The MP module can include a microcontroller and at least one wireless communication interface and can be configured to perform IEEE 802.11-conformant wireless station services including authentication, de-authentication, privacy, and MAC service data unit delivery, and IEEE 802.11-conformant wireless distribution system services including association, disassociation, distribution, integration, and re-association. The MP module can be further configured, responsive to receiving a MAC frame addressed to a recipient inside the wireless mesh network, to deliver the MAC frame using the distribution service. The MP module can be further configured, responsive to receiving a MAC frame addressed to a recipient outside of the wireless mesh network, to deliver the MAC frame using the integration service. The MP module can be further configured to route an incoming MAC frame according to its destination address and the frame control field. The MP module can be further configured to cause the PDT module to exit said sleeping state responsive to receiving a mobile management software (MMS) wake-up command.
