RF LAYOUT DESIGN GUIDELINES/PRECAUTIONS
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 are at least 25dB isolation between
Bluetooth antenna and Wi-Fi antenna.
 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 25dB isolation
is recommended.
 To avoid negatively impacting TX power and receiver sensitivity, do no cover the antennas with metallic
objects or components.
 Opening/handing/removing must be done on an anti-ESD treated workbench.
All workers must also have undergone anti-ESD treatment.
 The devices should be mounted within one year of the date of delivery.
