Deutsche Telekom (DT), its Greek subsidiary Cosmote and Swedish vendor Ericsson have been trialling W-band spectrum (92GHz-114GHz) for wireless backhaul for 5G and future 6G networks. Tests carried out at Cosmote’s headquarters in Athens recorded speeds of 5.7Gbps over a 1.5km distance and data rates topped 10Gbps over 1km.
Konstantinos Chalkiotis, Vice President of 5G Solutions, Access & Home Networks at DT, commented: ‘The evolution towards future-proof, cost-efficient and high-capacity wireless backhaul networks will play an important role to accommodate growing traffic demand, increased site location (including small and pico cells) and extend 5G services in the future. The results of our innovation trial with Ericsson confirm the feasibility of using higher frequency bands with wider channels as another solution in our portfolio to deliver high capacity and high performance backhaul for our customers in the 5G era. We hope soon to see those solutions brought into real production in a cost-efficient manner.’
