CARESCAPE Monitor B650
Documentation about the Wireless LAN infrastructure:
•
GE WLAN pre-quote questionnaire with all applicable attachments.
•
Wireless LAN design documentation, including site survey results.
Test plan
Each wireless installation is unique. As it is often impractical and uneconomical to verify the
whole wireless coverage area and all the installed access points, prepare a site specific test
plan that covers the areas that are most likely to encounter issues with the wireless
communication.
Utilize the information provided in the pre-quote questionnaire, existing design documentation
and site survey results, and discuss with the hospital IT specialists and clinical staff to identify
the areas that are the riskiest for poor wireless communication, and prepare a test plan
accordingly.
Take into account the following aspects when preparing a test plan.
•
Identify areas with known or obvious low signal strength.
•
Identify areas with known sources of radio frequency interference, causing high noise
floor and/or poor signal-to-noise ratio.
•
Identify the special characteristics in the building layout (floors, wings patient rooms) and
construction material used.
•
Identify the time and areas of congestion, with high number of wireless clients and a lot of
network traffic.
•
Identify intended clinical workflow paths, including bedside locations and transport
routes.
Prepare the test plan by documenting the intended walking path and test points to the floor
plan, preferably to copy of a site survey document that shows the wireless coverage area, the
location of wireless access points, signal strengths and sources of known radio frequency
interferences.
NOTE: In the sample floor plan below, EG1- EG20 represent possible test points. Take into
account in your plan that some rooms and areas may not be accessible at the time of
performing the survey.
