Test Environment
Radio interference in the test environment should be as low as possible, so a shield room is recommended.
If there is no shielded room, it is recommended that a radio scanning tool be used to select a channel with little interference for the test. If interference of common channels is high, select radar channels for the test.
Keep the test terminal (for example, a laptop) close to the AP. Place the AP vertically, facing the top cover of the laptop. The distance between the AP and laptop ranges from 20 cm to 1 m, ensuring an RSSI of about –35 dBm for the laptop.
