Radio Antenna on street lights

There are some programs that can determine wifi signal strengths you might find useful:

One I have used is INSSIDER

Also wifi analyser on Android phones. Very comprehensive data.

Complain, then. RF polution from poor designed devices is becoming a major problem. I don't know for sure what the idea is behind this, but I am aware that there is a new methodology for detecting street lights that are about to fail by examining their RF profiles with a spectrum analyser. Antennas on the posts enable the people monitoring the lights to do so from further away; therefore more quickly and cheaply than having to drive directly to each and every one of them.

Have you tried changing your Wifi channel?

For some WiFi signals. It doesn't show point to point WiFi based links, Bluetooth, various video senders, leaky microwave ovens and all manner of other kit that uses that bit of spectrum.

Such things have a use but be aware you don't see the whole picture. There might be software for PC's that do give a proper spectrum analayser display, that is the actaul RF level over band of frequencies.

Have we come back to last Christmas. I though this was solved? Brian

inkeysdownham seems to have a new problem...

Complain to whom exactly?. 2.4 Ghz is a free for all these days and thats just "tough"..

You might try 5.8 Ghz theres more room up there if your equipment is equipped for that band.....

Nope, the people who designed and built that system know exactly what there're doing!. There're a spin off of this one who if you look at their client list you'll see there very highly regarded:)..

They use very ultra narrowband techniques for that a bit of which I think is patented..

I'd like to see a spectrum analysis of the complete lamp/wireless assembly. The word "dimmable" on a discharge lamp does not inspire confidence.

I thought his name was inspired by Sinclair Basic, but it turns out that he does pokes of an entirely different kind.

istumbler for mac.

I thought they were meant to go over to those LEDs that project more light down rather than up.

I doubt that anything EMC related would be missed by the above firms involved in that. They have some -very- comprehensive testing facilities:)...

Well they are mindful of light pollution these days. However our local council have reduced the overall light in our street by not replacing one lamppost when they "upgraded" them;(...
