In a report dated 6 April 2021, Deutsche Telekom, Cosmote, and Ericsson provided details on trials at Deutsche Telekom’s Mobile Backhaul Service Center in Cosmote headquarters, Athens, where the partners successfully proved the viability of frequency bands beyond 100 GHz, such as W band, for multigigabit wireless backhaul capacities for 5G and 6G.
Indeed, 5G’s increasing capacity demands also apply to transport. Just as RANs are starting to use higher frequencies such as 26 and 28 GHz to allow more capacity, wireless backhaul is also looking into the possibility of higher frequencies with broader channels to enable greater capacities.
Wireless backhaul currently uses frequency bands from 4 to 80 GHz to support 5G transport requirements.
