Abstract

A switch device by using a Wireless Local Network Media Access Control(MAC) protocol, including: a wired network interface, a wireless network interface, a memory element and a operation device, it exchange signals with wired network by using wired network interface, in the mean time, it exchange signals with outside another wireless network work stations utilize wireless network interface and communicating by wireless communication method, by this way, it let said switch device became an Access Point(AP) between wired network work stations and wireless network work stations; the specialty is to set a Channel Using Table and a Multi-Channel Transmission Mode Table in said memory element, by this way, we can record all transmission situations among all wireless network work stations, all using channels and channel release time, further more, providing control packets to related work stations (including the information of using channels and time), then it will switch from a common channel to an assigned data channel and operating data parallel transmission in setting time period. Based on said switch device and said switch method, we can double the wireless bandwidth among all wireless network work stations, saving data transmission time and producing more parallel throughput.
