Embodiment Construction

[0022] The specific implementation manner of the present invention will be described in detail in conjunction with the summary of the invention and the accompanying drawings.

[0023] An airborne wireless network data convergence device is composed of a chassis, a main controller module and several WIFI wireless convergence modules, such as figure 1 shown. Wherein, the chassis includes a power conversion module, a filter energy storage module and a backplane bus. The main controller module communicates with multiple WIFI aggregation modules through the backplane bus for data and instructions. Among them, the WIFI aggregation module is responsible for communicating with the wireless subnet aggregation node, receiving subnet data, and forwarding control commands and configuration requirements to the subnet.
