Digital Broadcasters Vendor News has been advised by the Australian Communications and Media Authority that the frequency spectrum in the 518-520 MHz band has been blocked and reserved for the re-planning of UHF Channel 27, to be allocated 520-526 MHz.
The move is to bring Channel 27 in line with all other channels to have a 7 MHz bandwidth, currently it only has 6 MHz.
The frequency range 518-520 MHz is currently used for the land mobile service (two frequency, 25 kHz channelling) and for the land mobile and fixed services (single frequency, 25 kHz channelling).
Expressed another way, Channel 27 is immediately adjacent to land mobile services below 520 MHz and to UHF television channel 28 above 526 MHz.
Channel 28 currently carries SBS-TV analog television in many areas.
The ACMA has informed Digital Broadcasters Vendor News that on present indications, channel 27 is unlikely to be available for mobile television for several years. Nor can ACMA rule out other applications for the channel emerging in the interim.
