Abstract
Provided are methods and systems for multiband wireless data transmission between aircraft and ground systems. The transmission uses different wavelength ranges, each wavelength range corresponding to a different data domain and establishing a different communication channel. This wavelength differentiation provides physical separation between different data domains and, as a result, improves data security. Furthermore, a single broadband antenna is used on the exterior of the aircraft for transmitting data sets from different data domains. The single antenna configuration reduces drag and weight and improves structural integrity of the aircraft in comparison to multi-antenna configurations. Different aircraft communication modules, which are connected to different aircraft systems, handle different data domains and operate at different wavelength ranges. These modules are connected to the same antenna using a multiplexer. This connection may be controlled using gate devices and may be conditioned on verification of communication channel availability, security status, and other factors.
