Telecommunication Systems - JSS3 Basic technology Past Questions and Answers - page 2

Telecommunication systems primarily facilitate the transmission of signals, enabling communication between individuals or devices over distances. They ensure efficient exchange of information through various technologies such as radio waves, satellites, and fibre optics, supporting both voice and data communication needs globally.

Mobile telecommunication systems use radio waves to connect mobile devices (such as phones and tablets) to cellular networks. These networks consist of base stations that communicate with devices within their coverage area, allowing users to make calls, send messages, and access data services while on the move.

Satellites in telecommunication systems act as relay stations in orbit around the Earth, facilitating communication over vast distances. They receive signals from ground stations, amplify them, and retransmit them back to different locations on Earth, enabling global coverage and supporting services like television broadcasting, internet connectivity, and international phone calls.

Fibre optic systems transmit data using light pulses through thin glass or plastic fibres. This technology offers higher bandwidth, faster data transmission rates, and greater reliability compared to traditional copper wires. Fibre optics are crucial for long-distance communication and form the backbone of internet infrastructure worldwide.

Mobile networks provide flexibility and mobility, allowing users to communicate while on the move. They have broader coverage compared to landlines, especially in remote or underserved areas. Mobile systems also support a wide range of services beyond voice calls, including mobile internet access, messaging, and multimedia applications.
