ABSTRACT:
A wireless automatically-activated bar code symbol reading system for use in a work environment, the system including a device controller programmed to automatically detect when a wireless hand-supportable bar code symbol reader is located inside of a predetermined RF communication range based on measuring the strength of a detected reference signal, and thereupon to automatically transmit to a first RF-based transceiver, the symbol character data string produced while the wireless hand-supportable bar code symbol reader is located inside of the predetermined RF communication range. Also, the device controller is programmed to automatically detect when the wireless hand-supportable bar code symbol reader is located outside of the predetermined RF communication range based on measuring the strength of the detected reference signal, and thereupon to automatically collect and store in the data packet group buffer, the symbol character data string produced while the wireless hand-supportable bar code symbol reader is located outside of the predetermined RF communication range.
