The Ericsson UKL 401 11/58 R3B RAU2 23/58 is a remote antenna unit designed for use in Ericsson distributed radio and coverage extension systems. This unit is deployed as part of a distributed antenna system (DAS) or remote radio infrastructure, where it helps extend cellular coverage by distributing radio signals from centralized base station equipment to remote locations within a coverage area. By positioning antenna units closer to end users, the system significantly improves signal quality, network reliability, and overall coverage performance.The RAU2 23/58 remote antenna unit operates as an interface between the distributed radio network and the antenna system. It receives RF signals transmitted from the base station through feeder or fiber connections and delivers them to the connected antenna for local radio coverage. This architecture is commonly used in complex indoor and semi-indoor environments such as large office buildings, stadiums, airports, underground transportation systems, and tunnels where macro base station signals may not reach effectively.
Engineered with telecom-grade components, the unit provides stable RF signal handling and reliable long-term performance. Its durable design supports continuous operation in demanding telecom environments while ensuring efficient integration with Ericsson network infrastructure. The Ericsson UKL 401 11/58 R3B RAU2 23/58 Remote Antenna Unit enables network operators to expand coverage, improve signal distribution, and maintain consistent wireless service quality across challenging deployment scenarios.
