Multi-band DAS
5G/4G Multi-band Digital DAS (N41/N78)
The 5+4G digital DAS is divided into two units, the Master Unit (MU) and Remote Unite (RU). Digital DAS is a new system solution that extends the radio frequency part of the base station to serve multiple frequency bands by means of digital processing, digital fiber transmission and software radio technology. Support the integration of multiple systems and one network coverage, to solve the problems of difficult Macro station construction, high cost, low rate of return, improve user experience, reduce the cost of network construction. At the same time, through wireless remote monitoring and management, the operation cost is reduced to the greatest extent, and the quality of network signal is improved. At present, it is mainly used in tunnel, village in city, basement, and other scenarios of wireless network optimization construction.
