Ofcom plans to free up more 5 GHz spectrum for WiFi deployment

According to foreign media reports, the UK telecommunications regulator, Ofcom, is seeking opinions on extending WiFi access to an additional 125 MHz of spectrum in the 5.8 GHz band.

As always, the consultation process involves publishing draft regulations, which anyone can comment on. Typically, this means that companies with commercial interests will debate with those without commercial interests after Ofcom has made its recommendations - although Ofcom's decision is usually made long before the consultation begins.

The May 2016 consultation on the 5 GHz band identified the following aspects:

• Short term: Opening the 5725-5850 MHz spectrum for WiFi;
• Medium term: Review technical requirements for WiFi (such as those designed to protect radar) to ensure they are suitable for planning purposes and not unnecessarily restrictive;
• Medium term: Promote the use of WiFi within the existing primary mobile allocation in the 5850-5925 MHz band;
• Long term: Remove outdoor restrictions on WiFi access in the 5150-5350 MHz range;
• Long term: Open up spectrum in 5350-5470 MHz.

After a consultation, the Communications Administration decided to proceed with Plan A, the short-term plan, citing the increased consumer demand for Wi-Fi as a driving factor. The regulator's consultation did not cover other aspects, but the final approval of this proposal is almost certain.

As it relates to WiFi, this spectrum will not require a license, but the legislation related to it will need to be amended - which does not require European approval. Stakeholders will begin to present their opinions and suggestions on April 11.
