4.3.4 W30 InterRAT and Frequency Hopping
Handover between the UMTS (3G) and the GSM/GPRS/EDGE (2G)
networks is automatically managed by the Ericsson W30.
4.4 RSCP Alarm Threshold
For RSCP (Receive Signal Code Power) an alarm threshold can be set and
if the current RSCP level is below the threshold value, a critical event is
sent to the syslog.
4.5 Set Time/Date from Mobile Network (W35 only)
The system time and date in the Ericsson W35 can be configured to be set
from the mobile network. When the celltime service is initially enabled it
checks and updates the time every 2 minutes for the first 20 minutes. After
that, the synchronization occurs every 15 minutes.
As an alternative, and used for the Ericsson W30, synchronization can be
done with a remote NTP server (see section 5.2.7).
4.6 Security
The basic security feature of the Ericsson W3x is the same as any GSM
phone, using a PIN code that comes with the subscription SIM card. The
PIN code is simply entered via the WUI or via phone handset (W35 only).
To simplify usage, the Ericsson W3x has an auto PIN feature that requires
the PIN code only to be entered the first time the unit is used or upon
changing the SIM card.
Additionally the Ericsson W3x provides security features that prevent
unauthorized use of the SIM card and the unit, which can be customized if
required.
4.6.1 PIN Lock
This feature locks the SIM card to a unique unit by changing the PIN code
to a new random value. As a result, the SIM card cannot be used in another
device unless the PUK code is known.
