Be Careful with the "Simultaneous Voice/Data Claims
For those who don't live in areas covered by LTE, or when you can't pick up LTE signal for any reason, you will be on 3G/CDMA and it will then work like any other Verizon smartphone! And who knows how well the Thunderbolt will be implemented with 3G fallback. For example, if you are on the internet and move out of range on LTE, will the connection stay open? What if you are on the phone when y...
Unless Tbolt has 2 CDMA radios (which is possible, we already know there's 2 radios to begin with), then when you go into a 3G area, you're going to have a problem. End of story. Dual "intena" or not. (and we already knew it had a dual antenna, since CDMA and LTE are different frequencies)
straight from corporate emailing. so it does just not as well
In other words, it might work, but it might not, nobody is going to make any promises about whether it will or will not work in any given area, and even if it does, nobody is going to make any guarantees of the quality of the result.
Once again (maybe read this more slowly, it might sink in) unless there are two 3G radios (or the 4G radio can "fall back" to 3G, thus giving you two 3G radios at the same time), or they are doing something VOIP, or VOIP-ish, then it simply isn't technically possible. I wouldn't put it past HTC to put a dedicated VOIP in there, and to have some arrangement with Ve...
The dual "intenna" (which I assume is a Verizonism for "dual internal antenna") is required for any 3G/4G phone. This is because Verizon's LTE frequencies are in the 700mhz band (UHF TV spectrum taken from the public by the FCC and sold off to ATT & Verizon for billions). The frequency and LTE signal are quite incompatible, so until there is enough 4G LTE coverage verizon will be selling dual band, dual radio devices for a long time.
The LTE radio won't work on 3G...
The ability to use data while making a call is enabled by the 4G network. If you are not in a 4G area, it will not work. If you do pick up a 4G signal as they are continuing to develoop in 3G areas, the ability to use data while on the phone is weak and should not be relied on.
While Verizon has more 4G markets than any other carrier, including airports in major cities, it is not everywhere. I am lucky enough to live in a 4G market, anywhere else it's sold customers should not expect to use both functions simultaneously.
This is the tech that allows the thunderbolt to talk and surf at the same time on a 3g network. It is one of the very first handsets to support SVDO. All phones with the qualcomm's latest EVDO chipset should support this feature, but that also doesn't mean every phone coming out is capable of it. Look at the iphone 4 it still only supports EVDO since its using a last gen chipset.
So...not sure where you're getting your information, but it's wrong.
Talk about misinformation....simultaneous voice/data works without a 4G connection. I have to travel over 20 miles from my home to reach any type of 4G reception. Simultaneous voice/data works flawlessly from my home....3G only.....no 4G.
