摘要
协议命名为802.11be的Wi-Fi 7是IEEE 802.11系列的最新版本,因其引入多链路、4096QAM调制及多AP协作等创新技术,Wi-Fi 7拥有更快的速度、更低的延迟、更大的容量和更好的能效,可很好满足下一代无线局域网对极高吞吐量和极低时延业务的应用需求。同时,由于Wi-Fi 7增加了6 GHz频段和新的带宽模式,拥有丰富的无线信道资源,从而大大减少了设备间干扰,提高了网络的稳定性和可靠性,扩展了其在未来的应用场景。首先对Wi-Fi 7的核心技术进行研究,其次结合其技术特点对其未来可能的发展应用进行探讨。
As the latest version of IEEE 802.11 series,Wi-Fi 7,protocol named 802.11be,introduces innovative technologies such as multi-link,4096QAM modulation and multi-AP collaboration,enabling Wi-Fi 7 to have faster speed,lower latency,larger capacity and better energy efficiency,which can well meet the application requirements of the next-generation WLANs for extremely high throughput and low-latency services.At the same time,due to the addition of the 6GHz frequency band and the new bandwidth mode,it has rich wireless channel resources,thus greatly reducing the interference between devices,improving the stability and reliability of the network,and expanding its application scenarios in the future.This paper first investigates the main core technologies of Wi-Fi 7,and then discusses its possible future development and application with its technical characteristics.
