5 GHz – RSGB respond to Ofcom

The RSGB has published its response to the Ofcom statement on increasing the amount of the 5 GHz band that can be used for WiFi. The Amateur Satellite Service has a Space-to-Earth allocation at 5830-5850 MHz.

Annex 6 of the Ofcom 5 GHz statement says regarding Fixed Satellite Service (FSS) operation in 5725-5850 MHz:

“…once it becomes clear that this band will become used for Wi-Fi worldwide it will become less attractive for new satellites.”

“In Table 2 below we show the impact that different regulatory regimes for Wi-Fi might have on the exceedance of the protection criteria of the most sensitive satellites in 5.8 GHz assuming a comprehensive Wi-Fi roll-out across Europe and Africa.”

“As discussed previously, the risk of interference is an aggregate of all Wi-Fi use and so will rise slowly over a number of years rather than appearing suddenly.”

“The UK cannot cause interference to 5.8 GHz satellites on its own but it is fairly likely that Europe and Africa will follow our lead. This is likely to be driven by the potential for 5.8 GHz to become a worldwide Wi-Fi 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…”

Ofcom is consulting on plans to put Wi-Fi across Amateur and Amateur Satellite spectrum in the 5 GHz band.

The Ofcom consultation document implies that amateur satellites in 5 GHz only operate in very Low Earth Orbits – This is false.

A5.28 Amateurs can access 5650-5850 MHz with amateur satellite Earth-to-space links in 5650-5670 MHz and space-to-Earth links in 5830-5850 MHz. Most current amateur satellites are typically nano or picosats (also called ‘cubesats’) that occupy slightly elliptical sun-synchronous low earth orbits at 60-800 km altitude. These smaller satellites have relatively low power and antenna gain.

Radio amateurs have sent 5 GHz payloads into far higher orbits. Examples are the Venus orbiter Unitec-1 which operated on 5.840 MHz and AO-40 which is in a 58,836 km High Earth Orbit (HEO). The 5 GHz band will also be used by the Geosynchronous Phase-4B payload and the HEO Phase-3E satellite both of which are currently under construction.

The use of 5725-5850 MHz for Wi-Fi would adversely affect reception of the network of amateur weak-signal propagation beacons.

Ofcom-logo-col-tThe Ofcom press release says:

As broadband delivered to the home gets faster, people increasingly expect their Wi-Fi to provide several services at once – such as video streaming, video calls, gaming and remote working. This demand puts pressure on the spectrum which carries Wi-Fi signals.

Most Wi-Fi routers in the UK currently use a part of the spectrum called the 2.4 GHz band, but this is becoming increasingly congested and can impair broadband delivery of high data rate applications such as streaming video or live TV.

Many people now have newer broadband routers, which use not only the 2.4 GHz band, but also the 5 GHz band – which offers much more spectrum and can accommodate wide channels suitable for high data rate uses.

To make connections faster, Ofcom is proposing to open up an additional ‘sub-band’ within the 5 GHz frequency range for Wi-Fi – while ensuring protection for other users, such as satellite services.

The extra sub-band would increase the number of 80 MHz channels available for Wi-Fi from four to six, to accommodate data-hungry applications. These extra channels – which are already being used in the United States – could be opened up in around two to three years.

The consultation closes on July 22, 2016.

The UK Microwave Group (UKuG) point out that Ofcom’s plans for 5725-5850 MHz would unilaterally raise the noise floor for little benefit to consumers. They say 5760 terrestrial & EME and 5840 satellite reception need maximum protection. A Word Doc response form is available on the UKuG site at http://www.microwavers.org/

Ofcom clarifies position on SES call signs

Ofcom-logo-col-tOfcom had said NO to Special Event Station (GB) callsigns being used in the bands above 440 MHz for Amateur Satellite or Terrestrial operation.

The RSGB intervened and Ofcom have now issued revised clarification – Operation above 440 MHz with SES (GB) calls is permitted, so is operation in the 5 MHz segments.

It appears the SES call sign application form OfW287 is rather old and doesn’t list all the available bands. Fortunately that doesn’t matter since the NoV issued for the SES call sign is not band specific.

Well done RSGB !

UK Spectrum Strategy

RSGB Amateur Radio SlideOn June 30, 2015, Graham Murchie, G4FSG, RSGB Chairman and Murray Niman, G6JYB, Chairman of the RSGB Spectrum Forum presented the case for amateur radio to the UK Spectrum Policy Forum (UKSPF). The Amateur-Satellite Service featured in this presentation.

The Forum has been established as a sounding board to UK Government and Ofcom on future approaches on spectrum with a view to maximising the social and economic value from the spectrum.

The UK Prime Minister David Cameron has stated the ambition to double “the economic benefits of spectrum to UK companies and consumers from roughly £50 billion today, to £100 billion in 2025″.

The UK Spectrum Policy Forum, open to all users of spectrum, is the main vehicle for harnessing user insights and informing these policy decisions.

Ofcom considers 10.475 GHz and 47 GHz bands for 5G

Ofcom-logo-col-tThe Amateur Satellite Service allocations at 10.475 GHz  and 47.0 GHz are being considered by Ofcom for 5G use .

Ofcom has published an update on spectrum bands above 6 GHz that might be suitable for next generation mobile, often referred to as ‘5G’ – the fifth generation of mobile services.

This document summarises responses from Ofcom’s earlier Call for Input in January and sets out their current views on bands and next steps. The update identifies several bands in different parts of the 6 – 100 GHz range, including 10.475-10.575 GHz and 47.000-47.200 GHz, they believe are candidates for further study for use in the UK.

Ofcom’s goal is to have globally harmonised bands for next generation mobile services and is currently engaging with other administrations around the world, ahead of these services becoming commercially available in the next five to six years.

Consideration of these bands will now be taken forward in forthcoming international discussions, including the World Radiocommunication Conference-15 (WRC-15) at which the scope of a future WRC-19 agenda item on bands above 6 GHz will be considered.

This does not guarantee these bands will be adopted in the future and Ofcom do not rule out considering other options ahead of WRC-15, pending further research and development.
