The aim of the thesis is the design and implementation of a twisted-pair cable tester, capable of sending results to a mobile phone. Twisted-pair cables exist in almost every wired computer network built over the last 25 years. This type of testers is widely used by computer network engineers and technicians, when installing a new network structured cabling or troubleshooting existing networks. The first four chapters are referred to the basic concepts of computer networks, different types and protocols of networks and the devices used in them. In the fifth chapter there is a historical review of the technological evolution of networks and wiring until the establishment of the Ethernet standard and the use of twisted pair cables through structured cabling. The various types of twisted pair cables used in the Ethernet standard and how they work are then analyzed, while the sixth chapter analyzes the categories of control devices for such cables. Last chapters analyze circuit and board design, circuit and mobile application programming, and how electronic materials are selected. Finally, there is a chapter with suggestions for improving the device that was built.
