My clock radio has been making some noises a lot recently, mostly like the noise you hear from speakers when there is an incoming call or message on a nearby mobile phone, but in almost every case there has not apparently been an incoming call or message. Could someone be unsuccessfully trying to get through or is it just the government listening in on me?

Definately the government.

Get yourself a foil hat now and protect yourself before it's to late.

This is usually just a signal being sent and received between your phone and the closest tower. My house sucks when it comes to that noise because we have coverage from two towers and it is always switching between the two.

It's definitely the government.
You'll be wanting to pick up some extra rolls of tin foil on the next grocery shop there.


Either that, or the phone is just doing it's general "handshake" thing with the nearest mobile tower.

But I'd be going with the government option.

Why would the government be listening to you? Do you really think you are that important?

Maybe the poeple in the nondescript black van are just bored, and want to listen to your clock radio, just let them be!

Behind the scenes 'handshake' as Mosh pointed out.

For the system to work efficiently your phone and the towers need to know your location in the network. It is an incredible waste of resources to send a call request to every tower in the country in order to reach your phone. A better option is for the system to know which tower you are on and to send the call request there. As you move around, this needs to be constantly updated. Same goes with the internet. When you request Google, only Google receives the request rather than every person connected to the internet.

There are also issues with frequency and time slot allocation as two adjacent towers will have different frequency bands so that they do not interfere. Keeping this information up to date ensures that you are not transmitting updates on the same frequency/time slot as another phone.

I believe GSM also has a limit of ~35km max due to the timing issue, but as there are also a limited number of channels available on each tower so to allow more people on, tower ranges are limited and placed closer together. It also helps to not give each person a constant dedicated call channel rather they use a control channel to setup the call so that only users in a phone call actually use up an entire call channel. This is also used with landlines. 100 users may have lines to the exchange but only say 10% will call at any one time so the switch will have the capacity for 15 or so calls to be switched at any one time. Setting up that channel is why your phone makes a whole heap of noise before it starts to ring.

I hope I remembered all that right from tellecomms in first year uni.

Tin foil hey? Thanks for the tip. Should I use it for wallpaper perhaps?

I wasn't serious...

Anyway, it wasn't like that before and now I think it stopped again. Anyone know why this would be?

Thanks.

I reckon this... I get that sound quite often and its just the signal changing.

Actually with 3G it's which towers you are connected to, this is the main difference.

2G connect to 1 tower at once.

3G connect to multiple towers at once and splits everything up between them.

This is how the high data speeds are achieved.

They found this thread and know that you know.

Watch out, they could be listening to you through your TV next.

They watch through the TV and microwave, they can only hear your thoughts through the radio.
