摘要
With the miniaturization of communication devices, the demand for hours is low power and low cost communications. Therefore, a communication system is designed which allows the device to exchange data using the environment RF as the only signal source. This design avoids the expensive process of generating radio waves. Environmental backscatter communication is more energy efficient than existing radio communication. This approach utilizes existing environmental Wi-Fi signals to eliminate the demand for wires and batteries, thereby contributing to ubiquitous communications. The device can even communicate previously where it cannot be accessed because it cannot provide a dedicated infrastructure. In this paper, a secure environment for backscatter communications, which enables intelligent vehicles to automatically enter a secure building, is proposed and simulated.
