The antenna system used affects the performance of a wireless system considerably. The use of appropriate antennas can significantly increase the performance of your wireless network, which means that this part of the installation deserves close attention.

Omnidirectional antennas

Directivity of omnidirectional antennas

Omnidirectional antennas are used when the wireless modules are facing different directions or are mobile. As a result of their low gain, they are more suitable for short to medium distances. In reflective indoor environments where there is no line of sight, the signal may be reflected from the sender to the receiver. In such cases it is important to ensure that the omnidirectional antenna is not mounted immediately in front of reflective (metallic) surfaces.

The ideal installation location is the top of a mast or on a control cabinet so that the antenna has the largest possible amount of free space in all directions. In the case of multiple omnidirectional antennas, these should be installed with sufficient spacing.

Typical fields of application:

  • Bridging short to medium distances
  • Networks with several devices pointing in various directions
  • Versatile applications

Panel antennas

Directivity of panel antennas

The use of panel antennas is recommended in permanently installed, remote stations when large distances need to be covered with a line of sight. Panel antennas emit the transmission power in a preferred direction. This increases the range and reduces the chances of interference from other users outside the pattern.

The higher the gain of a directional antenna, the smaller its pattern (opening angle). This means that the antennas need to be precisely aligned with one another.

Typical fields of application:

  • Bridging large distances
  • Point-to-point connections
  • Stationary or linear applications
