In the last two decades, Bluetooth technology has seen rapid development, ushering in a new era of wireless connectivity. With its range and versatility, Bluetooth lets users connect devices and quickly and easily transfer data over short distances.
There are two main types of Bluetooth technologies: Bluetooth AoA (Angle of Arrival) and Bluetooth RSSI (Received Signal Strength Indication). Both technologies have their advantages and can be used in different scenarios.
Bluetooth AoA Technology
Bluetooth AoA and Bluetooth RSSI: What They Are, And Their Working Principle
Taking Blueiot’s complete set of solutions as an example, the RTLS smart logistics tracking system consists of four main components:
This cloud-based platform stores, processes, and displays tracking data. It allows users to track the location of items and staff in real-time and access analytics tools to gain insight into production processes.
Bluetooth RSSI is used to measure the strength of a Bluetooth signal at any given moment. The technology can be deployed in various scenarios, including indoor navigation, asset tracking, and proximity detection. The higher the signal strength, the easier it is for devices to communicate with each other over short distances. Furthermore, Bluetooth RSSI can identify which device is closest to a specific location, making it ideal for asset tracking and indoor navigation applications.
Differences between Bluetooth AoA and Bluetooth RSSI
The key differences between Bluetooth AoA and Bluetooth RSSI include the following:
Protocol: Bluetooth AoA uses the latest Bluetooth 5.1 protocol, while Bluetooth RSSI requires a minimum of Bluetooth 4.0+.
Typical accuracy: The typical accuracy of Bluetooth AoA ranges from 0.1 to 0.5 m, whereas that of Bluetooth RSSI is between 5 and 10 m.
Refresh rate: The refresh rate of Bluetooth AoA is higher than that of Bluetooth RSSI.
Tag power consumption: The tag power consumption of Bluetooth AoA is lower than that of Bluetooth RSSI.
Anchor cost: The anchor cost of Bluetooth AoA is generally higher than that of Bluetooth RSSI.
Tag cost: The tag cost for Bluetooth AoA is usually lower than that for Bluetooth RSSI.
loT anchor capabilities: The AoA locating anchor not only provides high-precision indoor positioning services, but also serves as a Bluetooth gateway to access all kinds of Bluetooth IoT sensor data, while RSSI devices don't.
