5.3 DECT Features
5.3.1 Mobility Management Function
Hand-Over
Once a call has been made, it is still necessary to change physical channels without release of the
call. Frequency band or time slot can be changed due to quality degradation or interference, the
associated base stations can be changed due to the mobility of a user in a multi-cell environment.
Out of Range Indication
If the wireless terminal is getting too far from the base
station to which it locks, then soft mute is occurred and
warning tone will be heard once during a call or in an idle
state. Then, “OUT RANGE” message is displayed on the
LCD as the left.

To maintain a call, move closer to the base station. Bear in mind that walls, buildings, and
especially large metal surfaces have strong screening effects.
When pressing

button in out of range, the wireless terminal generates 1 beep with
“OUT RANGE” message on the LCD and goes to an idle state.
Pressing

button is ignored in state the wireless terminal is not locked.
Call-Drop Warning Indications
Apart form the above out of range indication, there are two more indications to warn call-drop.
Radio interference: When a cell is fully occupied and there is sudden heavy radio interference,
one call is dropped and three beeps will be heard with no message.
Entering fully occupied range: When a user is moving to a fully occupied cell, one beep is
heard with no message with two seconds interval. The closer to the cell, the more unstable the
call is. Try to move toward other cell.

sequence to reply to the authentication. The authentication is requested by an attendant and the
wireless terminal should have its authentication code (password) to answer the request. Refer to
