Julian Oliver put together this great how to for making a tiny GSM Base Station with the BeagleBone Black, Debian, OpenBTS and a USRP.
The BeagleBone Black (AKA BBB) is a small, 1GHz ARM Cortex-A8 computer with a powerful NEON accelerator, many pin-outs (65!) and great power handling. In this HOWTO we’re going to use it as the core of a cellular base-station that can interact with mobile phones/handsets; manage calls between handsets, interface between handsets and SIP, sending SMSs, etc.
Why the BBB and not a Raspberry Pi? While lacking the graphical processing power of the R-Pi, the BBB is significantly faster, smaller and as such better suited to high-I/O applications like cellular infrastructure. More so, unlike the R-Pi, the BBB has 4Gb of on-board storage, doing away with the need for an SD Card to boot. This makes the cost of getting setup with a BBB more or less the same as that of a R-Pi but with notably better overall performance (for most applications).
A BBB can be powered from standard 5v DC or with Mini-USB. The advantage of the latter is that during development a USB Ethernet interface can also be created, allowing command-line users a convenient way of working with the board – you get both power and network connectivity over a single USB cable.
Each Tuesday is BeagleBone Black Day here Adafruit! What is the BeagleBone? The BeagleBones are a line of affordable single-board Linux computers (SBCs) created by Texas Instruments. New to the Bone? Grab one of our Adafruit BeagleBone Black Starter Packs and check out our extensive resources available on the Adafruit Learning System including a guide to setting up the Adafruit BeagleBone IO Python Library. We have a number of Bone accessories including add-on shields (called “capes”) and USB devices to help you do even more with your SBC. Need a nice display to go along with your Bone? Check out our fine selection of HDMI displays, we’ve tested all of them with the Beagle Bone Black!
