Pre-Installation Preparation > What to prepare before on-site installation: checking supplies, preparing the floor plan, measuring the site, and planning locator positions. ## 1) Installation Supplies The items below are not included in the standard package and must be purchased separately. | Item | Quantity | Notes | | - | - | - | | Power adapter | Same as locators | ·5V / 2A or higher (10W) | | Cable | Same as locators | ·USB Type-C power cable (USB-A to C or C to C)·**2 – 3 m length recommended** considering the mounting height (2 – 3 m) (extend with a power strip if the outlet is far away) | | Power strip | As needed | ·For extending power when outlets are far away or cable length is insufficient | | Tape measure or laser rangefinder | 1 | ·For measuring actual distances and coordinates | | Masking tape · pen | 1 | ·For writing the last 4 digits of each locator's UWB 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 | | Power bank (optional) | As needed | ·Can be used where no outlet is available (10,000 mAh or more recommended) | | Line tape (optional) | 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 (optional) | 1 | ·For securing cables that run across the floor | Depending on the installation method, you may also need the following. | Method | Additional supplies | Notes | | - | - | - | | Wall mounting | Double-sided tape, ladder | ·Prepare a ladder for working at the recommended height (3 m, minimum 2 m)·Wipe dust and debris off the mounting surface and fix firmly so it does not fall (for rented spaces, confirm in advance whether walls may be marked) | | Tripod mounting | 4 tripods | ·Prepare tripods adjustable to **at least 2 m** in height·Suitable when wall mounting is difficult or walls must not be damaged (fix level and stable so they do not wobble) | ## 2) Preparing the Floor Plan Prepare the floor plan file to upload to GeoSpace. 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. * A DXF fills 'Actual plan size' automatically from the drawing, which suits large spaces where measuring the full width and depth is impractical. Check the following two points when preparing one. * A DXF that references other drawing files is displayed without the referenced content (walls, grid lines, and so on). Ask whoever provides the drawing to export it as a single DXF that includes all referenced files. * Objects left far outside the building make the drawing extent larger than the real space. Ask for a file with unnecessary objects outside the building removed. ![Two-step diagram: choose a reference direction, then take the bottom-left corner from that direction as the reference point (0, 0)](https://mintcdn.com/onecheck/E2whs2uAjcPfu5dJ/images/geospace/1.site-survey-coord-north-origin-en.svg?fit=max\&auto=format\&n=E2whs2uAjcPfu5dJ\&q=85\&s=e3cc40d233cf5fd0daaa4b994fcec727) Set a reference direction whether or not you have a floor plan. Once set at this stage, the same reference direction must be kept throughout plan upload, position measurement, and verification. * Choose the top edge of the space. Any direction works as the reference, but placing the entrance on the "bottom edge" of the plan is usually the most convenient. * Based on the reference direction, take the bottom-left corner as the reference point. We recommend marking the reference point on the floor with line tape; you can then use the same spot as the reference for later coordinate checks and verification. > [!NOTE] > > You can set up a positioning environment without a floor plan, but when possible we recommend > registering a plan image and placing the locators based on it. If you skip plan registration, > omit it in [3. Space Registration](/en/locator/spaces#3-registering-and-setting-up-the-floor-plan-optional) > and enter coordinates directly, based on the relative positions between locators, in > [6. Activating Positioning](/en/locator/placement). > Either way, always measure the actual space regardless of whether you use a plan. ## 3) 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·The width and depth values are entered as the actual plan size in [3. Space Registration](/en/locator/spaces) | | Height of the target space | ·Used to decide the locator installation height·Recommended installation height: 3 m (if height is limited by site conditions, minimum 2 m) | ## 4) Planning Locator Positions ![Diagram of 4 locators placed at the corners of a space, showing installation height, width, and depth](https://mintcdn.com/onecheck/E2whs2uAjcPfu5dJ/images/geospace/1.site-survey-measure-height-width-en.svg?fit=max\&auto=format\&n=E2whs2uAjcPfu5dJ\&q=85\&s=e8b8e5e4e05182b146fd712ad597620f) ![Diagram of 4 locators placed at the corners of a space, showing installation height, width, and depth (mobile)](https://mintcdn.com/onecheck/E2whs2uAjcPfu5dJ/images/geospace/1.site-survey-measure-height-width-mobile-en.svg?fit=max\&auto=format\&n=E2whs2uAjcPfu5dJ\&q=85\&s=bde263b3d60e9e2be6b34a44cbe305af) Positioning requires at least 4 locators, and we recommend arranging them in a **rectangle (rectangular layout)** so they cover the entire target space. Mark the approximate installation position of each locator and the nearest power outlet on the plan or on paper. * 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 **3 m from the floor** (if height is limited by site conditions, **minimum 2 m**). > [!NOTE] > > **Installation height** \\ > > So that signals sent from the locators to phones below are not blocked by people or fixtures, we **recommend an installation height of 3 m** (if height is limited by site conditions, **minimum 2 m**), and align all 4 locators at the same height. * If you bunch all four against one wall or line them up in a row, the position shown in the app drifts away from where you actually are or jitters in place, so spread the four out to surround the space. (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 (if outlet connection is difficult, a power bank can be used instead). > [!CAUTION] > > 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. > [!NOTE] > > 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) to the other locators. > (See [0. Overview](/en/locator/overview#3-terminology) for master locator and line of sight.) ## Checklist > [!NOTE] > > Once all items below are confirmed, you can move on to the next step. > > | # | Item | Check | > | - | - | :-: | > | 1 | Installation supplies are ready. | ☐ | > | 2 | The floor plan image to upload to GeoSpace is ready.
