16. RF L AYOUT D ESIGN G UIDELINES / P RECAUTIONS
The following is a list of RF layout design guidelines and recommendation when installing a Laird radio into your
device.
 Do not run antenna cables directly above or directly below the radio.
 Do not place any parts or run any high speed digital lines below the radio.
 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 is at least 25 dB isolation between
the Bluetooth antenna and the 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.
 To get maximum throughput when operate at MIMO 2x2, two antennas with at least 25 dB isolation are
recommended.
 To avoid negatively impacting Tx power and receiver sensitivity, do not cover the antennas with metallic
objects or components.
 Opening/handing/removing must be done on an anti-ESD treated workbench. All workers must be also
have undergone anti-ESD treatment.
 The devices should be mounted within one year of the date of delivery.
