Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

New projects at Sun: "Sun's Squawk project was noted by Gage. Written in Java, Squawk is intended to provide multiple virtual machines and treat an application as an object, Gage said. Squawk would provide more efficient use of memory and power, according to Gage. Squawk was described on Sun’s Web site as a compact, high-performance Java environment.  "This is perfect for wireless sensor devices," Gage said."  7:54:50 PM  permalink

Puffin Cam:  "The Project Puffin seabird camera is now beaming live-streaming video from Matinicus Rock—Maine’s largest colony of Atlantic Puffins and Razorbills. Matinicus Rock is located 22 miles south of Rockland, Maine. .. The robotic camera was funded by grants from MBNA Foundation and the Disney Wildlife Conservation Fund. The video signal is beamed by microwave 25 miles to Rockland .. When the [visitor] Center opens, visitors will be able to operate the camera. The camera is an invention of Daniel Zatz of SeeMore Wildlife Systems of Homer, Alaska.

The camera is set to move every two minutes on an auto tour of 20 preset locations that show seabird habitat on Matinicus Rock. The auto tour includes the murre attraction program that is using decoys to encourage Common Murres to nest on the island.. The camera turns on automatically at 5AM and runs until 9PM- at which time viewers will be able to see the light sending its powerful beams. .. The auto tour also includes two minutes of observation within an underground puffin burrow. Using infrared lighting, viewers will be able to see the growing chick and its parents. This is the first underground video of nesting puffins to be shown on the Internet. "

When Pigs Wi-Fi:  Free WiFi works in rural Oregon:  "this chunk of arid farm country appears to be the largest Wi-Fi hot spot in the world, with wireless high-speed Internet access available free for some 600 square miles. Most of that is in eastern Oregon, with some just across the border in southern Washington .. Morrow and Umatilla Counties in eastern Oregon are far ahead of them in providing high-speed Internet coverage to residents, schools and law enforcement officers - even though all of Morrow County doesn't even have a single traffic light. .. [WiFi] is free for consumers and has been up and running for more than a year and a half.

One reason it sprang up here is that a nearby Army depot contains chemical weapons, so there is special concern about what would happen if a cloud of nerve gas escaped from the depot. That fear helped provide a pot of federal money to underwrite safety systems.  Usually, the police and fire agencies communicate just by radio, but Hermiston decided to go with a public-private partnership that established a Wi-Fi network. .. all police officers now carry [wireless computers that] download data and receive images from video monitors - and, if nerve gas ever escaped, display the cloud's direction and speed.

Fingerprint readers are now being added to these portable devices so a police officer can almost instantly run a person's fingerprint through a multistate database. And if there's a report of a burglary, the police rushing to the scene can download floor plans of the building, live images from video monitors and information about the alarm system. ..

Hermiston is already starting to introduce WiMax, the next generation of technology after Wi-Fi, offering much higher speeds and greater range."
