Radio Spectrum

Radio Spectrum

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 cellular phones, especially smartphones, tablets and other 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 other applications. Rather than developing new technologies, TCCA believes that use should be made of existing technologies and, for high speed data, LTE is an ideal transport mechanism.

Although some services may be provided by commercial cellular 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 that protect the critical national infrastructure such as the Utilities and Transport organisations. TCCA is working with other like-minded organisations to lobby Governments and Regulators to allocate suitable spectrum, particularly below 1GHz.

The World Radio Conference in 2015 resolved:

  • to encourage administrations to use harmonized frequency ranges for PPDR
  • to encourage administrations to consider parts of the frequency range 694-894 MHz
  • to further encourage administrations to also consider parts of the following regionally harmonized frequency ranges, for their PPDR applications: in Region 1: 380-470 MHz

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.
