Performing Lane Tuning
Lane Tuning consists of selecting the frequencies to be used on the channels and setting the
attenuation for the channels to control the ERP of the reader. These are configured using the web
interface. It is recommended that Kapsch Operations Group perform lane tuning to properly configure a
site. If the integrator/operator wishes to perform the lane tuning, the following guidelines apply:
 The same FDM channel frequency should not be used on adjacent lanes (including straddle and
shoulder).
 The same TDM channel from 2 synchronized readers should not be used on adjacent lanes
(including straddle and shoulder).
