As a result of the rapid spread of IoT and other radio equipment, there is a growing need for stable coverage within households, which, however, can not interfere with the proper functioning of any service.

The spread of UHF band (Ultra High Frequency) and higher frequencies in urban environments is often unpredictable, due to the complex urban structures and the effects of continuous change in the environment (public transport). Solving this problem is especially important, because of the bigger demand of stable coverage in case of big cities. This unpredictability makes it very difficult to ensure wireless data transmission across all parts of the home.

To solve the problem outlined above, it is possible to use a low-power, local-coverage transmitter. My thesis mission is to design and build such a transmitter unit using double-sideband amplitude modulation, which is capable of providing wireless data transmission within the home without disturbing other services, in a given frequency band.
