The laboratory has the infrastructure to produce solutions for smart home systems, smart industrial and automation applications, and renewable energy applications. Examples of the various applications covered by the Smart Grids Laboratory include:

• Smart Home Automation,

Through this laboratory, researchers are able to develop smart systems by combining home appliances, smart meters and large-scale systems with internet-based systems, other software and databases. At this point, using intelligent analysis systems for power systems, researchers can experimentally implement solutions such as:

• Efficient use of energy resources for generation and consumption

and similar solutions.

In the Antennas and Propagation Laboratory, performance tests can be carried out on transmitting and receiving antennas and devices used both indoors and outdoors. Passive intermodulation tests, a capability that is in short supply in our country's industry, can also be conducted in this laboratory. This work attracts considerable interest from telecommunications companies. In addition to passive intermodulation tests, VSWR and isolation tests are also performed in the laboratory. By improving the performance of antennas, the fundamental building block of communication technologies, the aim is to provide uninterrupted and high-speed data transfer. As operators choose antennas that pass the tests with high scores, the goal is to deliver faster mobile internet and uninterrupted calls. The performance of transmitting antennas, which form the basis of the high-speed mobile data transfer systems currently provided by 3G and 4.5G technologies and whose capacity will be increased in the near future with 5G technology, is of great importance. Transmitters must deliver data at the highest possible speed, be affected as little as possible by environmental conditions and cause the least possible harm to human health. To this end, a test environment shielded from external signals has been created in the laboratory, where all kinds of signal-emitting devices are tested. For example, the Antenna Test Chamber creates an isolated area in which antenna tests can be carried out. It blocks incoming electromagnetic signals, preventing the equipment under test from being affected by them. At the same time, it prevents the strong electromagnetic waves generated during testing from escaping the test environment.

The Barkat Building Production Workshop became operational in February 2025 within the scope of a design and construction project. Work on prototype production and on resolving structural problems within the scope of the project is ongoing. In addition, the workshop focuses in particular on a TÜBİTAK project on timber structures, on scientific research projects and on other R&D activities.

In the workshop, course materials are developed and presented to students in order to reinforce topics that are difficult to grasp in traditional construction techniques and building technology courses offered to the architecture and interior architecture departments. At the same time, workshops, competitions and courses are organized within the context of these courses on the construction, loading and testing stages of structures such as timber houses, timber bridges, timber pergolas (canopies) and brick arches/vaults.
