Kumu Networks is best known for its work in full duplex radio, a technique which promises to increase spectral efficiency dramatically because it allows transmit and receive to occur in the same channels. Though this is a technology that has already been implemented in some wireline networks, it is considered cutting edge in wireless, and has been heavily associated with 5G. Like many ‘5G’ innovations, however, it is likely to find its first commercial home in other sectors, such as backhaul and WiFi. So Kumu’s first trials were in fixed wireless/backhaul, and the RF chip it has released this month for customer evaluation seems to be targeted primarily at WiFi, and particularly at the new spectrum allocations, in the 6…
