Unified BTS/BSC
In GSM/GPRS networks, the YateBTS implements all the functions of the base transceiver station (BTS) and the base station controller (BSC). This leads to a unique, lightweight unit – the SatSite – performing the role of the entire base station subsystem. This allows it to work directly with the unified core network YateUCNTM.
The SatSite is an intelligent radio access network component communicating directly with the YateUCNTM to simplify the network infrastructure.
The SatSite uses software-defined radio on commodity hardware instead of special-purpose FPGA or DSP boards, reducing the size, cooling and shelter requirements and power consumption of the BTS, resulting in lower civil infrastructure costs.
Unifying the Base Transceiver Station (BTS) and the Base Station Controller (BSC) eliminates the costly Abis interface for traffic and signalling.
The SatSite BTS performs all the functions of the BSC and partially of the MSC (Mobile Switching Center) and the SGSN (Serving GPRS Support Node) – mobility, power and frequency management, handover.
For handover, the SatSite contains the IP list of all the neighboring SatSite units. The SatSite base stations use the SIP protocol to transmit between each other the frequency, the Base Station Identity Code (BSIC) and the Cell-ID of each base station, since the architecture does not included BSCs.
The YateBTS SatSite integrates a parts of the MSC and the SGSN, any custom features at BSC-MSC level (such as local call switching and local IP access) can be supported.
With no BSC, scalability of the core can be easily achieved because each SatSite BTS can communicate, at any point, with any YateUCN core in the network.
Reduced idle traffic and latency requirements make satellite backhaul feasible.
Abis over IP
BSC and the MSC handle all the critical operations in the network, while the BTS only manages the transceiver and the radio communication with the mobile device.

Conventional GSM architecture results in large costs for civil works and equipment, high power requirements, costly traffic and signalling interfaces, limited flexibility to update, reprogram, or optimize the network functions.
