Mr. Robert Morton:

From a NAS perspective, a text message is received. Some will have TETRA radios, but the majority will get a text message. They are geofenced, effectively, on our CAD system. The community first responders, CFRs, are geofenced into a particular geographical area. What the CAD system does is to hunt for every single resource in that area and alert every available resource in that area. If a CFR has declared themselves available, they will get a message saying there is an incident at that location and asking can they mobilise.
