  • Radio spectrum: exceptional social, cultural and economic value Opportunities for new electronic communications services: Wireless broadband communications Additional terrestrial broadcasting services Mobile multimedia services while safeguarding broadcasting and other services of public interest. Enabler for economic growth and competitiveness Supporting social inclusion and media pluralism Spectrum is part of Ireland’s national infrastructure. A limited asset and resource – we must use it wisely. Duty of ComReg and Government to manage this valuable asset. RTÉ happy to continue to play its part – Much is being said about using UHF spectrum ‘ white spaces’ (interleaving) for innovative wireless communications purposes – RTÉ supports these initiatives on the firm understanding that the regulatory authorities will undertake to safeguard the needs of public service broadcasting and other services of public interest. Spectrum is part of Ireland’s national infrastructure. It is a limited asset and resource – we must use it wisely.
