Bristol-based network operator EE and its owner BT have teamed up with Lime Microsystems to create a competition for small companies and researchers to develop next generation applications for wireless networks.

The competition will run throughout June, July and August, finishing with a three-day Hackathon weekend in London from the 1 September. This will bring developers together to create compelling prototypes and demonstrations using the latest open-source, software-defined radio (SDR) systems developed by Lime. BT will support remotely developers who cannot make it to London.

Developers will be using open source LimeSDR boards which was launched last year that allows cellular, Internet of Things (IoT) and other networking standards to run on the platform as an app, significantly cutting the cost of roll out.

The competition is split into three categories:
1. Best implementation of an existing feature/solution
2. Best application of LimeSDR development kits to solve an existing problem
3. Most imaginative and effective use of the programmable features of the LimeSDR

For category 2, the scenarios include Disaster Recovery and Remote Connectivity for the “Last Mile” as well as Indoor Enhancements for wireless.

BT and EE will enable remote participation for those not based in the UK or who cannot travel to London. BT will also fast track at least one finalist from each category through the Facebook TIP Ecosystem Acceleration Centre.

There will be multiple entry deadlines, the first of which closes on the 9 June 2017 for those who already have an application in mind.

LimeSDR has been followed up by LimeNET, a series of IoT small cell and base stations for wide area networks, which is being crowdfunded until July 14 2017 .
