Resolve direction to reveal a more precise location. For medical equipment, production tools and personnel tracks that need finer location detail. Array gateways receive compatible tag signals and calculate position from angle observations and installation geometry. [Discuss your solution](https://www.rpilink.com/contact/) SOLUTION PROFILE Positioning objective Sub-meter target; verify the model and site System components AoA array gateways + compatible tags + positioning engine Medical equipment Tools and fixtures Personnel tracks HOW IT WORKS ## From radio signals to usable location. Compatible tags transmit direction-finding signals. A receiving antenna array collects phase information to estimate the angle of arrival. The engine combines gateway coordinates, orientation and target height or multiple observations to calculate position. SYSTEM ARCHITECTURE CONCEPT · NOT LIVE DATA 01 ### Transmit Compatible tags send configured direction-finding signals. 02 ### Measure angles Array samples estimate azimuth and elevation. 03 ### Calculate position Combine station coordinates, orientation and height. 04 ### Integrate ACServer pushes results to the business system. ### Finer location detail Direction information supports a transition from zones to coordinates. ### PoE installation Ceiling mounting allows centralized network and power planning. ### Application interfaces Connect through ACServer MQTT, HTTP or WebSocket interfaces. DEPLOYMENT ESSENTIALS ## Check the deployment requirements. 01 Indoor JJ-IS40BXPA accuracy is specified as <0.5m unobstructed; the outdoor version specifies within 1m. Do not interchange these figures. 02 A coverage radius of about 1.5 times mounting height is nominal. Account for blind spots, target height and edge accuracy. 03 Standard iBeacon devices or a Bluetooth 5.x label alone do not establish AoA support. Verify direction-finding packets and firmware.

Product capabilities remain subject to their specifications and selection validation. SELECTION QUESTIONS ## BLE AoA positioning for equipment and personnel ### How does Bluetooth direction finding support BLE AoA asset tracking? A compatible tag sends signals to an antenna-array gateway, which estimates their arrival angle. The location engine uses station coordinates and installation geometry to calculate position. Gateway orientation, mounting height and obstructions need to be included in calibration. [View the indoor BLE AoA gateway](https://www.rpilink.com/products/product-12/) ### What should a hospital asset tracking trial measure? For medical equipment, test room transitions, detection around beds and metal carts, tag attachment and battery policy. Agree whether the goal is room identification or coordinates, then validate the chosen gateway and tag combination in representative occupied spaces.
