Wireless
Introduction
Wireless technology refers to the transmission of data between two or more points that are physically not connected. Distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking.
History
The term 'wireless' came into public use to refer to a radio receiver or transceiver (a device that both sends and receives radio signals). The term is also used in the telecommunications industry to refer to telecommunications systems (e.g., radio transmitters and receivers, remote controls, computer networks, network terminals, etc.) which use some form of energy (e.g. radio frequency (RF), infrared light, laser light, visible light, acoustic energy, etc.) to transfer information without the use of wires.
Wireless Communication
Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires". The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). When the context is clear, the term is often shortened to "wireless". It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, PDAs (personal digital assistants), and wireless networking.
Wireless Networks
A wireless network is a computer network that uses wireless data connections between network nodes. Wireless networking is a method by which homes, telecommunications networks, and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless networks are generally implemented and administered using a transmission system called radio waves. This implementation takes place at the physical level (layer) of the network structure.
Wireless Devices
Wireless devices encompass a broad range of items that include, but are not limited to, smartphones, tablets, laptops, wireless headphones, smart watches, and other wearable technology. All of these devices are capable of interacting with networks and other devices wirelessly, providing users with a range of services and functionalities.
Wireless Standards
Wireless technology defines the electronic standards that allow devices to communicate without physical connections. Wireless technologies have widely spread lately in all areas of life including business, education, healthcare, and entertainment. Standards like Bluetooth, Wi-Fi, and 5G dictate how wireless devices communicate, and the nature of their interactions with one another.
Conclusion
Wireless technology has revolutionized the way we communicate and share information. With the advent of wireless devices, we are able to communicate across vast distances without the need for physical connections. As technology continues to advance, we can expect to see even more innovative uses for wireless technology in the future.
