3.8.10 Multi-Hop
Sector Controllers can act as the root of a tree-like, Multi-Hop sector. In a Multi-Hop sector, subscribers are able to
relay data directly to/from other subscribers that are below them in the hierarchy. Radios lower in the hierarchy (i.e.
further away from the SC) are referred to as “children”, while those higher in the hierarchy are referred to as
“parents”. Subscribers continuously check for the presence of potential parents and select the one that should
provide the best throughput. Refer to Paragraph 3.8.4.3.
Throughput decreases when data travels through multiple hops since the data needs to be transmitted multiple times
in order to get to the end destination. See Figure 3-12. Latency increases when data travels through multiple hops
since each relay station needs to store and forward the data. See Figure 3-13.
