DESCRIPTION
This field displays what type of cellular network the 3G connection is
using. 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.
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.
