To support 5G, Mitsubishi Electric Corporation has developed a digitally controlled GaN power amplifier (PA) covering 1.4 to 4.8 GHz with more than 40 percent efficiency.

The world is on the verge of a 5G revolution, and T-Mobile firmly believes everyone needs to benefit, not just the few. Along with Intel and Ericsson, the Un-carrier just took another step toward delivering nationwide 5G, pulling off the world’s first 5G data call and video call on 600 MHz (including successful uplink and downlink communication), both on a live commercial network.

Keysight Technologies has extended its collaboration with China Information and Communication Technology Group (CICT) with a new purchasing framework agreement, strengthening the two companies' commitment to develop 5G technology.

ZTE Corp. takes the lead in completing IMT-2020 third phase 5G test for core network performance stability and security function, fully verifying the maturity of ZTE's 5G core network.

5G has become an arms race, with the U.S. and China the protagonists. The core issue is a longstanding concern about Huawei and ZTE enabling the Chinese government’s espionage, concern the two companies’ infrastructure equipment has, or could have, back doors to China.
