BTS Optimization for GSM networks
Automatic optimal cellsite selection and equipment configuration


Tool description:

BTS_Opt is a decision support tool that
selects optimal network configurations from a huge set of predefined
possible cell sites each with variable configurations like antenna main
direction, antenna downtilt, and optionally different EIRP for macro/micro
cell layout.

BTS_Opt optimizes covered traffic given
by different traffic distributions (e.g. day and nighttime traffic).

BTS_Opt is a selftailored
branchandbound optimization algorithm solving your problems to optimality.
It does not come with the drawbacks of oftenused heuristics. In many cases
the optimal solution is found at early stages of the algorithm and the
remaining time is just used to prove optimality in a mathematical sense.
Starting with a reasonable initial solution and improving it constantly,
BTS_Opt may be terminated at any time returning a feasible and improved
network configuration together with an upper bound to evaluate this
particular solution.

Test scenario:

An urban area of 8 square kilometers
with 1000 traffic nodes.

30 possible sites with 4 different
configurations each. The maximum number of erected BTS should be 10.

The number of possible network
configurations is 1.2e14. Evaluating every solution would be out of
reach.

BTS_Opt finds the optimal
configuration within 40 minutes by exploring just 0.00006 % of all
solutions and cutting the rest by bounds.

The optimal solution found covers 35 %
more traffic than a reasonable initial solution.

Features:

Various options facilitate self defined branching rules and search
strategies to get a grip on even toughest problems.

Additional constraints ensuring the compliance with governmental radiation
limits may optionally be used for environmentally compatible network
configurations. Otherwise, reconfiguring your network at later stages to
meet public demands may be very expensive.

Offers a the simple, easytouse graphical user interface and is perfectly
suited to be used as an AddOn in leading GIS and radio network planning
software tools.
Highlights:
Your benefits:

Get more revenue.
BTS_Opt maximizes the service quality of
your existing network. More traffic can be served and last but not least
billed.

Save millions in
operational costs. BTS_Opt figures out sites that are not
needed. The same amount of traffic might (even better) be served with less
but cleverly arranged sites.
