This book was released on 2018-06-12 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: On February 14, 2002, the FCC adopted a FIRST REPORT AND ORDER, released it on April 22, 2002, and on May 16, 2002 published in the Federal Register a Final Rule, permitting marketing and operation of new products incorporating UWB technology. Wireless product developers are working to rapidly bring this versatile, powerful and expectedly inexpensive technology into numerous consumer wireless devices. Past studies addressing the potential for passenger-carried portable electronic devices (PEDs) to interfere with aircraft electronic systems suggest that UWB transmitters may pose a significant threat to aircraft communication and navigation radio receivers. NASA, United Airlines and Eagles Wings Incorporated have performed preliminary testing that clearly shows the potential for handheld UWB transmitters to cause cockpit failure indications for the air traffic control radio beacon system (ATCRBS), blanking of aircraft on the traffic alert and collision avoidance system (TCAS) displays, and cause erratic motion and failure of instrument landing system (ILS) localizer and glideslope pointers on the pilot horizontal situation and attitude director displays. This report provides details of the preliminary testing and recommends further assessment of aircraft systems for susceptibility to UWB electromagnetic interference.Ely, Jay J. and Shaver, Timothy W. and Fuller, Gerald L.Langley Research CenterELECTROMAGNETIC INTERFERENCE; AIRCRAFT COMMUNICATION; COLLISION AVOIDANCE; FAILURE; RADAR BEACONS; RADIO BEACONS; AIRLINE OPERATIONS; ATTITUDE INDICATORS; CIVIL AVIATION; COMMERCIAL AIRCRAFT; INSTRUMENT LANDING SYSTEMS; RADIO RECEIVERS; WARNING SYSTEMS

Download or read book Design of Ultra Low Power Impulse Radios written by Alyssa Apsel and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the fundamental principles behind the design of ultra-low power radios and how they can form networks to facilitate a variety of applications within healthcare and environmental monitoring, since they may operate for years off a small battery or even harvest energy from the environment. These radios are distinct from conventional radios in that they must operate with very constrained resources and low overhead. This book provides a thorough discussion of the challenges associated with designing radios with such constrained resources, as well as fundamental design concepts and practical approaches to implementing working designs. Coverage includes integrated circuit design, timing and control considerations, fundamental theory behind low power and time domain operation, and network/communication protocol considerations.
