PRODUCT INTRODUCTION
This indoor macro base station supports both GSM-R and LTE — the ideal solution for railways that want to prepare for evolution to an LTE broadband network. One of the most compact indoor macro base stations in the industry, the BTS3900 features a large, scalable capacity and multi-mode applications that meet the requirements of long-distance railways.
The base station cabinet contains as many as six RF modules. These multicarrier modules support both GSM-R 5.0 and LTE (eLTE). Use of this multi-radio-channel base station (and similar outdoor base station) maximizes versatility while minimizing site deployment costs.
