Data collection device having dynamic access to multiple wireless networks
First Claim
1. A data collection device for incorporation in a data collection system having an access point and a peer device, said access point adapted for wireline connection to a wireline bus, said data collection device comprising:
- an encoded information reader unit selected from the group consisting of a bar code decode unit, an RFID reader unit, and a credit/debit card reader unit;
a radio transceiver for wireless transmission of data packets;
a housing, wherein said encoded information reader unit is supported within said housing, wherein said housing is one of a hand held housing and a re-mountable housing; and
a dynamic access module enabling said data collection device to perform at least one of receiving data packets from said peer device and transmitting data packets to said peer device;
wherein said data collection device is operative to continuously perform switching between an infrastructure mode and an ad-hoc mode;
wherein said data collection device is operative so that at least one of receiving data packets from said peer device and transmitting data packets to said peer device is carried out with a single hop transmission when said switching of said data collection device and a switching of said peer device is synchronized; and
wherein said data collection device is further operative so that at least one of receiving data packets from said peer device and transmitting data packets to said peer device is carried out via said access point when said switching of said data collection device and said switching of said peer device is not synchronized.

Abstract
There is described a data collection device that can incorporate an encoded information reading unit that can operate within a system including an access point that is wireline connected to a server. The encoded information reading unit can include 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 can be 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 which further enables the device to transmit data received from a peer device to the system access point.

5. A data collection device for incorporation in a data collection system having an access point and a peer device, said access point adapted for wireline connection to a wireline bus, said data collection device comprising:
-
an encoded information reader unit selected from the group consisting of a bar code decode unit, an RFID reader unit, and a credit/debit card reader unit; a first radio transceiver for wireless transmission of data packets in an ad-hoc mode; a second radio transceiver for wireless transmission of data packets in an infrastructure mode; and a housing, wherein said encoded information reader unit is supported within said housing, wherein said housing is one of a hand held housing and a re-mountable housing; wherein said data collection device is operative to receive data packets from said peer device by said first radio transceiver for routing payload data of said data packets to said access point by said second radio transceiver and wherein said data collection device is further operative to receive data packets from said access point by said second radio transceiver for routing payload data of said data packets to said peer device by said first radio transceiver. - View Dependent Claims (6, 7, 8)
