6.2.2 Flexible Simulcast Function

Dali is also developing Flexible Simulcast functionality – capability to feed signal(s) from any Base Station Sector

to any DRU 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 Base Station capacity can “follow”

them.
This functionality is achieved by interconnecting (daisy-chain) DAUs dedicated to the Base Station Sectors

(Figure 6-4 – DAU1, 2 and 3) using fiber optic interface, which allows signal exchange between DAUs.
Similar to process during each DAU simulcast, signals from each Sector DAU are broadcasted to other DAU’s

and DRUs in associated sub-networks. Framer/Deframer inside each DAU acts as digital switching matrix and

directs desired carriers to the DRU sub-networks (DAU1 sub-network is DRU11 to DRU15; DAU2 sub-network is

DRU21 to DRU24, etc.).
The Flexible Simulcast feature combined with the carrier/slot Traffic Statistic function (GSM standard – see

Section 2.3.7.3.4) will enable automated, on-demand reallocation of the Base Station 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).
