Deutsche Telekom hits 140Gbps peak on wireless 5G backhaul link

Wireless backhaul is often neglected when talking about 5G, with many assuming that every base station will require high quality fiber. However, in dense networks, it will often be impractical for every cell to have a fiber link, and Deutsche Telekom is looking to use microwave for some bigger connections too. The German telecoms group conducted tests in its R&D center in Athens, Greece, with Ericsson, which achieved data speeds of over 100Gbps in a live test on prototype 5G networks. The test, said DT, saw consistent speeds of 100Gbps over a microwave link spanning 1.5 kilometers, with the connection maintaining that data rate for 99.99% of the time, while peak speeds were 140Gbps. “Advanced backhaul solutions will be needed…
