Beacon request是指由一个设备发送给协调器的一种请求帧,用于请求协调器发送beacon帧。beacon帧是一种特殊的帧,只能由协调器发送,用于通告网络信息,以便其他设备加入网络或者了解网络的情况,并且可以用于维护网络通信的同步。当一个设备想要加入一个网络时,它可以发送beacon request请求协调器发送beacon帧,以便了解网络的情况并加入网络。在ZigBee网络中,beacon request帧的格式包括帧控制字段、目标地址字段、源地址字段、帧序号字段和命令字段等。

beacon simulator
A beacon simulator is a software or hardware device that can simulate the behavior of a beacon. Beacons are small devices that transmit signals to nearby devices, such as smartphones, using Bluetooth Low Energy (BLE) or other wireless technologies. These signals can be used to determine the location of the device and trigger specific actions or notifications.
A beacon simulator can be used to test the functionality of apps or devices that rely on beacon signals without the need for physical beacons. This can be particularly useful for developers who are creating apps or devices that interact with beacons, as it allows them to test their functionality in a controlled environment before deploying them in the real world.
Beacon simulators can also be used for training purposes, such as teaching people how to use beacon-based navigation systems or testing the effectiveness of different beacon configurations.
beacon interval
Beacon interval是无线网络中的一个参数,指的是两个连续的信标帧(beacon frame)之间的时间间隔。信标帧是由接入点(access point)定期广播的一种特殊帧,用于通知附近的无线设备网络的存在和配置信息。通过调整beacon interval,可以控制信标帧的发送频率,从而影响无线网络的性能和功耗。较短的beacon interval可以提高网络的响应速度和实时性,但会增加信道占用和功耗;较长的beacon interval可以降低信道占用和功耗,但网络响应速度和实时性会受到影响。
