Backscatter

Backscatter technology, also known as backscattering, is an effective method for wireless data transmission between readers and passive transponders. In particular, this method is often used in long-range systems to transmit data over long distances.

The basic principle of backscatter technology is that the reader emits electromagnetic waves that hit the passive transponder. The transponder then modulates the reflected waves with the stored data and sends them back to the reader. This process allows information to be transmitted without the transponder needing its own power source.

Backscatter technology offers several advantages, including ease of implementation, low cost and high energy efficiency for passive transponders. It also enables efficient communication over long distances, making it ideal for applications such as asset tracking, logistics, access control and IoT applications.

In practice, backscatter technology is used in various areas. In the field of asset tracking, for example, companies can monitor and track stock levels by using passive transponders with backscatter functionality. In retail, these transponders can also be used for inventory management and theft protection.

Another area of application is access control, where backscatter tags can be used as a means of identification to control access to buildings or specific areas. In addition, the technology is increasingly being integrated into IoT applications to enable wireless communication and data transmission in networked environments.

Overall, backscatter technology is a powerful method of wireless data transmission that is used in a wide range of applications and has the potential to improve efficiency and productivity in various industries.
