Prospects Bluetooth remote parking system with the rapid social and economic development in the 21st century, more accelerated rhythm of people's lives, the quality of life also demanding. Car has gradually become a vehicle for people to travel. The rapid development of the vehicle to the traditional manual card parking management system also brought enormous pressure. , The rush hour waiting in line card, uphill driveway parking card, credit card and other rain and snow to reach a lot of inconvenience. In recent years, with the rapid development of wireless mobile communications, new technologies are emerging. Based on the birth of Bluetooth communication technology in Bluetooth remote parking system to convenient, saving, saving time, fuel and other traditional products can not match advantage, will completely replace the traditional manual credit card parking system. In the near future, based on Bluetooth technology Bluetooth remote parking system will form a new wave of overwhelming swept the entire industry. Particularity parking system application, and not any one remote reader devices can serve their purposes, in the practical application of the signal can penetrate automotive window film, lane adjacent signal interference, signal with the car interference, microwave radiation hazards, signal attenuation, electromagnetic compatibility and other key technology to become an important factor in the stability of the product.
