What is the difference between the Bluetooth AoA high-precision positioning of the core Internet of Things and the traditional Bluetooth Beacon solution? The following is a comparative analysis from four dimensions:

--from the positioning accuracy, the nuclear-core IOT Bluetooth AoA high-precision positioning system adopts the latest Bluetooth 5.1 technical specification. Based on the positioning principle of angle of arrival AoA(Angle of Arrival), the positioning accuracy can be improved to sub-meter level or even centimeter level. The traditional Beacon positioning scheme is based on the three-point positioning principle of RSSI, because the RSSI value is not a reliable judgment value, so the positioning accuracy will be relatively poor, generally in 3~5 meters positioning accuracy;

--in terms of positioning, the Bluetooth AoA positioning technology adopts a passive positioning method, and only two positioning devices, a positioning base station and a positioning beacon, transmit the positioning beacon, and scan and receive the positioning base station. The Bluetooth Beacon positioning technology is an active positioning method, which requires positioning devices of three parts: a positioning beacon, a positioning terminal and a Bluetooth gateway. The positioning beacon transmits a broadcast signal, then scans, processes and forwards the broadcast signal through the terminal, and transmits the positioning data to the server or the background through communication with the Bluetooth gateway.

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

--from a cost perspective, Bluetooth AoA positioning base station uses multiple antenna arrays to improve positioning accuracy, requires partial positioning data processing and calculation, and uses PoE power supply and data return, so there is a certain wiring cost, and the deployment cost will be relatively high. However, Bluetooth Beacon scheme generally uses battery-powered beacons and does not need to pull wires, so the deployment cost is relatively low, however, the cost of replacing the battery maintenance of the later positioning beacon will be relatively high. At the same time, the positioning gateway also needs to be installed through wiring, and there is also a certain deployment cost. Moreover, because the positioning terminal involves data processing and calculation, the cost of the positioning terminal is often relatively high.

Therefore, it is necessary to comprehensively consider the cost of the solution according to the project requirements, positioning accuracy requirements, maintenance costs and project budget, select the appropriate solution, and consider the fusion positioning solution when appropriate.
Bluetooth AoA positioning and UWB positioning?

answer.:high precision Bluetooth AoA positioning technology fromaccuracy, power consumption, cost, positioning method and compatibilityand other aspects have advantages over UWB:

precision. comparable or higher accuracy at the same deployment density,Typical accuracy 30~50cm;
power consumption. The use time of Bluetooth AoA positioning beacon can reach more than 1 year (button battery power supply), and the use time of UWB beacon is usually between 1 week and 1 month under the same battery capacity;
cost. Bluetooth AoA location beacons generally cost more than ten to tens of dollars, while UWB beacons generally cost about one hundred to 200 or 300 dollars;
single base station for two-dimensional positioning. AoA single base station can be accurate two-dimensional positioning, single UWB base station to do presence detection.
compatibility. Bluetooth AoA positioning is compatible with existing mobile phones and supports accurate positioning of mobile phone applets, while existing mobile phones basically do not support UWB.

5. What is the positioning accuracy of the core Internet of Things Bluetooth AoA positioning technology? What is the coverage?

answer.:Bluetooth AoA positioning is a sub-meter (0.1~1m) positioning technology, with a typical positioning accuracy of 30cm ~ 50cm. The coverage is related to the installation height of the base station. Generally, the coverage radius is 1.5~2 times of the installation height difference of the base station (installation height of the base station-beacon height). For example, if the installation height is 5 meters, the coverage radius is about [1.5~2]x(5-1)=[6~8] meters, so as to estimate the location and quantity of the positioning base station.

6. What is the anti-interference performance of the core IoT Bluetooth AoA positioning technology? Can the positioning signal go through the wall?

answer.:Bluetooth AoA positioning also belongs to the communication category of 2.4GHz, and will also receive signal interference of 2.4G with the same frequency. The core AoA positioning technology supports independent channel selection, and can select different communication channels according to the network environment of the project site to reduce the influence of same frequency interference. Because it belongs to the category of wireless communication, the positioning signal will inevitably receive the problem of signal attenuation of the communication medium. In actual projects, whether it is Bluetooth AoA, UWB, RFID, WIFi and other wireless positioning technologies, they will generally receive the influence of media such as walls and glass. The usual practice is to do some filtering processing on the algorithm, and generally consider filtering out the signals passing through the wall.

7. Does the core IoT Bluetooth AoA positioning support mobile phones as positioning beacons? How? What are the application scenarios?

answer.:Core IOU Bluetooth AoA positioning supports mobile phones as positioning beacons, which are realized by means of mobile phone APP or WeChat applets. Software system integrators integrate APP SDK or applet SDK provided by Core IOU in their own APP or applets to realize AoA precise positioning. Generally used in shopping malls, hospitals, stations, airports, exhibition halls and other scenes of indoor navigation, looking for people to find things, etc., do not need to be equipped with a separate positioning beacon, the user's mobile phone can be used as a beacon.

8. Does the core IoT Bluetooth AoA positioning base station support the docking of customer or third-party beacons? How to dock? What are the requirements for positioning beacons?
