Wideband and Narrowband Channel Coordination and
Deployment
When using both wideband and narrowband telemetry transmitters
in the same antenna system, wideband and narrowband channel
conflicts must be avoided:
•
Using any wideband channel will automatically exclude the use
of three narrowband channels.
•
Using a narrowband channel will automatically exclude the use
of one or two wideband channels.
Example 1, wideband and narrowband channel allocation/
deployment for 600-MHz transmitters:
When using a model 90347-05 transmitter on channel 2242, or a
90343-05 transmitter on channel 2242, you cannot use or deploy a
90341-05 transmitter set to channel 1241, 1242, or 1243.
Example 2, wideband and narrowband channel allocation/
deployment for 1400-MHz transmitters:
When using a model 91347-09 transmitter on channel 2002, or a
91343-09 transmitter on channel 2002, you cannot use or deploy a
91341-09 transmitter set to channel 1001,1002, or 1003.
Prior to assigning new narrowband or wideband channel numbers,
all institution channel numbers and transmitter types must be
identified, including spares. If there is insufficient space (because of
many small gaps in current channels) to add the desired new
channels, re-channelization may be required. For more information,
contact your Spacelabs Healthcare field service engineer.
27 to determine where wideband and narrowband channels overlap.
Note:
Wideband channel 2480 is not used because it falls outside of
the 608-614 MHz spectrum by 12.5 KHz.
