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:

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)

The sysmoBTS 1020 is intended to be mounted directly to the antenna pole in close proximity of the antenna.
