US Patent 7346017 Partially integrating wireless components of processor-based systems

A capability may include a pair of functions, one of which is integrated into a platform and the other of which is only available through an add-in card. A mating manager may determine whether both functions are available and if so, coordinate the operations of those functions. As a result, platforms may be released with the capability to be augmented thereafter by those users who choose to provide the add-in cards needed to implement the capability. A wireless network capability may be partially integrated into platforms, with additional components needed to actually implement the wireless capability provided through add-in cards. The add-in card may perform wake packet filtering to avoid excessively awakening the platform.
