The output power of transmitter in wireless applications should be adjusted dynamically with the change of environments to implement the power management. In this paper, a two-way power management algorithm based on real-time path loss of propagation channel was implemented and validated in a point-to-point wireless system worked at 2.45 GHz. The performance of the power management was testified and...
We propose a Zigbee technology based wireless vehicle identification and driver authentication system consisting of a central database of authorized vehicles, Zigbee RF Vehicle tags, RF tag Reader and RF tag Writer. Zigbee is based on IEEE 802.15.4 standard for Wireless Personal Area Networks (WPANs) that is being used in many commercial and research applications today where it has become an attractive...
