Once the realm of contractors on the Nextel network, push to talk (PTT) will be spreading to other networks by software that uses always on data connections to turn you handset into a very advanced walkie talkie. The first method to enable this feature are applications that run on smartphones, including the Windows Mobile platform.
The Economist (of all magazines) looks at the state of PTT in the US. It looks like ATT and Verizon are both seriously working on adding this to their networks. The Economist even wonders if PTT might be to America what SMS is to the rest of the world- a way to cheaply communicate a short message (nearly) instantly.
This is an interesting metaphor, especially in light of Boost mobile. A subsidiary of Nextel meant to sell nextel handsets to the youth market, Boost calls PTT "2-waying." However anyone who knows what kids
actually mean when they say "2-way" is to text message, as in 2-way pager.
Textually points out that corporate executives aren't interested in using PTT. Normally i'd hop on my soapbox and point out that what corporate executives want from a mobile phone rarely turns out to be what the mass market wants, since the market is defined by 18-25 year olds. However I can pretty much assure you that Boost is failing with the kids, despite having some of the most hilarious TV ads ever. Their service is too expensive, and none of their friends have Boost, so why would kids want it when all they could do is 2-way themselves?
PTT might have a better chance of succeeding as a premium data service on a network that already has a high youth penetration. Or a network with Smartphones like Orange or someone might be able to add it as an extra selling point. Would you use it?
