3.5G starter kit

For many years the sysmoNITB (aka Network in the Box) has been known as a versatile solution to setup GSM/GPRS networks quickly and efficiently. Now, sysmocom introduces the sysmoNITB 3.5G: the next step in Free and Open Source mobile network technology. The sysmoNITB 3.5G paired with a supported hNodeB enables a wide range of applications, including:

  • IoT Testing for 3G based solutions

  • 3.5G related research and development

  • Production testing of 3G/3.5G terminal equipment

  • Rapidly deployable 3.5G networks

  • Private 3.5G networks (PBX style use)

  • In-building coverage/capacity extension

  • Remote area 3.5G deployments, utilizing any IP-based satellite back-haul service

The sysmoNITB paired with an hNodeB runs a completely autonomous small 3G network. All core network elements like hNodeBGW, MSC/VLR and HLR are part of the NITB.

Limited edition starter kit for product evaluation

For a limited time and as long as stocks last, we are offering the sysmoNITB 3.5G starter kit limited edition. The starter kit enables you to quickly get started and run a completely autonomous 3.5G network without the need for any additional external components.

The starter kit is the ideal entry point for your first steps in setup and operation of mobile networks. Due to its pre-configuration and the complete delivery you can start with a working network. You can concentrate on your application much faster than setting up everything from scratch.

All you need to do in order to make calls, send SMS between your phones and use data services in this private 3.5G network is to:

  • unpack the starter kit

  • connect the power supplies

  • connect the sysmoNITB 3.5G with the hNodeB and (if desired) the internet gateway

  • insert the SIM cards into your telephones (phones not included!)

  • power on the phones

The starter kit includes

  • one sysmoNITB 3.5G

  • one nano3G femtocell (hNodeB)
