25. Information of QoS

The data transmission between the Luna G3 BPAP 25A with a Cellular Module and
iCodeConnect is a daily transmission. The Cellular Module transmits the following
®
four types of data: Therapy summary data in a defined period, compliance data,
system settings, and device information.
This process is not real time communication.
The size of the data transmitted to Cellular Module per second is no more than 1k in
normal condition, and no more than 1M within 8 hours per night.
Acceptable latency
As the user information is not viewed by the doctor in real time, sometimes it can be
delayed for 24 or more hours.
Acceptable level of probability for loss of information within the network
The data has little effects on treatment effectiveness. These are key data, and their
integrity should be ensured, but they do not involve real-time control of therapeutic
medical devices, and do not rely on network quality.
Wrong transmission of the information described in sections above data will be
abandoned based on a checking mechanism, and correct data will be sent
continuously until received completely.
The data transmission protocol between the module and the server includes
unpacking information and ID value, which ensure the completeness of the data
transmission.
Signal priorities of the network
The therapy device itself does not have high-priority medical device alarms, and its
treatment of patients does not rely on wireless communications.
Based on the above analysis, the Cellular Module has low requirements for QoS.
