IntelliVue Wireless 802.11 Solution
Technical Data Sheet
Description
IntelliVue Patient Monitors using 802.11 can coexist
with other wireless devices such as VoIP phones and
mobile appliances on a customer’s enterprise
WLAN. A robust and high availability WLAN is
required to support the physiological waves,
parameters and alarms transmitted from IntelliVue
Patient Monitors.
Features
• Leverage existing hospital WLAN
• Operate on 802.11 a/b/g networks
• Utilize advanced encryption and authentication
including WPA2-PSK and WPA2-Enterprise
• Enable wireless QoS with support for WMM
(Wireless MultiMedia)
Planning and Preparing Your Network
The following are important considerations when planning and
preparing the hospital network for a patient monitoring system:
• Discuss expectations and requirements with the clinical users for
physiological monitoring.
• Involve information technology staff early to align wireless strategy
and decisions and prepare for any potential updates to the wireless
network to support a patient monitoring system.
• Review the IntelliVue Customer-supplied Clinical Network (CSCN)
Specifications.
Service Offerings
Philips offers a variety of wireless networking and product-related
services for the IntelliVue Patient Monitoring solution based on Philips
strong experience with deploying life critical clinical systems.
For customers that want to use their enterprise WLAN on which to
run Philips 802.11 IntelliVue Patient Monitors, Philips requires a radio
frequency (RF) survey to identify whether the network can support the
robust requirements of life critical data. Philips can review an existing
RF Survey for compliance with the Philips specification.
Philips networking services include:
• Network design consultation
• Verify that the current or planned hospital infrastructure complies
with the Philips approved 802.11 vendor models and software
versions.
• Determine coverage area, including in-room bathrooms, corridors
and transport areas.
• Complete an RF site survey to verify that all Philips RF requirements
are met.
• Assess compatibility requirements among wireless solutions to avoid
coexistence issues.
• Agree on change control, maintenance and management
responsibilities among biomedical engineering and information
technology staff.
• Consider hospital policies, procedures and standards for wireless
medical devices including safety, security and privacy.
• Perform risk assessment for connecting wireless medical devices to
the hospital network.
•Network evaluation
•Radio frequency site survey
• Remote go-live assistance
