Andrew Automates San Francisco's AirTrain System.ORLAND PARK Or·land Park A village of northeast Illinois, a residential and manufacturing suburb of Chicago. Population: 53,300. , Ill.--(BUSINESS WIRE)--Nov. 16, 1998-- San Francisco's new AirTrain will use an Andrew Corporation designed, manufactured, and installed distributed communications system In telecommunication, a communications system is a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment (DTE) usually capable of interconnection and interoperation to form an integrated whole. for RF-based train control Andrew Corporation Andrew Corporation is an American multinational producer of communications devices. Andrew is a global designer, manufacturer, and supplier of communications equipment, services, and systems. will design and supply the distributed communications system for an RF-based train control system for San Francisco San Francisco (săn frănsĭs`kō), city (1990 pop. 723,959), coextensive with San Francisco co., W Calif., on the tip of a peninsula between the Pacific Ocean and San Francisco Bay, which are connected by the strait known as the Golden Airport's people mover people mover n. A means of mass transit, such as a moving sidewalk or a monorail, used to transport people, usually along a fixed route. people mover Noun Brit, Austral & NZ same as system. The AirTrain system will transfer airport employees, airline passengers, and visitors between airport terminals, parking, and other facilities. The RF-based automatic train control system uses 2400 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. spread spectrum radios to provide contactless radio transmission links between the trains and the wayside. Positioning and operational communications are all controlled through the wireless links. This operation represents a technical breakthrough in rail signaling control which has traditionally relied on track contact to sense train position and more recently used low frequency inductive communications techniques. When completed, AirTrain will have three miles of elevated double guideway in two independent loops, and a projected capacity of 4,000 passengers per hour. Under the contract, signed in June 1998, Andrew is working with operating system contractor Adtranz, a Pennsylvania-based division of ABB n. 1. Among weavers, yarn for the warp. Hence, Noun 1. ABB - an urban hit squad and guerrilla group of the Communist Party in the Philippines; formed in the 1980s Daimler-Benz Transportation, to design, develop, and install the distributed communications system. The RF-based train control system will use 24 spread spectrum mobile radios, four spread spectrum base radios, and 15 in-line amplifiers, all connected by RADIAX(R) radiating cable. The Andrew portion of the AirTrain project is due for completion in October 2001. "This contract is significant for Andrew and the mass transit industry in general," said Joel Holyoak, director, Andrew Wireless Communications R&D. "It represents the first installation in North America of a communications-based train control system utilizing 2400 MHz spread spectrum technology." Product Information Andrew 2400 Spread Spectrum Radios - provide reliable data communications for the communications-based train control industry. Their ruggedized design withstands the handling and severe conditions found in the mass transit industry and ensures high reliability. The model 2400 incorporates a full duplex communications channel to maximize access to all trains. This enables maximum data throughput and maintains the necessary system response requirements of the train control system. In its MOBILE configuration the 2400 Spread Spectrum Radio's design withstands the type of adverse conditions that exist in the metro train environment. The unit is housed in a NEMA-4 (National Electrical Manufacturers Association This article is about the standards association NEMA. For other uses, see Nema. The National Electrical Manufacturers Association or NEMA is a U.S. ) weatherproof enclosure, ready for custom installation. The 2400 BASE STATION radio configuration incorporates the same electrical features as the mobile unit. Housed in a 19-inch rack mount enclosure or in a weatherproof NEMA-4 enclosure, it can easily be mounted on an outdoor pole or structure.

The in-line amplifiers are designed to operate in a busy mass transit system environment where reliability is crucial. Modular construction techniques are used throughout the design to facilitate ease of maintenance and repair. RADIAX(R) RCT6-3 radiating cable - This new cable is specifically suited for PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. , DCS-1800, and other applications in the 1700-2500 MHz frequency range. It offers improved RF link performance compared to conventional wideband radiating cables. The benefits of RADIAX RCT6-3 cable include its ability to pass broadband channels (spread spectrum, video, high rate data) and its requirement for lower margins for high probability communications. This cable is suitable for tunnels and metros. About AirTrain San Francisco's AirTrain system will include nine stops throughout the San Francisco International Airport “SFO” redirects here. For other uses, see SFO (disambiguation). For the television series, see . . AirTrain will enable fast easy travel between airport terminals, parking lots, the new Rental Car Center, and a new airport hotel. The system will use automated, non- polluting, energy efficient, electric trains on rubber tires. AirTrain's free train transportation service will reduce San Francisco Airport roadway traffic by 23% and eliminate half of all commercial vehicle trips to and from terminal roadways. The AirTrain system is designed to accommodate airport and passenger growth with the use of additional trains. In Fiscal Year ending June 30, 1997 the San Francisco International Airport had 39,703,093 passengers. Estimated passenger numbers for AirTrain are 4,000 per hour. The projected opening date for the system is December 2001.
