(5) For client devices that have software configuration control to operate in different modes (active
scanning in some and passive scanning in others) in different bands (devices with multiple equipment
classes or those that operate on non-DFS frequencies) or modular devices which configure the modes
of operations through software, the application must provide software and operations description on
how the software and / or hardware is implemented to ensure that proper operations modes can not
be modified by end user or an installer.
