WWAN Connections

Kyman™ GSM/GPRS/EDGE models enhance your connectivity solutions giving you
an opening to an international wireless infrastructure that is the standard in Europe
and Asia.
GSM (Global System for Mobile communications), is a digital mobile phone system
based on TDMA; it utilizes the 800, 900, 1800 and 1900 MHz bands.
GPRS supports IP (Internet Protocol) and allows accessing Internet and Intranet
services, such as sending and receiving e-mail or Web browsing.
In order to use a WWAN Connection you have to install a SIM Card (see instructions
on the following page).
In order to avoid wasting energy, the GSM/GPRS module is off by
default. If you need to have GSM/GPRS working, the module must be
powered on using the Wireless Communications applet (see par.
3.7.4.)
NOTE
Suspending the terminal powers off the GSM/GPRS 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
NOTE
connection must be manually re-initialized.
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.
In case of vehicle cradle installations, a good habit is to install the
NOTE
external microphone to minimize the risk of noises and echoes.
If the coverage is poor, in case of continuous communication, some
degradation of the barcode reading capabilities can be experienced.
