While the traffic between Cellular Base Transceiver Station and Telephone Exchange has been through the optical fibre as the standard transmission method, for the place where to deploy the optical fibre is difficult such as the river side, the road crossing, the environmental protection region and the island, Microwave Transmission is being used as the alternative but the ultimate solution.

JRC have developed the State-of-Art High Speed Transmitting Radio at 11/15/18/22GHz for the backhaul and these equipment are provided to Mobile Phone Operator and these have been the part of the infrastructure successfully.

This document is to describe the manufacturing technology and production engineering of the equipment.
