6.2.2 Flexible Simulcast Function
Dali is also developing Flexible Simulcast functionality – capability to feed signal(s) from any BTS Sector to any
t43™
in an overall network, and vice versa. This feature is helpful for applications where dependent on time-of-
day the subscribers move from one area to another, and the available BTS capacity can “follow” them.
This functionality is achieved by interconnecting (daisy-chain)
tHost™
s dedicated to the BTS Sectors (Figure 6-4
–
tHost™
1, 2 and 3) using fiber optic interface, which allows signal exchange between
tHost™
s.
Similar to process during each
tHost™
simulcast, signals from each Sector
tHost™
are broadcasted to other
tHost™
s and
t43™
s in associated sub-networks. Framer/Deframer inside each
tHost™
acts as digital switching
matrix and directs desired carriers to the
t43™
sub-networks (
tHost™
1 sub-network is
t43™-
11 to
t43™
-15;
tHost™
2 sub-network is
t43™
-21 to
t43™
-24, etc.).
The Flexible Simulcast feature combined with the carrier/slot Traffic Statistic function will enable automated, on-
demand reallocation of the BTS resources, leading to timely and seamless network optimization.
It is worth mentioning that amount of carriers that can be simulcast between the sectors depends on number, type
and bandwidth of the carriers, and is ultimately limited by the maximum data rate supported by the optical links
(currently up to 6.144 Gbps).
