After demonstrating that it was possible to take wireless backhaul to 40Gbps earlier this year, Deutsche Telekom and Ericsson have returned to take a 1.5 kilometre link to 100Gbps.

The trial was once again conducted at the Deutsche Telekom Service Center in Athens and it utilized Ericsson's Mini-Link 6352 microwave solution. To achieve such improved speeds, the recent trial used 8x8 line-of-sight Multiple-Input Multiple-Output in a 2.5 GHz channel within the 70 to 80GHz range.
