Classification: CPC H  B | IPC B  H

Claim 9:
10. A system for communication to an access point of an avionics network, the system comprising:
a host device including a host chassis and a host circuit card assembly fixed to the host chassis, the host circuit card assembly receiving aircraft electrical power;
an expansion card including an edge connector, a real-time-clock, a radio-frequency module, and a first coaxial radio frequency connector, wherein the radio frequency module is configured to generate a modulated radio frequency signal, wherein the modulated radio frequency signal is output by way of the first coaxial radio frequency connector;
a coaxial cable; and
a circuit card assembly including:
a circuit card including a first side, a second side opposite to the first side, and a plurality of mounting holes by which the circuit card is mounted to the host chassis;
a first interface disposed on the first side of the circuit card for receiving power from the host circuit card assembly;
a second interface disposed on the first side of the circuit card for receiving the edge connector of the expansion card, wherein the power is continually provided to the second interface for powering the real-time clock;
a second coaxial radio frequency connector disposed on the first side of the circuit card, wherein the first coaxial radio frequency connector and the second coaxial radio frequency connector are coupled by the coaxial cable such that the second coaxial radio frequency connector receives the modulated radio frequency signal from the radio-frequency module; and
an antenna disposed on the second side of the circuit card and communicatively coupled to the second coaxial radio frequency connector, the antenna transmitting radio waves based on the modulated radio frequency signal.
