Improve Performance with Honeywell’s Flexible Scanner Power Management

Posted May 2, 2016

If your business is experiencing network performance issues and you suspect that the Bluetooth scanner is interfering with other devices, you can turn down the power output of the Bluetooth scanner by simply scanning a barcode.  There are four barcodes you can scan in the Xenon/Granit/Voyager 1452/1602g User’s Guides:

  • Low Power (1%)
  • Medium Low Power (5%)
  • Medium Power (35%)
  • Full Power (100%).

A by-product when you turn down the power output is reduced range between the scanner and its base/access point/host.  I get asked a lot about the Bluetooth ranges at those power levels – scanner to base station.  So I tested several scanners (because I am a scan-nerd), and here is what I found.  Measurements are approximation – RF isn’t exact.  Also – I stopped at 100 feet because that’s how big my yard is…and because I’ve never seen an application that requires the Xenon to scan that far from the base station.

Bottom line is that if you are really concerned about RF interference, don’t be afraid to turn down the power on the Xenon & Granit.  They’ll still have plenty of range. That being said, in the vast majority of cases, the interference has nothing to do with the Bluetooth scanner.
