Anyone come across a mobile phone that can also be used as an RT?  Just going through a project of refurbishing a 20 floor office building and need to provide Building Ops guys with comms device that will work on all floors and all the basement floors.  No mobile service on most of the basement floors so thought a combined mobile/RT device would be best.  Someone seems to think they've come across these, but I can't find them when I'm searching so thought I'd ask the very knowledgeable people on here Smile

Someone might be thinking of Push To Talk. :   )

Seen this service used a lot in the US, and have seen it promoted on some GSM networks in Europe.
But don't believe there was ever a good enough business case for it to be enabled on GSM networks here.

The Push to Talk (over cellular) service is meeting a different need. These are ideal for companies that need to dispatch staff to jobs, so they need to be able to call many staff at the same time, rather than call each one to see if they are free and staff can quickly respond without entering a phone number. Push to Talk over cellular means using existing cellular infrastructure rather than specialised RT repeaters or Trunked Radio networks.

It would appear that the topic starter is wanting to overcome coverage problems on a building site and Push to Talk over cellular isn't going to help there. Some sort of handheld VHF/UHF RT using simplex channels (direct) would be needed and I haven't seen these combined with a mobile phone.

Thanks people, very helpful.  I'll look at the Push to Talk option just in case it will help, but as you suspect the lack of coverage may be more of an issue and we're just looking into that at the moment.

Appreciate the help guys! Smile

That pricespy page is not right. Some "Push-to-talk" devices there don't actually have PTT. And is said before the service requires cell coverage. And IIRC both Telecom and Vodafone have discontinued the PTT service.

What BAChick needs is something like the Kordia KorKor.
