1.7.2 Configuring a Dual Cell system
A Dual Cell system is a coordinated, synchronized system of two base stations to cover a slightly larger radio area.
With the Enreach DECT 600 S, only 2 base stations can be set up in a chain.
Before installing a Dual Cell system, check the requirements regarding radio coverage, number of DECT users and their movement behavior, and installation locations of the base stations (building information). Verify if any interference factors are present that may have a negative impact on the DECT installation. For larger areas of use, we usually recommend the DECT 600 L system.
To configure a Dual Cell system, proceed in the following order:
*Set up the first base station (step (1) to (9))
*Add a server (step (10) to (17))
*Add at least one user (step (18))
*Set the first base station to Dual Cell(step (19))
*Add a second base station (usually done automatically)
