WIRELESS MESH POINT PORTABLE DATA TERMINAL
First Claim
1. A terminal comprising:
- a terminal module comprising an encoded information reading device and a first battery, wherein the terminal module manages its power between at least an awake state and a sleep state and sends outgoing Media Access Control frames to a mesh point module;
the mesh point module communicatively coupled to the terminal module for providing distribution and integration services over a wireless mesh network comprising at least two other terminals, wherein the mesh point module is configured for;
receiving a Media Access Control frame;
while the terminal module is in the awake state or the sleep state, in response to receiving a Media Access Control frame addressed to a recipient in the wireless mesh network, delivering the Media Access Control frame using the distribution services;
while the terminal module is in the sleep state, in response to receiving a Media Access Control frame addressed to a recipient outside the wireless mesh network, delivering the Media Access Control frame using the integration services;
in response to receiving an outgoing Media Access Control frame from the terminal module addressed to a recipient in the wireless mesh network, delivering the Media Access Control frame using the distribution services;
in response to receiving an outgoing Media Access Control frame from the terminal module addressed to a recipient outside the wireless mesh network, delivering the Media Access Control frame using the integration services; and
in response to receiving a Media Access Control frame addressed to the mesh point module, transmitting the Media Access Control frame to the terminal module.

Abstract
A portable data terminal (PDT) adapted to participate in a wireless mesh network including a plurality of peer PDTs can comprise: a PDT module including an encoded information reading (EIR) device, and a mesh point (MP) module communicatively coupled to the PDT module. 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.
