Deutsche Telekom has demonstrated a millimeter wave link with a data transmission rate of 40Gbps at the Deutsche Telekom Service Center in Athens.
Ericsson and Deutsche Telekom achieved four times greater data throughput compared to current commercial millimeter wave solutions to prove the commercial viability of future wireless backhaul technology.

Alex Jinsung Choi, SVP Strategy & Technology Innovation, Deutsche Telekom, said: “Fiber is not the only option for backhaul. We have demonstrated fiber-like performance is possible with wireless backhauling/X-Haul solutions.”

The test focused on the stringent latency requirements in 5G network architecture to support low latency use cases. The test achieved less than 100 microseconds round-trip latency performance, confirming wireless backhaul technologies’ contribution to meet the network-specific latency target.

Deutsche Telekom has completed the trial over a hop distance of 1.4 kilometers in the millimeter wave (E-band) spectrum. Deutsche Telekom engineers used Ericsson’s mobile transport technology including Ericsson’s MINI-LINK 6352 microwave solution and Router 6000.

Per Narvinger, head of Product Area Networks, Ericsson, said: “Microwave is a key technology for mobile transport by supporting the capacity and latency requirements of 4G and future 5G networks.”
