Abstract (in Japanese) (See Japanese page) 
(in English) Wireless LANs (WLANs) have already spread to provide the Internet connectivity for end nodes, while long-distance WLANs are attracting as a new solution for backbone networks to remote rural areas.
Some long-distance WLAN projects have evaluated communication quality and characteristics oftheir own long-distance WLANs.
However, their reports didn't show the essential basic characteristics for constructing long-distance WLANs.
In this paper, we actually construct a long-distance WLAN with three types of antennas and evaluate communication quality and basic characteristics of them with changing distance between antennas and angle of an antenna.
In our experiments, we employ real-time and non real-time applications, and investigate the following five performance metrics: RSSI, frame retransmission, packet loss, RTT and throughput.
Through the experimental results, we discuss useful performance metrics for constructing long-distance WLANs satisfying application requirements.
