Outdoor Distributed Antenna System
The system provides cellular coverage due to serial distribution of a base station (BTS) sectors.
oDAS RADIUS is intended to provide cellular coverage along railways, roads and rural areas. The system allows increasing network capacity efficiency.
The system is designed for integration with LTE FDD, UMTS, GSM (GSM-R) networks, and provides serial distribution of a base station (BTS) sectors (frequency bands) at the distance of 60 km reducing infrastructure cost (CAPEX/OPEX).
The RADIUS FSC unit is installed at the site with a base station and receives the GSM, LTE, UMTS carriers from it. Then the unit converts them and transmits via MWL or fiber optic over a distance.
The oDAS RADIUS FSR unit is installed at the remote site. It receives the carriers using MWL or fiber optic and provides creation of several sectors similar to that of the BTS. In addition, it amplifies and transmits the received signals further along the line to the next site equipped with oDAS RADIUS products.
