OpenAirInterface is a non-profit consortium that was founded by EURECOM and which now boasts a growing membership made up of many different types of organisations. Amongst other things, the consortium develops a 4G cellular network stack which includes an eNodeB implementation that provides support for LimeSDR and in turn LimeNET hardware.

In the above video from the BT / EE and Lime Micro hackathon a few weeks ago, Florian Kaltenberger, Assistant Professor at EURECOM, provides an introduction to OpenAirInterface, covering things such as membership, software licensing, and architecture.

Later in the day, we were treated to a live demo in which Florian ran up the eNodeB software stack on an Ubuntu system equipped with LimeSDR hardware, before going on to use the new LTE network to stream YouTube HD video content to a connected handset, while at the same time observing radio link performance via the OpenAirInterface GUI.
