kaapelilähetykset

Kaapelilähetykset refers to the transmission of television and radio signals through coaxial cables. This method of signal distribution was widely used in the past, especially for cable television networks. Unlike terrestrial broadcasting which relies on radio waves, cable transmission uses physical cables to deliver signals directly to homes. This often allowed for a greater number of channels and a more stable signal compared to over-the-air broadcasts, particularly in areas with poor reception.

The infrastructure for kaapelilähetykset typically involves a central headend that receives signals from various sources, processes them, and then distributes them through a network of cables to subscribers. These cables are usually laid underground or strung on poles. In its heyday, cable television offered a significant expansion of viewing options beyond the limited number of channels available through traditional antennas. Many older cable systems still operate on coaxial cable technology, though newer developments often incorporate fiber optics for higher bandwidth and faster internet services alongside television. The term is less common now as broadcast methods have evolved.
