Communication network terminal with sleep capability

摘要: Improved apparatus for a radio communication system having multiplicity of mobile transceiver units selectively in with plurality base which, turn, communicate one or more host computers storage and manipulation data collected by bar code scanners other collection means associated the units. A network controller an adapter which has simulcast sequential mode provide selective interface between transceivers. scheme routing through is also disclosed wherein intermediate stations are organized into optimal spanning-tree to control from RF terminals computer efficiently dynamically. Additionally, redundant protocol utilizes polling under heavy loaded conditions, requires that roaming terminal wishing initiate must first determine channel truly clear listing entire interpoll gap time. In further embodiment, criterion used attaching given station reduces conflicts overlapping regions adjacent stations.
