The rear panel accommodates the LANCOM UMTS Router's connectors:
Aux connector for a mobile-telephony or GPS antenna.
If the Aux connector is being used for mobile telephony a diversity
antenna is connected to the benefit of signal quality.
If GPS location determination is to be used, a GPS antenna is connec-
ted to the Aux connector.
A GSM/UMTS/GPS combi antenna can be connected to the Aux con-
nector, if GPS is used for location verification for a short while only. As

function is available again and the GPS module is switched off auto-
matically.
