Description

This project aims to use the LimeNET Micro Software Defined Radio to set up a public GSM network using Yate and YateBTS. The rationale for this project was to study and experiment mobile communications and the GSM protocol with a low-end device. It creates simple and basic GSM network for SMS and voice calls running on a LimeNET Micro with a Raspberry Pi CM3 board flashed with Ubuntu 20.04 LTS.
