Table 11 Number of portables (highly mobile users) per ELU31 board
with 16 channels
Table 12 Number of portables (highly mobile users) per ELU31 board,
(with 16 channels), per base station.
Note:
For highly mobile users the most important limitation to consider
is the one mentioned in chapter 4.4.5 Signaling/Roaming traffic
on page 38.
When one or two base station(s) is/are connected to the ELU31 board
the limitation is the number of available channels between a base station
and the ELU31 board. With 3 or more base stations connected to a board
with 16 b-channels the limitation will be the number of available channels
over the back plane. With 5 or more base stations connected to a board with
32 b-channels the limitation will be the number of available channels over
the back plane.
