This article discusses some key recent developments in the area of wireless networking in the aviation industry.
New techniques and technologies in wireless communication are needed for safe and efficient aviation operations. To keep track of airplanes, pilots use high-frequency radio signals to communicate with ground controllers and other aircraft. The aircraft in low-altitude airspace plays a key role in this network, for prospects such as emergency communication, routing patrol and wireless data relay.
Role of wireless technology in aviation
Wireless technologies and networks are playing an important role in aviation at a growing pace. Commercial adoption and technological advancements are pushing the entire industry forward. Every aspect from core technology to the fundamentals of certification and safety are under consideration. National Aeronautics and Space Administration (NASA) is working to improve hyper-spectral communications, networking and air traffic control for efficient and safe future flights.
Earle Olson, vice president, Airborne Wireless Network, says, “Wireless communication for aviation, traditionally, has been relegated to weather and flight information. Beyond this, there have been additional applications related to in-flight entertainment. This area has been supported by ground-to-air and sat-com applications as well as wireless access points onboard aircraft.”
He adds, “Airborne Wireless Network is developing a high-performance communications system to provide a wholesale airborne wireless broadband service to provide service on a global basis, utilising commercial aircraft as part of its global airborne mesh network. This is a path-breaking technology that has the potential to augment connectivity to the underserved regions of the world and improve connectivity for all. By virtue of the system being onboard commercial aircraft, its system could also support in-flight entertainment companies with a provision and drastically improve the Wi-Fi provider’s service quality and overall passenger experience.”

Other and the primary military application is Link-16.
It provides a high speed and secures communication and certainly all these functions which are provided by AWACS and Link-16 are enabled with quite rigid military standards.
Briefly, in commercial aviation, satellite-based broadband communication for all phases of flight can be primarily intended for exchanging information in-flight which allows much greater volumes and higher speed of data than transmitted over ACARS. Thus, new generation aircraft will require an environment which enables communication with airline ground systems and other aircraft reliably, transparently, and securely. In other words, it will require the systems which have encryption capabilities improved for ad hoc wireless network and new generation commercial-off-the-shelf (COTS) equipment designed based on satellite broadband communication with authorization by third parties.
That means, this sophisticated technology poses major challenges but if all parties analyze potential requirements and retrofit in existing systems from now on, new generation aircraft will be smarter and bring lots of benefit for next 15 years or less...
