Abstract :
Mobile computing devices require reliable wireless communication links, whereby data rates, transmission range, and power consumption fit the particular needs of the various types of devices. Proper designs of physical layer functions and medium access control mechanisms are crucial for efficient connectivity and coexistence among all participants in a communication cell. We describe a solution for reliable wireless infrared connectivity based on infrared channel reciprocity. Robust header signalling, and variable data rate coding
