Cable compensation
You must set cable compensation if the total cable length between antennas is greater than 500m/1640 feet.
About cable compensation
Cable length needs to be calculated when the distance in total cable length between antennas is greater than 500m/1640 feet. This is to prevent the DECT signals between antennas from becoming out of synchronization. If the antennas are not synchronized, beltpack handover will not happen effectively.
Setting cable compensation is particularly important if you have overlapping antenna coverage zones (RF cells) or the beltpacks need to move between coverage zones.
Example
Antenna 1: total cable length = 300m/984 feet.
Antenna 2: total cable length = 850m/2788 feet.
In this case, antenna cable length should be set.
