Beyond the Obstacles: An Adaptive Relay Transceiver

Advances in wireless communication are propelling the development of microwave applications for smart cities, the Internet of Things, and 5G wireless communications. However, in practice, blockages, such as hands, bodies, and walls, severely limit microwave signal propagation. Thus, good-quality relay systems are highly valuable because they can significantly improve network coverage and system throughput. Relay systems can also save energy by switching operation mode according to the working environment. In this article, a relay transceiver is introduced that was awarded first place in the Adaptive Relay Transceiver Student Design Competition (SDC) during the IEEE Microwave Theory and Techniques Society (MTT-S). 2019 International Microwave Symposium (IMS2019). This competition category was sponsored by MTT-S Technical Coordinating Committee 20.
