Last year, SureCall Founder & CEO Hongtao Zhan told RCR Wireless News that he believes that in five years, a staggering 80% of millimeter wave (mmWave) 5G networks will be made up of signal amplifiers, such as repeaters or boosters. While that remains to be seen, an announcement from Verizon that it intends to use signal repeaters from SureCall, as well as FRTek, to increase its 5G Ultra Wideband — or mmWave — coverage does indicate expanding interest in these types of solutions.
