For markets where capacity will be an issue, VZW can tap into their AWS spectrum as well. Too bad VZW didn't get enough AWS spectrum to cover the entire 48 states. They only have enough to cover the eastern half of the country & Hawaii. Those licenses are 20mhz. So 10+10 would be the only way to go on that spectrum.

That is incorrect. Neither Sprint, T-Mobile, or Leap participated in the SMH auction. (metroPCS acquired a single license for the Boston metro area.) You may be confusing this with the AWS auction, in which T-Mobile, metro, and Leap acquired major spectrum holdings.

I think you're right, my fault. It is supposed to be a weaker signal that'll need more towers though.

For major markets on the eastern side of the USA (especially places like New York, Chicago, state of Florida), the 700 band may not be enough. For markets where Verizon only has the C block, the AWS licenses will come in handy. Verizon will eventually tap into that as well, though they won't have to use it right away, like AT&T will in areas that they don't have 700 band (or have 700, but not enough).
Yes, AWS is like PCS. It needs more towers to have about the same coverage as 800 & 700. Unlike 700 (except for the regional C block), AWS only has to be built out by population. For now, 700 is priority, as it has a timetable for their network to be built out in that band. AWS doesn't, and Verizon will sit on those licenses a while longer. But they will tap into it if they think they don't have enough capacity in specific markets on 700.

How exactly is a dual band network ( 800/1900 or 700/1700 ) network engineered? Does the handset utilize the signal that is strongest?

There's a primary and a secondary. If your primary is 700MHz then it will hold on to it until it runs out of capacity, then goes to 1700 if it can get a signal.
If the primary is 1700Mhz, then it hang on to its signal until it fades then it moves to 700MHz.

Apparently there are already Verizon's 4G cell sites being constructed and the cell site antenna panels are clearly larger than their 800 and 1900 MHz counterparts.

I doubt there is any sort of widespread LTE deployment until 2011. I just see so many ways of hurt this technology is being deployed with. CDMA fallback is a recipe for FAIL in particular... why didn't they go HSPA+ as a bridge then went LTE? They're just locking themselves out of the advantages of adopting LTE with this approach.
What a bunch of idiots.
Fiber backhaul for Verizon in Southern Illinois in 2013 - about time.

Could you please enlighten us as to the advantages of going HSPA+, given the fact that they have a very mature CDMA network. From what I understand Verizon wants to keep their 1x voice network around for a long time and use LTE for data only until 2018-2020.

...............
Erik Neitzel, distinguished member of technical staff-network specialist at U.S. Cellular, told attendees at the LTE America’s event that antennas needed to support the 700 MHz band would need to be between 8 and 10 feet tall and around 14 inches wide. “You will have to run structurals on towers” to support the antennas, Neitzel said.

I don't know.. that rollout schedule is ambitious, but I think it's doable. I wouldn't say for sure they'll do it but I won't be surprised if they do either.There's ambition and there's reality. I guarantee you that VZW won't have 25-30 up by year's end. Still, no matter how many markets they manage to get up and running by year's end, assuming they get any up and running at all, the question becomes how well built out those markets will be.
Out "in the sticks" no. In the city? Who knows, I thought in places like New York City cell sites were already spaced around 1 block apart.I know that 700 MHz is the best possible frequency to deploy a wireless 4G network due to its range of signal, however, will Verizon have to position the cell sites in close proximity to one another (e.g. a 1900 MHz network) to ensure capacity?
From what I've seen this is not true at all. I mean, it IS true that there's a few areas that are still 1X only, primarily Alltel purchases that they have not upgraded yet. But I've traveled a lot and every indication has been that they have EVDO on (almost) every site, not some subset. In markets where they have both 1900 and 850 spectrum, EVDO deployments were initially 1900-only but in most cases they've added 850 EVDO as well. (The big exception I noticed was I80 through Ohio, 1900-EVDO on 850 spaced sites... it puts a crimp in things to have the aircard drop to 1X every 5 or 10 minutes).Even now, not all of Verizon's towers do 3G, only the 1900MHz ones (and the 850MHz ones where theres a large gap in coverage).

What?? Why would they waste time and money on HSPA+ when their CDMA network is very capable. This probably would have delayed VZW's deployment of LTE.

CDMA 2000 has a long life in front of it. Between 1x Advanced and DO Advanced and new vendors putting in a lot of development effort into it, CDMA still has a lot to offer.
Phone Collector
LTE provides...
- For every 20 MHz of spectrum, peak download rates of 326.4 Mbit/s for 4x4 antennas, and 172.8 Mbit/s for 2x2 antennas.
- Peak upload rates of 86.4 Mbit/s for every 20 MHz of spectrum using a single antenna.
(source: wikipedia)
Since Verizon is using 10 (downlink) + 10 (uplink) FDD cells (obviously, since they only have 22MHz in the C block), that means they'll get about half of these quoted rates. So if they use 2x2 antennas they'll get 43 Mbit/s on the downlink and 43 Mbit/s on the uplink (which is about what WiMAX delivers in a *single* TDD 10MHz channel). Or if they splurge for 4x4 antennas they'll get 163 Mbit/s down and (still) 43 Mbit/s up. Remember that to take advantage of the 4x4 bitrates the subscriber equipment must also be 4x4 capable, which is quite a bit more expensive. Phones probably won't be 4x4 for a long time.
That's for a single cell. Now, how wide is that cell? 700MHz signals go farther and penetrate buildings better than 850MHz. So that means your cell size can be larger, and you don't need as many towers.
BUT: if your cell size is larger, it'll cover more people. The more people per cell, the less bandwidth-per-person. So Verizon may need to deploy more 700MHz cells in urban areas to ensure that urban users get the same bandwidth as less populated areas. Which reduces the coverage advantage that 700MHz is supposed to bring to the table, at least in the long term.
In the short term they can drop LTE sites onto their 850MHz towers, dial down the power a bit to reduce inter-cell interference, and live with the bandwidth issue until they get enough users to make it a real problem instead of a theoretical one.
