BeneVision N1 Patient Monitor Operator’s Manual A - 9
■
The distance between the interfering devices and the monitor is greater than 20 cm. A Wi-Fi interference
(no greater than -85 dBm) in the same channel and a Wi-Fi interference (no greater than -50 dBm) in an
adjacent-channel are presented synchronously. The interfering devices include, but are not limited to, 2.4 G
wireless devices, cellular mobile networks, microwave ovens, interphones, cordless phones, and ESU
equipment. The interfering devices do not include Wi-Fi devices.
A.13.2.2 Wi-Fi network stability
The ratio of the communication data lost on CMS from the N1 does not exceed 0.1% in 24 hours..
Testing conditions are as follows:
■ Number of the monitors supported by a single AP: ≤16.
■ Each monitor can communicate with the central monitoring system.
■ Two monitors are used to view other monitors.
■ Only one monitor can transmit history data.
■ The weakest strength of the AP signal where the monitor is located cannot be less than -65 dBm.
A.13.2.3 Distinct vision distance
The distinct vision distance between the monitor and the AP is no less than to 50 meters.
A.14 Measurement Specifications
The adjustable range of alarm limits is the same with the measurement range of signals unless otherwise
specified.
