Abstract :
We propose a new 5/25-GHz dual-band wireless LAN for high-capacity broadband communications. In Japan, the 25/27-GHz band has been allocated for nomadic wireless access systems to increase system capacity and achieve transmission rates higher than 100 Mbit/s. We will describe the application areas and regulatory requirements of 25/27-GHz band systems, and then describe the concept of 5/25-GHz dual-band OFDM-based wireless LAN systems. We will examine the transmission performance of 25-GHz OFDM-based systems on the basis of our experimental results. We will then discuss a prototype 5/25-GHz dual-band WLAN card and demonstrate the feasibility of compact mobile terminals
