Radio spectrum overview
All mobile communications technologies require spectrum in which to operate and this applies to TETRA and broadband technologies. However, spectrum is a scarce resource and the exponential growth of mobile devices is putting regulators under extreme pressure to find new spectrum for expanded services.
Critical communications users are also looking to make use of data-intensive applications. Examples include access to centralised databases, patient telemetry, high definition images and video streaming, telecontrol and many more. Rather than developing new technologies, TCCA believes that use should be made of existing technologies and, for high speed data, LTE and/or 5G are ideal transport mechanisms.
Although Mission Critical services may be provided by commercial mobile operators we believe that true Mission Critical operation needs to have spectrum that is set aside for Public Safety and Security, PPDR, and for those sectors that help to protect the critical national infrastructure, such as utilities and transport. TCCA is working with other like-minded organisations to lobby governments and regulators to allocate suitable spectrum, particularly below 1GHz.
North America is using Band 14 for broadband; Greater Europe has through the ECC narrowed it down to anywhere in 698-736 / 758-791 MHz. Asia is more looking to the 800 MHz band.

In greater Europe (48 countries) the ECC considers and develops policies, recommendations and decisions on electronic communications activities. More can be found here.
ECC operates an online database (EFIS) where member states keep track of their implementations.
