3.6 WWAN CONNECTION
Elf GSM models enhance your connectivity solutions giving you an opening to
an international wireless infrastructure that is the global standard.
GSM (Global System for Mobile communications) is a digital mobile phone
system based on TDMA; it utilizes the 850, 900, 1800 and 1900 MHz bands.
In order to use a WWAN Connection you have to install a SIM Card
∗
(see
instructions on par. 1.5).
NOTE
In order to avoid wasting energy, the GSM module is off by
default. If you need to have GSM working, the module must
be powered on using the Wireless Communications applet
(see par. 4.7.2).
NOTE
Suspending the terminal powers off the GSM radio and drops
the connection. When the terminal resumes, if the connection
was managed by Microsoft Internet Explorer, it is
automatically restored, otherwise, the radio connection must
be manually re-initialized.
NOTE
The GSM voice capability of this mobile computer has to be
addressed to occasional use, in well covered areas.
If the coverage is poor, the voice quality can be highly affected.
NOTE
Calls can be made or received using the Elf as a phone handset,
by the Elf headset or by a Bluetooth® headset.
