RF (Radio Frequency) Module Operation

The cordless system uses a two-way Bluetooth® radio to transmit and receive data between the scanner and the base or Access Point. Designed for point-to- point and multipoint-to-single point applications, the radio operates using a license free ISM band, which sends relatively small data packets at a fast data rate over a radio signal with randomly changing frequencies, makes the cord- less system highly responsive to a wide variety of data collection applications and resistant to noisy RF environments. Bluetooth Class 2 power level provides a communication range of 33 feet (10m) between the scanner and base or Access Point, depending on the environment. See Flexible Power Management, page 3-15,for information about controlling this range.

System Conditions

The components of the cordless system interact in specific ways as you associate a scanner to a base or Access Point, as you move a scanner out of range, bring a scanner back in range, or swap scanners between two cordless sys- tems. The following information explains the cordless system operating condi- tions.

Linking Process

Once a scanner is placed into a cordless charge base, the scanner’s battery charge status is checked, and software automatically detects the scanner and links it to the base depending on the selected link mode.

Refer to Linking the Scanner to an Access Point, page 3-2,for information about linking to an Access Point.
