We will guide you through an alternative. ## 2) Preparing the Verification iPhone and App These are the device and app used to confirm positioning after installation. Preparing them in advance lets you start verification right away on the day. | Item | Details | | - | - | | iPhone | ·iPhone 12 or later, iOS 27.0 or later (UWB support)·iPhone 11 and earlier have no UWB chip, so positioning will not work | | OneS1ght app | ·Install 'OneS1ght' (Onecheck Inc) from the App Store·Allow both the Location and Bluetooth permissions on first launch | | OneS1ght account | ·The email and password used to log in to the app·If you have no registered account, ask an organization administrator to invite you | ## 3) Installation Supplies | Item | Quantity | Notes | | - | - | - | | AN-500 locator | 4 | ·Minimum quantity to set up a detection area | | Power adapter · cable | Same as locators | ·USB-C · 5V/3A·Cables of 3 m or longer recommended | | Power strip | As needed | ·Consider outlet locations and the distance to each locator | | Tape measure or laser rangefinder | 1 | ·For measuring actual distances and coordinates | | Line tape | 1 | ·For marking the reference point (0, 0), zones, and other spots on the floor·Pick a color that stands out against the floor | | Paper tape | 1 | ·For securing cables that run across the floor | | Masking tape · pen | 1 | ·For writing the last 4 digits of each locator's MAC address on its front | | On-site Wi-Fi (2.4 GHz) | — | ·Used for locator registration and server connection·2.4 GHz only (5 GHz not supported)·Confirm the SSID and password in advance | Depending on the installation method, you may also need the following. | Method | Additional supplies | Notes | | - | - | - | | Wall mounting (permanent) | Double-sided tape, ladder | ·For rented spaces, confirm in advance whether the walls may be marked | | Tripod mounting (temporary · demo) | 4 tripods | ·Installs without damaging walls | ## 4) Preparing the Floor Plan Prepare the floor plan file to send to OneS1ght Support. You can use an image (PNG or JPG) or CAD (DXF) format. * The plan must accurately reflect the proportions and layout of the actual space. * Convert non-image formats such as PDF to PNG or JPG. * You can proceed without a plan. In that case, choose one corner of the space (the bottom-left corner when facing the entrance is recommended) as the reference point, mark it on the floor with line tape, and send the width and depth distance from the reference point to each locator together with the installation height. ## 5) On-Site Measurement Using a tape measure or laser rangefinder, measure and record the following. * Record measurements in meters (m) to two decimal places. | Measurement | Notes | | - | - | | Width and depth of the target space | ·Used as the baseline for plan scaling and locator coordinate entry·Used by OneS1ght Support for plan scaling and locator coordinate entry | | Height of the target space | ·Used to decide the locator installation height·Recommended installation height: 2.4 to 3 m (minimum 2 m) | ## 6) Planning Locator Positions Diagram of 4 locators placed at the corners of a space, showing installation height, width, and depth On the plan (image or printout), mark the approximate installation position of each locator and the power route to each spot. Positioning requires at least 4 locators, and we recommend placing them at the corners so they cover the entire target space. * When planning locator positions, consider the width and depth at each spot together with the installation height. Width and depth are measured wall to opposite wall; installation height is measured from the floor to the locator. We recommend mounting locators at 2.4 to 3 m on the wall. * Concentrating locators on one side or placing them in a near-straight line greatly increases positioning error, so place them to cover the detection area evenly.
(Keep at least 3 m between locators) * Locators need constant power, so check the nearest outlet before installing. Each locator must be installed where a power cable can reach it; installation may be limited where power is unavailable. Metal objects can interfere with positioning signals. Do not install locators close to metal objects (e.g., shelves, pillars, refrigeration units). Keep at least 0.5 m between each locator and any metal object. One of the locators acts as the **master locator**, the transmission anchor of the cluster. Which device is the master locator is communicated when the service is delivered. Place the master locator where it has the best possible line of sight (LOS, a clear view with no obstacles in between) to the other locators. ## Checklist Once all items below are confirmed, you can move on to the next step. | # | Item | Check | | - | - | :-: | | 1 | The on-site Wi-Fi (2.4 GHz) SSID and password are sent to OneS1ght Support. | ☐ | | 2 | The OneS1ght app is installed on the verification iPhone (12 or later) and the login account is confirmed. | ☐ | | 3 | Installation supplies are ready. | ☐ | | 4 | The floor plan file to send to OneS1ght Support is ready.
