Introducing sysmoBTS (data sheet)
The sysmoBTS 2100 is a new, low-power, small-formfactor IP-backhaul GSM BTS for medium coverage outdoor applications. Replacing the popular sysmoBTS 2050 it offers higher output power, integrated cavity duplexers and bigger maximum reception area. Therefore 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)
The IP66 rated sysmoBTS 2100 is intended to be mounted directly to the antenna pole in close proximity of the antennas. This keeps RF cables short and avoids the losses associated with long coaxial cables. Integrated duplexers for both ports reduce the amount of external components.
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!
