Design and Implementation of Wireless Transceiver Module for Parking Control System

In this paper, we show the implementation of the low-cost RF transceiver module for parking control system. Super regenerative receiver scheme was adopted for this module due to its simplicity, low-cost, low power consumption and small number of components to improve reliability of the systems. For improving communication error rate by collision and in-band noise, dual-channel hopping scheme was adopted. Testing prototypes under the environment of simultaneous transmissions, we verified that the designed scheme is able to improve the success rate of data transmission of wireless parking control system cost effectively.
