Abstract
Simplified data message terminals and data communicating voice terminals are described for providing additional functionality in a facility using a wireless data communication system. The simplified data message terminals provide message and paging communication to employees or customers in a simplified terminal configuration using the existing data communication system. By performing voice to data and data to voice conversions, the same system provides voice communication without interruption of data communication services.

15. A system for scanning, comprising:
-
(1) at least one mobile scanning unit, each comprising;
(a) a scanner for scanning optical codes;
(b) a radio module;
(c) a display;
(d) an annunciator;
(e) a power source and a power manager;
(f) a plurality of memory elements; and
(g) a plurality of user-depressible buttons;
(2) a wired network; and
(3) at least one access point;
wherein the at least one access point is capable of transmitting transmission data from the wired network to the at least one mobile scanning unit via a wireless medium and receiving reception data from the at least one mobile scanning unit to the wired network via a wireless medium;
wherein the at least one access point forms a transmission area, the transmission area including the space where association to the at least one access point is possible by the at least one mobile scanning unit; and
wherein the at least one access points broadcasts a periodic beacon via wireless medium; and
wherein each of the at least one mobile scanning unit attempts to associate with the at least one access points by broadcasting a poll via a wireless medium on a first periodic basis unless otherwise instructed by the power manager within the at least one mobile scanning unit. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
