During link planning, such factors as distance, obstacles, humidity, temperature, atmosphere pressure and the link margin should be taken into account. Radio waves in the 70.5-76 GHz frequency range encounter additional atmospheric attenuation beyond that which is expected in free space due to water absorption, including rain fade. The amount of additional atmospheric attenuation will vary, depending on your specific installation environment. So we strongly recommend to use the InfiPLANNER tool for link planning where the rain impact is taken into account.

• Keep 100% clear line of sight between devices. In case of installations over vegetation and forest, make sure the direct line of sight stays above the trees; in urban environments - above the tallest buildings along the radio path.
• Install wireless devices as far as possible from other radio devices (the recommended distance is at least 2 meters between the edges of the antennas).
• Install devices from power lines with a voltage higher than 35 kV at a distance at least 100-150 meters.
• Make sure the devices are located outside the area of water streams and splashes formation, which can affect the enclosure for a long time.
• 70 GHz antenna has a very narrow beam, keep devices directed strictly to each other.
