3-8 TM80 Telemetry Monitor Service Manual
3.2 Network Requirements of the TM80
The TM80 transmits vital signs of patients in real time. The requirements for
real-time and reliability are higher than those for audio and video services. The TM80
is powered by a battery. It adopts low power Wi-Fi technology. Therefore, the
network needs to meet specific requirements to ensure reliable operation.
The network requirements of TM80 can be classified into six types:
Wireless coverage
AP capability and compatibility
WLAN features
EAP Requirement for RADIUS Server and Certs
Network service and VLAN
Some important settings of network device
The first four types are decided by infrastructure of network. They can’t be modified
easily. If the network does not meet the requirements before TM80 is installed,
network dropping-off may happen easily after installation.
The fifth and sixth types belong to configuration of network. They need hospital IT
department’s help to achieve. According to experience of Mindray, the two types
can guarantee reliable performance of TM80 effectively. If any requirement is not
met, network dropping-off may happen in certain situation. If the number of
devices using the same network is small, and no device needs high wireless
bandwidth, the possibility of dropping-off can be reduced.
