A designer asked us this question and we thought it would be a good idea to share with the forum community:
As an Inclusive dealer who will have a RadioRa 2 system with over 100 devices, we would recommend dividing the device count evenly between Main Repeaters rather than having the maximum number of devices on one Main Repeater and just a few on the others.
For example, a system laid out as:
MR1 - 70 Devices
MR2 - 70 Devices
May transfer faster and maintain better communication than a system laid out as:
MR1 - 100 Devices
MR2 - 30 Devices.
Both configurations will work correctly and should not have issues. But for best practices we would always recommend a slightly more even balance between Repeaters if possible.
