Default HTC EVO 4G 2012 Phone

I'm curious about whether the EVO that comes after the 3D will have it set up so you can utilize CDMA/LTE/GSM. Or is this even possible? I love my EVO and I cannot accept the 3D as the brother to my 4G. Bring your "A" game HTC for 2012. You want to bring in the corporate folks, give them a phone they can take anywhere in the world.

It is not out of the realm of possibilities but let's say it was a true world phone... You would have an LTE antenna capable of all frequencies that LTE will run, one for CDMA at all freqs, a GSM at all freqs, a WiMax (assuming that is still Sprint's main 4g tech and it will be) antenna, then your WiFi antennas (2 for N) and Bluetooth antenna. Then all the other goodies and a dual core processor at the least. The phone would run hot and battery drain would be insane (major speculation on my part), and while it sounds amazing it isn't very feasable for Sprint or any other carrier to have this built.

Thanks for squashing my dreams. I delploy a lot and it would be nice to choose between CDMA networks or GSM during my travels. GSM would be cheaper because when you go to Korea and use a CDMA phone from the states you will get a $1000 cell phone bill. I expected that type of bill. Correct me if I am wrong but the Thunderbolt has a sim card in it. So you can go to different country and utilize LTE to call back home with google voice for example right.

I am sure sooner or later someone will make this phone so dreams are not squashed. As far as the LTE question well to my understanding it will depend on the frequency that the country you are in is using for LTE just like with GSM and CDMA and WCDMA and every other band BUT I could be very wrong about this.... I know Verizon is using the 700mhz band vs. 2.6 ghz that many other's may go with because they have that much coveted range of spectrum. Also I don't think any LTE Roaming has been hashed out yet since it is such a new tech.

AFAIK the sim is for LTE (data) only. Having a world phone isn't outside the realm of possibility though, however I am unsure of when, if ever, Sprint has had one.

Keep a secondary phone for the overseas trip.

I plan to keep my HTC touch pro2 for when i travel, and buy the HTC EVO 3D for US.

it would be hard to get all them in one phone.. but not impossible.

heat??? why?
would all the antennas need to be on and active at the same time???
one for voice
one for data
one for wifi
one for bluetooth
which is what they do now.... right?

I posted this in the Winax/LTE thread and thought it might have some relevance here as well.

~I pose this question in form of a hypothetical scenario. My buddy just bought a Thunderbolt and wants to test out his Hotspot feature while connected to LTE. EVO 4G accepts and connects to the provided Thunderbolt wifi hotspot signal. EVO 4G conducts a speed test to satisfy the curious Thunderbolt. They both witness an increase in broadband speeds and prove Thunderbolt is indeed receiving an LTE high speed connection. Now, pretend the Thunderbolt is in fact a cell tower receiving LTE data and has the ability to transmit a Wifi signal aka Wimax. Would this not make it possible for all current Wimax devices to use LTE or Wimax? If something as small as a cell phone is able to accomplish this feat, why not at tower? Wimax is nothing more than a nuclear powered wifi hotspot signal, could the same not be duplicated? Could this be what is taking place with sprints leap frog program?~

I have found other sites talking about EVO 3D being GSM in overseas market. HTC own site now pulled stated it is going to be support GSM in EVO 3D as well. I read also that while EVO 3D is using 8660 dual core snapdragon it's being processed differently then the old 8660? I just find the whole thing a little confusing and why Sprint, Qualcomm, and HTC are not more forth coming with information. Is anyone else seeing the need for secrecy on this? Think this would be a sale point not something to hide!

No this is not what's taking place in "Leap Frog".

You're example isn't what it seems to be... The Thunderbolt is taking the data from LTE, then acting as a Wifi router to the EVO. It's the same as a Wifi router connected to your wired home connection.

Let's say you have broadband internet at home, but no wifi router. Without a wifi router, you can't use your EVO on your home broadband connection because the phone is not capable of directly connecting to your home internet connection.

Now you might saw, hey ... Maybe "Leapfrog" will just start using Wifi. While that is possible on the tower side, it won't work in a real world application. The reason is your handset can't transmit at the distances needed in a mobile application. Try putting a few hundred feet of distance from your wifi router and your phone and see how well that connection works. Wifi is very distance limited due to power output.

BTW, Wifi and WiMax run on very similar frequencies... WiMax has greater distance because of power out put from the tower and your cell phone. That's part of the reason that WiFi will drain your matter slower then WiMax. Your phone doesn't need to send as strong a signal.
