  • Optical scanner data collection network employing multi-packet transmission of decoded data
    Publication number: 20020125323
    Abstract: A data collection network featuring a plurality of cordless optical scanners communicating to a base terminal is disclosed. The cordless optical scanners are used for reading 2D optically encoded symbols. The optical scanner converts the 2D optically encoded symbol into decoded data. The optical scanner has a packet assembly component that converts the decoded data into packets. A communications component transmits the packets to the base terminal. The decoded data is packetized to accommodate 2D data codes such as PDF417, microPDF, Code One, DataMatrix, MaxiCode, or other 2D symbols. All of these symbols have maximum data capacities exceeding 1,000 bytes of information per symbol. Thus, the data collection network of the present invention provides users with the data transmission capacity required to use high-density data optical bar code symbols in an untethered working environment.
