A couple of Tweets and a short web piece suggest Sweden may get HD voice service via VoLTE next year. But there’s not a lot of detail as to what carriers might be launching the service.
“Soon HD audio for mobile calls,” published in Computer Sweden, runs a brief quote from the sales manager from Huawei Sweden saying that “Nordic operators are at the forefront of [4G] technology and see it as an opportunity to differentiate themselves” – an interesting viewpoint considering South Korea is far ahead of the curve on deployment of LTE, VoLTE and advancements for VoLTE.
Huawei believes the first commercial launches of HD quality mobile calls will be in the second or third quarter of this year, but didn’t name names. Sweden tweets on the issue wouldn’t speculate other than saying “several vendors” used Huawei equipment. The October 1, 2012 Global mobile Suppliers Association (GSM) lists 3 (April 2012), Telenor and Tele2 (Joint network venture – November 2010) and TeliaSonera (December 2009) as having operational LTE networks.
There’s also some allusion to Huawei’s successful test with Qualcomm and T-Mobile Austria of VoLTE call continuity between LTE and HSPA-networks using the Enhanced Single Radio Voice Call Continuity (eSRVCC) specification. The October 12, 2012 lab tests used devices running Qualcomm’s Snapdragon S4 MSM 8960 chipset.
