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.

Technical challenges

When tracking personnel or certain equipment, in addition to know their position, but it’s also important to monitor the environmental conditions as temperature, humidity and noise around these assets throughout the day. The use of an accelerometer is also useful to monitor their movements to detect if they are awake, running or walking and especially if they haven't moved in a certain time as a result of a health or safety issue.

To ensure constant communication with an IoT tracker, connectivity is an important consideration, whether it is short-range communication using NFC, Bluetooth Low Energy (BLE) and Wi-Fi or long-range systems such as LPWAN, NB-IoT, and LoRa.

However, in indoor situations where GNSS cannot be used, an infrastructure based on BLE technology with AoA (angle of arrival), ultrawide band (UWB) or Wi-Fi can be really useful.
