2G Base Station Tutorial - Part Two: Connect Phones, Make Voice Calls, Send SMS's, Use GPRS Data

It's been a while since I have visited any topic relating to GSM cellular technology in my videos, but many of my viewers have been requesting an in-depth tutorial on how exactly to deploy a 2G base station transceiver using software defined radio.

Using a BladeRF xA4 and some software for Linux called YateBTS, it is possible to operate a small experimental cellular network which will allow two mobile phones in your lab environment to make telephone calls, send SMS messages and browse the internet via a GPRS data connection.

Join me in part two today, where I demonstrate how to initialize the base station software and hardware. I then proceed to connect my two mobile phones to it, and I finish off the video by showing how it's possible to make telephone calls, send SMS messages and browse the internet (very slowly) via GPRS.

Keep your eyes peeled for part 3, where I will show my viewers how to 'tap' the data flowing across the 2G base station. I will also detail how YateBTS can be used an experimental IMSI catcher. And if I have time, I'll also cover some hints and tips for troubleshooting common problems.

Thanks very much for watching!


DISCLAIMER:

Deploying experimental cellular base stations using software defined radios will require you to transmit signals on portions of the radio frequency spectrum that you are not permitted to use. This CAN and WILL cause destructive interference to licensed radio services operating on those frequencies. I WON'T be held responsible for any legal trouble you get yourself into because you got a knock on the door from the spectrum regulation authority in your country. It is advisable to NEVER follow this tutorial, EVER!
