4.2 External connections

4.2.1 GSM antenna connector
An SMA "ANT" input is used to connect external GSM/UMTS/LTE antenna. To establish
a connection with a GSM/UMTS/LTE network, an external antenna must be used. Type of
antenna depends of GSM/UMTS/LTE coverage. In good circumstances (level of received
signal is high) use antenna contained in the package. If the range of GSM/UMTS/LTE is
low or none, an outdoor or indoor (for instance in place where GSM/UMTS/LTE range is
sufficient) antenna should be used.
Note: If there is no antenna connected to SMA connector, the connection with
GSM/UMTS/LTE network is impossible.
4.2.2 GNSS antenna connector
An SMA "GNSS" input is used to connect an external GPS/Glonass antenna. To
establish connection with GPS/Glonass sattelites and check the coordinates of the device,
an external antenna must be used and should be located outdoors. GNSS is optionally
available in RB900SG-L2 and RB900SG-L5 modem variants.
