Wireless communication, or simply simply wireless, is the transfer of information or energy between two or more points that are not connected by an electric conductor. The most common wireless technologies use radio waves. With radio waves the distances can be short, such as a few meters for television [clarification needed] or even thousands or even millions of kilometers for deep space radio communications. It covers various types of fixed, mobile and portable applications, including bi-directional radios, cell phones, personal digital assistants (PDAs) and wireless networks. Other examples of wireless radio technology applications include GPS units, garage door openers, wireless mice, keyboards and headphones, headphones, radio receivers, satellite television, television and cordless phones.
Some less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic or electric fields or the use of sound. The term wireless has been used twice in the history of communications, with a slightly different meaning. It was initially used since 1890 for the first radio transmission and reception technology, as in wireless telegraphy, until the new word radio replaced it by 1920. The term was revived in the 1980s and 1990s primarily to distinguish digital devices that are Communicate wirelessly, such as the examples listed in the previous paragraph, those requiring cables or cables. This became its main use in the 2000s, due to the arrival of technologies such as LTE, LTE-Advanced, Wi-Fi and Bluetooth.
Wireless operations allow services, such as long-range communications, that are impossible or impossible to implement with the use of cables. The term is commonly used in the telecommunications industry to refer to telecommunication systems (eg radio transmitters and receivers, remote controls, etc.) that use some form of energy (eg, radio waves, acoustic energy) To transfer information without the use of cables. The information is transferred in this way over short and long distances.
Wireless communication is one of the greatest contributions of technology to mankind. Wireless communication involves the transmission of information at a distance without the help of cables, cables or any other form of electrical conductors. The transmitted distance can be within a few meters (for example, the remote control of a television) and thousands of kilometers (for example, radio communication).
Some of the devices used for wireless communication are cordless phones, mobile phones, GPS units, wireless equipment parts and satellite television.
Wireless Communication Advantages
Wireless communication has the following advantages:
I. Communication has been improved to convey information quickly to consumers.
Ii. Working professionals can work and access the Internet anywhere and anytime without having to carry cables or cables wherever they go. This also helps to complete the job at any time and improves productivity.
Iii. Physicians, workers and other professionals working in remote areas may be in contact with medical centers through wireless communication.
Iv. Urgent situation can be alerted through wireless communication. The affected regions can receive help and support with the help of these alerts through wireless communication.
V. Wireless networks are cheaper to install and maintain.
Disadvantages
The growth of the wireless network has allowed us to use personal devices anywhere, anytime. This has helped humanity to improve in all walks of life, but this has led to many threats as well.
The wireless network has led to many security threats to humanity. It is very easy for hackers to catch the wireless signals that are spread in the air. It is very important to secure the wireless network so that the information can not be exploited by unauthorized users. This also increases the risk of losing information. Solid security protocols should be created to protect wireless signals such as WPA and WPA2. Another way to secure the wireless network is to have a wireless intrusion prevention system.
