Note
Please be aware that the measured performance values were determined in the free field without significant interference or signal dampening.
The maximum range, latency and the possible message throughput may vary considerably depending on the environmental influences, setup condition, the used antennas and, if applicable, the hardware installed for the Wi-Fi infrastructure.
Please consider these values just as approximate reference values which can be achieved in a specific test setup under ideal conditions.
It is the system integrators responsibility to verify the connection stability and performance under real ambient conditions as part of the final application and setup.
When designing the application and programming the control unit, it is important to ensure that certain latency times and connection interruptions are tolerated by the control and treated accordingly.
An end-to-end monitoring of the message transmission is recommended in any case.
Please note that the quality of the radio connection depends largely on external influences and cannot be guaranteed at any time.
It is therefore essential to provide appropriate error handling in the application for any delays or connection interruptions.
