Choose a warehouse positioning architecture around the decisions your operation needs to make, then compare complete systems under the same site conditions. By Jinju Intelligence 21 September 2026 2 original diagrams · Practical engineering guide THE PRACTICAL ANSWER ## What to decide first Shortlist BLE AoA when compatible direction-finding tags and array locators fit the workflow. Shortlist UWB when time-based ranging or a suitable UWB angle system fits the required observations. Neither technology name settles accuracy, battery life or project cost; the rack layout and a matched site trial should decide. 01 / PRACTICAL GUIDE ## Start with the warehouse decision, not the radio label Finding a pallet in the correct storage zone is different from distinguishing adjacent bays or following a forklift through a crossing. Write down the action triggered by location, the acceptable error and how old the information may be. Specify whether the target is a person, a tool, a pallet or a vehicle, because mounting and movement differ. Build a short requirements sheet containing the floor plan, rack heights, occupied aisles, tag count, moving-tag count and charging workflow. Mark areas that require coordinates and areas where a zone event is sufficient. This avoids paying for uniform precision across spaces that do not need it. 02 / PRACTICAL GUIDE ## Compare the measurement chain end to end Bluetooth Angle of Arrival uses a receiving antenna array to estimate the direction of a compatible tag signal. A location engine combines the observations with locator position, orientation and other constraints. An ordinary BLE advertising tag does not automatically provide the direction-finding signal required by a particular AoA system. UWB offers several architectures. TWR exchanges messages to estimate range; uplink TDoA uses a synchronized receiver network; a UWB angle system adds direction measurements. Ask the supplier which method is implemented rather than comparing “BLE AoA” with an unspecified “UWB” product. Include the tag, receiver, firmware and engine in that answer. ![BLE AoA tags feed array locators and a geometry engine, while UWB tags feed a selected ranging or angle architecture before warehouse applications.](https://www.rpilink.com/knowledge/warehouse-choice.svg) Compare complete observation chains. The UWB branch represents alternative architectures, not features every UWB device includes. ORIGINAL CONCEPT DIAGRAM · NOT TO SCALE · SWIPE TO EXPLORE 03 / PRACTICAL GUIDE ## Use the same loaded-warehouse pilot for both systems Metal shelving, stock and vehicles can change which paths reach a receiver. An unobstructed coverage radius is a starting point for planning, not proof that every rack aisle is covered. Test corners, the ends of aisles, rack intersections and areas where workers turn their bodies between the badge and receiver. Agree on surveyed checkpoints and a repeatable moving route. For each candidate, record horizontal error at checkpoints, valid-fix availability, update age and missed or duplicate zone events. Keep static accuracy separate from tracking delay: a smooth line on a dashboard can hide stale measurements. Use the same mounting position, tag population and traffic conditions when comparing results. ![A warehouse acceptance route crosses aisles, a rack corner and a zone boundary, with checkpoints for error, fix availability and data freshness.](https://www.rpilink.com/knowledge/warehouse-pilot.svg) Suggested acceptance-test structure. Checkpoint positions and thresholds should come from the actual warehouse process.

Include time spent assigning tags, checking battery status and replacing lost units in the evaluation. For vehicle tracking, test the final mounting location with the vehicle loaded. Request two comparable bills of materials covering installation, network equipment, software and support. Where different zones need different outputs, evaluate a mixed deployment with a common asset identity and explicit position-source labels. Keep the integration cost visible instead of assuming that two radio systems merge automatically. DECISION WORKSHEET ## Questions to compare BLE AoA and UWB warehouse proposals | Decision | BLE AoA proposal | UWB proposal | | --- | --- | --- | | Measurement | Which tag signal and array estimator? | TWR, TDoA, angle measurement or a combination? | | Infrastructure | Locator pose, height and overlapping view | Anchor geometry and synchronization if required | | Capacity | Tags, reporting policy and receiver processing | Packet schedule, exchanges and observation capacity | | Acceptance | Error, availability and age on the agreed route | The same criteria and the same operating conditions | NEXT STEPS ## Your project checklist - Identify the smallest business zone that must be distinguished. - Trial the final tag mounting on actual people, pallets or vehicles. - Ask for raw timestamps and quality flags in addition to a dashboard. - Compare installation and operating costs over the same period. COMMON QUESTIONS ## Frequently asked questions ### Is UWB always more accurate than BLE AoA? There is no useful universal ranking without specifying the hardware, deployment and test statistic. Compare measured results for the intended task instead of combining best-case numbers from different datasheets. ### Can I reuse existing Bluetooth beacons? Only if the tag signal and firmware are compatible with the selected receiver and measurement method. Existing RSSI beacons should not be assumed to support AoA. ### Which system is cheaper for a large warehouse? Obtain a site-specific design for each candidate. Hardware price alone excludes mounting access, network runs, commissioning, software and tag maintenance. ## References and further reading Technical background is linked below.
