Second Way: The other way to overcome the Repeater Count Limitations is

to divide the network into more than one segment. In this way the limitation

is less severe since the limitation is per segment. The segmentation is done

by using the RADring extension modules which act as a bridge and by that

dividing the network into two segments.

By using the extension modules the network efficiency get higher since the

bandwidth grows.
