Verizon Wireless Testing IMS for Voice Over LTE

Feb 18, 2010, 11:53 AM by Philip Berne

Verizon Wireless, a former interloper at the GSM Association’s Mobile World Congress in Barcelona, has announced that it has installed IP Multimedia Subsystem (IMS) technology that it will use on its upcoming LTE network, according to Fierce Wireless. Unlike existing networks, LTE will not have a separate voice component, so compatibility between the various networks’ methods for sending calls over the future network technology had been a concern. To support the IMS technology, which is growing in popularity among LTE operators, Verizon Wireless is currently testing the tech on its existing 3G network. This is in addition to Verizon Wireless plans to allow Skype calling over its data networks in the near future. Of note, Verizon Wireless has also made clear that its CDMA 1xRTT network will still support voice traffic for at least another 10 years.

T-Mobile recently announced that its mid-band 5G network now covers over 200 million people, a threshold that the industry acknowledges as "nationwide" coverage.

WoW!!! 10 more years of CDMA!

WoW, 10 more years of CDMA. So in the year 2020/2021 Vzn will still be using a tech that isn't the world standard.

Megatron

Then go to AT&T or Terrible Mobile. I'm sure you will love the coverEDGE. the fastest 3G! 😁

2G CDMA is still the most efficient way to handle voice traffic. There is absolutely no incentive technologically or financially to shut down the 2G network.

Why WOULD a company rip out a technology that is working just fine and replace it with ...

thinks its funny all 3g is CDMA

lol 3g is CDMA guys, AT&t and Tmobile use WCDMA and there is very little difference between WCDMA and the EVDO IS-95 use by Verizon and Sprint. You are both comparing the tech used to make phone calls GSM vs CDMA 1x (sometimes called IS-95) The reason why you see such a big difference in coverage is its was much easier for IS-95 carriers to upgrade their existing voice network to add data than is for GSM carriers to install a whole new WCDMA network

so on Verizons network the same channel on a tower can be a voice or data call, with AT&T or Tmobile they have separate towers for 3g and GSM voice

GSM

GSM will only cover so much data. If you take a look at the AT&T system you will see that they go from GSM over to a form of CDMA. This is because they have met the maxium speed for GSM (EDGE) with data. They had to create a "new" form of a network to get faster speeds with the net.

Megatron

And isn't AT&T having data issues? Weren't they going to bribe customers NOT to use their internet because their super-sweet iphone was using way too much bandwith! I think you are right...GSM,the world standard, is the best choice and all companies s...
