Azetti PTT system has taken off very well in chilean market, which Walky Talky needs were covered previously by iDEN technology, as Nextel was operating on the market. Nextel got 4G license and has been covering mobile network coverage thru own infrastructure as well with roaming agreement with Claro Chile. Later Nextel was sold to european investors and changed it`s name to WOM. Modern PTT systems use just data from mobile networks, but can also operate via WiFi and provide much wider service options to users; including large groups, location, instant messaging including images as well PC DIspatcher. Smartphones allow to run PTT and sectorial application in the same device, which makes the combination irrestible to end users with huge advantages and benefits.
