Despite the unique capability of 60-GHz technology to offer a multi-gigabit rate and a huge unlicensed bandwidth (up to 7 GHz), a number of technical challenges need to be overcome before its full deployment. The system performance of capacity, coverage, and throughput need to be well understood. All of these are based on characterizing the propagation channel and establishing realistic channel mo...Show More
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 a...Show More
RFID systems are an important technique in short range wireless communication. This study explores link budget and performance limitations of microwave passive RFID system. Site-specific model and statistical model are proposed for mean path loss. The key parameters affecting the performance are studied, including reader limitations, tag limitations, multi-path propagation environments, and antenn...Show More
Power control is a significant mechanism to improve the wireless system performance and reduce the interference in indoor radio transmission environments. In this paper, a two-way power control algorithm is applied to point-to-point indoor line-of-sight (LOS) short-range radio transmission and varies the transmitted power as a function of the path gain. The effectiveness of the algorithm is verifi...Show More
