Access Point Placement for Location Services

To ensure the best possible accuracy and stability, follow these guidelines:

  • Mount the access points (APs) on the ceiling, with the LED facing the floor.

    Example

    • Ceiling mounting results in the best directionality for the Bluetooth Low Energy (BLE) beams.

    • If ceiling mounting isn’t possible and you must mount the AP on a wall, pole, column, or similar structure, use brackets to position the AP with the LED facing the floor.

  • Ensure that the AP is 9 to 15 feet (2.7 to 4.5 meters) above the floor.

    • The height requirement ensures that BLE clients receive a strong received signal strength indicator (RSSI) and the best possible directionality for the BLE beams.

    • If you need to install APs in an area with ceilings higher than 15 feet, consult with a sales engineer.

    • We do not recommend above-ceiling mounting. Again, consult with a sales engineer.

  • Each AP should have an unobstructed line of sight to at least two other APs.

    • Optimal BLE range is a radius of approximately 15 meters (49 feet) from the AP.

      AP Placement for Optimal BLE Coverage

    • Install APs within 10 to 15 meters (32 to 49 feet ) of one another.

    • For wayfinding, be sure to provide coverage at junction points and corners.

  • Don't place APs any closer than 8 meters (26 feet) in the same room or space. Closer placement offers no benefit in terms of coverage and could cause interference.

    Note:

    If APs are in different rooms, separated by a wall, close placement doesn't pose an issue.

  • For corners, hallways, and areas where you need only BLE and not Wi-Fi services, consider using Juniper BT11 access points.

  • Don't install an AP:

    • Behind, inside, or on top of other objects.

    • On the floor.

    • Next to metal, glass, or concrete.
