Fire and EMS operations will be on UHF conventional. The UHF trunked system will support other purposes and users. The system was delivered is being installed. There are 10 TX simulcast sites and an additional constellation of RX sites.
I do not know how the schedule will pan out. However, my educated guess is that the system will be online well before the end of the year and then the new system and the old system will be cross-patched. During that cross-patched period I would expect that the FDNY will perform the changeover of radios in the trucks and ambulances.
What is happening now? While Motorola is installing the system, the FDNY radio technicians are being trained on the system. As well, we hear some system testing.
