Verizon's network

Obviously Verizons LTE network is still newer then Sprints WiMax network so it has less users using bandwidth on it. I wonder though if having a large number of customers on Verizons network will actually slow it down it all considering all the bandwidth they purchased in the last auction?

Also thank you for taking the time to do these tests and post the results for those of us who want to know but are unable to perform these kinds of tests ourselves.

Verizon has about 20% of the spectrum that Sprint/Clear have for 4G. Put differently, Verizon's network will slow down as more users are loaded on. Sprint's will as well, but the reason won't be spectrum...

you can't just look at the amount of spectrum. You also have to check the efficiency. the 700mhz band is significantly more efficient at transmitting data compared to the 2500mhz band.

Yea and the 700mhz band is significantly more crowded then the 2500mhz band so there can be signal and frequency interference issues the the 2500mhz band Sprint operates in will not have to worry about. Secondly 700mhz cannot achieve speeds the 2500mhz band can reach. Which is why if clear chose to do LTE there speeds would be a lot faster then verizons. But the efficiency of the 700mhz band is extremely offset by the amount of Spectrum Sprint has as well as the pipe and spectrum efficiency of Sprints wimax. 😎

I think verizon actually owns 1/2 or more of the lower 700 band in most areas of the country. So I don't think it's "crowded"

At 2500 mhz it would take around 3 times the number of towers to cover an area compared to 700 mhz. High frequencies have low range. That's why those real high frequencies that sprint/clear own have never been particularly desirable for cell phones. They make for a very expensive network to operate.

Having a lot of spectrum is nice but it doesn't make your signal go further.

but they are not building something new, all they did was fancy up something they already had, its not something completely new, sooner or later its going to get over crowded and they will cap the 5gb and not allow you to go over it, with wimax it will started from scratch and it wont be overloaded with cell phone calls and such it can be dedicated to just internet...

They bought the spectrum they're using for LTE in 08 when the fcc sold the old UHF tv spectrum. Up until this point they haden't broadcast anything in it, aside from probably testing in preperation for this LTE deployment.

I'd have to do a little more in depth research on sprint's deployments but from my initial search it looks like sprint does voice and data using wimax. So voice calls and data share spectrum when people are connected to 4G. Voice and data sharing spectrum isn't uncommon though, it's uncommon to see them not sharing spectrum. Verizon is the only company i'm aware of who did voice and data on seperate bands because they had the luck that their 2G and 3G technologies could be simulcast AND they had 2 bands available to...

thats not how its done, thats the benefit of the wimax. sprint uses the 3g spectrum for their voice and msging and the wimax for data thats why you can browse the internet and be on a call at the same time with sprint and you cannot with verizon.

You will once there are LTE phones.

And Both LTE and Wimax will be fully data solutions in the future. VOIP for voice on the Data pipe.

Actually in order to do simultaneous voice and data you have to be using the same standard and band for both voice and data.

The reason that verizon currently can't is because of what I stated in my previous post, they use seperate bands for their voice and data.

AT&T can do simultaneous voice and data because voice and data calls happen using the same standard over the same band.

Verizon owns a majority of the usable 700mhz band. it's not crowded at all.

On top of that, for sprint to cover the SAME area with coverage, they need more equipment. Also they need additional equipment to compensate with how much interferance that band gets compared to the 700, or even the 850/1900 bands get.

They NEED the additional spectrum to compensate for these issues, it doesn't provide them the advantage you're implying.

Yes, the higher spectrum means higher speeds are capable, but at a signifigantly higher cost. Which, considering they are charging less for their services than their competitors, could be a very real issue unless they start making money soon.

So if the 2500mhz band transmits information faster then the 700mhz band, and Verizon is still getting faster speeds then does that mean LTE is faster then WiMax?

Possibly, when Sprint trailed lte they got 90mbs. But as of right now all it means it that Verizon's network doesn't have as much traffic as Sprint/Clear who have a much larger pipe for high speed data. But the fastest speeds right now are produced by Wimax 2. Also Sprints current speeds are not at capacity and are also being throttled back. Regardless a few mbs more are not gonna matter in the grand scheme of things especially when as of right now Sprint/Clear have over 50 wimax devices and verizon has only 2 on lte. 😎

The network launched not even 2 weeks ago.

How many devices did Clear have 2 weeks after they launched? (they most likely had more than 2, because they had home routers) but honestly. the "we have 50 devices" pr spin is terrible. It seams like they're hiring the people Sprint fires, and that's not a complement.


And you're right, that extra speed won't matter. what will matter is coverage. So if, going forward, Verizon has to put up (on average) 1 tower to cover a region that it will take clear 4 towers to accomplish (higher bands have smaller radius', higher chance of interference, etc) how do you think the deployment will look once the "lucrative" city markets are covered? Which one, do you think, will have a faster rollout?

"[S]ignificantly more efficient at transmitting data" in what way? The Shannon-Hartley theorem requires no allowance for frequency or wavelength, only bandwidth & S/N ratio. All other factors being equal, 10 MHz bandwidth of 2500 MHz spectrum has the same information capacity as does 10 MHz bandwidth of 700 MHz spectrum.

If spectrum won't be the issue that causes the network to slow down, what will the issue be?
