Wireless local area network (LAN) techniques have been adopted not only to office and home networks but also spot access in public places. Although the transmission speed of wireless LANs has reached to a few ten Mbps, the effective transmission speed for each user degrades due to the restriction of radio resources in multi-user environments. In this paper, we propose a new radio resource management algorithm for the IEEE802.11a wireless LAN. In the proposed scheme, the wireless transmission mode is chosen according to the acceptable bit error rate (BER) of each transmitted packet. Then, the bandwidth assignment is performed, as matching the bit rates required of the packets. The proposed scheme can improve the quality of service for every user by assigning a lot of radio resources to error-sensitive data and the data requiring high bit-rates. In this paper, we verify the availability of the proposed scheme by computer simulations.
