UK Testing Wireless Broadband Via Airship 222

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?"

      Actually, theoretically never. Not to give you an RTFA, but the craft hovers at an altitude of about 12 miles -- well into the stratosphere [wikipedia.org]. 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.

        OK, having read the article, I was too simplistic, but not enough to change the argument. The airship operates at ~12 miles and covers a 40 mile circle. If it has a ground station directly below it (roughly speaking), then if you are on the edge of that 40 mile coverage, the max range your wireless signal would need to traverse is ~42 miles each way. So a two-way comm would traverse ~84 miles. This is still MUCH less than the ~112,000 mile range a two-way comm signal must traverse via satellite internet

      What's the terminal velocity of a wireless router anyway?

    • The problem is controlling the altitude in day vs night scenarios. During the night, you'll be much closer to the weather. The balloon can't fly nearly as high then, unless you want to control altitude by adding/dumping gas a lot.

    • 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.

      Well, sure, the blimp will be above any bad weather. Meanwhile, the users will be below the aforementioned bad weather. Isn't that a problem?

    • Latency: 12[miles]=19.8[km], 19.8 [km] / c [km/s] = 19.8/300000 [s] = 0.000066s=0.066ms=660ns for the light to travel up. That's 1.66ms to get back down again, maybe a bit more because it's diagonal. Add the delay for 3 times (client, platform, isp) the wireless equipment and it's still pretty damn fast.

    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.
