Terrestrial Broadcast
Terrestrial broadcast is a method of transmitting television and radio signals over the air using ground-based transmitters and antennas, without relying on cables, satellites, or the internet. It enables the distribution of audio and video content to a wide geographic area, typically using frequencies in the VHF and UHF bands. This technology forms the backbone of traditional over-the-air broadcasting services, such as digital TV (DTV) and FM/AM radio.
Developers should learn about terrestrial broadcast when working on projects involving media distribution, broadcast engineering, or IoT applications that use similar transmission principles. It is essential for roles in broadcasting companies, telecommunications, or regulatory compliance, as it underpins public service media, emergency alert systems, and local broadcasting infrastructure. Understanding this technology is also valuable for developing hybrid systems that integrate broadcast with internet-based streaming.
