Description
本申请涉及无线通信领域,尤其涉及一种发现和连接到软接入设备的方法、装置、设备及存储介质。
802.11be网络,也称为Extremely High Throughput(EHT)网络,通过一系列***特性和多种机制增强功能以实现极高的吞吐量。随着无线局域网(WLAN)的使用持续增长,对于在许多环境(例如家庭,企业和热点)中提供无线数据服务越来越重要。特别是,视频流量将继续是许多WLAN部署中的主要流量类型。由于出现了4k和8k视频(20Gbps的未压缩速率),这些应用的吞吐量要求正在不断发展。诸如虚拟现实或增强现实、游戏、远程办公室和云计算之类的新型高吞吐量,低延迟应用程序将会激增(例如,实时游戏的延迟低于5毫秒)。
鉴于这些应用程序的高吞吐量和严格的实时延迟要求,用户期望通过WLAN支持其应用程序时,吞吐量更高,可靠性更高,延迟和抖动更少,电源效率更高。用户期望改进与时敏网络(TSN)的集成,以支持异构以太网和无线LAN上的应用程序。802.11be网络旨在通过进一步提高总吞吐量和降低延迟来确保WLAN的竞争力,同时确保与旧版技术标准向后兼容和共存。在2.4GHz,5GHz和6GHz频段运行的802.11兼容设备。
