Radio Spectrum Guide for Birmingham 2022 Commonwealth Games

/

Ofcom has published a guide with key advice for people who plan to operate radio equipment at the Birmingham 2022 Commonwealth Games

The reliability of wireless devices, from walkie-talkies used by event organisers to TV cameras broadcasting to a global audience, will be pivotal to the successful delivery of the Games, when the demand on the radio spectrum will be unprecedented.

Ofcom is responsible for protecting and managing the airwaves that are used for wireless communications. So, we have published a guide for people who require a license to use these devices at locations within or around Games venues.

Given the high demand for spectrum and limited availability of radio resources in these locations, we are encouraging early applications for licenses.

Proposal to Ban all 300-2000 MHz Transmissions in SZM

/

Proposal to ban all radio transmissions between 300 MHz and 2000 MHz in the area designated the Shielded Zone of the Moon (SZM), this would also be applicable to Mars

The spectrum would instead be used for radio astronomy operations, this would mean the Amateur Satellite Service allocations at 435 MHz and 1260 MHz would no longer be available to spacecraft in Lunar orbit such as Lunar-OSCAR 93 and Lunar-OSCAR 94 (Longjiang-1 and 2)

The frequencies of the spectral lines of astrophysical interest are:

  • 327.4 MHz hyperfine transitions of the deuterium atom

  • 1,420.4 MHz neutral hydrogen (HI) line

  • 1,612.2 MHz OH radical line

  • 1,665.4 MHz OH radical line

  • 1,667.4 MHz OH radical line

  • 1,720.5 MHz OH radical line
