Antenna Positioning¶
For optimal reception of Bluetooth, Wi-Fi®, and cellular signals, ensure that radio waves are not obstructed by housing parts, labels, or surrounding objects and structures.
- Only mount the device in the installation position shown in Mount the Device.
- Choose a mounting location with minimal obstructions to ensure reliable communication.
- Do not apply additional labels to the device, as certain materials may significantly reduce signal quality.
- Do not modify the device or its surroundings in a way that affects antenna performance.
- The system integrator is responsible for ensuring adequate antenna performance and compliance with applicable regulations.
Antenna spacing¶
Maintain sufficient distance between antennas to avoid interference.
- The distance between antennas should be greater than 1/4 of the wavelength
- Avoid distances that are multiples of the wavelength
- When using multiple antennas, base the minimum distance on the lowest frequency
Example:
If using GNSS and Wi-Fi® antennas, maintain a minimum distance of 4.8 cm between antennas.
Internal Antennas¶
Internal antennas are located inside the upper part of the device housing.
The position of the internal antennas is fixed within the device. Signal performance therefore strongly depends on the device orientation and installation environment.
The positions of the internal antennas are shown in the following image.
