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.

lol LTE wont touch the speeds Sprint 4G ill bring...

Re: CDMA to LTE Data Handover Completed..
 

correct me if im wrong, but LTE is faster than 4g? I read somewhere that verizon will be getting ~10-14 mb/s

Re: CDMA to LTE Data Handover Completed..
 

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

Re: CDMA to LTE Data Handover Completed..
 

well thats with their 3g technology, LTE is more advanced than 4g from what i understand.
Yeah true but i dont really have a choice, im on my dads plan and since im under 18 i cannot get my own

Re: CDMA to LTE Data Handover Completed..
 

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...................?

Re: CDMA to LTE Data Handover Completed..
 

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.

Sprint is planning on releasing the TouchPro2 with full 4G readiness

Re: CDMA to LTE Data Handover Completed..
 

Well then you're the only one who knows this and I must say, I thoroughly disagree :silent:

Touch Pro 2 is EvDO RevA only with Wifi. No Wimax.

Re: CDMA to LTE Data Handover Completed..
 

I second this, Sprint's Touch Pro 2 is EvDO RevA, this is a 100% fact. It is nice that it's a World Phone, but it is RevA.

Re: CDMA to LTE Data Handover Completed..
 

I believe a radio update can cure this though, no?

Re: CDMA to LTE Data Handover Completed..
 

nope its hardware, not software. A radio cannot upgrade the hardware on the tp2.

Re: CDMA to LTE Data Handover Completed..
 

A good insight what the future of cell phones and it services has to offer :) I just hope that the hardware of future phones increase faster than the data speed being upgraded now.

Re: CDMA to LTE Data Handover Completed..
 

Agreed... Without the hardware to access the quicker data speeds, there is limited use for the speed..

Re: CDMA to LTE Data Handover Completed..
 

Sprint doesn't have 4G, even if they claims that is is a 4G carrier. 4G is going to be a constant with LTE or WI-MAX, both will be a ip based network getting speeds of up to 10-12Mbps download and 2-5Mbps upload. In sprints crazy effort to regain customers they are claiming that REV-A= 4G which plain isnt true. its the 1st revision to EVDO< all they are doing is buffing up their network and making all their towers REV-A capable. Verizon is going with LTE(long term evolution). There is a substancial difference between the two networks and authentication on the server end of the data connection. The only phone provider currently that has manufactures a device that can support the LTE network currently is Sony-Erricsson. Either way eiher 4G technology is not going to hit the states until at least 3rd quarter 2010.

Re: CDMA to LTE Data Handover Completed..
 

Where is Sprint claiming Rev A is 4G? They are most certainly not advertising it that way. They are advertising that they are the first to launch 4G in the U.S., which IS true. They are.
Err, completely false.

Sprint has launched "4G" Wimax in July and is continually adding cities. You can buy the modem card now and it is $10 extra a month for access.

Here it is being used and the speed test in Baltimore.The U300 on Sprint already does 3G/4G.

Sprint won the 4G battle for launching and coverage. Verizon has to play catch up now.
