In other news, 5G users can now burn through their data cap in under 10 seconds!

Brilliantly put. I see some tech bloggers go through "specs" of speed, only to forget the data cap. If money is not an issue, then maybe, but most people usage over the cap will truly bite.

Correct me if i'm wrong, but wasn't 4G supposed to be 1Gbit/s?

1Gbit/s stationary, 100Mbit/s when moving.

That's good to know I just assumed transmission speeds always meant while moving since it is a phone, I never even thought it meant when stationary.

For Sprint, in most areas, 4G means 50Mbit/s when stationary within range of a WiFi access point, and 50 kbit/s otherwise.

With HSDPA and 4G a lot of people are using it to replace their home internet (not so much in the US, but elsewhere it's a big thing). Hence the current capacity crunch mentioned in the article

Translation: "The theoretical numbers we sold LTE with are a good target, maybe this technology lets us deliver that in the real world to all the users who want it."

From what I can tell, this technology isn't about making spectrum more efficient, but opening up new parts of the spectrum (10+GHz) that weren't usable before. edit: nice map of radio spectrum. Being able to use 28GHz seems like a massive leap. http://www.telecomcircle.com/wp-content/uploads/2009/11/Spec...

The short-term solution is to open up more spectrum to mobile use, but things are looking pretty congested. http://siliconangle.com/files/2011/03/spectrum_map1.jpg

We might as well drop the whole ?G classification. Since the US carriers started branding stuff 4G that wasn't anywhere close to spec its been a free for all. Marketing aside, the tech might have merit in its own right though. I think the Ka band isn't available for use in my country though...

4G actually means something, it's just not enforceable. The trouble is, the trademark was not acquired in time before it became a "generic term" which means anyone can call anything 4G.

I thought 28 GHz signals would be stopped by relatively small obstacles (thin walls). It's not a matter of detection; the signal is absorbed and there is none left to detect on the other side. How could they overcome this with an antenna array?

Edit: According to https://en.wikipedia.org/wiki/Ka_band this band is used for satellite communications, but it very susceptible to attenuation in rain. So it's very cool that a new antenna tech could improve on satellite downlinks, but it still doesn't seem practical for a cell phone.

Data cap's are indirectly related to transmission speeds so you may always be able to burn though the data cap in under 10 seconds, but competition will still slowly raise the cap as technology improves. IMO, the current 2+GB caps are not that bad, raise that to 20GB and you can watch a fair amount of hulu for example (~50+hours) without a problem.

competition will still slowly raise the cap as technology improves. Has not been my experience at all here in Sweden. Data caps have been lowered across the board over the past year as data speeds and availability has improved.

That's been my experience in the US as well. On EDGE/EVDO or even early days of 3G, unlimited plans were extremely common and fairly cheap. When 3G became more established and 4G/LTE started rolling out, 2GB is now the normal with massive increases in prices as you add more ($10/GB is common).

Strange, in Denmark they have been raised. You can get up to 1 TB mobile 4g lte plans for 70 usd (including 25% vat - http://www.3.dk/Privat/Mobilt-bredband/Abonnement/MB-FRI/).
