Bluetooth Peripherals
The Warrington is equipped with a Bluetooth radio, making it is possible to communicate
with a variety of Bluetooth peripherals, including GSM/GPRS handsets, scanners, printers,
and so on.
with a variety of Bluetooth peripherals, including GSM/GPRS handsets, scanners, printers,
and so on.
The range of the Bluetooth radio is limited to approximately 10 meters.
Psion Teklogix provides built-in support for the Bluetooth peripherals listed below.
•
GSM/GPRS universal handset.
•
Bluetooth printer.
•
Bluetooth headset.
Keep in mind that Bluetooth and IEEE 802.11b/g radios both operate in the 2.4GHz band.
Although the Warrington includes features to minimize interference, performance of the
system will not be optimal if you use both radios simultaneously. Typically, when both
radios operate in the hand-held at the same time, they cannot transmit simultaneously—this
has a negative impact on overall system throughput. To minimize the impact on the back-
bone 802.11g network, Psion Teklogix recommends using Bluetooth peripherals that have
low transaction rates (such as printers and scanners).
