Modes of Wireless Communication:

Wireless communications can be via:

•  Radio communication,
• Microwave communication, Example: long-range line-of-sight via highly directional antennas, or short-range communication,
• Light, visible and infrared (IR),Example: consumer IR devices such as remote controls or via Infrared Data Association (IrDA).
• Sonic, especially ultrasonic short range communication
• Electromagnetic induction short range communication and power

Applications may involve point-to-point communication, point-to-multipoint communication, broadcasting, cellular networks and other wireless networks.

•    Wi-Fi technology.                

WIRED DATA COMMUNICATION:
