Direct line of sight (LOS) is a luxury in wireless communications, confined largely to some dense urban environments and some mostly legacy fixed wireless access (FWA) services in relatively flat treeless settings. Yet LOS was initially thought to be critical for long distance transmission in millimeter wave frequencies above 20 GHz, in which range of up to 10 kilometers (6 miles) has now been demonstrated. In practice, the range of mmWave connections are limited to 500 meters or less in urban settings and that has been a factor limiting the spectrum’s utility. It has also been a reason why spectrum at those high frequencies has attracted far lower prices at auction than sub-GHz and midband spectrum. Indeed, the range limitations…
