5GHz WiFi - Birkrigg

Took an Ubiquiti Nanobeam M5 up Birkrigg Common on Saturday to see what I could get on the 5GHz WiFi band.
Click the pictures of the site surveys to enlarge. Anything above channel 5.65GHz (channel 130) is also in the 5.7GHz amateur band, which is shared. See this white paper for how WiFi devices use the 5.1 - 5.8 Ghz band.



Those were site surveys with the dish pointing in different directions. I guess the DE ones are Dong Energy, who run the wind farms out at sea. There are a few with what looks like a Preston postcode in the SSID - and PR1 3RP is Sandown Court, a block of flats in Preston so it makes sense.

Belkin router working as the 2.4GHz access point, so I could connect to the Nanobeam's internal web app using my phone. Powering the Belkin off car battery.

 The Nanobeam uses 12 volt POE, not the standard 48V, so here I'm using a POE injector and an 11.1V LiPo battery pack, at the dish end of the cable to reduce losses. The pole is over a microphone stand.


After that I had a walk up Hampsfell (WOTA Outlying Fell LDO-108). Took the dualbandheld up there and made 3 QSOs, the furthest being GB6AC on 145MHz, a special event station operating from Abergele Castle in north Wales.


There are steps to the top of the little tower, which gives a little bit more height for the radio.


And here is some of the Wigle WiFi scan from the top of Hampsfell on my phone. As usual there are some caravan sites, but somebody's Talk Talk home WiFi is coming through, possibly from down the hill in Grange. Somebody is also Pretty Fly for a WiFi - there's one in every town!

Interesting post and nice pics to accompany! What was the point behind this? Just to see what you can pull in or is there another use behind it? Thanks for sharing.
