  Using theoretical results presented in former papers, two prototypes were
developed, aiming at estimating within minutes the cost of a fibre network
deployment on a given territory. The first one helps defining the limit of an
urban territory and computes mathematical parameters representing its street
system. The second one gives global information on a fixed network deployment
on this territory, namely the probability distributions of distances and
attenuation from a node of the network to the final customer, and an evaluation
of the deployment cost, once given an architecture and engineering rules. This
allows a final user to easily design various network architectures in the tool,
to compare different deployment scenarios, and to optimize the budget and the
efficiency of the network in a few minutes. The results were compared on two
real French urban territories (in Tours and Rouen) to those given by an
optimization tool currently used by Orange.
