5.3 2.5GHz, 2.6GHz Setting Method
INOVA DAS is basically available to service 700MHz, 850MHz, 1.9GHz, 2.1GHz, 2.3GHz frequency
bands, and is designed to select one of 2.5GHz or 2.6GHz frequency band for service. So according to
the module inserted on the MHU and ERU, it can service 700MHz, 850MHz, 1.9GHz, 2.1GHz, 2.3GHz,
2.5GHz or 700MHz, 850MHz, 1.9GHz, 2.1GHz, 2.3GHz, 2.6GHz. Therefore, as the below figure for 2.5Ghz
and 2.6Ghz, the MRFU, ERFU, ERU Multiplexer of the desired frequency band should be inserted in the
INOVA DAS for service.
