Welcome to Smart Wireless Laboratory

Due to drastic increase of mobile communication devices, broadband wireless communication systems are becoming demanded. Furthermore, the scarcity of frequency spectrum results in the necessity to enhance the application of broadband communication systems.

Smart Wireless Laboratory is working on research and development on using: (1) unused frequency of Millimeter­wave and Tera­Hertz wave, (2) frequency for wide area communications such as the VHF band, which are not allocated for broadband communications purposes previously, and (3) unused frequency (white space) for particular purposes.
We are also conducting research and development on super long life devices with the latest frequency control technology, low consumption power and interference reduction techniques.
