1Gbps Wi-Fi Coming Soon To a Billion Devices 202
MojoKid writes "Not only is 1Gbps technology heading for your Wi-Fi network by next year, it will be instantly über popular. The new 802.11ac 1G Wi-Fi standard hasn't even been ratified by the IEEE yet and In-Stat predicts that by 2015, consumers will have bought nearly 1 billion devices that use it. 1G Wi-Fi, which will use radio spectrum in a range below 6GHz, will be embedded in mobile phones, e-readers and automotive infotainment systems.The study predicts that Mobile devices with embedded Wi-Fi will make up most of the market. In 2015, shipments of mobile phones with embedded Wi-Fi are projected to approach 800 million. Also, by 2015, projections are that 100% of mobile hotspot shipments will be 802.11ac-enabled."
The fine print. (Score:2, Interesting)
Anyone care to guess what actual throughput will be? If 802.11n is any guide, I'm guessing roughly 10-20% of what's advertised.

Mostly the extra throughput will not be used. What is the real throughput anyway?
Unless you're streaming from a local server, your internet connection will be the bottleneck, and most of those can't saturate 802.11a/g. Even the highest speed FIOS & DOCCIS 3 rates can't quite saturate 802.11n.
The range will be more limited (5-6GHz doesn't propagate through walls as well as 2.4GHz). In dense environments, that's an advantage, but 802.11a/n on 5GHz already has that benefit.
A big issue with any wireless technology is latency. Higher modulation rates help that a bit, but most of the latency is in making sure it's safe for you to transmit, not in the actual transmission.
If you have a use case that needs higher throughput than 802.11n and isn't latency sensitive, then this will be a benefit, but for 99+% of users, it's completely unnecessary.

Hey, the Plague did great things for Europe - the drop in population made everyone more wealthy, and also helped workers gain more power and escape from serfdom.

I'm not so sure. I think this technology might not be useful for the opposite reason.
I've got a 100Mbit/15Mbit DOCCIS 3 line connected to a Linksys E3000 that sits about 10 feet from where I usually use my laptop (5Ghz N) and it's like Internet Nirvana. It's well matched and good hardware with bandwidth that is surprisingly delivered as advertised. However, it's only delivered as advertised because of diligence on my part. Twice now (NEVER reboot your DOCCIS 3 modem), I've been mysteriously bumped down to a 30mbit/5mbit connection. I've called to complain both times and, to my ISPs credit, both times when I've said, "Look, I'm an engineer. I've properly tested the line and it's 30/5", they've immediately put me through to a proper network engineer who, while obviously annoyed, did things like put a large file on a server that was 1-ish hops away and said, "FTP that over and see what you get". I was stunned. And the problems were resolved.
Having said that, most people I know have ISP issued routers and wouldn't even know how to test their connection speed to the router or the internet in general. It wouldn't surprise me to learn that half of them have upgraded to connection speeds that not a single computer in their house can actually achieve over wireless because they are using shitty ISP issued D-Link wireless-g routers that they tuck away in the place least conducive to actually getting a good wireless connection. The ISPs know this and certainly aren't going to start issuing 1Gbit wireless routers that will allow people to actually take advantage of the speeds they are paying for with every device in their house.
