Within the year, hoping to increase fixed wireless speeds 50+%. Telecom Italia deployed a Kumu unit in Turin for LTE backhaul using the full duplex bandwidth. The 3GPP standard has included "LTE Relay" since 2009 but that hasn't been practical. Qualcomm is sampling the Snapdragon 820 Cat 12 LTE chip, capable of 600 megabits. TI thinks they've found a backhaul solution.
World-leading engineers believe wireless capacity will grow at least 50x in coming years. They include Marconi Prize winners Marty Cooper, Arogyaswami Paulraj, Henry Samueli and Vint Cerf. MIMO will yield at least a 10X improvement. AT&T and Verizon both have enough unused spectrum to double or triple current LTE capacity. Full duplex has the potential to double everything, and the researchers are confident of at least a 50% improvement most places. Back of the envelope, I believe a 25X increase in wireless capacity is possible without raising capital spending.
