Putting aside that users can talk as a group, up to 5 people, what advantage is there in PTT? It does not appear to save cost per call, and if it is like a walkie talkie then as soon as you push the Talk button, the cost would begin even if the other person is not there to respond. Anyone using PTT ?	Strommer (42)

342277	2005-04-06 21:42:00	Anyone using PTT ?so what is PTT? at first i thought it was an RT extension of a cellphone, but now i' confused. :lol: :eek: Are there "channels" that groups share, and if so what stops someone from listening to YOUR PTT calls? Is it some kind of specialised cellphone call, and if so, at what price?	personthingy (1670)
342278	2005-04-06 22:54:00	But why not just use ordinary cell phone calling? Because you have to make multiple phone calls. The best example I have seen so far is the construction site example. You could either make up to 15 calls to find out who has the power drill at the moment. Or you could make one PTT which all 15 workers will receive. That is cheaper and quicker than the 15 cellphone calls. Of course a text message could be used as well I suppose, but again this will take a lot more time and cost a lot more.	Jeremy (1197)

Then when you work in the range,ease of use and life cycle of the unit.....then using a fiddly cell phone to do the job is just retarded. No construction company would ever arm their site workers with a personal cell phone each.	Metla (12)
342280	2005-04-06 23:41:00	Because you have to make multiple phone calls. Yes, of course - as stated in my starter post on this thread. So then PTT is for group calling, group messaging, with no advantage for non-group users??? When a person pushes / initiates a call, say to a group of other workers, does that person's voice come out of the other people's cellphones (without the phone ringing)? I would assume so, because this is like an RT / walkie talkie. BTW, I was in Sydney in January and PTT was in use, at 1c per second (at least on the plan I was looking at). Cheap if you just want to say "Meet me in the car park" - quicker than texting and much cheaper than the usual (pre-pay) phone call.	Strommer (42)

Long distance or national radio trunks are pretty costly, and the hardware is expensive.	ninja (1671)
342283	2005-04-07 03:08:00	Meh......National trunks? How big is this constuction site? Our handsets are good for 3 or so km,plenty big enough for any site.	Metla (12)
