AT&T to launch VoLTE on May 23rd

US operator AT&T has announced plans to launch Voice over LTE services next week, on May 23^rd. Simultaneously the firm will introduce HD Voice services, which looks likely to be the centre of AT&T’s VoLTE related marketing campaign. In a brief release issued Thursday, the firm said it was introducing HD voice on VoLTE, promising customers that they would no longer “have to choose between faster data speeds and crystal clear conversations.”

The initial market will be limited, however. HD Voice will only be available to customers who have a Samsung S4 mini and are making or receiving calls in a limited footprint comprising “select areas” in Illinois, Indiana, Minnesota and Wisconsin. AT&T said more devices and an expanded coverage area would follow in due course.

Earlier this week Japan’s NTT DoCoMo revealed plans to launch VoLTE following a network software update scheduled for late June or early July this year.   DoCoMo said that users will be able to access LTE data throughputs of 150Mbps during voice calls as well as the firm’s disaster information notifications.

The 2^nd annual LTE Voice Summit is taking place on October 7^th-8^th 2014 at the Royal Garden Hotel, London. Click here NOW to download a brochure.
