摘要：
In recent years, the needs for wireless communication have risen rapidly due to the need to build free and intelligent communication systems on OA, FA, etc. Responding to these needs, the radio law was revised in December of 1992, and the use of non licence low power data communication systems with the spread-spectrum technique at 2.4 GHz became possible. We have developed a 2.4 GHz low power data communication system with antennas. This paper describes its wireless scheme, circuit constitution, basic specifications and in particular the characteristics of its RF unit and omni-directional printed antenna. We have also developed a wireless POS system as one application of the systems.
