Ericsson UKL 401 72/11 R2A RAU2 X 38/11 Remote Antenna Unit

The Ericsson UKL 401 72/11 R2A RAU2 X 38/11 is a remote antenna unit designed for use in Ericsson distributed radio systems and indoor coverage solutions. This unit operates as part of a distributed antenna system (DAS), where RF signals from centralized base station equipment are distributed to multiple remote antenna units positioned throughout a service area. By placing antenna units closer to end users, the system improves signal strength, expands wireless coverage, and enhances overall network capacity in environments where macro base station signals may be weak or obstructed.The RAU2 X 38/11 unit receives RF signals transmitted from base station equipment via feeder cables or fiber-based distribution networks and transfers them to the connected antenna for local signal transmission. This architecture helps minimize signal losses over long transmission paths and ensures consistent wireless connectivity across complex indoor and semi-indoor environments. Such systems are widely used in large facilities including airports, stadiums, office complexes, shopping malls, tunnels, and underground transportation systems where reliable cellular coverage is required.

Built with telecom-grade RF components, the Ericsson RAU2 X 38/11 provides stable signal distribution and reliable long-term performance. Its robust mechanical design allows continuous operation in demanding telecom environments while ensuring seamless integration with Ericsson distributed radio infrastructure.

The Ericsson UKL 401 72/11 R2A RAU2 X 38/11 Remote Antenna Unit enables mobile network operators to extend coverage areas, improve signal quality, and maintain consistent wireless communication services in distributed and indoor network deployments.
