Fraunhofer IPM supports Deutsche Telekom in optimized roll-out planning
BONN, 09-Oct-2018 — /EuropaWire/ — Deutsche Telekom is breaking new ground in its fiber-optic roll-out: It has become the first network operator in Europe to plan a pilot project using artificial intelligence. Thanks to faster and optimized route planning, the roll-out can cover more ground, faster. And customers will feel the benefits.
“The shortest route to the customer is not always the most economical. By using artificial intelligence in the planning phase we can speed up our fiber-optic roll-out. This enables us to offer our customers broadband lines faster and, above all, more efficiently,” says Walter Goldenits, head of Technology at Telekom Deutschland. It is often more economical to lay a few extra feet of cable. That is what the new software-based technology evaluates using digitally-collected environmental data. Where would cobblestones have to be dug up and laid again? Where is there a risk of damaging tree roots?
Pilot phase in Bornheim uses measuring vehicle
A measuring vehicle was sent out in Bornheim (near Bonn) this summer, equipped with 360° cameras and laser scanners as part of Deutsche Telekom’s FTTH (Fiber-to-the-home) project. It collected detailed environmental data using GPS technology. Depending on the terrain, the vehicle can cover 50 to 80 kilometres per day. All told, it collects approximately 5 GB of surface data per kilometer.
The effort and thus costs involved in laying cable depend on the existing structure. First, civil engineers open the ground and lay the conduits and fiber-optic cables. Then they have to restore the surface to its previous condition. Of course, the process takes longer with large paving stones than with dirt roads.
Fraunhofer IPM supports automated data evaluation
“Such huge amounts of data are both a blessing and a curse,” says Prof. Dr. Alexander Reiterer, who heads the project at the Fraunhofer IPM. “We need as many details as possible. At the same time, the whole endeavour is only efficient if you can avoid laboriously combing through the data to find the information you need. For the planning process to be efficient the evaluation of these enormous amounts of data must be automated.” Fraunhofer IPM has developed software that automatically recognizes, localizes and classifies relevant objects in the measurement data.
The neural network used for this recognizes a total of approximately 30 different categories through deep learning algorithms. This includes trees, street lights, asphalt and cobblestones. Right down to the smallest detail: Do the pavements feature large pavement slabs or small cobblestones? Are the trees deciduous or coniferous? The trees’ root structure also has a decisive impact on civil engineering decisions.
Once the data has been collected, a specially-trained artificial intelligence is used to make all vehicles and individuals unidentifiable. The automated preparation phase then follows in a number of stages. The existing infrastructure is assessed to determine the optimal route. A Deutsche Telekom planner then double-checks and approves it.
Deutsche Telekom’s broadband roll-out
Deutsche Telekom invests around five billion euros per year. Running to over 460,000 kilometers, the company operates the most extensive fiber optic network in Europe. Broadband build-out is at the top of the company’s agenda; in 2017, Deutsche Telekom installed some 40,000 kilometers of optical fiber. In 2018, this figure will increase to 60,000 kilometers, increasing Deutsche Telekom’s fiber-optic network to more than 500,000 kilometers.
The Fraunhofer Institute for Physical Measurement Techniques IPM develops customized measurement techniques and systems for industry. It specializes in optical measuring systems for mobile 3D acquisition of the geometry and position of objects. The institute designs and builds laser scanners, lighting units and camera systems for use on trains or vehicles. Evaluating measurement data efficiently is of ever greater importance. Given this, its work increasingly focuses on the development of data interpretation software. Fraunhofer IPM develops machine learning algorithms and implements them through the concept of deep learning.
