Preparing the HBS
Figure 11‐2: HBS Mobility Configuration
The maximum distance is a nominal common distance assumed by the HBS for all HMUs in its
sector. It is taken as the maximum distance any HSU can be from a HBS. (It effectively
guarantees an identical propagation delay for all HSUs in the sector to compensate for rapid
HSU movement.) If the distance is set too small, there is a risk of sync loss for distant HSUs; if
it is set too large it will reduce performance across the sector. The choice is part of RF
planning for Mobility projects and is beyond the scope of this manual.
We will pre‐register three HSU slots to levels A, B and C and time slots to each level as shown:
