Free and open source solutions now exist for every component that is required to create a 4G cellular (LTE) network, all the way from the radio access network (RAN) and core, to services which are used for integrated voice (VoLTE). Creating a fully functional mobile network is the next logical step, but this requires overcoming the final remaining technical hurdles.
This project will provide end-to-end integration of a FOSS technology stack for 4G networks, via a validated hardware and software configuration that is subjected to appropriate testing.
Together with additional tooling and documentation for repeatable deployment, the project will make it far easier to create a self-contained 4G network than ever before. This is particularly timely given the availability of low cost software-defined radio (SDR) hardware, coupled with the efforts of wireless regulators to provide increased access to spectrum for private and community LTE networks.
Further details, including an overall architecture and roadmap, will provided in due course (target 1st February 2021).
This project was funded through the NGI0 PET Fund, a fund established by NLnet with financial support from the European Commission’s Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 825310.
