Reconfigurable Ultra-Low Power Miniaturized EVA Radio
EVA radio is an important integral part of lunar missions and beyond. To minimize power consumption and mass of an EVA radio, innovative solutions are needed for the design of various modules ranging from RF front end to networking protocols. In this protocol, a comprehensive design architecture that can achieve ultra-low power miniaturized EVA radio is proposed. Under this architecture, new MEMS-based technologies are employed to dramatically reduce the power consumption of RF front end and transceiver. By exploiting commercial wireless technologies in baseband and medium access control (MAC) modules, the EVA radio is also conformant to standard commercial wireless networks. Power consumption in baseband and MAC modules is minimized by selecting the most power-efficient design among commercial products. To further minimize power consumption during communications, power-efficient protocols across different layers are proposed. Such protocols are QoS-oriented and can support self-discovery, self-configuration, and self-healing of ad hoc networks formed by EVA radios. As an additional feature to the EVA radio, a navigation and location tracking scheme is also proposed in this proposal.
