Chapter 1: Overview
4. When the packet arrives at the ITS Access Point, the Access Point "unwraps" the
message, determines which transceiver the message is intended for, and sends
the message on to the transceiver over the wireless link.

Defined ITS Bandwidth

The ITS transceivers (portable patient-worn devices), wireless bedside monitors,
and infrastructure operate on the 1.4 GHz US Wireless Medical Telemetry Service
(WMTS) band or on the 2.4 GHz band for deployments outside of the US.

1.4 GHz ITS Bandwidth

In the United States, the IntelliVue Telemetry System operates in the radio bands of
1395 – 1400 MHz and 1427 – 1429.5 MHz. The FCC has designated this spectrum
(WMTS) for use by Medical Telemetry devices.
WMTS operations are accorded primary status over non-medical telemetry
Standard WMTS
Channels operations in 1395-1400MHz and 1427-1429.5 MHz bands, but under certain
extenuating circumstances, medical telemetry may also be permitted to operate in
the 1429.5 - 1432 band. Table 1-5 lists the standard 1.4GHz WMTS channels.
The FCC has carved the following metropolitan regions out of the standard WMTS
Carved-out
Areas spectrum to protect operation of critical RF devices (e.g., radar, military and
government communications, etc.):
• Pittsburgh, PA
• Metro Washington D.C.
• Richmond/Norfolk, VA
• Austin/Georgetown, TX
• Battle Creek, MI
• Detroit, MI
• Spokane, WA
In these seven areas, in contrast to the rest of the US, WMTS has primary status in
the 1429-1431.5 MHz band, but is secondary to non-medical telemetry operations
