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." " 12:39:12 AM
Drawing PC, TV and Stereo Into an Entertainment Loop: Review of wifi links to TVs and stereos. Key points:
- all do pictures and audio ok
- 802.11b has problems with video streaming, 802.11g should be ok
- equipment reviewed:
- Linksys WMA11B Wireless Digital Media Adapter (about $150)
- Hewlett-Packard ew5000 Wireless Digital Media Receiver ($200)
- Prismiq Media Player ($250), with optional $50 wireless keyboard for surfing the web on the TV and $70 802.11g upgrade PC card. With TV picture-in-picture, you can type chat into a window while watching TV
- Gateway's Connected DVD Player ($200)
- Service upgrades from Tivo and Microsoft XBox
- the author used a Microsoft MN-700 802.11g Wireless Base Station ($89), noting other wireless "g" routers from Netgear and Linksys
- "All the devices I tested, except the Linksys Media Adapter, forced me to give up some network security to make the wireless hookup work.
- none played all the popular computer music, photo and video file formats. Apple's AAC music files, for example, were not supported by any of the devices, few can play video file formats like Real that are commonplace on computers."
