<p>Two or more communications applications are executed on a shared processing platform to process signals received from and transmitted to wireless devices according to a communications protocol, the shared processing platform having shared hardware resources including memory and at least one data processor. A security mechanism is provided to enable each communications application to have independent control of access to data and configuration settings that are private to the communications application. Compatibility of hardware configuration settings associated with different communications applications is determined, and conflicts between hardware configuration settings associated with different communications applications are mediated.</p>
