- Internet through fiber cables
- Cable television (TV)
How It Works
Information travels through copper wires or fiber-optic cables from one place to another.
Advantages
- Strong and stable connection
- High speed (especially fiber internet)
- Less affected by weather
Disadvantages

- Difficult in remote areas
- Expensive to install
2. Wireless Telecommunication
Wireless telecommunication sends information without using wires.
It uses radio waves.
Examples
- Mobile phones
- WiFi
- Bluetooth
- Radio
- Television broadcasting
How It Works
Signals travel through the air using towers or routers.
Advantages

Most people today use wireless telecommunication every day.
3. Satellite
Satellite telecommunication uses satellites in space to send and receive information.
Examples
- Satellite TV
- GPS
- International phone calls
- Internet in remote areas
How It Works
- Signals are sent from Earth to a satellite
- The satellite sends them back to another place on Earth
Advantages
- Covers large areas
- Works in mountains, oceans, and villages
- Useful during disasters
Disadvantages
- Expensive
- Slight delay in communication
- Needs clear weather
