Verizon's next-gen voice service still planned for this year, will come with video calling
Verizon and AT&T, the two largest mobile operators in the US, have spent the last couple years in a race to deploy next-generation voice technology known as Voice over LTE (VoLTE). With its announcement last week, AT&T was the first to deploy the fast-speed VoIP network, but don't count Verizon out of the race quite just yet: executives explained to us today that it's still on track for nationwide deployment sometime this year.
Orange introduces 'HD Voice' calls -- 3G, Moldovian citizenship required
You may not have realized it, but all of the cellphone calls you've been making have totally not been HD. While we may still be stuck with our old standard def calls for a while yet over here, it looks like the good citizens of Moldova have now finally vaulted into the future courtesy of Orange, which recently made the very first "HD Voice" call in the country (on 09/09/09, of course). Overused acronyms aside, the calls do indeed appear to be of noticeably better quality (at least if the web demo is any indication), which is mostly due to their use of the new Adaptive Multi Rate - Wide Band (or AMR-WB) codec that takes advantage of the greater bandwidth afforded by 3G. Unfortunately, it looks like the HD Voice-ready handset options are a bit limited to start with (just an Orange Moldova-exclusive version of the Nokia 6720), but it looks like more phones are expected to become available as Orange expands the service throughout Europe over the course of 2010.[Via GSM Arena, thanks Sathish]
