Ofcom Consultation: Improving spectrum access for Wi-Fi

5840 MHz UNITEC-1 Venus orbiter

5840 MHz UNITEC-1 Venus orbiter

Ofcom wishes to boost the use of Wi-Fi in Amateur Radio spectrum at 5725-5850 MHz.

The Amateur Satellite Service weak-signal downlink band, 5830-5850 MHz, is used by amateur payloads on Deep-Space and Interplanetary spacecraft as well as by satellites in Low Earth Orbit (LEO). Increased use of Wi-Fi across these frequencies would obliterate the weak amateur satellite signals.

Ofcom propose to remove the Dynamic Frequency Selection (DFS) requirements from Wi-Fi channels in 5725-5850 MHz. They also propose to make 5925-6425 MHz available for Wi-Fi.

The consultation closes on March 20, 2020.

Iceland’s national amateur radio society, the IRA, reports Elín Sigurðardóttir TF2EQ, launched TF3YOTA from TF3IRA’s radio room in Skeljanes on December 19.

First at 14 MHz and when the conditions disappeared it switched to the IRA’s satellite station for communication via the Es’hail-2 / Qatar-Oscar-100 satellite. Ari Þórólfur Jóhannesson TF1A, IRA VHF Manager, assisted Elina and posted, among other things, a fun video of the contacts on Facebook.

The YOTA project began last year (2018) and will be operational in December each year. It is designed to increase young people’s interest in amateur radio. The project is under the auspices of IARU Area 1 and all national amateur radio amateurs in the Region are involved (as well as national members of Regions 2 and 3).

Elín Sigurðardóttir TF2EQ, is the IRA’s youth representative and YOTA project manager together with Árni Frey Rúnarsson, TF8RN. They plan to activate the call sign on as many HF bands (as required) throughout the month, as well as contacts on the OSCAR-100 satellite.
