FAQ

1. HoneyComm IoT 's Bluetooth AoA high-precision positioning and the traditional Bluetooth Beacon solution? The following is a comparative analysis from four dimensions:

——In terms of positioning accuracy , HoneyComm IoT Bluetooth AoA high-precision positioning system adopts the latest Bluetooth 5.1 technical specification and is based on the positioning principle of Angle of Arrival (AoA), which can improve positioning accuracy to sub-meter or even centimeter level. The traditional Beacon positioning solution is based on the three-point positioning principle of RSSI. Since the RSSI value is not a reliable judgment value, the positioning accuracy is relatively poor, generally within 3~5 meters.

——In terms of positioning methods , Bluetooth AoA positioning technology uses a passive positioning method, which only requires two positioning devices, the positioning base station and the positioning beacon. The positioning beacon transmits and the positioning base station scans and receives. Bluetooth Beacon positioning technology is an active positioning method, which requires three positioning devices, the positioning beacon, the positioning terminal and the Bluetooth gateway. The positioning beacon transmits the broadcast signal, and then the terminal scans, processes and forwards the broadcast signal, and transmits the positioning data to the server or background through communication with the Bluetooth gateway.

——From the perspective of power consumption , the base station of Bluetooth AoA uses PoE or DC power supply, and also uses BLE's low-power technology, so power consumption does not need to be considered too much. Beacons only need to send broadcast data, and with BLE's low-power technology, the power consumption of beacons is also very low. For example, beacons use CR2032 button batteries, which can be used for more than 6 months at a broadcast frequency of 1Hz (once per second). In the Bluetooth Beacon positioning solution, the positioning terminal needs to continuously scan the beacon's broadcast signal, and also needs to perform some data processing and solution forwarding. Therefore, the power consumption of the positioning terminal is often relatively high, so the frequency of positioning charging and maintenance costs are also relatively high.

——From the perspective of cost , the Bluetooth AoA positioning base station uses multiple antenna arrays to improve positioning accuracy, which requires some positioning data processing and solution. Through PoE power supply and data return, there is a certain wiring cost, and the deployment cost is relatively high; while the Bluetooth Beacon solution generally uses battery power supply, does not require wiring, so the deployment cost is relatively low, but the cost of replacing the battery of the positioning beacon in the later stage will be relatively high. At the same time, the positioning gateway also needs to be installed through wiring, which also has a certain deployment cost. In addition, the positioning terminal involves data processing and solution, so the cost of the positioning terminal is often relatively high .

       Therefore, it is necessary to comprehensively consider the cost of the solution based on project needs, positioning accuracy requirements, maintenance costs and project budget, and select a suitable solution. When appropriate, you can consider a fusion positioning solution.

2. What is the difference between Bluetooth AoA positioning and UWB positioning?

HoneyComm Team : High-precision Bluetooth AoA positioning technology has advantages over UWB in terms of accuracy, power consumption, cost, positioning method and compatibility :

High accuracy . The accuracy is equivalent to or higher at the same deployment density, with a typical accuracy of 30~50cm;

Low power consumption . The Bluetooth AoA positioning beacon can be used for more than 1 year (powered by a button battery), while the UWB beacon with the same battery capacity usually lasts between 1 week and 1 month;

Low cost . Bluetooth AoA positioning beacons generally cost between 10 and 20 yuan, while UWB beacons generally cost between 100 and 200 yuan.

A single base station can perform two-dimensional positioning . A single AoA base station can perform accurate two-dimensional positioning, and a single UWB base station can perform presence detection.

Good compatibility . Bluetooth AoA positioning is compatible with existing mobile phones and supports accurate positioning of mobile applets, while existing mobile phones basically do not support UWB.

Note: 1-2-4-5 is obvious advantage of bluetooth AOA. 3-6 is excellent advantage of Bluetooth Low Energy.

3. What is the positioning accuracy of HoneyComm IoT Bluetooth AoA positioning technology? What is the coverage range?

HoneyComm Team : Bluetooth AoA positioning belongs to the sub-meter level (0.1~1m) positioning technology, and the typical positioning accuracy is 30cm~50cm. The coverage range is related to the installation height of the base station. Generally, the coverage radius is 1.5~2 times the base station installation height difference (base station installation height-beacon height). For example, if the installation height is 5 meters, the coverage radius is approximately [1.5~2]x (5-1) = [6~8] meters, which can be used to estimate the location and number of positioning base stations.

4. HoneyComm IoT Bluetooth AoA positioning technology anti-interference? Can the positioning signal penetrate walls?

HoneyComm Team : Bluetooth AoA positioning also belongs to the 2.4GHz communication range and will also be interfered by the 2.4G signal of the same frequency . AoA positioning technology supports autonomous channel selection, and can select different communication channels according to the network environment of the project site to reduce the impact of co-channel interference. Since it belongs to the category of wireless communication, the positioning signal will inevitably be affected by the signal attenuation of the propagation medium. In actual projects, whether it is Bluetooth AoA, UWB, RFID, WIFi and other wireless positioning technologies, they are generally affected by walls, glass and other media. The usual practice is to perform some filtering processing on the algorithm, and generally consider filtering out the signal that penetrates the wall.

5. HoneyComm IoT Bluetooth AoA positioning support mobile phones as positioning beacons? How to implement it? What are the application scenarios?

HoneyComm Team : HoneyComm IoT Bluetooth AoA positioning supports mobile phones as positioning beacons, which can be realized through mobile phone APP or WeChat applet. Software system integrators integrate the APP SDK or applet SDK provided by HoneyComm IoT into their own APP or applet to realize AoA precise positioning. It is generally used for indoor navigation, finding people and objects in scenes such as shopping malls, hospitals, stations, airports, exhibition halls, etc., and does not need to be equipped with a positioning beacon separately. The user's mobile phone can be used as a beacon.

6. HoneyComm IoT Bluetooth AoA positioning base station support docking with customer or third-party beacons? How to dock? What are the requirements for positioning beacons?

HoneyComm Team : It supports docking with customers' own beacons or third-party beacons. HoneyComm IoT will provide docking SDK or docking data protocol, and customers or third parties can do secondary development docking with positioning beacons. HoneyComm IoT Bluetooth AoA positioning base station supports docking with Bluetooth positioning beacon terminals above BT4.0, and also supports docking with active 2.4G positioning beacon terminals.

7. Can HoneyComm IoT Bluetooth AoA positioning system provide API interfaces to support application system docking? What API interfaces can be provided?

HoneyComm Team : HoneyComm IoT Bluetooth AoA positioning system supports providing HTTP , UDP , MQTT and other API interfaces to connect with upper-level application systems.

8. What application scenarios is Bluetooth AoA positioning technology suitable for?

HoneyComm Team : No single positioning technology can meet the requirements of all scenarios. You can use the appropriate positioning technology solution based on project requirements. You can evaluate which positioning technology solution to use based on the positioning object, positioning accuracy requirements, project site environment, project budget, etc.

From the perspective of the positioning object, the scenarios for positioning people include personnel management needs in public security, procuratorial, judicial, factory manufacturing, medical and nursing institutions, supermarkets and exhibition halls, smart transportation, etc.; from the perspective of positioning objects, it includes asset positioning management application scenarios such as logistics warehousing, factory production equipment, medical equipment, supermarket products and shopping carts.

From the perspective of positioning accuracy, for those that require refined management requirements, such as electronic fences, high-risk operation warnings, etc., it is necessary to adopt positioning technology with higher positioning accuracy. Bluetooth AoA positioning can achieve sub-meter or even centimeter-level positioning accuracy, so it can meet the requirements of high-precision positioning.

From the perspective of the project site environment, HoneyComm IoT Bluetooth AoA provides positioning base stations suitable for installation heights from 2m to 30m to meet the requirements of different application scenarios.

From the perspective of project budget, HoneyComm IoT Bluetooth AoA can also integrate other positioning technologies to control project cost budget.
