1.17 Airwave will solve the existing problems with radio communications, but will cost more than double the current spending on existing systems. Many forces have been under-providing for their communications systems for several years, partly in anticipation of Airwave, which may account in part for this disparity. Airwave will also cost significantly more than a series of separate replacement systems procured by individual forces, although some of the key functions offered by a national system would not be provided by local procurements. PITO considers that any modern radio system would be relatively costly, but that Airwave should deliver additional benefits that justify the additional costs.
