A 5G RRU equipment selection guide helps a 5G network manager select appropriate RRUs. While Selecting 5G RRU, power output, massive MIMO compatibility, and supporting frequency bands need to be considered. For example, the RRU must support the frequencies if an operator intends to provide high speed data services using millimeter-wave frequencies. The scale efficiency of the RRU and energy consumption also require consideration. This guide ensures that operators select appropriate RRUs that meet the stringent requirements of the 5G networks.
