Microwave backhaul technology continues to impress, repeatedly exceeding capacity limits and reaching performance levels only believed possible for fiber solutions. It plays a significant role in providing reliable mobile network performance and is well prepared to support both the evolution of LTE and the introduction of 5G. Efforts are now underway to enable microwave backhaul beyond 100GHz, capitalizing on the rapid evolution of high-frequency semiconductor technologies that support devices operating beyond 100GHz.
The latest Ericsson Technology Review article explains the concept of microwave backhaul beyond 100GHz. It charts the course toward 100Gbps transport solutions and presents a working prototype of a D band transceiver module that Ericsson Research has developed together with researchers at Chalmers University of Technology in Gothenburg, Sweden.
