Which system is likely to use a community antenna?

A community antenna system is commonly associated with cable television distribution. This system collects television signals from various sources and then transmits these signals through a single antenna. The intent is to serve multiple households or a community, allowing them to access a variety of channels without needing individual antennas for each residence. This centralized approach not only simplifies installation but also can improve signal quality for users within the system’s range.

While the other systems listed also involve data or signals distribution, they operate under different principles. For example, fiber optic networks use light to transmit data through thin fibers, creating a much faster and higher capacity communication method that doesn't rely on a community antenna structure. Wireless broadband utilizes radio signals for internet access and does not necessarily require a community antenna system, as it can delivers signals wirelessly to individual devices. Satellite communication transmits signals directly from satellites to receivers, negating the need for centralized antenna systems like those used in cable television distribution.
