Query: A Comparison Study of Cellular Deployments in Chicago and Miami Using
  Apps on Smartphones   Cellular operators have begun deploying 5G New Radio (NR) in all available
bands: low (< 1 GHz), mid (1 - 6 GHz), and high (> 24 GHz) to exploit the
different capabilities of each. At the same time, traditional 4G Long Term
Evolution (LTE) deployments are being enhanced with the addition of bands in
the unlicensed 5 GHz (using License Assisted Access, or LAA) and the 3.5 GHz
Citizens Broadband Radio Service (CBRS) resulting in throughput performance
comparable to 5G in mid-band. We present a detailed study comparing 4G and 5G
deployments, in all bands in Chicago, and focused mmWave measurements and
analysis in Miami. Our methodology, based on commercial and custom apps, is
scalable for crowdsourcing measurements on a large scale and provides detailed
data (throughput, latency, signal strength, etc.) on actual deployments. Our
main conclusions based on the measurements are (i) optimized 4G networks in
mid-band are comparable in both throughput and latency to current deployments
of 5G (both standalone (SA) and non-standalone (NSA)) and (ii) mmWave 5G, even
in NSA mode, can deliver multi-Gbps throughput reliably if the installation is
dense enough, but performance is still brittle due to the propagation
limitations imposed by distance and body loss. Thus, while 5G demonstrates
significant early promise, further work needs to be done to ensure that the
stated goals of 5G are met.
