Project update 5 of 9
Back in 2017 we demonstrated how you could use a LimeSDR Mini v1 with the Osmocom Cellular Network Infrastructure stack to create a low-cost GSM network. In this latest video we demonstrate a LimeSDR Mini v2 being used with the open source srsRAN software to create a private 4G mobile network complete with network core.
The demo utilizes Ofcom shared-access spectrum — similar to CBRS spectrum in the US — which is available for anyone in the UK to license for a low annual cost. The demo achieved up to 14 Mbit/s download speed and more than 2 Mbit/s upload using mostly default parameters and with no fine tuning. For further details please see the video below.
