Abstract

A wireless bar code symbol reading system for use in a work environment, comprising a wireless hand-supportable bar code symbol reader in two-way RF communication with a base station operably connected to a host system, by way of an RF-based wireless data communication link having a predetermined RF communication range over which two-way communication of data packets can occur in a reliable manner. When the wireless bar code symbol reader is located inside of the predetermined RF communication range based on measuring the strength of the detected reference signal, it automatically transmits to the base station, the symbol character data string produced while the reader is located inside of the predetermined RF communication range. When the wireless reader is located outside of the range, based on measuring the strength of said detected reference signal, the reader automatically collects and stores the symbol character data string produced during that time.
