz, and Spirent Communications. You can check out the adjacent video for a mmWave tour of Minneapolis or download the paper. https://lnkd.in/eTrHGxJ

3yLooks good for a clear day. Was any performance data taken during a light snow or rain shower? Wondering how much RF attenuation would be experienced in the 5G system there during snow or rain - especially since some of the nodes are a couple blocks away.
