LibreCellular: Easy 4G Cellular Network with LimeSDR and Intel NUC
We recently came across the LibreCellular project which is aiming to make it easy to implement 4G cellular networks with open source software and low cost SDRs. The project appears to be in the early stages, and seems to be focusing on deploying and modifying existing open source 4G basestation software known as srsRAN which will be used with a particular combination of hardware in order to create a reliable and easy to set up 4G basestation solution.
The reference hardware that they are recommending consists of an Intel NUC single board computer ($699), LimeSDR ($315), LimeRFE front end filtered power amplifier ($699), and Leo Bodnar Mini Precision GPS Reference Clock ($140). All together you can create a 4G basestation for around $1850.
why? What for? I could see maybe in an unregulated 3rd world country or something…but…wow. And is the reason why I get alerts on my phone screen that say something to the effect of the current tower your phone is connected to may not be a valid service provider? Cannot find a valid roaming list.
