AT&T's Enhanced PTT Targeting November Launch
AT&T is preparing to kick off the availability of its improved push-to-talk service in November, according to company web sites. Previously, AT&T only said it would launch the new service by the end of 2012. AT&T spokesperson Mari Melguizo said in an email to Fierce Wireless, "Using AT&T's IP data network as the backbone for the solution we're trialing will provide faster connection times and better quality of service. Kodiak's InstaPoC technology is an advanced PTT service that achieves sub-second call setup times without requiring customization on radio access networks (RANs) or underlying cellular networks." When it launches, AT&T's improved PTT service will support a handful of smartphones, including the Samsung Galaxy S III.
