General ITS Infrastructure Site Planning Guidelines

Patient bedside monitors and patient-worn transceivers with a wireless network
connection have their advantages, however the flexibility the wireless link offers is
not without its challenges. The reliability and quality of the wireless signal
transmission through the air and hospital walls are governed by a number of
variables that can be difficult to control. A wireless network connection from a
patient monitor or patient-worn transceiver cannot be as dependable as a wired
network connection.
The effect of low signal strength and interference on the display of the patient
information from a wireless patient monitor at the Information Center can range
from a momentary data loss to a lengthy period of data loss. Although data loss due
to the wireless link may be occurring at the Information Center, monitoring and
alarms continue at the patient monitor. Note however, if the wireless link to a
patient-worn transceiver is lost, patient monitoring terminates.
Before installing the IntelliVue Telemetry System as part of an ICN deployment, you
must complete the following site planning tasks:
• Perform a physical space assessment.
-
-
-
-
-
-
-
• Define the number of Uninterruptible Power Supplies required to support the
ITS installation.
• Define the Sync Unit Network required to support the number of APs to be
installed.
• Plan your AP Groupings.
• If you are installing the 2.4 GHz ITS, perform an RF assessment.

Define the desired coverage area within the hospital.
Determine how many patient-worn transceivers and wireless bedside
monitors are required.
Apply radius-of-coverage circles to the site floorplan to define optimal AP
installation locations.
Add additional APs to cover other high-density wireless client areas if
needed.
Determine the number of Access Point Controllers required to support the
installation.
Evaluate the availability and location of equipment rooms and possible
locations for Switches, APCs, PoE Units and Sync Units.
Specify the cable runs between ITS infrastructure devices.
Understand RF co-existence issues in the hospital environment.
Determine available channels. Use a spectrum analyzer tool to identify RF
channels in use and possible interference. Capture and store the spectrum
analysis data.
Assign channels to APs to avoid co-channel interference.
