Abstract

A wireless tag system, in which an infrared (IR) beam and an electromagnetic wave with a radio frequency (RF) are used, has been developed for maintenance and management of outdoor communication facilities. The system was constructed using IR-RF tags, an IR commander and an RF receiver. The IR command radiation with strong directivity and the RF response without directivity enable, respectively, a facility management system to recognize a target facility and to obtain data from within a large circular area. Solar and secondary batteries are also adopted for the power module in the system to allow easy maintenance at long intervals. IR and RF signal communication is possible up to a distance of 9 m and within a circle with a radius of approximately 9 m, respectively.
