Wireless communication is the transmission of information or data between two or more devices without using physical connections such as cables or wires. Instead, it uses various types of electromagnetic waves, such as radio frequency (RF), infrared (IR), or microwave, to transmit data through the air.

Wireless communication has become increasingly popular over the years due to its convenience, flexibility, and the ability to connect devices over longer distances without the need for extensive cabling. Common examples of wireless communication technologies include:

Wi-Fi: Wi-Fi (Wireless Fidelity) allows devices like computers, smartphones, and tablets to connect to the internet or communicate with each other wirelessly within a local area network (LAN).

Bluetooth: Bluetooth technology enables short-range wireless communication between devices like headphones, keyboards, and speakers to exchange data over a personal area network (PAN).

Cellular networks: Cellular networks use radio frequencies to transmit voice and data to and from mobile devices, allowing users to make calls, send text messages, and access the internet on the go.

GPS: Global Positioning System (GPS) uses signals from satellites to determine the location of a device or user on Earth.

Wireless communication involves transfer of information without any physical connection between two or more points. Due to this characteristic, wireless communication has certain advantages. This would often include collapsing distance or space. Wireless communication has several advantages; the most important ones are discussed below Wired communication entails the use of connection wires. In wireless networks, communication does not require elaborate physical infrastructure or maintenance practices. Hence the cost is reduced. Wireless communication enables people to communicate regardless of their location. It is not necessary to be in an office or some telephone booth in order to pass and receive messages. Wireless communication devices like mobile phones are quite simple and therefore allow anyone to use them, wherever they may be. There is no need to physically connect anything in order to receive or pass messages. Improvements can also be seen in speed. The network connectivity or the accessibility were much improved in accuracy and speed. The wireless technology helps easy accessibility as the remote areas where ground lines can’t be properly laid, are being easily connected to the network.

Constant connectivity also ensures that people can respond to emergencies relatively quickly
