sysmoBTS 1020
Introducing sysmoBTS 1020 (data sheet)
The sysmoBTS 1020 is a new, low-power, small-formfactor IP-backhaul GSM BTS for medium coverage outdoor applications. Its key features are:
single TRX, 2 W RF output power
supreme cost efficiency
sysmoBTS 1020 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.
