PTT on mobiles

[AJI]

Why does the PTT function of my different mobile phones over the years never work?
None of my firends can get their's working either.



(p.s. which sub-section of which sub-forum of which sub-topic will thread be moved into?)

It will be moved to electronics forum !

The reason it wont work is that non of the UK Network operators support PTT in the UK.

Goto Europe and you can use it, providing you buy a SIM over there.

ah cheers.

So its a setting on the SIM that prevents it working in the UK?
or is it an agreed setting by the UK network operators that they do not allow it?

ie. if I were to buy a SIM in europe, would it work in the UK?

just as an added question : how does the PTT work?
Is it like a radio walki-talkie...or is it lilke making a normal phone call on the operators network?

Cheers.

I doubt it would work in the UK; it requires some network infrastructure, which is not present in the UK.

I don't know an awful lot about PTT to mobiles to be honest, other than Orange did try to support it but it never took off. It was based on GPRS and was expensive.

I believe some police forces use it as backup.

thanks for that.

£17.00 per month... so I guess its not just a simple radio walkie talkie type of communication. Must be using the normal voice call type platform.

I was thinking it would be very useful if it were a walkie talkie type of set up that could reach out to other mobiles within range of an in-built radio transmitter, or even enhanced range with if it worked through the use of boosters in the mobile phone masts you see everywhere.

What you describe is very similar to the functionality of the police Airwave system (which is TDMA if I remember correcly), PTT via a network or as an old style walkie talkie in addition to normal phone style functionality. The problem with the walkie talkie arrangement is obviously very limited range and poor security. I can't imagine why anyone would prefer PTT to two way calling in normal situations.....

I was just thinking along the lines of using mobile phones instead of using walkie talkies basically. Able to communicate with work colleagues on a different office floor or from office to car park etc. without having to make an actual phone call.
I was thinking PTT was a free service that used radio, but I probably have got it completely wrong.

I stand to be corrected, but even if UK networks did support PTT, the signal would still go through a base station. i.e. one handset wouldn't be communicating directly with another handset, so you'd still need network coverage for both handsets.

If it just used radio the range would be awful, especially indoors, additionally the spectrum would be very limited so you'd be able to hear everyone's transmissions. The only way to practically do it would be through the network, I'm no telecom engineeer so don't know what effect this would have with carrier usage, call setup times etc on the base stations... might even be positive for them!
