RRUs and RF Combining Circuit Sharing Solution for Sites with Space Constraint

Abstract

Base station network infrastructure cost continues to be among the biggest CAPEX for mobile operators. One of the options to optimize the cost is by sharing the infrastructure with other operators. Elements which can be considered for sharing are structure space for antennas, equipment space for radio equipment and incoming power supply. Radio equipment will take up more than half of the space at site. And among the radio equipment installed at site, Remote Radio Unit (RRU) is the unit which usually occupies the biggest space due to the quantity of items which are, physically heavy and bulky, multiple based on technology deployed and they generate a lot of heat. This proposal will provide one of the RRUs sharing solution for sites with space constraints but need to accommodate a high number of RRUs and accessories.
