The use of millimeter-wave spectrum has evolved in the 5G era, and these high-band airwaves are playing significantly different roles in current networks than they have in previous generations of cellular technology.
High-band frequencies used to primarily appear in mobile networks as point-to-point backhaul links, which were often relied upon by public safety and other private networks, as well as in some cases for backhaul of consumer-facing cellular networks. Commercial network backhaul systems operate in spectrum up to 90 GHz.
Given that history, it’s not surprising that one of the first mmWave applications that emerged for commercial use has been Fixed Wireless Access, according to Russel Lindsay, senior product manager for Anritsu’s handheld field instruments.
