Permanent link to this version: Abstract-In-flight broadband connectivity (IFBC) is a significant open market for mobile network operators considering more than 3.3 billion passengers being served by airlines in 2015. On-board broadband services are provided via air-to-ground (A2G) connectivity through direct A2G communications (DA2GC) and satellite A2G communications (SA2GC). Available on-board connectivity systems have significant limitations: high latency in SA2GC and low capacity in DA2GC. The customer expectancy is multi-Mbps connections in every seat which leads to capacity requirements of Gbps to the aircraft. Creation of high capacity IFBC requires a collaborative interaction between different industrial partners. For this reason, we investigate A2G architectures in terms of economic and technical perspectives, and propose business models by identifying new roles and positioning them in the A2G business ecosystem. In addition, we provide an extensive summary of the state-of-the-art and future improvements for A2G communications.
In order to decrease the interference to the avionics equipments from the Mobile Communications on Aircraft (MCA) deployed in cabin, multiple Access Points (AP) are expected to be installed to reduce the necessary transmission power. Due to the tunnel-shape of the cabin, the multiple APs are connected on the fiber and can provide transmission diversity. In this letter, the optimal AP deployment scheme is proposed, which is confirmed with Finite-Difference Time-Domain (FDTD) method for the wireless propagation between users and APs. Not only the interference is mitigated, but also the capacity is increased.
Mobile Communications on Aircraft(MCA) -Onboard network utilizes the 2G/3G picocell and traditional AP -AeroMobile,OnAir • FiWi (Fiber-Wireless) : a suitable technology for MCA -It can increase the capacity and mitigate fading of multipath.
