Improve the user experience with wireless coexistence testing

Regardless of the technology, wireless coexistence testing aims to maximize receiving system performance in complex electromagnetic environments. Typically, performance quality is defined using data link physical layer parameters, such as packet error rate (PER), bit error rate (BER), block error rate (BLER) or data throughput.

In order to assess the performance of the overall system, application layer performance indicators such as audio and video quality need to be considered along with the physical layer. Receiver desensitization or blocking, for example, caused by adjacent channel interference is a common problem that degrades system performance and user experience. Wireless coexistence tests are performed in an electromagnetic environment that is similar to the environment in which a receiver operates to detect vulnerabilities in the design.

In the past, the introduction of regulations was very ad hoc, particularly for coexistence issues between devices sharing unlicensed frequencies or devices with applications that appear to have …
