发明名称 Wireless code symbol reading system with automatic communication range dependent control
摘要 A wireless code symbol reading system including a wireless hand-supportable 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. The wireless hand-supportable code symbol reader is programmed to automatically detect when it is located inside and outside of the predetermined RF communication range. When the wireless reader is inside the RF communication range, then symbol character data is automatically transmitted to the base station, and when the wireless reader is located outside of the RF communication range, then symbol character data is automatically collected and stored in a data packet buffer, until the wireless reader has re-entered its RF communication range.
