LABEL | DESCRIPTION |
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 |
| dBm”. |
