Wireless

• Aggregated Fast Transition
Aggregated FT improves on IEEE 802.11r, Over-the-DS fast roaming. In conjunction with Zebra wireless
LAN infrastructure, the device will achieve more reliable and consistent fast roaming. Default: enabled.
• Scan Assist
The device monitors neighbor access points and retrieves roaming related information from the Zebra
wireless LAN infrastructure without doing scans. Using this Scan Assist feature, the device improves
roaming. Default: enabled.
Bluetooth
Bluetooth devices can communicate without wires, using frequency-hopping spread spectrum (FHSS) radio
frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band (802.15.1).
Bluetooth wireless technology is specifically designed for short-range (10 m (32.8 ft)) communication and low
power consumption.
Devices with Bluetooth capabilities can exchange information (files, appointments, and tasks) with other Bluetooth
enabled devices such as printers, access points, and other mobile devices.
The device supports Bluetooth Low Energy. Bluetooth Low Energy is targeted at applications in the healthcare,
fitness, security, and home entertainment industries. It provides reduced power consumption and cost while
maintaining standard Bluetooth range.
Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used with
Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work.
There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and discoveries
during critical 802.11b communications. AFH for Bluetooth consists of four main sections:
• Channel Classification - A method of detecting an interference on a channel-by-channel basis, or
predefined channel mask.
• Link Management - Coordinates and distributes the AFH information to the rest of the Bluetooth network.
• Hop Sequence Modification - Avoids interference by selectively reducing the number of hopping channels.
• Channel Maintenance - A method for periodically re-evaluating the channels.
When AFH is enabled, the Bluetooth radio “hops around” (instead of through) the 802.11b high-rate channels. AFH
coexistence allows enterprise devices to operate in any infrastructure.
The Bluetooth radio in this device operates as a Class 2 device power class. The maximum output power is 2.5
mW and the expected range is 10 m (32.8 ft). A definition of ranges based on power class is difficult to obtain due
to power and device differences, and whether in open space or closed office space.
NOTE: It is not recommended to perform Bluetooth wireless technology inquiry when high rate 802.11b operation is
required.
