A PCU (Packet Control Unit) is one of the two GPRS elements in the BSS. It implements the RLC and MAC layers of the GPRS Um (radio) interface on the MS-facing side, as well as the Gb Interface (NS, BSSGP) on the SGSN-facing side.
OsmoPCU is the Osmocom implementation of this PCU functionality.
We can provide porting services to port OsmoPCU (together with OsmoBTS) to your specific PHY, BTS hardware or SDR platform.
sysmocom is offering different support levels for the Osmocom based cellular network elements. This gives you the trust to get support to your needs in the most effective and economic way.
