China Mobile Hong Kong (CMHK) has connected what it says is the territory’s first 5G voice and video call. Besides a local call, a cross-border call was also made to the Chinese capital Beijing, Xinhua reports. Sean Lee, director and chief executive officer of CMHK, said 100MHz of spectrum was used for testing purposes, and the speed of the network would become even higher if 200MHz of spectrum was used. 5G network users can look forward to transmission rates ten to 20 times faster than 4G, he added. CMHK is the third-largest of Hong Kong’s four mobile network operators (MNOs).
