6 Radio Spectrum for PPDR Communications

6.1 Spectrum Management: Regulatory Framework and Models

Spectrum management is the process of regulating the use of radio frequencies to promote efficient use and gain a net social benefit [1]. An efficient spectrum management has to address three main interrelated problems. First, the correct amount of spectrum needs to be allocated to certain uses or classes of uses. Second, it needs to assign usage rights to certain users or groups of users. Third, it needs to adjust established policies as technology and markets evolve over time.

The radio spectrum is considered in most countries as an exclusive property of the state (i.e. the radio spectrum is a national resource, much like water, land, gas and minerals). As such, there are different radio spectrum items that need to be nationally regulated (e.g. frequency allocation for various radio services, assignment of licence and radio frequencies to transmitting stations, type approval of equipment, fee collection, etc.). To this end, national regulatory authorities (NRAs) are commonly established within sovereign countries as the competent legal regulatory bodies for spectrum management and regulation. However, due to the very nature of radio spectrum (radio waves do not respect administrative borders), international agreements for regulating the use of radio frequencies are necessary to, among others, coordinate wireless communications with neighbours and other administrations. ...
