Disadvantages

z

Signals go through a large number of nodes, and therefore the line reliability is low.

z

Faults in upper-level BTSs may affect the normal operation of lower-level BTSs.

z

The number of chain levels cannot exceed three.

4.3 Tree Networking Mode

This section describes the application scenarios, advantages, and disadvantages of the tree networking mode.

Application Scenarios

The tree networking mode is applicable to areas where network structures, site distribution, and subscriber distribution are complicated, for example, areas where subscribers are widely distributed and hot spots gather.
