Abstract:
1. A portable data terminal adapted to participate in a wireless mesh network including a plurality of peer portable data terminals, said portable data terminal comprising: a housing; a portable data terminal disposed within said housing, said portable data terminal module including a central processing unit, a memory, and at least one encoded information reading device configured to output a decoded message data corresponding to an encoded message; and a mesh point module disposed within said housing, said mesh module communicatively coupled to said portable data terminal module, said mesh point module including a microcontroller and at least one wireless communication interface; wherein said mesh point module is configured to perform IEEE 802.11-conformant wireless station services, and IEEE 802.11-conformant wireless distribution system services including distribution and integration; wherein said portable data terminal module employs a power management scheme for controlling power management states of said portable data terminal module at least between an awake state and a sleeping state; wherein said mesh point module is further configured, responsive to receiving, while said portable data terminal module is in a state selected from the group consisting of: said awake state and said sleeping state, a Media Access Control frame addressed to a recipient inside said mesh network, to deliver said Media Access Control frame using said distribution service; wherein said mesh point module is further configured, responsive to receiving, while said portable data terminal module is in said sleeping state, a Media Access Control frame addressed to a recipient outside of said mesh network, to deliver said Media Access Control frame using said integration service; wherein said portable data terminal module is further configured to send outgoing Media Access Control frames to said mesh point module and said mesh point module is further configured to route outgoing Media Access Control frames obtained from said portable data terminal to recipients inside said mesh network utilizing said distribution service and to recipients outside said mesh network utilizing said integration service; and wherein said mesh point module is further configured to obtain incoming Media Access Control frames addressed to said mesh point module and transmit said incoming Media Access Control frames to said portable data terminal module.
