FleetCall’s name was derived from the 800 MHz designated by the FCC for use in fleet dispatching services. FleetCall changed its name to Nextel Communications in 1993. Interestingly, the technology had been around and in use as early as 1987, known as FleetCall. “The service also provides consumers with an ideal way to keep in touch with friends and family by making it easy to instantly communicate with each other as a group at the touch of a button.”īut John Delaney, at UK-based analysts Ovum, says it will depend on whether users are willing to pay for the extra functionality offered by Talk Now. Sprint Nextel officially shut down their iDEN network on June 30, 2013. Zellos Push-to-Talk Solution Helps First Responders in Urgent Situations. “Talk Now provides the business community with an immediate and reliable way to better manage teams of people,” said CEO of the Orange Group Sol Trujillo. zTrip switches from old Nextel phones to Zello and transforms the service. But such services can take time to boot up and are more prone to disruption because the internet is far bigger and less reliable than Nextel’s private network. PTT calls can also be made via the internet from enabled phones, using the net’s standard IP packet switching technology. Use-cases include airports, public safety, manufacturing plants, warehouses, mining and construction sites, hotel and hospitality venues, restaurants/retail and assisted-living centers. ![]() This is likely to make the service more costly more to operate. Push-to-talk (PTT) is a proven communications technology that is considered to be ‘mission-critical’ in many environments. This uses circuit switching to route calls, meaning each call opens a new dedicated channel which remains open until the call ends. In contrast, Orange’s Talk Now service will operate on top of the European GSM network. This, plus the fact that PTT was designed into Nextel’s network from the start, makes it cheap to transmit the relatively low quality PTT calls. This is efficient because only relevant data – i.e. Its network uses packet switching to route calls, meaning voice data from the caller is chopped up into packets, sent, and then reassembled at the recipient’s end. The most popular PTT service in the US is provided by Nextel. ![]()
