1. WiFi monitor模式介绍
通常大家对于WiFi的理解主要来自无线路由器和和接入无线路器的设备，比如：笔记本电脑，手机，智能电视机，智能开关，智能电饭煲等。由于这些设备使得我们的日常生活更加便捷。 从技术的角度来说，这些智能设备都是基于IP网络在进行信息交互。说的更加专业一点就是这些设备都满足OSI（Open System Interconnection）分层设计，遵循IPv4/IPv6协议进行信息交互。 补充介绍下OSI七层模型： L7应用层：HTTP FTP TFTP SMTP SNMP DNS TELNET HTTPS POP3 DHCPL6表示层：数据的表示、安全、压缩；JPEG、ASCll、EBCDIC、加密格式等。（在五层模型里面合并到应用层）L5会话层：建立、管理、终止会话。对应主机进程，指本地主机与远程主机正在进行的会话。（在五层模型里面合并到应用层）L4传输层：TCP UDPL3网络层：ICMP IGMP IP（IPV4 IPV6）L2数据链路层：建立逻辑连接、进行硬件地址寻址、差错校验等功能。将比特组合成字节进而组合成帧，用MAC地址访问介质，错误发现但不能纠正。L1物理层：设备之间非结构化原始数据的传输和接收这里所讲述的WiFi monitor模式就是运行在L2数据链路层，从软件的角度来看就是最底层了，在下面就是与硬件寄存器相关的操作(这块内容大部分就是驱动层，硬件解决方案不同可能会有不同的差异)。 WiFi monitor就是在L2数据链路层对WiFi RF信号进行监视。 2.
