Top 10 Applications of Wireless Technology

Wireless refers to the transmission of data or power between two or more points without the use of physical connections such as wires or cables. Instead, wireless communication typically relies on radio frequency (RF) signals, infrared (IR), Ultrasound or other electromagnetic waves to transmit information over distances.

Following are the features or characteristics of wireless signals in general:

• Wireless signals use EM waves to transmit data/voice without any physical connections.
• Wireless signals propagate through various mediums and their propagation depends on frequency and other environmental factors.
• Wireless signals use carrier frequency to modulate information so that it can be transmitted at longer distances.
• It encodes data to ensure reliable transmission and reception.

Following are the benefits or advantages of wireless technologies:

• Users can move freely within the coverage area while maintaining connectivity.
• Simplifies installation and setup as extensive cabling is not required.
• Reduces the cost of infrastructure and maintenance compared to wired systems.
• Easy to expand and adapt to changing system requirements. It is easy to upgrade in the future.
