wireless technology
Wireless communication is among technology’s biggest contributions to mankind. Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors. The transmitted distance can be anywhere between a few meters (for example, a television’s remote control) and thousands of kilometres (for example, radio communication).
The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even 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. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.
Somewhat 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 communications history, with slightly different meaning. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920. The term was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires, such as the examples listed in the previous paragraph, from those that require wires. This is its primary usage today.
Advantages
i. Communication has enhanced to convey the information quickly to the consumers.
ii. Working professionals can work and access Internet anywhere and anytime without carrying cables or wires wherever they go. This also helps to complete the work anywhere on time and improves the productivity.
iii. Doctors, workers and other professionals working in remote areas can be in touch with medical centres through wireless communication.
iv. Urgent situation can be alerted through wireless communication. The affected regions can be provided 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 wireless network has enabled us to use personal devices anywhere and anytime. This has helped mankind to improve in every field of life but this has led many threats as well.
Wireless network has led to many security threats to mankind. It is very easy for the hackers to grab the wireless signals that are spread in the air. It is very important to secure the wireless network so that the information cannot be exploited by the unauthorized users. This also increases the risk to lose information. Strong security protocols must be created to secure the wireless signals like WPA and WPA2. Another way to secure the wireless network
is to have wireless intrusion prevention system.

Wireless technology is growing very rapidly these days it has its advantages but it also has its disadvantages and you summarized it up. Very nice article. Great job.
ReplyDeleteIt is interesting to read about the advantages and the disadvantage of wireless technology and I think it is important to have a wireless technology but on the other hand it has many disadvantages.
ReplyDeleteYour articles shows many examples of wireless technology, but I would like to explain more about the PDA's it is any small mobile hand-held device that provides computing and information storage and retrieval capabilities for personal or business use, often for keeping schedule calendars and address book information handy.
it is a really fabulous article to read, you have posted a valuable information that every one need to know about using the internet and the technology used by the wireless, and you also mentioned the advantages and the disadvantage.
ReplyDeletewell done :)
Wireless technology is the future! we, as IT Professionals, should focus on learning more about it. Good job Rouda!
ReplyDeletegood job, so at the end.. which one is better to use, wire or wireless connection? given the information you gave us above.
