CSI Wireless' Vector Sensor Helped NBC News Transmit Especially Vivid TV Reports from War in Iraq Vector heading system precisely aligned truck-mounted satellite dish to achieve on-the-run video transmissions that featured unparalleled clarity and immediacy for television viewers back home CALGARY, Alberta - July 21, 2003 - (TSX:CSY): CSI Wireless Inc. is looking for more technical challenges for the company's Vector Sensor GPS product, after the innovative heading system helped NBC News broadcast images from the war in Iraq that featured greater clarity and immediacy than what competing networks achieved using more conventional methods. The Vector Sensor was an integral part of a new mobile satellite transmission system that Maritime Telecommunications Network (MTN), which provides global communication systems to the maritime industry, developed exclusively for NBC to transmit news footage from Iraq during the war last March and April. To send their war reports to television viewers back home, NBC and other foreign news teams in Iraq relied on special video phones and/or dish-shaped antennas that sent video signals up to satellites, which directed the signals back to the news teams' home countries. Video phones' narrow bandwidth resulted in relatively grainy television images, while satellite dishes' much broader bandwidth resulted in much clearer images. The dishes were mounted on trucks, rooftops or towers. Traditionally, to transmit video to a satellite from a mobile truck, a news team must bring its vehicle to a full stop, set up transmission equipment, then wait for the satellite dish to achieve an accurate heading or "fix" on the satellite. While the vehicle is stopped, the war continues. In Iraq, where U.S. and British troops advanced across the desert at unprecedented speeds, news teams that stopped to transmit their video footage were constantly falling behind and then racing to catch up. However the Vector Sensor, in conjunction with the rest of the video transmission system developed by MTN, enabled an NBC satellite dish to achieve extremely accurate headings - and to transmit crystal-clear video - while the transmission truck was "on the run" or still moving. "Other networks had to stop, set up their equipment and broadcast while the news was moving away from them. NBC never had to play catch-up. They were always close to the action," said Jake Kooser, an MTN technical services specialist assigned to NBC's special mobile transmission system in Iraq throughout the war. "We were glad to have a Vector Sensor on board. It really did the job for us." Stacy Brady, NBC's Vice President, Network News Operations, said: "We were the only television network covering the war that was able to transmit 'live' from a moving vehicle, which was a coup for us. It enabled us to stay with the action all the time. We're very pleased with how our mobile satellite transmission system performed in Iraq, in very challenging conditions. We congratulate CSI Wireless for its Vector system that made 'on the run' transmissions possible." "People all over the world were eager to have a very clear picture - literally and figuratively - of the war in Iraq," said CSI Wireless President and CEO Stephen Verhoeff. "NBC News went the extra mile to provide that very clear picture, and we at CSI Wireless are pleased to know our Vector Sensor played an important part in that." About the Vector Sensor The Vector Sensor uses a sophisticated moving-base-station Real-Time Kinematic (RTK) technique to achieve heading accuracies of 0.15 degrees or better. It combines two GPS receivers in a single enclosure, and two antennas in two separate enclosures. By increasing the distance between the antennas, users can increase the Vector Sensor's heading accuracy. The Sensor is designed for the "machine control" market, including agriculture, heavy construction equipment, mining equipment, cranes and other machinery or industries for which very accurate headings are essential. CSI Wireless also offers the Vector PRO for marine heading applications. About Maritime Telecommunications Network Maritime Telecommunications Network, Inc.
