Preparing the HBS
Figure 8-2: 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 guar-
antees 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:
