UK Testing Wireless Broadband Via Airship
fruey writes "A team from York University, UK are about to test high altitude platforms, according to this article, as a way of bringing high-speed internet services to computer users in remote areas out of reach of broadband. They plan to use solar powered engines to keep the aerial platforms in position. The Capanina site have some more information about this stratospheric broadband experiment. More technical stuff can be found at the York University website
This technology could deliver broadband communications at data rates up to 120Mbit/s! Screw cable and xDSL, when will stratospheric be available near me?"

I assume this means backwards places like the Fens, Channel Islands, Welsh valleys and Liverpool. It might help to teach them what a computer and electricity are for first.
"Why is my net connection down?"
"The router crashed."
"Can't you reboot it or something."
"No, I mean it literally crashed. Some bird flew into it and the sucker fell from the sky. We'll be getting a replacement up in an hour or so."
It might bring a whole new meaning to "my network's gone down"

Q. Weather problems and air traffic?
A. It's 12 miles up. that's well above commercial air traffic, and i suspect (although i'm too lazy to check) most weather problems.
Q. Latency TImes?
A. According to the article, those will be a hell of a lot lower than satellite. Also, it seems to be boasting a very, very high rate of transfer.
Q. How many are needed for redundancy?
A. Well, none. If it crashes it does. Kind of like how, if your ISP gets blowed up, you ain't got no internet. This isn't yet considered stable enough for long term solutions. it's mainly just cheap braodband for areas that don't have it, until they get it - if that makes sense. I see more military applications than anything, to be perfectly honest.

Actually, theoretically never. Not to give you an RTFA, but the craft hovers at an altitude of about 12 miles -- well into the stratosphere. The stratosphere begins at about 15km (9mi) from the Earth's surface and is composed of less dense, relatively stable air. I say relatively because there is a lot of lateral mixing but nothing quite as turbulent as what we experience on the surface. The highest clouds form not far from the tropopause (cirrus, stratocumulus, et al), so weather and harsh winds would have no effect on the craft at all.
On Slashdot, we don't say "thank you." We say "that's enough..." -_-;
Heh, this made Slashdot. Cool. So, yeah. I know these guys.
Basically, the airships is question are built by a company named Aerovironment (www.aerovironment.com). I've known about them for a while; one of my good friends works for the company. Really cool stuff; the basic idea is that this giant fixed wing circles around a rural area in the mid-to-upper atmosphere (where the air is thin enough to reduce drag, but thick enough to support lift) using solar power during the day and battery power at night. Then you drop some cell / wireless data relays on the bottom of the plane (UAV, to be more accurate), and poof: Regional visibility of a satellite relay, without the lag of communicating with a device being 22,500 miles away in geosynchronous orbit. That it's much cheaper to deploy the device (and possible to recover it as needed) is just gravy.
Things haven't been trivial for Aerovironment -- they lost one of their fixed wings some time ago during a test flight in Hawaii -- but as far as I know, they're the leaders in developing UAV's that simply don't need to land.
