8 INTEGRATION GUIDELINES
The following is a list of RF layout design guidelines and recommendation when installing a Laird module into
your device.
 Do not run antenna cables directly above or directly below the module.
 If there are other radios or transmitters in the device (such as a Bluetooth radio), place the devices as far
apart from each other as possible.
 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.
