Help Should we worry about the 800mhz/1900mhz debacle?

Sprint is rolling out tower upgrades that they call Network Vision.

This includes 1900 MHz and a takeover of the old iDEN 800 MHz bands.

They have said explicitly that 1900 MHz is for LTE and both are for Network Vision, leading many blogs to insist that LTE will happen also on 800 MHz. But, I have yet to find a Sprint statement backing that up.

The advantage of 1900 MHz is potentially higher speeds. If you can get regular 3G coverage (already at 1900 MHz) then expect good service from LTE in that same frequency range.

Sprint said that the 800 MHz addition added coverage range for Network Vision, but if you read carefully, that could mean 3G (and likely does).

Most every website and blog you'll hit will insist that 800 MHz LTE is an upcoming reality for Sprint. Best to remember that they all quote one another with little fact checking.

That all said, specifications subject to change and our mileage may vary.

But right now, despite many blogs saying 800 MHz LTE, Sprint hasn't said that, and new Spirit phones are not spec'd for it. ;) :)
 
EarlyMon.....I will look it up as well, but If I'm not mistaken Sprint said with their "Network Vision" they'll have the 3G speed's up to their current 4G (Wimax 2500 band) speed! I.e. In my area I average about 4 down, and with their network vision they will get the 3G speeds to average 3-5 down! If this can really happen, how so!? Is this just how Att and T-mobile are doing the HSPA+?
 
we used to discuss about how Wimax and LTE was different... and the advantages of each.

remember how wimax was more open in use.
while LTE gave the carriers more control of the type of data you get, and potential charge for different types of data (VOIP vs websites vs media streaming).

i was hoping for wimax to get better.. but it does suck in performance. (sprint / clearwire implementation just sucks).
so now we are moving to LTE.
and sprint has said data will be unlimited.. for now.

but using the data throttling as an example how they get around the "unlimited' feature (AT&T)...
sprint can use LTE to ..
1. Throttle us from the big speeds (20+ MBs) to current 3G speeds (.5 MBs) because they can say that is what we are used too... after reaching some some top limit (maybe 4GB /month).
2. use LTE to separate types of data. Unlimited on most websites, but charge extra for music, video streaming and certain websites (hulu, netflix, etc...)

i feel this is just around the corner .. Sprint is a corporation out to make profit.. and they will follow the other carriers.

But it won't happen for awhile. Sprint financially is in trouble they need more users. And then people can still go to T-Mobile for capped data speeds for 30 dollars less

what is a while?

i can see it happening within 4 yrs.
just think of all the changes and lost of benefits within the last 2yrs.

Not going to happen. I think cdma tops out at around 3.1

If they go to EVDO rev B, it tops a bit higher.

Per wrongepedia (who I think is right on this on this one) -

Comparison of wireless data standards - Wikipedia, the free encyclopedia

Although it's not consistent with itself. You can stack up chunks of the spectrum to double or triple that max number.

So can they? Ummmm - yeah.

Will they? Ummmm - let me get back to you next year. ;) :)
 
It's cool here as well as elsewhere.

I've not forgotten my promise to provide some forum/thread structure here - that's going to happen soon, so meanwhile, just post where you think it best fits the discussion at hand. ;) :)

And 7 Mbps down on 3G is quite possible, per my previous post.
 
The concern with LTE at 800mhz is, as previously mentioned in this thread, the lower the frequency the less data that can bee sent in the same amount of time, but over a greater range.

And for those thinking multi channel cdma is a good idea, go post a thread on these forums about "battery life with 3 or 4 3g modems on a single phone" and see how many people would be interested in that device... Imagine a cell phone with a 25,000mAh battery that gets 4-5 hours of use before needing recharging (made up numbers, but you get the point), not to mention it would have to be 3"-4" thick just to hold the battery.

So what happens when lte gets switched 800mhz and your new lte phone can't read it? What is the point? I don't think sprint would mess that up.
 
Also I read that the antenna is built on the chip and the chip can read lte 800 MHz but is locked out can't it be unlocked down the road to read this spectrum

By chip, do you mean the main processor? That has all of the various modems built in, including for those for LTE. None of those are locked.

The modem section connects to radio chips. The LTE radio in the LTEvo is 1900 MHz.

HTC EVO 4G LTE tech details revealed in FCC OET filing - Sprint 4G Rollout Updates

The antennas are attached to the inside of the top plastic cover. Here's how they look for the One X. It will be similar on the LTEvo.

htc_one_s_review_sg_23-580x405.jpg


The phone radios aren't built into the main processor, antennas aren't built into chips, and the only LTE frequency spec'd by HTC and certified for use by the FCC is 1900 MHz.

Hope this clarifies! :)

PS - the FCC has yet to approve any 800 MHz LTE transmissions for Sprint towers. ;)

both...LOL...Isn't that the whole point, that eventually all the phones on the network will connect to both 1900 and 800mhz?
Click to expand...

Exactly. CDMA will connect to both. LTE will connect at 1900 MHz.
 
S4gru says that they will have an upcoming article on 800 MHz LTE updates very soon, and that everything will be in place at the towers so that upgrading there will be plug and play simple, taking a tech only a few hours per site to perform the upgrade. Plus, hinting at 2013.

And there's speculation that the LTEvo could be re-certified by the FCC.

A schematic or proper teardown would end the speculation about the LTEvo's capabilities. But so far, all HTC has claimed for the phone is 1900 MHz LTE.

I find it odd.
 
Does the antennae being partially on the inside of the cover mean the One X (and the LTEvo) will turn themselves off if you pop the back cover off, much like the Windows Phone Titan II? Not that I have much reason to remove the back on a phone that's powered on, just curious.

I predict it will likely only be halfway through if not almost all the way through the lifespan of the phone before the 800 Mhz comes live and the lack of an 800 Mhz LTE radio becomes a liability for the phone.

Sprint will replace iDEN network with LTE by 2014 | The Verge

Sprint will deploy LTE on its 800MHz network by 2014, according to Bob Azzi, senior vice president of networks. In a briefing at the carrier's corporate headquarters in Kansas Azzi told reporters that the move is yet to be approved by the FCC, but the process has already begun and should proceed smoothly.

To follow up, as predicted, the LTE 800 Mhz network will come online two years -- two years from the launch of the HTC Evo 4G LTE, so people will be freed up for a new upgrade by that time -- presumably for a new HTC Evo 4G LTE 2MAXETREME, now with 800 Mhz antennas!!!11111!1!.

edit: EarlyMon beat me to the punch by 4 minutes. The Earlymon catches the worm. Sigh. :)

That's awesome! By that time the Evo MegaTron will be out, destroying all!:D
