Wireless communication refers to the transfer of information between two or

more points without the use of physical wires or cables. Instead, it uses radio
waves, infrared, satellite, or microwave signals for data transmission.

Key Components:

1. Transmitter – Converts and sends data using electromagnetic waves.

2. Receiver – Captures the transmitted signal and converts it back to usable


data.

3. Antenna – Facilitates the transmission and reception of signals.

4. Medium – Free space or atmosphere where signals travel.

Types of Wireless Communication:

1. Radio Communication – Used in AM/FM radios, walkie-talkies.

2. Microwave Communication – Used in satellite and cellular networks.

3. Infrared Communication – Used in TV remotes, short-range


communication.

4. Bluetooth – Short-range communication between devices.

5. Wi-Fi – Wireless local area networking for internet access.

6. ZigBee – Used in home automation and IoT devices.

7. Satellite Communication – Long-distance global communication.

8. Mobile Communication – GSM, 3G, 4G, and 5G technologies for telephony


and data.

Advantages:

No cables required (mobility and flexibility).

Easier installation.

Supports remote communication.

Scalable and widely accessible.

Disadvantages:
Susceptible to interference.

Security concerns (data can be intercepted).

Limited bandwidth compared to wired.

Signal degradation due to obstacles.
