Cellular System
This field displays the type of the network to which the ZyWALL is connected. The
network type varies depending on the 3G card you inserted and could be UMTS,
UMTS/HSDPA, GPRS or EDGE when you insert a GSM 3G card, or 1xRTT, EVDO
Rev.0 or EVDO Rev.A when you insert a CDMA 3G card.
Signal Strength
This displays the strength of the signal. The signal strength mainly depends on the
antenna output power and the distance between your ZyWALL and the service
provider’s base station. You can see a signal strength indication even when the
ZyWALL does not have a 3G connection (because the signal is still there even
when the ZyWALL is not using it).
Signal Quality
This displays how good or bad the signal’s strength is based on it’s strength. For
example, “Good” and four signal icon bars display for a signal strength of “-80
dBm”.

serial number of a CDMA 3G card and is similar to the IMEI on a GSM or UMTS 3G
card.

This displays the International Mobile Subscriber Identity (IMSI) stored in the SIM
(Subscriber Identity Module) card. The SIM card is installed in a mobile device and
