ARLA/CLUSTER: Ofcom propoe usar segmentos de amador em 5 GHz para ligações WiFi

[João Costa > CT1FBF]

Ofcom propose using Ham Radio band for Wi-Fi

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, 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.

Ofcom's proposal to use 5725-5850 MHz for Wi-Fi would adversely affect
reception of the network of amateur weak-signal propagation beacons, see

The 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.
