The FlexWave™ Base Station Controller (BSC) provides common control for both the indoor FlexWave nanoBTS and the outdoor FlexWave microBTS. Built with a modular and flexible IP-based architecture, the FlexWave BSC uses IP connectivity to communicate with the FlexWave BTS units, while offering a standard circuit-based A-interface to the MSC and a standard circuit-based Gb interface to the SGSN. There is also an option to connect into core network architectures that employ a softswitch MSC.
