For hardware versions older than version 1.4, in case a Wi-Fi connection is needed, connect a Wi-fi antenna to the SMA connector labeled “WIFI“. Select a good antenna placement spot considering the operation environment.
Newer hardware versions don’t have an option of connecting an external Wi-Fi antenna as MIMO capability for cellular modems has been introduced. In case stronger reach is needed, a user should contact the manufacturer to provide possible solutions.
Given that the default hardware configurations are set for GSM on connectors ANT 1 and ANT 2, the Wi-Fi antenna shall remain non-operational in versions exceeding 1.3. Users are advised to contact the manufacturer before purchasing the product if Wi-Fi functionality is required.
Make sure the signal level is over -80dBm to have a stable connection to the network.
