sysmoNITB 2G starter kit

The sysmoNITB 2G starter kit is the combination of a sysmoNITB 2G and a sysmoBTS 1002 to provide a ready to run pre configured 2G network. Although the 2G NITB could even run directly on the sysmoBTS products, the usage of a dedicated NITB provides several advantages like

  • connection of more than one BTS

  • traffic monitoring on Abis interface

  • multiple Ethernet ports for the NITB

  • more computing power

The starter kit is suitable for a wide range of applications, including

  • IoT Testing for 2G based solutions

  • 2G related research and development

  • Production testing of 2G terminal equipment

  • Rapidly deployable 2G networks

  • Private 2G networks (PBX style use)

  • In-building coverage/capacity extension

  • Remote area 2G 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.

Starter Kit for product evaluation

The sysmoNITB 2G starter kit enables you to get quickly started and run a completely autonomous GSM network without the need for any external components. All you need to do in order to make calls and send SMS between your phones n this private GSM network is to

  • unpack the starter kit

  • connect the power supply and the antennas,

  • connect the sysmoNITB 2G with the sysmoBTS 1002 and (if desired) the internet gateway

  • insert the SIM cards into the telephones

  • power on the phones

    The starter kit includes

  • One sysmoNITB 2G

  • One sysmoBTS 1002, indoor enclosure, 23 dBm transmit power (configurable down to 0 dBm)

  • Three compatible SMA rubber antennas

  • One international power supply (110 to 240 V AC, 50/60Hz, EU/US/UK plug)

  • 20 pre-provisioned SIM cards (10 3FF, 10 4FF)

  • Printed copy of the sysmoBTS Getting Started Guide

  • Fully installed + configured software image with OsmoBTS and Osmocom CNI software

  • Customer-specific factory configuration of transmit band, ARFCN, transmit power, MCC, MNC and other parameters

  • 4 hours of remote support by sysmocom staff (e-mail based, remote login/configure)

  • USB-cable for access to serial console
