U.S. Carriers Looking To Connect Push-To-Talk

U.S. carriers are looking at Push-To-Talk (PTT) as a way to generate more revenue from younger consumers, who seem to enjoy using the service. Push-To-Talk essentially allows a mobile phone to function like a walkie-talkie, and carriers are looking at ways to increase initiation speed, as well as allow interoperability between networks.

MetroPCS recently launched its version of PTT, which allows users to connect with friends and family on other networks. The service requires a specific handset, but allows the user to start a PTT conversation with any other cellphone, temporarily allowing the recipient to use their handset as a walkie-talkie.

Verizon Wireless, another U.S.-based carrier, is also working to increase the speed of the connection for its PTT service, hoping to make the connection even more instantaneous.

Historically in the U.S., PTT was used mostly by construction workers and field representatives on Nextel's iDEN network, which was designed for the service. Since Sprint purchased Nextel, it has increase the number of subscribers, and updated the quality of the PTT service, as well.
