 If there are other radios or transmitters located on the device (such as a Bluetooth radio), place the
devices as far apart from each other as possible. Also, make sure there are at least 25 dB isolation
between Bluetooth antenna and Wi-Fi antenna.
 Ensure that there is the maximum allowable spacing separating the antenna connectors on the Laird radio
from the antenna. In addition, do not place antennas directly above or directly below the radio.
 Laird recommends the use of a double shielded cable for the connection between the radio and the
antenna elements.
 Be sure to put the capacitor on the power pin as close as possible to reduce the radiation issue.
 Use proper electro-static-discharge (ESD) procedures when installing the Laird radio module.
 In order to get maximum throughput when operate at MIMO 2x2, two antennas with at least 25 dB
isolation is recommended.
 To avoid negatively impacting TX power and receiver sensitivity, do no cover the antennas with metallic
objects or components.
