The sysmoNITB appliance (data sheet) is a small form-factor computer with:
access to the sysmocom package upgrade feed
a set of 10 pre-provisioned SIM Cards.
Using the sysmocom NITB appliance and a modern IP capable BTS you will be able to run a private GSM network with your provisioned subscribers.
This solution allows to
place voice calls and exchanging SMS between any provisioned subscribers
sending/receiving SMS from external applications via the control interface
sending/receiving SMS from external applications via the built-in SMPP 3.4 interface
providing GPRS services (mobile data) to provisioned subscribers
use the wireshark GSM protocol decoders to trace any communication between the subscribers and the network
The sysmoNITB appliance is the ideal environment to study GSM and do experiments.
All software components on the sysmoNITB are Open Source Software components. This allows full analysis, research as well as development and rapid prototyping of custom GSM-related applications.
