IoT Tags and Tracking Devices

We are living in a world where we have a large number of personal objects such as a mobile phone, car keys, laptop, headphones, etc. and more. This makes it increasingly difficult to keep tabs on all our valuables and possessions. This has brought about a new trend based on real-time tracking devices that let you know where these items are when you need them. Moreover, in day-to-day life, it's become important to also track the current location and health status of employees and visitors when they enter or leave an industrial environment and even beings that are very dear to us including children and pets.

在跟踪人员或特定设备时,除了获知其位置,全天候监测目标周边的温度、湿度和噪声等环境条件也很重要。加速度计的使用也有助于监测其运动,以检测其当前是否清醒、正在跑步或走路,特别是目标是否在一段时间内由于健康或安全问题而未发生移动。

为了确保与物联网跟踪器的不间断通信,连接是一个重要的考虑因素 - 无论是使用NFC、蓝牙低功耗(BLE)和Wi-Fi进行短距离通信,还是使用LPWAN、NB-IoT和LoRa等协议的远程通信。

然而,在无法使用GNSS的室内环境下,还是需要用到基于BLE技术(具有AoA,到达角)、超宽带(UWB)或Wi-Fi的基础设施。
