Design and implementation of sub-GHz wireless light switch with integrated Wi-Fi

This paper presents the development of wireless light switch system with primary signal carrier band in Sub- GHz. In contrast to conventional wired lighting system, wireless concept delivers much more efficient application in material budget, distance, simplicity and performance. At the other side, application may be better performed with Wi-Fi network of 2.4GHz in terms of worldwide popularity, however, 2.4GHz has more complicated protocol stack and limitation of power consumption as well as high traffic congestion. With the application of Sub-GHz band, these difficulties can be completely avoided, especially for the application of light switch system. Therefore this project implements the upsides of both frequency bands and protocols by integrating both of them in impressive way to achieve the excellence in product efficiency and performance.
