2G+4G BTS

The SageRAN 2G+4G BTS is a dual-mode base station designed for operators that require both legacy 2G services and 4G broadband connectivity. Built on a common BBU and RRU architecture, it supports flexible deployment of GSM and LTE networks on a unified platform.
The solution is well suited for network replacement, basic voice and SMS services, low-rate data, remote-area coverage, mobile broadband, and IoT applications. With support for IP-based transport over IPRAN or satellite backhaul, it can be deployed in a wide range of network environments and connected to the BSC and core network through a centralized switching architecture.
The 5G+LTE BBU is the baseband processing unit of the SageRAN`s XLink™ 5G+LTE distributed small cell solution. It is a small and low-power indoor distributed small base station that provides 5G and 4G mobile signal coverage for indoor scenarios through access to fixed broadband, proprietary backhaul, and other means to the mobile core network. It significantly improves user capacity and provides users with a good network experience, in combination with the expansion unit (EU) and remote radio unit (RRU).
