Test or Observation Item Result (Pass, Fail or NA)
Execute the Ping command on the central monitoring system for the patient monitor.
Make sure that the average delay is less than 250 milliseconds, and the packet loss rate is
less than 1%.
Hold the patient monitor to walk around in different AP scopes. Observe the continuous
waveform on the central monitoring system after walking about in the entire expected
coverage area. The offline event time should be less than 10% of the patient monitor
roaming time.
At the position with the worst coverage effect, the RSSI value on the screen is higher
than -65 dBm.
If the evaluated monitor has a fixed position and does not roam between APs, the test of walking in the
coverage area is not required. You only need to place the monitor at the position with the worst signal
where it may be installed, and then confirm the RSSI and ping effect.
