Ofcom has today published data from tests examining co-existence between wireless microphones and other equipment used in Programme Making and Special Events (PMSE) and White Space Devices (WSDs).
This data will help Ofcom design rules for future operation of WSDs to help prevent harmful interference with PMSE equipment.
Ofcom is currently piloting a new type of technology called dynamic spectrum access. Use of dynamic spectrum access technology could allow WSDs to use the same spectrum as PMSE and digital terrestrial television, but at frequencies, locations and times which mean that existing users would not be adversely affected.
The testing described in this report include tests conducted in controlled laboratory conditions, in theatres during live performances where many wireless microphones were used and during a live outside broadcast event. These tests are one part of this pilot, which also include:
- similar tests in relation to the potential of interference from WSDs into TV reception via Freeview;
- tests of processes, software and databases required to make the technology work; and
- trials of services using WSDs.
Ofcom currently expects to publish a statement in early 2015, setting out plans for implementing the use of White Space Devices in the UHF TV band. This will also draw on the evidence collected in our on-going TV white space trials and other relevant evidence provided to us by industry.
