Abstract:With the rapid development of mobile devices, the requirement of wireless network speed and quality for industrial applications is getting higher and higher. However, the development of wireless network is slow and far from meeting the actual needs. Therefore, in view of the bottleneck problem of wireless network transmission speed and quality, this study proposes a parallel gateway using multi-channel wireless transmission. The system uses a pair of parallel gateways to establish a multi-channel wireless connection to realize the parallel transmission of Ethernet frame data, so as to improve the transmission speed of wireless networks. Moreover, UDT transmission protocol is used for data transmission between parallel gateways to improve the quality of data transmission.
