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.

Philly considers wireless Internet for all: "For about $10 million [to install and $1.5m/yr to operate], city officials believe they can turn all 135 square miles of Philadelphia into the world's largest wireless Internet hot spot.  The ambitious plan, now in the works, would involve placing hundreds, or maybe thousands of small transmitters around the city, probably atop lampposts. Each would be capable of communicating with the wireless networking cards that now come standard with many computers. Once complete, the network would deliver broadband Internet almost anywhere radio waves can travel, including poor neighborhoods where high-speed Internet access is now rare. And the city would likely offer the service either for free, or at costs far lower than the $35 to $60 a month charged by commercial providers..  [Similar efforts include:]

  • Chaska, Minn., a suburb of Minneapolis, began offering citywide wireless Internet access this year for $16 a month. The signal covers about 13 square miles.
  • Corpus Christi, Texas, has been experimenting with a system covering 20 square miles that would be used (for now) only by government employees.
  • Over the past year, Cleveland has added some 4,000 wireless transmitters in its University Circle, Midtown and lakefront districts. The service is free, and available to anyone who passes through the areas.  Some 1,016 people were logged in to the system at 2:20 Tuesday afternoon, said Lev Gonick, chief information officer at Case Western Reserve University, which is spearheading the project and paying for a chunk of it. "We like to say it should be like the air you breathe, free and available everywhere," Gonick said. "We look at this like PBS or NPR. It should be a public resource."
  • In New York, city officials are negotiating to sell wireless carriers space on 18,000 lampposts for as much as $21.6 million annually. T-Mobile USA Inc., Nextel Partners Inc., IDT Corp. and three other wireless carriers want the equipment to increase their networks' capacity.

One part of the 15-year deal is cheap Wi-Fi phones for neighborhoods where less than 95 percent of residents have home phones. IDT, which has agreed to market the cheaper phone service in those neighborhoods, would pay lower rates for poles there than other companies would in wealthier areas. .."
