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.

Brazil delays payment to Raytheon for jungle radars: "The decision by Brazil's government came after delays in the development of a very high frequency (VHF) radio system by Raytheon to serve the $1.4 billion system that monitors drug runners, loggers, and other illegal activities in the Amazon...

It was not clear how this would hinder the full functioning of Sivam, the vast majority of which is already up and running. The Air Force spokesman said that for now personnel were using inferior technology radios. The largest system of its kind in the world, it combines radars, control centers, and aircraft with sensors to create a surveillance web that can monitor illegal deforestation to incursions by unidentified aircraft into Brazil's Amazon.

Raytheon is developing a new radio system which would be especially adapted to the jungle conditions of the Amazon. Perlini said final tests of the radio system would now take place in the first quarter of next year and be fully operational in the second quarter. The Air Force spokesman said only 19 of the 27 radios were currently in place at jungle command centers, which would ultimately improve contact with monitoring aircraft. Perlini said the VHF system was the final part of a huge monitoring system. "It is one part of a very large and complex system," she said. "You know the Amazon is two-thirds the size of the U.S. and you have less roads than in the state of Maine; that adds to the complexity." "
