Increasing Location Accuracy
This appendix describes the impact that band steering can have on location accuracy. It also explains how RTLS can be
used to increase location accuracy.
Understand Band Steering's Impact on Location
Band steering can negatively impact location accuracy when testing in a highly mobile environment. The biggest
hurdles to overcome are scanning times in 5 GHz frequency.
