| Abstract(in English) | The fundamental performances of an IP-based ultrahigh-speed wireless LAN prototype were measured. This prototype is a centralized LAN using two waves in the 60-GHz band for providing a radio transmission speed of 128 Mbps for two-way communication. It employs a media-access-control(MAC) protocol based on reservation-based slotted idle signal multiple access(RS-ISMA) for sharing the radio links among multiple users. We connected one access point to one user-station with baseband interface, and measured the throughput, average latency, and latency distribution of Ethernet frames. The measurement showed that the prototype LAN provides the maximum throughput of 30 Mbps, and that the measured throughput agrees with the theoretically predicted one. It also showed that the maximum latency, which includes switching and routing latency in the wired part, is below 1 micro sec.Isochronous polling mode, which was designed for time-bounded real-time applications, provides lower variance in throughput than asynchronous mode, which was found to make its best efforts to increase its throughput by dynamically using unassigned slots for data applications. |
