Yeah dude. On launching day, take your laptop with a wireless card, and hide behind a bush near the launch site. Just about when they are ready to let the balloon go, run out of the bushes with a "Whooo hooooooooallyourballoonarebelongtoussssss!" and grab onto the bottom of the balloon. It will go up and they will probably shoot at you with M16s but chances are they will not be expecting this and they will miss. Then, when you are high enough up there, turn on the laptop and with any luck you'll drift over San Franciso and you can get some sweet wi-fi action from a defunct dot com with its wireless network still running.
Oh wait, you meant how can this help you get wireless access while you're still on the ground. Well... yeah.
The height isn't the issue -- according to my first search result, here, GSM's extended range cells extend to a radius of 60 kilometers, or about 200,000 feet in mobile to base station distance. The only reason GSM is normally limited to 17km distance is for frequency reuse and timing considerations. With base stations in balloons far above the earth you pretty much eliminate multipath interference...Except maybe from the ground beneath your feet.
The claim that gives me pause is that the balloons will cover 100,000 square miles. That's a hypotenuse of about 180 miles at the edge of the cell.. That may indeed require a little more transmit power.

Also each Baloon will have $300 worth of kit attached to it.

747's and other commercial air traffic fly no higher than 45,000 feet. These weather ballons, as mentioned in the article, float along at 100,000 feet. The chance of one of these weather ballons running into a commercial airliner are *very* remote.
However, I'd still like to know where they all end up!
... because now when the Superbowl or World Series is in town, Telephone companies can put these things up to help maintain reasonable wireless service. Maybe these could have even helped avoid the cell phone blockouts in NYC on 9/11
About half of that would go toward equipment: $300 worth for each of the 50,000 or so balloons that would be launched over the course of a year.

Clearly using free-floating weather balloons has a number of limitations and disadvantages.
Now we know that NASA has great plans for its solar-powered airplane -- including acting as a semi-permanent flying repeater-station, but I wonder if smaller, cheaper options might not be available.
For example... what about a much smaller (say 20-30 foot span) autonomous craft designed to soar thermals during the day (while charging its batteries and gaining as much altitude as it can) -- then revert to battery power and/or gradually descend during the hours of darkness.
If the energy required to keep these craft airborn in the longer nights of winter was greater than that availble to be stored during the day then they could carry a fuel-load to power a high-efficiency internal combustion engine (probably a very small diesel engine). Every week or so the craft would have to land for refueling and maintenance -- but that's not a big deal.
Just like the US military's Predator RPV, they could be programmed to land on a runway set aside specially for the purpose.
The cost of a smaller craft, particularly one that wasn't totally reliant on solar-cells, would likely be much less than NASA's efforts -- thus allowing more of them to be built for a given budget.
By using more craft, they could cruise at a much lower altititude than either the weather balloon or the NASA craft.
Using modern composites, low cost GPS, and other "affordable" technologies, such a craft could likely be built for less than US$10K.
Assuming a 50% duty cycle, a fleet of 10 craft could cover a huge area at a much lower cost than towers, and with the ability to dynamically vary the coverage area if required -- simply by repositioning the craft.

Over the summer (in the southern hemisphere), I worked to help launch ozone measuring balloons, (same idea, more equipment), and we launched them only in fairly calm conditions. A balloon full of hydrogen is a fairly scary prospect when it's getting blown around. Does this also mean a commercial company will be putting extra pressure on the NWS to launch in potentially unsafe conditions? Scary thought!
"Since the chance of finding a balloon once it falls back to earth is remote, the company isn't counting on getting any equipment back once it is launched."
This is just great! I was wondering how I was going to get the equipment for my own wireless network!
Theoretically , you should be able to pinpoint the last known position of a repeater before it went offline, by triangulating its position from a few ground stations. All you'd really need is a low-power "save me" beacon to home in on when it hits the deck. Presuming that there is anything left when it hits the deck, of course.
Maybe someone could build a distributed client that measures signal strength and delay times to it's repeaters and (with a few other clients) triangulate positions from there. Would be good to have a webpage of 'downed wifi equipment' to trawl through... just in case.

LOS ANGELES (Reuters) - Actor Jim Varney, the voice of Slinky Dog in the "Toy Story" movies and the bumbling handyman Ernest in TV ads and a popular series of slapstick films, died Thursday of cancer at age 50, friends said.
Varney, who lost two-thirds of his right lung to cancer in September 1998, died before dawn at his home in Whitehouse, Tenn., outside Nashville, his spokesman and former wife, Jane Varney said.
"He passed away very peacefully," she said. "It all happened rather quickly." His death came just months after he reprised his voice role as Slinky Dog in a sequel to the 1995 computer-animated Disney hit "Toy Story."
A native of Lexington, Kentucky, Varney is best known for his role as Ernest P. Worrell, the grinning, tool-belted bumbler he has portrayed in a host of television commercials. His character always appeared opposite an off-camera, silent neighbor, whose attention he got with the line "Hey Vern!" before launching into a hard-sell.
His Ernest persona has been the star of a series of nine slapstick comedy films dating back to the '80s, including "Ernest Goes to Camp," Ernest Saves Christmas," "Ernest Goes to Jail," "Ernest Rides Again," "Ernest Goes to Africa" and "Ernest in the Army."
The Ernest character originally was created to help promote a newly opened amusement park in Bowling Green, Ky., his longtime attorney and friend, William "Hoot" Gibson, said.
His battle with cancer was first revealed publicly in November after questions were raised about his loss of hair when he was seen at public appearances in connection with "Toy Story 2."
Following his 1998 lung surgery, he suffered a bout of pneumonia, then underwent radiation treatments after cancer was detected in his brain in January 1999, Ms. Varney said. She said cancer also was believed to have spread to his spine. Friends said he had been a heavy smoker.
Still, he continued working, and "it's really been in the last three months that he was laid up, not able to get around," she said.
Varney will return posthumously to the big-screen in two upcoming films, according to his friend, Gibson.
He co-stars with Oscar-winner Billy Bob Thornton in the comedic love story "Daddy and Them," scheduled for release by Miramax Films later this year. In the film, written and directed by Thornton, Varney plays a character named Uncle Hazel, whose relatives are trying to rescue him from prison.
He also will supply the voice of a cook named Cookie in the upcoming Disney Animated Feature "Atlantis," due for release next year.
But then none of the/. editors would be able to post stories, because their karma would hit rock bottom in a week!

A friend of mine who does some work for NASA was describing another wacky concept he heard about to expand wireless coverage. The idea is that enough commercial planes are in the air at any moment, and are spaced evenly enough, to provide coverage for much of the country. Certainly major cities would be well covered. And the nice thing is that busy travel times coincide with peak calling hours.
Unless off course planes are grounded for whatever reason (remember 911) or pilots go on strike etc. Besides disrupting the traveling infrastructure you would also disrupt (some of) the communication infrastructure.
Let's not also forget the "Please turn off all electronic devices during flight" rule. I highly doubt the airlines, or let alone the FAA, would allow 802.11b equipement to be mounted on commercial airliners. I'm sure it's feasible, and with enough work, a solution could be found.
It's a good idea though... and I have to admit that a national meshed 802.11b network based on planes in the air would be very cool!:D

The concept of putting transmitters in the sky isn't new. Iridium has been doing worldwide telephone coverage by using satellites for years. The whole weather balloon receiver thing, while it's an interesting concept, sounds like it would be error prone (the coverage would be inconsistant due to weather balloons going up or down) and costly (To quote the article: "The company estimates its annual operating expenses at $35 million per year. About half of that would go toward equipment: $300 worth for each of the 50,000 or so balloons that would be launched over the course of a year.").

"The balloons typically hover at about 100,000 feet for about 24 hours."

The balloon flights actually only last about two hours and then the balloons break. In fact the balloon flights in question are done world wide at 0000 and 1200 UCT (Used to be GMT). They record temperature, humidty, air pressure and by triangulating from the ground tracking antenna you can calculate upper level winds.
I'm actually being generous with the length of flight. The time of year has a lot to do with the length of flight. The calculated height of the flight is related very much to the air pressure and for a flight to be valid it generally must be below 100 millibars. (The higher the balloon the lower the millibar reading). A flight reaching 3 millibars is around 120,000 ft. Summer flights usually have balloon bursts below 15 millibars. In winter early bursts, above 100 millibars, can require a second release, provided it happens within a given time window. The weather instrument package is called a radiosonde. Two types of upper air balloon a generally used for launching off the surface. For calmer winds a soft cheap latex balloon called a Kaysam is used and for adverse wind conditions or launch from a ship at sea a severe weather balloon called a Totex is used. (Totex is more rugged and more expensive)
They say they plan to hitch a ride on the existing balloons. The short duration is going to be a problem. The balloons expand as they rise and then go BOOM
I worked as an Aerological Observer for Environment Canada at a variety of Arctic Weather stations for about six years sending these suckers up there! There are long duration high altitude balloons out there, but the upper air program the article refers to doesn't use them, and the balloon shown in the photograph is of the variety to quickly put a few "holes" in the flight duration claim!

I've launched a rawinsonde a few times for the NWS, and frankly I don't have a clue as to where they think that these things stay up in the air for more than MAYBE 6-7hrs, let alone 24.
BTW, balloons burst about 2-3 hours after release, then they fall back to the ground via parachute. Granted it's a slower trip back down, but still...
I'm thinking they've taken too many pulls off of the hydrogen tank.
Using 3x10^8 m/s for speed of light, I make it 0.1 ms = 100 usec one-way to the balloon, i.e. 0.2 ms for ground-to-ground via the balloon. So the wireless part will be fine as far as Quake is concerned - it's just the other parts of the trip that may add latency.
In practice, latency may be much worse than this - look at GPRS, where latencies are many hundreds of milliseconds (often half a second) even though the wireless distances are much shorter. Wireless links use a lot of extra error correction and in the case of GSM/GPRS, packets are sometimes split into much smaller frames that are then interleaved with other frames - this is because GSM is voice-centric and this works well for voice. Not sure if GPRS has a better coding that avoids this, but if this balloon system is designed for data it should avoid some of the overhead.

The balloons themselves are made of latex, a natural substance derived from plants. They decay in ultraviolet light and break down quite naturally. An airplane hitting one of the balloons probably wouldn't notice. An airplane hitting one of the payloads might suffer some damage, but the construction of those radiosondes is for lightness, not durability. How much punishment do you need to take, riding up into the sky under a balloon?
Of course, all the balloons come down by themselves within a rather short time. Sheer UV and ozone embrittlement of the balloon envelope will do it if nothing else does. They burst and come down in rather small pieces (if you want to see what happens you can buy a balloon from one of the scientific surplus houses which sell them, and inflate it with your shop vac until it explodes).
What gets me is the claim that the payloads are unrecoverable. How hard could it be to equip each one with a mylar Rogallo kite and have it aim toward its ground station once the balloon bursts and lets it start gliding down? A 5:1 lift/drag ratio means a range of about 100 miles starting from 100,000 feet. What do you need to guide it, one model-airplane servo? This isn't rocket science.

LOS ANGELES (Reuters) - Actor Jim Varney, the voice of Slinky Dog in the "Toy Story" movies and the bumbling handyman Ernest in TV ads and a popular series of slapstick films, died Thursday of cancer at age 50, friends said.
Varney, who lost two-thirds of his right lung to cancer in September 1998, died before dawn at his home in Whitehouse, Tenn., outside Nashville, his spokesman and former wife, Jane Varney said.
"He passed away very peacefully," she said. "It all happened rather quickly." His death came just months after he reprised his voice role as Slinky Dog in a sequel to the 1995 computer-animated Disney hit "Toy Story."
A native of Lexington, Kentucky, Varney is best known for his role as Ernest P. Worrell, the grinning, tool-belted bumbler he has portrayed in a host of television commercials. His character always appeared opposite an off-camera, silent neighbor, whose attention he got with the line "Hey Vern!" before launching into a hard-sell.
His Ernest persona has been the star of a series of nine slapstick comedy films dating back to the '80s, including "Ernest Goes to Camp," Ernest Saves Christmas," "Ernest Goes to Jail," "Ernest Rides Again," "Ernest Goes to Africa" and "Ernest in the Army."
The Ernest character originally was created to help promote a newly opened amusement park in Bowling Green, Ky., his longtime attorney and friend, William "Hoot" Gibson, said.
His battle with cancer was first revealed publicly in November after questions were raised about his loss of hair when he was seen at public appearances in connection with "Toy Story 2."
Following his 1998 lung surgery, he suffered a bout of pneumonia, then underwent radiation treatments after cancer was detected in his brain in January 1999, Ms. Varney said. She said cancer also was believed to have spread to his spine. Friends said he had been a heavy smoker.
Still, he continued working, and "it's really been in the last three months that he was laid up, not able to get around," she said.
Varney will return posthumously to the big-screen in two upcoming films, according to his friend, Gibson.
He co-stars with Oscar-winner Billy Bob Thornton in the comedic love story "Daddy and Them," scheduled for release by Miramax Films later this year. In the film, written and directed by Thornton, Varney plays a character named Uncle Hazel, whose relatives are trying to rescue him from prison.
He also will supply the voice of a cook named Cookie in the upcoming Disney Animated Feature "Atlantis," due for release next year.

The idea is that enough commercial planes are in the air at any moment, and are spaced evenly enough, to provide coverage for much of the country. Certainly major cities would be well covered. And the nice thing is that busy travel times coincide with peak calling hours.

The concept of putting transmitters in the sky isn't new. Iridium has been doing worldwide telephone coverage by using satellites for years. The whole weather balloon receiver thing, while it's an interesting concept, sounds like it would be error prone (the coverage would be inconsistant due to weather balloons going up or down) and costly (To quote the article: "The company estimates its annual operating expenses at $35 million per year. About half of that would go toward equipment: $300 worth for each of the 50,000 or so balloons that would be launched over the course of a year.").

Is it cheaper for the phone companies to patch holes in balloons or replate a tower.

Most weather balloons actually use Helium. The volume of He in the balloon expands with increased altitude which results in cooling of the gas... No "hot air" in this one as temperatures can drop to minus 125 degrees Celsius in polar mesospheric clouds that form over the summertime polar caps. However, most WX balloons don't get much higher than the stratosphere.

Actually not quite...
The balloon flights actually only last about two hours and then the balloons break. In fact the balloon flights in question are done world wide at 0000 and 1200 UCT (Used to be GMT). They record temperature, humidty, air pressure and by triangulating from the ground tracking antenna you can calculate upper level winds.
I'm actually being generous with the length of flight. The time of year has a lot to do with the length of flight. The calculated height of the flight is related very much to the air pressure and for a flight to be valid it generally must be below 100 millibars. (The higher the balloon the lower the millibar reading). A flight reaching 3 millibars is around 120,000 ft. Summer flights usually have balloon bursts below 15 millibars. In winter early bursts, above 100 millibars, can require a second release, provided it happens within a given time window. The weather instrument package is called a radiosonde. Two types of upper air balloon a generally used for launching off the surface. For calmer winds a soft cheap latex balloon called a Kaysam is used and for adverse wind conditions or launch from a ship at sea a severe weather balloon called a Totex is used. (Totex is more rugged and more expensive)
They say they plan to hitch a ride on the existing balloons. The short duration is going to be a problem. The balloons expand as they rise and then go BOOM
I worked as an Aerological Observer for Environment Canada at a variety of Arctic Weather stations for about six years sending these suckers up there! There are long duration high altitude balloons out there, but the upper air program the article refers to doesn't use them, and the balloon shown in the photograph is of the variety to quickly put a few "holes" in the flight duration claim!

They burst and come down in rather small pieces (if you want to see what happens you can buy a balloon from one of the scientific surplus houses which sell them, and inflate it with your shop vac until it explodes).
What gets me is the claim that the payloads are unrecoverable. How hard could it be to equip each one with a mylar Rogallo kite and have it aim toward its ground station once the balloon bursts and lets it start gliding down? A 5:1 lift/drag ratio means a range of about 100 miles starting from 100,000 feet. What do you need to guide it, one model-airplane servo? This isn't rocket science.
Scientists restrict study to entire physical universe; creationist
Wouldn't a tethered balloon be a lot more effective, as well as reusable?
