Introducing sysmoBTS 1002 (data sheet)

sysmoBTS 1002

The sysmoBTS 1002 is a new low-power, small form factor IP-backhaul GSM BTS. It offers supreme cost efficiency and is suitable for a wide range of applications, including:

  • Rural cellular networks in lowest-ARPU regions

  • GSM related research and development laboratories

  • Production testing of GSM/GPRS terminal equipment

  • Rapidly deployable GSM networks

  • Private GSM networks (PBX style use)

  • In-building coverage/capacity extension

  • Remote area GSM deployments, utilizing any IP-based satellite back-haul service

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, the sysmoBTS 1002 permits you to run a completely autonomous small GSM network from within the BTS. No external BSC/MSC/HLR/VLR required!

sysmoNITB 2G starter kit

Like most GSM network components, the installation, configuration and operation of GSM networks requires some know-how on GSM networks and protocols.

In order to ensure the best possible customer experience, we are offering a sysmoNITB 2G starter kit which is our turnkey solution. Just unpack it, power it up, insert SIM cards into phones and run your own single-cell autonomous network. The starter kit includes a fully pre-configured system with 10 SIM cards as well as indoor antennas and four hours of remote support for configuration and installation.
