GSM antenna connector
An SMA antenna input is used to connect an external GSM antenna. To establish a
connection with a GSM network, an external antenna must be used. Type of antenna
depends on the GSM coverage. In good circumstances (level of received signal is high)
use the antenna supplied in the package. If the range of GSM is low or none, an outdoor
or indoor (for instance in a place where GSM range is sufficient) antenna should be used.
Note: If there is no antenna connected to the SMA connector, connection with a GSM
network is impossible.
