Ofcom statement on 5725-5850 MHz

On Friday, July 24, Ofcom released their statement on 5725-5850 MHz and 5925-6425 MHz.

The main points are:
• Make 5925-6425 MHz available for Wi-Fi and other RLAN technologies
• The release of this spectrum will also enable very low power (VLP) outdoor use
• Remove the Dynamic Frequency Selection (DFS) requirements from channels used by Wi-Fi in the 5725-5850 MHz Amateur and Amateur Satellite Service allocation

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 could obliterate the weak amateur satellite signals.

Wi-Fi Channels in the 5 GHz Band

Ofcom 5 GHz Consultation – RSGB and AMSAT-UK responses

Ofcom-logo-col-tIn their response to the Ofcom consultation on Wi-Fi in the 5 GHz Amateur Radio allocation the RSGB said “We are deeply disappointed in respect of Ofcom’s compliance with its duties…”

The Radio Society of Great Britain (RSGB) response highlighted that:
a) Ofcom has deliberately not contacted the most innovative incumbents/stakeholders as
stated in Para 3.43 (only Wi-Fi) prior to the formal consultation period
b) As an incumbent we have been blocked from contact during the consultation
c) Ofcom has ignored their duty with respect to CEPT ECA allocation footnotes ECA17/23
d) We expect Ofcom to makes amends and engage, or we will consider escalating this

The Society pointed out that “Ofcom’s research is badly flawed and belittles incumbents…” and “Ofcom strategy for Consumers is also flawed…”

The RSGB describes how “Ofcom’s preference risks causing harmful interference at home and internationally” and “Ofcom continues to unfairly suppress the most innovative stakeholder in the band, and undermine technology for innovation and emergency communications…”
