The term beaconing refers to the periodic transmission of "broadcast" frames on a pre-determined channel sequence. Broadcast in this sense means that these frames are sent to the broadcast destination address and not to a specific destination MAC address. These beacon frames may be used to convey timing and routing information and also serve as a form of "broadcast" in a wireless mesh network. Any node that knows the beacon channel sequence and tinning may listen to the beacon transmission from a transmitting node. Known ad hoc wireless networks may employ "beacons" as a way in which network nodes may perform neighbor discovery (i.e., locate other nearby nodes) and advertise routing information. A beacon is a transmission that may be generated by one node and received by some or all of the nodes within a transmission range. All or fewer than all of the nodes in a network may be capable of beaconing.
短距离范围内设备之间的连接与通信网络，称之为WPAN (Wireless Personal Area Network，无线个人域网络)。WPAN是指个人范围 (即短距 离范围) 内的设备所组成的网络，是一种与广域网、局域网并列但是范围较小的无线网络。[...] WPAN可以构建为两种以不同方式通信的网络，一种称为信标网络，另一种称为非信标网络。在信标网络内，设备以信标方式通信。其通信方式为：每个作为协调者的设备与一定数量的作为非协调者的设备通信；协调者可以周期性地以各自的周期发送信标，信标中可以定义该协调者的超帧结构；作为非协调者的设备通过监听该协调者的信标与该协调者同步，并利用该信标中的超帧参数与发送信标的协调者通信。
