LTE Demo with LimeSDR and OpenAirInterface

The OpenAirInterface Software Alliance are working towards the development of a 5G cellular stack that will run on commercial off-the- shelf (COTS) hardware, and they already have a functioning 4G (LTE) implementation that runs on a commodity Intel platform equipped with SDR.

In a video that Raymond Knopp of EURECOM shared over the weekend, we can see the OpenAirInterface eNodeB (base station) software being used with LimeSDR to create a 10MHz LTE cell. Following which a handset is shown connecting to the new network and via this to the Internet, before browsing the OpenAirInterface website and streaming video.

Finally, a network speed test is performed and we can see an impressive rate of around 20Mbps downlink and uplink.

To find out more information about OpenAirInterface, including links to the code, installation instructions, documentation and tutorials, see the OAI wiki.
