Which characteristic distinguishes community antenna systems from other types?

Community antenna systems (CATV) are primarily distinguished by their ability to broadcast local channels to subscribers. This system typically involves the use of a centralized antenna that collects over-the-air television signals, which are then distributed via coaxial cable or fiber optics to multiple households within a community. The emphasis on local channels allows residents to access essential regional programming, including news, weather, and community events, making it highly relevant for local audiences.

While options like internet access, direct streaming services, and mobile access capabilities are important features of modern telecommunications and media delivery systems, they do not specifically define community antenna systems. Instead, these features are more commonly associated with cable providers or internet service providers, which offer broader services beyond traditional broadcasting. The focus on broadcasting local channels is the fundamental characteristic that distinguishes community antenna systems, making it pertinent to recognize this feature in understanding their primary function.
