Consulting Services for data centers & technical building infrastructures

Expert consulting and planning services

Joint consulting and careful planning form the basis for every project. For 15 years, we have been planning IT infrastructures and assisting in their construction and operation. The scope and progress of the planning phase can differ greatly depending on the starting situation and environment.

  • Does the project involve the extension of an existing or development of a new cabling infrastructure?
  • How much flexibility is there?
  • What additional capacities have to be provided to cater for future data rates?
  • Are there any special circumstances?

The result is a requirements profile for a bespoke cabling infrastructure that can dovetail appropriately with your IT strategy.

Development of revitalization concepts

Development of revitalization concepts

We analyse existing building infrastructures and develop revitalization concepts. Networks in older buildings are often based on old transmission standards that are no longer adequate for modern office communications. Keyword: Cable Sharing. Formerly, it was common practice to use unused cores in a network cable for a second network connection. Nowadays, higher bandwidths are needed at each workstation.
