AT&T Rolls Out Push to Talk

Posted by Sam Churchill on

AT&T’s new Push to Talk (PTT) service can run on its LTE network. AT&T said its Enhanced PTT service will cost $5 per month when added to existing AT&T voice and data plans or $30 per month for a PTT-only rate plan (no voice or non-PTT data included).

Both plans include unlimited PTT, and data used by the Enhanced PTT application will not count against a customer’s monthly data totals.

The Enhanced PTT application can be downloaded from Google Play, and will be preinstalled on the Samsung Galaxy Rugby Pro, the Samsung Rugby III, the BlackBerry Bold 9900 and the BlackBerry Curve 9360. Customers can also download AT&T’s PTT application and install it in the Samsung Galaxy S III or Samsung Galaxy S II Skyrocket.

AT&T’s Enhanced PTT is based on technology from Kodiak Networks. AT&T says it has sub-second call setup; larger contact lists and talk groups than rival PTT solutions; can combine PTT services and mobile applications; supervisory override; and talk group scanning.

Sprint is actively working to recapture iDEN customers onto its CDMA network, notes Fierce Wireless. Sprint has around 3 million customers on its iDEN network. The carrier hopes to move its iDEN customers to CDMA and LTE PTT service, then decommission iDEN next year. Sprint said in September that 1 million subscribers are now on Sprint’s CDMA PTT service.

Qualcomm’s QChat is Sprint’s PTT solution for improved coverage running on EV-DO Rev. A. Sprint Nextel also offers a downloadable application from Google Play that enables subscribers to leverage push-to-talk capabilities on Android smartphones like the Kyocera Rise and LG Optimus Elite

Sprint’s new CDMA Direct Connect PTT service offers similar PTT speeds as its iDEN network with greater coverage.

Sprint’s Push-to-talk coverage footprint is planned to increase to nearly 2.7 million square miles and is expected to cover a population of 309 million – an increase from the iDEN network’s 908,370 square miles covering a population 278 million.

Sprint is using CDMA, not LTE for their push to talk.

Sprint is refarming their 850 MHz iDEN network with CDMA, to provide better coverage (along with 1xRTT data) for customers. iDEN was not able to provide the data connection and did not merge well with Sprint’s Network Vision.

In the third quarter Sprint says it was able to recapture 59 percent of leaving postpaid Nextel customers and move them to its CDMA network, just below the recapture rate of 60 percent in the second quarter.

Sprint Nextel will add capacity to its LTE network from its 1.9 GHz (PCS) band that the carrier uses for most of its voice and data traffic. Sprint plans to move voice traffic to the 800 MHz band and data traffic from CDMA to LTE. Sprint Nextel has between 20 megahertz and 30 megahertz of spectrum in the 1.9 GHz band outside of its current G-Block (2 x 5MHz) LTE spectrum.
