09 Jul 12. W. L. Gore & Associates has developed new cable-based antennas (often referred to as leaky lines or leaky feeders) that improve signal propagation without increasing the amount of hardware required on an airplane. Ideal for both wide-body and single-aisle passenger aircraft, GORE® Cable-Based Antennas provide reliable access to different wireless protocols so passengers can easily connect to in-flight entertainment, Internet servers, and email accounts. GORE® Cable-Based Antennas are easily installed along the length of the cabin ceiling, and with signal propagation occurring every meter along the antenna, passengers are assured reliable access, regardless of their location in the plane. Passengers’ signals are transmitted via a signal network computer and outside antenna to satellites that connect to the worldwide network. Unlike typical broadband technology that requires separate hardware for each type of wireless access, the versatile GORE® Cable-Based Antenna reduces airline costs because the antenna requires only one set of hardware to service the entire aircraft, regardless of its size. This lightweight antenna offers a single solution for providing connectivity for a variety of electronic devices. This antenna sends and receives signals in frequencies ranging from 400 megahertz to 6 gigahertz, which makes it compatible with numerous communication standards, including Bluetooth, DECT, DECT2, Global Star, GSM, IRIDIUM Sat, MMS, PDC, TETRA, UMTS, WLAN 802.11 a/b/g, and WiMAX. Constructed with unique, engineered fluoropolymers in a lightweight coaxial cable, the GORE® Cable-Based Antenna meets all shock, vibration and fire specifications, including AirBus ABD0031 and FAR Part 25.1359(d). Available in lengths of more than 65 meters, they require no maintenance for the lifetime of the aircraft.
10 Jul 12. SELEX Elsag, a Finmeccanica company, is to provide Boeing Defense, Space and Security with SRT270 High-Frequency radio communication systems to equip new CH-47 transport helicopters in the
Mark (MK)-6 version, recently purchased by the British Ministry of Defense. The system will feature next-generation ALE (Automatic Link Establishment) capability, the international standard which allows rapid and reliable HF radio communications. SELEX Elsag already supplied the previous CH-47 MK-2A version with HF ALE1G avionic systems. The SRT-270 is the outcome of advanced research and development activity carried out by SELEX Elsag within the High-Frequency sector. It provides voice/data radio communications for avionic applications, across the 2MHz and 30MHz frequency range. It also features high power transmission, of up to 200 Watt PEP/100 Watt AVG. The equipment encompasses the control panel, which provides a user-friendly man-machine interface through an LCD display – compatible with night scopes – to a “loop” antenna, which, combined with the ATU (Antenna Tuning Unit), ensures effective communications on the whole HF range.
11 Jul 12. Cobham NetNodeIS – The Safe Path For Critical Communications. The NetNodeIS, Intrinsically Safe, is the latest adaptation of Cobham’s world-leading COFDM (Coded Orthogonal Frequency Division Multiplexing) wireless communications product range. Developed specifically for deployment in underground coal mines, the system can remain active and uninterrupted even when an explosive atmosphere has been detected, leading to improved production efficiency and miner safety. The design of the NetNodeIS is based on proven Cobham COFDM technology currently used in demanding environments by military, government and broadcast organisations worldwide. The wireless mesh system is now offered with the European ATEX and the International IEC Ex M1 certifications, ensuring its intrinsically safe design and build quality. These standards permit its use in underground c
