Psion Omnii Hand-Held Computer User Manual
G.1 Wireless WAN
The Omnii is available with one of the following Wireless WAN (WWAN) radio options: the Cinterion MC75i
EDGE and the Cinterion PH8-P HSPA+. An Omnii Hand-Held Computer equipped with a GSM/GPRS radio
has wide area networking capabilities. With either of these radios and a SIM card, you can wirelessly trans-
fer data, and you use the Omnii voice option to place phone calls.
G.1.1 Taskbar Icons
Wireless WAN icons in the taskbar indicate the status of your wide area network connection. Note that
these icons are only visible when the relative radio is installed in the computer, and the interface is enabled.
The following taskbar icons are used:
• G - GSM/GPRS
• E - GSM/EDGE
• 3G - UMTS 3G
• U - UMTS/HSPA+
User interaction is required (e.g. the user is required to enter a PIN).
A non-recoverable (fatal) error has occurred.
The modem status is unknown or the modem is not connected to any network (the signal strength is 0%).
The modem has found a network, and the signal strength is between 1% and 20%.
The modem has found a network, and the signal strength is between 21% and 40%.
The modem has found a network, and the signal strength is between 41% and 60%.
The modem has found a network, and the signal strength is between 61% and 80%.
The modem has found a network, and the signal strength is between 81% and 100%.
Once the modem detects that a packet data service is available, a letter is added to the signal strength icon
indicating the kind of packet data service. Keep in mind that the signal strength icon is displayed without a
letter if packet data service is not available, or if it is available but not yet initialized.
For example:
The modem has found a network, the signal strength is between 41% and 60%, and GSM/GPRS packet
service is available.
The signal strength icon is replaced by a connection indicator icon when a packet data connection is
started:
A GPRS packet data connection is active.
In addition to the signal strength or connection indicator a second icon may be shown.
A new SMS (Short Message Service) message has arrived.
The dialer icon is displayed when the Voice option is available (SIM card and GPRS radio are installed).
When you have an active call, this icon flashes yellow, and then green.
G.1.2 Establishing a Packet Data Connection
To display the main Wireless WAN dialog box:
• Double-tap on the Wireless WAN icon in the taskbar.
If the icon is not visible in the taskbar, the radio interface has been shut down or the modem has been re-
moved:
• In the Control Panel , choose the Wireless WAN icon.
