CDMA to LTE Data Handover Completed..

While this may not be the biggest news for most of the community, the first live and active passover of a data connection between a CDMA and LTE (Long Term Evolution) device has been completed. This means that a device that has both a CDMA and LTE chipset, respectively, handled a data connection and switched over from one technology to another without a loss of the data connection.

This is significant for a few reasons. First off, this showcases future technology that Verizon Wireless may use when they start their own roll out of LTE. Also, having a device like this would allow for users to use LTE in Europe/Asia and a CDMA network in the US. A ROM could be built that allows a user to access Sprint's CDMA network while also browsing Verizon's LTE network for instance. Also, it puts pressure on Sprint/Clearwire to increase the speed of the roll out of their own 4G (Wi-Max) network. For more information on LTE, please go here.

thats insane, but from all i have read, Sprint still holds the record for faster data connection for a mobile device...

But Verizon is going down the drain anyways, over priced and will be sued soon by FCC

you are correct, 5-12 mbps down and 2-5 up

Technically speaking, LTE and WiMax are not 4g as "4g" has yet to be approved by any of the work groups involved. Most consider both technologies to be 3.5g because of this, though for marketing companies are throwing around 4g (sort of like the Wifi N debacle).

LTE Advanced has been put forth as a 4g candidate.

Either way, we won't see any of this tech in a "phone" proper for probably 2 years. This announcement is more relevant for data cards/dongles/date devices than phones.

The reason for that is LTE has no agreed upon method for handling voice calls, so it has to fall back onto 1x--but that method has not been agreed upon yet either. Building a ROM, assuming that was even possible, would only get to "roam" on Verizon''s old EvDO network for data (something we can rarely do now as Sprint doesn't have a 3g data roam agreement with them), but do nothing for voice, which last I checked is the main function of a phone

But you can do that in Baltimore today with Sprint and WiMax. The "real world" speeds and reliability between the two technologies still need to be tested. Too early to call without mentioning their "theoretical potentials".

I don't mean to be noob but..............

The wiki on LTE is talking about speeds of 100Mbps down and 50 up...................?

Yeah, they're usually talking about theoretical speeds, ideal situations, no traffic, switching and the range of the stations is low.

In reality LTE will be 7-12Mbps down and 3-5Mbps, which is similar to WiMax speeds. Those speeds are important for netbooks, MIDs, etc. Current smartphones would choke on those speeds and most people just don't pull that much data when checking email, surfing the web on their phones.

But lets be clear: the real winners of "4g" here will be who can launch the first with the most coverage/availability, not isolated speed tests. Both services will perform similarly in the field.
