Remember when the MNO crowd promised that running LTE in 5 GHz unlicensed spectrum would not interfere with WiFi networks? Well, it seems that they have misled us rather badly, based on a study from the University of Chicago, led by a potentially jaded former FCC CTO. This bodes poorly for the network densification needed for proper 5G coverage and reflects badly on the FCC’s assurances. Based on the University of Chicago’s study, which it thinks is the first of its kind, WiFi throughput can degrade as much as 97% when coexisting with Licensed Assisted Access (LAA), whereas LAA throughput only degrades 35%. Notably, AT&T – which has been deploying LAA since 2017 – thinks people are going to start…
