In order to increase area spectral efficiency by exploiting unused spectral resources scattering in multiple frequency bands, we have been studying a wireless LAN (WLAN) system which simultaneously transmits multiple wireless frames over multiple frequency bands such as 2.4 GHz and 5 GHz, and we developed its initial hardware prototype. This paper introduces our developed prototype, and fundamental experiment to validate the effectiveness of our proposed multi-band WLAN. Evaluation results show that simultaneous multi-band transmission technique improves a throughput performance by about 2.5 times compared with conventional single-band transmission under the crowded channel condition.
