[WLAN From Beginner to Expert — Common WLAN Delivery Cases] Uninstallation of an RF Load on a Radio Port

For a radio port that is not connected to an antenna, it is recommended that a 50-ohm RF load be connected to the radio port to improve device reliability.

Let's take a look at a case.

Symptom

At a site, no RF load is installed on the idle radio port of an outdoor AP with external antennas, affecting device reliability.

Fault Location

If an outdoor AP with external antennas has an idle radio port unconnected, signals from the radio port will be reflected back to the AP, affecting signal and device reliability.

Solution

Install a 50-ohm RF load on the idle radio port. For details, see Cable Connection.

Summary

Outdoor APs often have high transmit power. Unused radio ports must be connected to 50-ohm RF loads to prevent radio interference, and the joint between the radio port and RF load must be sealed with waterproof insulation tape. Huawei offers 50-ohm RF loads with the part number 27110001 for you to purchase.
