Ericsson Links LTE main and Remote Radio Units by Microwave

Ericsson has demonstrated the ability to link LTE main and remote radio units using microwave connections with 2.5 Gbps of capacity. Typically, fiber is used to connect main and remote radio units (RRUs), however Ericsson believes microwave radios may be more practical in some circumstances, including small cells and heterogeneous networks (hetnet).


In the tests, conducted at the Ericsson premises in China, the microwave connection between the main unit and the remote unit was provided by a MINI-LINK PT, working in the E-band (70-80GHz). The microwave link provided capacity of 2.5Gbps, which is sufficient for a wireless main-remote system in compliance with Common Public Radio Interface (CPRI) standards. This is one example of new applications with high-capacity packet microwave products.
