6 foot Helium Ballom & WRT54G Router

[KC9OIS]

Interesting video on wifi via tethered balloon. Used for "wardriving" in this application (circa 2008). They use a 6 foot tethered balloon filled with helium at 150 feet, carrying at 3.5lb payload. The basic payload consisted of a WRT54G router, a CCD camera with pan & tilt control, an omni-directional, a directional antenna and a fiber optic transceiver and a couple of 9v batteries all packaged in a small Igloo Mini-Mate cooler.

The concept could be easily adapted for HSMM for use during special events or possibly emergencies. Could provide excellent covering of 5 - 10 miles or more in urban areas
