Dynamic Mode
In “Dynamic Location” mode, the NITX can move around the coverage area and speech will be
automatically directed to the current location of the NITX when a call is received.
The real-time location of the NITX is determined by LF beacons (NILF) mounted at the entrance to each
room. The NILF transmits an LF location signal which is received by the NITX. The NITX memorizes its’
current location until it receives a new LF location signal. The memorized (last known) location
information is included in all transmissions from the NITX. The telephone number to be called is
automatically updated to the current location of the NITX with each call received so the speech response
will be sent to the telephone number of the NISP at the location of the call.
Figure 171. Wireless nurse call example with speech - dynamic mode
The example consists of three room controllers (NIRC3). Each NIRC3 includes a voice piggyback module
(NIVP) and two NIRC3s include a transceiver module (NIRX). There are five corridor lamps and each room
has a doorside module (NIDM) combined with a speech module (NISP).
At the door to each room an active LF location beacon (NILF) is mounted. The active LF location coverage
(green area) includes the door to the room. The two main entrance doors have a passive location beacon
(NILF) and a card reader module (NICR) for access control (yellow area).
8.3.2 NILF Beacon Modes
The LF beacon (NILF) can be configured as a “Passive” beacon or an “Active” beacon using DIP switches
situated in the NILF housing (as described in
).
Passive Location Beacon
When passive mode NILF beacons are used the NISP telephone number will not be updated if the NITX
subsequently moves between passive locations after a call is received. The speech location will remain at
the location where the call was first received.
Active Location Beacon
When dynamic mode NILF beacons are used the NISP telephone number will be updated and the speech
location will change to the new location if the NITX subsequently moves between passive locations after
a call is received.
