It can perform
both traffic and RF analysis simultaneously as compared to many other
simulation tools that only perform one or the other. This has a distinct
advantage for rural WLL where the air interface is relatively important.
It is capable of simulating millions of calls per second, and recording
all of the system’s behavior.
The DECSim tool simulates every call, call duration, frequency, channel, timeslot, and every RF signal level in the entire network simultaneously. This means that any parameter anywhere in the system can be measured, stored, analyzed, and displayed. Thus complete performance and behavior can be studied for any single piece of equipment, any sub section of the network, or the entire network as a whole.
The simulation tool also has a powerful graphical interface that allows the display of all aspects of a networks performance based on geographical location. Several examples of network simulation are given below.

The
BBS Access mixed mode simulation tool, DECSim, is based on a full
blown random Monte-Carlo method and is therefore capable of simulating
almost any aspect related to the functionality of the DECLoop network in
real time. It has been specifically designed to fully replicate the
behavior of all the subsystem components as well as the entire network. It
is capable of simulating the behavior of several thousand subscriber units
and up to 100 base stations simultaneously. This is more than sufficient
for any scenario that is applicable to Thailand’s rural areas.
