TNC has long-standing experience in the areas of
Mobile and fixed network design and optimization
Automated cell planning and configuration
Decision support and network provisioning tools
Radio wave propagation prediction
Capacity and power control for CDMA
Our methodologies include the fields of
Methods from stochastic modeling and our recent developments in
large scale combinatorial optimization led to the channel allocation
tool CHASS, presently used by the German network operator D2 Vodafone.
Mixed integer linear programming and heuristics such as Simulated
Annealing are deployed in our approach to fixed network optimization.
Previous versions of the corresponding tool have been successfully
tested by Nortel Dasa with cost reductions of more than 10% over existing
Combinatorial optimization and heuristics for hard problems provided the
key instruments to the development of decision support and network
Cryptology was the key issue in our design of digitized postage marks
and PC-franking, a joint project with Deutsche Post AG. Basic issues
were the electronic stamp and money transport.
