Verizon LTE Can Use the Monthly Data Allotment In 32 Minutes
adeelarshad82 writes "Verizon's new 4G LTE network is so fast that you can use up your entire 5GB in as little as 32 minutes. The 2010-era speeds are soured by the 2005-era thinking on data plans. Verizon has priced LTE pretty much like 3G to encourage data sipping, not guzzling. As soon as you start using the latest high-bandwidth Internet services, your whole month's allotment can evaporate in no time. According to a test, the network's speed maxed out at 21Mbps, which means that it takes only 32 minutes to smoke up the 5GB monthly data cap on the plan. While the 21Mbps speed was hit on a low traffic network, Verizon estimates you'll be able to get around 8.5Mbps with a loaded network which still means that the cap can be exhausted in about an hour and a half."
What if you are watching a streaming video? (Which of course means you don't know what size it actually is...)
There are lots of data chugging activities on the net that don't tell you how large they are, combine that with a greedy provider that wants you to go over your limits so they can charge you more, and your wallet is going to be taking the hit sooner or later.
Still cheaper than a teenager without an unlimited texting plan.
How are sites slashdotted when nobody reads TFAs?
Verizon's 4G LTE network isn't even available on phones initially, its limited to USB modems for computers (and Verizon's marketing of those USB modems and the associated plans is targetted primarily to business users); it will be rolled out to phones later.
So the more relevant question should be, "why do you need over 5GB/month in network data transfer to a computer, especially one you use for business?"
Sprint used to, then they amended their Unlimited plan to Unlimited* with an asterisk and a 5 gig cap.
Virgin Mobile Prepaid, however, is $40/month for unlimited 3G internet.. and uses Sprint's network. It's actually Sprint's prepaid brand.
I've pulled down 20 gigs and up per month (downloaded all my Steam games!) without issues.
However, this VM Unlimited plan is pretty new.
The real bottleneck that wireless carriers worry about is not their network. It's the capacity of a single cell tower to carry a finite number of simultaneous connections.
Have a look at the info about LTE frequency assignments. OK, all you hams out there, how many MHz of the frequency band to carry a data rate of 21MHz at the various assigned frequencies? How much frequency spectrum is available? Divide X by Y and you get the number of simultaneous full-speed downloads. Exceed that, and you have to start some sort of time-sharing scheme in which individual users grab a few milliseconds of exclusive ownership of each channel at a time. (Token Ring, anyone?)
Because of the way radio works, you can only get so much network bandwidth out of a particular frequency spectrum. You can do phasing tricks and subcarrier acrobatics to squeeze more out, but there will be a point at which you can't handle more devices per cell tower, no matter how much (wired/fiber) network there is behind it. And putting two cell phone towers right next to each other doesn't double the number of connections that can be handled; a phone connecting at 2410MHz to one cell phone tower will be putting out radio noise that a second tower right next to it will pick up. This is why AT&T is getting hammered in places like San Francisco and New York where there is a very high density of 3G users; they just can't add more cell towers. They're saturated; it's not because they're cheap bastards (they are), it's physics. That's how radio works.
Think of it this way: your FM radio has channels from 88.1MHz to 107.9MHz in 200KHz steps. Once all 101 channels are allocated, just "adding more towers" doesn't get you anything.
Smart phones differ from traditional cell phones in that they are "on the air" more than voice-only phones (insert teenage-girl joke here). A voice call might need 50kbit/sec for the duration of the call, and thus consume very little radio spectrum during that call (a handful of KHz). But a data session is a steady high-bitrate stream that can consume several MHz. Yes, interlacing occurs, but it really comes down to this: the limitation is how many MBits per second an allocated frequency spectrum can carry, divided by the number of simultaneous users of that frequency and their data demands. Once it's all in use, there ain't no more. Users get timesliced to slower and slower connections, until the granularity demanded by timeslicing and channel-juggling among X-thousand users of a single tower is so small that you can't even get a voice call through.
So yeah, I understand why wireless carriers would want to cap data usage. It sucks, but physics doesn't care how angry a consumer is, you can't sue to force 1000MHz of in-use spectrum to fit into 200MHz of allocated spectrum, and carriers can't throw money at physics until it goes away. Radio spectrum is a finite resource, data at a given rate requires a specific portion of that spectrum, and that's it. Something has to be capped. Data rate or data cap; something has to throttle usage, because there's not enough to go around for everyone to max it at once.
Everybody gets what the majority deserves.
