Title: Innovations of Fangxin Xu in Wireless Communication
Introduction
Fangxin Xu is a notable inventor based in Macau, MO, recognized for his contributions to wireless communication technologies. He holds 2 patents that focus on enhancing the efficiency of wireless local area networks (WLANs). His work is instrumental in optimizing communication protocols that facilitate better data transmission.
Latest Patents
Fangxin Xu's latest patents include a "Queue-based MAC protocol with subcarrier allocation optimization." This innovative MAC protocol is designed for random access over a channel, incorporating three concurrent processes. The protocol features a contention subchannel and a transmission subchannel. During the contention process, all nodes utilize the standard RTS/CTS mechanism on the contention subchannel to vie for transmission rights. Once a node secures the right, all nodes record the contention result in their respective contention queue (CQ) buffers. In the transmission process, nodes sequentially transmit data over the transmission subchannel based on the order stored in the CQ buffers. The CQ buffers are updated as each node completes its transmission.
Another significant patent is the "Method and system for contention queuing using a queue-based MAC protocol." This protocol aims to improve throughput efficiency in WLANs. Similar to his previous patent, it includes three concurrent processes and divides the channel into contention and transmission subchannels. The contention process employs the RTS/CTS mechanism for nodes to contend for transmission rights, with results stored in CQ buffers. The transmission process follows the order of nodes in the CQ buffers, ensuring efficient data transmission.
