Different types of wi-fi connections


Connection: Wireless

Type of connection: Audio and video transfer

Definition: An open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions)

Example of its use: Between phones

Advantages: It only needs a very small amount of radio power to work ( <1/1000W) which is good for battery-operated devices such as mobiles, there's no other interference from other devices transferring data via Bluetooth, it's automatic and wireless and used widely

Disadvantages: Battery usage, it only has a range of 15 to 30 feet, easy to hack, data transfer rate is poor

Typical data transfer rates: 24 Mbits/s


Connection: Wireless

Type of connection: Audio and video transfer

Definition: IrrDA (Infrared Data Association)

Example of its use: Laptops, phones

Advantages: Low costs, no special hardware required, few international constraints, not as likely to have interference as much as other devices

Disadvantages: Very short range (less than 5 metres)

Typical data transfer rates: 4MB per second


Connection: Wireless

Type of connection: Any files (audio/video/media etc)

Definition: Using radio, microwaves, etc. (as opposed to wires) to transmit signal

Example of its use:

Advantages: Doesn't need any hardware

Disadvantages: May experience interference

Typical data transfer rates:
