The pilot will test the inter-operation of white spaces devices, white space databases and the processes to mitigate against causing any undue interference to current spectrum users.
Another issue for current air traffic control systems is that they face interference from wind farms, which are increasingly springing up around the UK to provide alternative sources of energy.
Unlike earlier solutions -- like Eugene Polley's "Flashmatic" remote -- Robert's remote wasn't prone to interference, didn't require a wire, and, unlike current remotes, didn't require a power source.
