GPRS1420D is a multi-channel pulse emission tag, which is at the heart of various applications such as distance and positioning, personnel and asset management, supply chain automation and so on. It is widely used in areas of public systems, asset and personnel management, anti-theft control, access control and so on. GPRS1420D has many advantages, such as accurate positioning, anti-interference, and small size. It is also a low-cost solution, compared with other technologies.

Generally speaking, the application of GPRS1420D can be divided into two categories, indoor and outdoor application. For indoor applications, it is mainly used for asset and personnel management inside the building, such as identifying staff in the building, checking visitor information, monitoring employee attendance, and managing inventory and assets. The principle behind is based on the distance and position of the tag and the reader. With the RFID reader, GPRS1420D can communicate with the reader, and send data back and forth to the reader, so that the application can achieve its designated work. For outdoor applications, GPRS1420D is mainly used for asset tracking and location, such as inventory tracking in outdoor environment, emergency rescue alert, and vehicle tracking. The working principle behind is based on the signal emitted from the tag to the receiving device, such as the reader. GPRS1420D is an active tag, and the data transmission is based on the signal emitted from the tag. By collecting and analyzing the signal emitted by the tag, the range and position of the tag can be accurately determined.

Designing indoor and outdoor applications based on GPRS1420D is relatively simple and cost effective. There are a few tips that need to be aware when applying GPRS1420D, firstly is the distance of signal emission, the more energy emitted from the tag, the further distance the tag can transmit the signal, however, too much energy will result in the tag’s quick battery drain. Secondly, the interference of different environment, different environment will have different interference towards the signal emission of GPRS1420D. Lastly, due to the interference caused by different environment, it is recommended to use a mesh network technology. Mesh network technology can provide multiple paths for reader to identify the tag, which can improve the accuracy of positioning.

In conclusion, GPRS1420D is a popular multi-channel pulse emission tag used for various applications. It has many advantages, such as accurate positioning, anti-interference, and small size. Designing applications based on GPRS1420D is relatively easy, but one needs to aware of its signal transmission distance, and interference caused by various environment. Lastly, it is suggested to use a mesh network technology to improve the accuracy of positioning.
