Sterling Heights, MI | Good? I imagine the people who use 3G a lot will make the immediate jump to 4G.
Hopefully by then, the iPhone will come to VZW | |
|
 | | | Re: Good? If VZW has LTE in my area and its working the way everyone is talking about it now I will be one of the first to jump on board. And if they do have the Iphone with LTE avaiable I will be even happier. I have a touch and love the thing but deathstar service around here stinks so I stick with VZW.
One thing that I do hope though when it becomes available is that they give me more then 5 gigs a month when tethering. I am hoping they don't do what Rogers did and give people nice speed with a low cap.
Can someone explain to me how the backhaul for the cell sites is going to support this increase in speed? | |

Valencia, CA | Re: Good? Until Apple builds an LTE/CDMA chipset, VZW will not be able to use an iPhone.
Apple chose to build their device with 1 physical build, and since CDMA counts for ~ 12% globally, GSM/HSDPA is where it is. This is more of a going with the masses decision by Apple than anything. | |

MUCH better propagation techniques and less towers required. I bet they'll have LTE covering a large percentage of their footprint VERY quickly. | |

For an iPhone to operate on VZW (or any LTE handset for that matter), it will need to support CDMA/LTE. Or more ideally--GSM/CDMA/LTE. Qualcomm and others are working on such chipsets. It's possible Mobile WiMAX support could be included in such multi-standard chipsets for multi-band devices.
New phones need to be backwards compatible with the older technology for quite a while for fallback support. And old wireless networks need to be supported quite some time as well, to support existing customers who haven't upgraded yet. AMPS and TDMA were only shut down last year here in the US. GSM and CDMA still have enormous numbers of customers, probably well over 100 million voice customers. It might be 2018 before they can seriously considering shutting down 2G. Although that doesn't preclude re-farming some of that spectrum for LTE.
Also for a LTE device to operate on a LTE network, it needs to support that particular band. Granted this is something of a "no duh." But it's important to note as LTE will be deployed in a number of different bands, including: 700 in US & 800 in Europe (former analogue TV), part of the 2500-2690 in Europe (Clearwire has much of this in US), 1700/2100 (AWS in US), plus whatever re-farmed 2G/3G they can scrape together (850/900/1800/1900/2100). Most early devices will only support one band, it'll take some years to have multi band support.

MUCH better propagation techniques and less towers required. I bet they'll have LTE covering a large percentage of their footprint VERY quickly. All spectrum have attributes/characteristics that give it particular advantages and disadvantages. 700 MHz does propagate farther, making it far more useful for rural areas. A single 700 MHz base station could cover as much as a 1000 square miles.
However it doesn't work like that in urban areas. You can't serve the entire LA or NYC metro with a single tower, for a whole number of reasons--including physics. You'll probably need just as many towers as higher frequency bands because of capacity reasons. And you'd have to de-tune each base station so they don't interfere with each other.
ATT and VZW bought some AWS spectrum some years back, which is currently lying fallow to my knowledge. They'll probably deploy LTE there as well as 700 MHz.
All that said, VZW is among the most aggressive carriers with LTE in the US and the world. They've made no secret they intend to eventually overbuild their existing CDMA/EvDO network, and then some. | |

Arnold, MD | I think the influence came more from AT&T to build the iphone in such a manner. I'm sure they played (and paid) a part in the iphone development, hence the GSM-only Infineon chipset. Otherwise, Qualcomm makes a dual mode chipset used in the Storm and other BB world phones. No reason why an iphone could not have been made in such a fashion, barring cost or design layout issues, to give Apple 100% reach in the global cellular market. If the current frustrations with AT&T are any indicator, and Verizon comes to terms, I'm sure Apple will do whatever they need to do to reach the rest of the US market, whether it be a second build or a more universal single design.
With the ability to switch between major carriers more easily in the US once LTE takes off, I expect someone will make an LTE/GSM/CDMA tri-mode chipset. It only makes sense to have backward compatibility since the far reaches of the country won't see the upgrade for at least a decade. | |

Lancaster, PA | Fiber to the cell site and microwave back haul from a fiber hub.
End to end fiber to wireless carriers' switches. Verizon has been using the "fiber to cell site" approach for years. Many carriers are looking at the fiber hub / microwave solution as a cost effective way to deploy G4. Pitch the cost of a T1 and GO MICROWAVE. | |

| | | Re: only 30 carriers on lte ? Some countries are just only now getting EvDO rev 0. They'll probably get 4G LTE when the developed world switches out their gear for whatever comes after 4G.
They'll also have to find spectrum for 4G since they're not transitioning to DTV like we are. Not difficult (4G can work on other spectrum, not just 700MHz) but it's something to consider. | |

| Re: only 30 carriers on lte ? EVDO? Which countries are you thinking of? The only major countries with CDMA that I can think of are the United States (has EvDO) Japan (using W-CDMA/UMTS for 3g, LTE for 4g) and Korea (going LTE)
DTV? »en.wikipedia.org/wiki/Digital_te···he_world
almost every country in the world has begun or finished moving to Digital TV.

3 edits | Re: only 30 carriers on lte ? I am referring to South and Central America and the Caribbean.
There are quite a few countries in the Americas who have CDMA/EVDO. Some have it for phone service, some have it for data only service (laptop cards primarily).
Of course in Europe and Asia they're all about GSM/UMTS and they have DTV transition covered, but I am talking about the Americas specifically.
But even if you include the rest of the world, a lot of countries have EVDO coverage:

While AT&T has HSDPA and HSUPA, T-Mobile is not going with HSUPA and straight to LTE with the 3G network as a springboard.

| capped Whatever, it'll be capped at 5 gig like everything else.. why? Cause they can, but where else are you going to go... Right?
Not excited about technology as I used to be anymore.. They meaning all the isp's being greedy as hell have ruined it for me... I am officially going to get my 12 gauge and spend my time on the porch in my rocker acting crazy as hell... And i'm only thirty years old.... Christ thats going to be a lot of beer...
Thanks ATT, Sprint, Verizon, T-Mobile and the rest of you pretending to exist company's pending future buyouts from one of the big three.. Technology regression here we come!!!! Woohooo!! | |

| | another paid advertisement disguised as news LTE is not even here yet and Telco's are still trying to pay off their 3G investments.
Nothing but propaganda to slow adoption of WiMAX. | |

Valencia, CA | Re: another paid advertisement disguised as news I tend to agree to a certain extent. WiMAX did similar when it was being promoted as the next best thing to sliced bread.
Current problem with WiMAX is still the obvious - no handsets, no coverage. I do think they should be using it (IMO) to go against DSL/CABLE + Phone service as a form of fixed wireless.
If it was available  and cost less than DSL/Cable + phone, I'd use it. | |
