Wireless LAN A-1
Appendix A Wireless LAN
The system provides wireless net adapter configuration, so as to assist information query and unlimited
network service.
It is prohibited to use the wireless LAN function in an
airplane, as this may violate the relevant provisions in
the aviation regulations.
Use the wireless LAN function prudently in emergency
ambulances (or other vehicles) as other devices or
communication signals may be interfered with.
Use the wireless LAN function prudently in
OR/ICU/CCU as it may interfere with other devices.
When the wireless LAN function is turned on, the
ultrasound system may suffer interference from other
equipment, even if that other equipment complies with
CISPR EMISSION requirements.
Keep at least 20 cm away from the ultrasound system
when the wireless LAN function is in use.
For a better wireless LAN transmission effect, please take the following settings:
SSID>80% with stable WLAN network;
Wireless router and the server are in the same network segment;
Router setting:
Wireless standard 802.11n
Maximum transmission speed ≥300M
Use AP (access point) setting;
Number of the devices connected to the same router ≤5.
Target server setting:
Network is stable and not under overloading state (e.g. high CPU/memory
usage, fast HDD speed, limited HDD space);
Level other than the highest level of firewall is adopted;
Operating system is Win8 or higher versions and supports a Gigabit Ethernet.
Disconnection may be caused if the devices connected excess the router capacity (please
refer to settings of the router, generally it should be ≤5.)
DO NOT connect devices other than specified into the LAN.
Medical devices within the same LAN may interfere with each other, the operator should be
cautious. (Do not connect devices that may cause strong interference. For example, life-
supporting devices should not be connected in the same LAN.)
Other non-medical devices in the same frequency band may cause interference, please be
cautious.
