BeneVision N1 - 3.5 Using the Patient Monitor to Evaluate Network Coverage

3-7
SN Item Requirements Verification Method Check Result
The required bandwidth is 6.14
Mbps.
Important settings
1 DHCP The DHCP server needs to reserve
enough IP addresses to ensure
that the patient monitor can
obtain the IP address.
Check if this requirement is satisfied together with
the IT department of the hospital.
2 IGMP snooping If the patient monitor adopts
multicast, the IGMP snooping
function is enabled.
Check if this requirement is satisfied together with
the IT department of the hospital.
3 Multicast If the patient monitor adopts
multicast, the network multicast
function should be enabled.
Check if this requirement is satisfied together with
the IT department of the hospital.
4 Beacon and
DTIM
AP DTIM = 1, Beacon = 100
milliseconds
Check if this requirement is satisfied together with
the IT department of the hospital.
5 Service port Refer to the white paper of the
Mindray patient monitor network.
The patient monitor requests
opening some TCP/UDP ports.
Check if this requirement is satisfied together with
the IT department of the hospital.
6 Qos It ensures that Mindray monitor
data has the highest priority.
Check if this requirement is satisfied together with
the IT department of the hospital.
3.5 Using the Patient Monitor to Evaluate Network Coverage
To confirm the coverage effect, perform the coverage test in the area where the patient often goes.
Observe the RSSI displayed on the patient monitor. Check whether any offline event occurs and whether the coverage
meets the requirements.
When necessary, adjust the AP location or add APs to ensure the coverage effect.
Do as follows:
1. Set the patient monitor to access the central monitoring system.
2. Enter "ping –t –l 32 –w 1500 IP address" in the CLI window of the central monitoring system to ping the patient
monitor (continuously ping the patient monitor; the packet consists of 32 bytes, and the reply timeout is 1500
milliseconds). Press "Ctrl+C" (end Ping) 10 minutes later. Make sure that the average delay is less than 250
milliseconds, and the packet loss rate is less than 1%.
3. Hold the patient monitor lest it would be blocked by others. Walk aroundin the expected coverage areas (such as all
corners of wards, toilets, smoking areas, corridors, and elevators).
4. Check that the number of disconnections from the central station is less than 10% of the number of patient monitor
roaming times, and the RSSI value displayed on the patient monitor is not less than -65 dBm.
5. If the RSSI value is ever less than -65 dBm when you walk about, stop at this position and perform observation for
30 seconds. If the RSSI value is not less than -65 dBm in 66% of the time, the coverage requirements are met.
