<P>PROBLEM TO BE SOLVED: To provide a data collection device having dynamic access to multiple wireless networks. <P>SOLUTION: A data collection device incorporating an encoded information reading unit operates within a system including an access point that is wireline connected to each other. The encoded information reading unit includes at least one of a bar code reading unit, an RFID tag reading unit and a credit/debit card reading unit. Further incorporated in the data collection device is a dynamic access module. The dynamic access communication module enables the data collection device to participate in a self-organized network that supports multi-hop data packet transmissions between data collection devices and further enables the device to transmit data received from a peer device to the system access point. <P>COPYRIGHT: (C)2007,JPO&INPIT |
