Bluetooth AOA-Based Indoor Positioning Navigation Solution for Parking Space Guidance and Reverse Vehicle Finding

Overview of Bluetooth Positioning

With the increasing number of private vehicles, parking difficulty has become a significant social challenge. Neither GPS nor the BeiDou Navigation System can provide indoor navigation; they are limited to outdoor use. In recent years, the proliferation of large shopping malls and parking lots has compounded this issue. Within large parking facilities, multiple zones are often designated for easier management, resulting in complex traffic routes. When parking spaces are scarce, users waste considerable time searching for available spots, sometimes leading to congestion within the lot. Guiding vehicles to parking spaces and facilitating reverse vehicle finding are fundamental requirements for building smart parking systems.

Currently, there is a need to locate and navigate vehicles and individuals within parking facilities. Bluetooth technology offers the simplest and most convenient solution for this purpose. Bluetooth positioning is primarily divided into AOA (Angle of Arrival) Bluetooth positioning and beacon-based positioning.

1. Beacon-based positioning technology offers an accuracy of 3-5 meters. It requires at least three beacons for positioning, deployed uniformly at intervals of approximately 5 meters. A single beacon has a lifespan of around 3 years. Installation is simple with no on-site wiring needed, and the cost is low, enabling positioning and navigation for terminal devices.

2. Compared to beacon-based positioning, AOA Bluetooth positioning offers higher precision, achieving accuracy up to 30 centimeters. In terms of device management, AOA allows for centralized management of all positioning base stations. Deployment requires only one positioning base station to achieve 2D positioning, with coverage extending 1.5 to 2 times the installation height of the base station, resulting in a larger individual coverage radius. Overall, for the future trend of indoor positioning, West-HN Technology's Bluetooth indoor positioning aligns with current developments. With wearable devices now widespread across various sectors, the Bluetooth ecosystem is poised to leverage its inherent potential. The combination of 5G and Bluetooth for indoor positioning is expected to bring significant market benefits. West-HN Technology addresses current parking lot challenges—such as low entry/exit efficiency, difficulty finding parking spaces and vehicles, management complexities, and high management costs—through its AOA Bluetooth indoor parking navigation solution.

Hainan West-HN Technology Co., Ltd. introduces a smart parking solution, creating a high-cost-performance electronic map application system for smart parking lots. This system enables intelligent video-based parking space guidance, reverse vehicle finding, and visual intelligent operation management. It aims to provide a pleasant parking experience for vehicle owners while simplifying management for operators, thereby enhancing user satisfaction and reducing maintenance and management costs. The solution is compatible with various IoT Bluetooth devices and all Bluetooth 4.2-enabled mobile phones, serving the annual influx of 4 billion new Bluetooth devices. It may well establish another robust application scenario for Bluetooth, a wireless protocol already achieving great commercial success.
