Ericsson places first HD call over CDMA

Take a look at the best smartphones on the market – they are shiny, powerful, and versatile. Ten years ago they would have looked like something out of a sci-fi movie, right? So why is it that we have not seen that much of an improvement when it comes to the quality of our phone calls? Well, reducing the call's sound quality is saving carriers precious bandwidth, but advances in technology may finally allow us to experience higher fidelity calls sooner than we may imagine.


Ericsson is the company that has been investing time and resources in hope to bring a “voice quality revolution” to the cellphone industry. The telecommunications giant has just announced that under laboratory conditions it has successfully placed "HD phone calls" over CDMA connectivity. As the name implies, these are voice calls of much higher quality than what we are used to today. The leap in quality was achieved by expanding the audio spectrum, which the phone call occupies, resulting in higher fidelity sound reproduction.


High quality calls have actually been demonstrated for the first time by Ericsson at MWC last year, but instead of using CDMA connectivity, the technology was demoed on an HSPA network. Ericsson has not announced whether it will be deploying their technology anytime soon, but chances are it may need more polishing if real world results do not look promising enough.

I dont have a problem with Verizon's call quality at all. I never have static, white noise, no issues with background noise and no drop calls. I know it differs from location to location but I have no issues with calls. Most people don't even use their smartphones to call people anymore anyway. It's more about faster processors, gaming, web browsing, facebook, texting, etc etc.

The fuck is this?

I never use my phone for talking anymore. Maybe to call parents and from time to time friends but I literally only use like 50 minutes a month and that's on a very rare occasion I use that much. Talk about burning money for no reason sony :/

Why do people say they don't use phones to talk but scream to high heaven when AT&T drops calls? I'm not sure I understand network arguments anymore.
