An end to tinny calls – High-definition voice calls and tested over 4g




Between let’s say 1995 and 2012 happened a lot in the telecom industry: where time many people have mobile phones considered obsolete, everyone quickly went to a cell phone. Sms came over and touched its peak, mobile internet via 3g and 4g came on was already live in parts of the world.

But what did not change was the basis of mobile telephony: call. That sounded and sounds like you’re still mostly connecting two empty cans of pea soup with a piece of string to each other and talk. That’s nice as an experiment for kids, but in times when many people are using Skype or other VoIP, thereby hear better sound quality, but hopelessly outdated. Unlike the pea soup cans it takes to call you long before you get someone on the phone.

In Tweakers we do not pay much attention to the call quality of phone: there is often little difference between and moreover many readers hardly interested, because the app with the green horn is one of the least used applications on their phone.

But occasionally there comes a technology through which we focus our ears and do again paying attention to mobile calls. In this story, we test two such technologies: adaptive multi-rate wideband and voice over long term evolution. You may know it better as HD voice and call on 4g. Because we got the chance to try both technologies we decided a backstory to hang clothes. You get with these two technologies finally call quality that you would expect in the year 2014?
