Discontinued: sysmoBTS (data sheet)
The sysmoBTS 2050 is a new, low-power, small-formfactor IP-backhaul GSM BTS for medium coverage outdoor applications. It offers supreme cost efficiency and is suitable for a wide range of applications, including:
Rural cellular networks in lowest-ARPU regions
Rapidly deployable GSM networks
Private GSM networks (PBX style use)
Remote area GSM deployments, utilizing any IP-based satellite back-haul service
Offshore wind farms, oil rigs
Onboard coverage on maritime vessels (ferries, cruise ships, commercial vessels)
Benefit from sysmocom's world-class experience in all areas of cellular networks from RAN to core network, permitting flexible integration of other network elements like BSC into the BTS itself.
As the only BTS world-wide, sysmoBTS permits you to run a completely autonomous small GSM network from within the BTS. No external BSC/MSC/HLR/VLR required!
