Study Notes
Wireless Communication
- Wireless communication is a type of communication that allows data to be transmitted from one device to another without the use of cables or wires.
Examples of Wireless Technologies
- Wi-Fi (Wireless Fidelity) for local area networks
- Bluetooth for personal area networks
- Cellular networks for mobile communication
- Satellite communication for global coverage
- Zigbee for low-power, low-data-rate applications
- Infrared (IR) for proximity-based communication
Intended Distances for Radio Wireless Communication
- Short-range: up to 10 meters (e.g., Bluetooth, Wi-Fi)
- Medium-range: up to 1 kilometer (e.g., wireless local area networks)
- Long-range: up to 10 kilometers (e.g., wireless metropolitan area networks)
- Global: limitless range (e.g., satellite communication)
Applications of Radio Wireless Technology
- Mobile phones and devices
- Wireless internet connectivity
- Radio broadcasting
- Emergency response systems
- Industrial control systems
- Navigation systems (e.g., GPS)
Less Common Methods of Achieving Wireless Communication
- Optic wireless communication using light signals
