Wireless technology & amazing facts

Wireless technology is one important factor in our day to day life right ? But how many of you know the important facts of wireless communication. So, here we discuss those things. Wireless communication is the transfer of data between two or more sites that do not use an electric conductor device as a medium for the transfer. Radio waves are used by the most prevalent radio technology. With radio waves, the range meant for Bluetooth may be short, for instance several metres or millions of kilometres for deep-space radio. It includes several different kinds of fixed, mobile and mobile applications, among them bidirectional radios, cell phones, PDAs and wireless networking. 

Examples of wireless applications include GPS units, garage door opener, mouse, keys and headsets and headphones, radio receivers, satellite TV, television transmission and cable. Either other electromagnetic wireless technologies, such as lighting, the magnetic fields or the use of sound, are a bit less widespread wireless communications ways.  In the history of communication, the term wireless has been used two times and has a slightly different meaning.

It was used for the first radio transmitting and receiving technologies from around 1890 and also for wireless telegraphy until around 1920 the new name radio was changed. In the 1960s, non-portable radios in the UK were continuous to be known as wireless sets. In the 1980s and 1990s, the word was reintroduced principally in order to differentiate digital devices that interact without cables from those that require wired or cables, such as those mentioned in the preceding paragraph.  Due to the emergence of technologies like mobile broadband, Wi-Fi and Bluetooth, that became its main use in the 2000s.

Amazing facts about wireless technologies

  • Prior to adopting the more consumer friendly term for Wi-Fi, previous names for Wi-Fi were Wave LAN, FlancSpeed, DragonFly, WECA and IEEE 802.11b direct sequenze.
  • The term “WiFi” is developed by Interbrand as a play on word “Hi-Fi” or “High Fidelity.”
  • Actually, Wi-Fi means nothing. Actually. Although Interbrand has developed the phrase, Wi-Fi is nothing. To the confusion the Wi-Fi Alliance was using an unsense “the standard for Wireless Fidelity” advertising tagline, which led many people to believe that Wi-Fi is a “Wireless Fidelity” abbreviation.
  • Up to 250 devices can be supported at once by most access points and wireless routers. In this case, the more connected devices the bandwidth allocation may change such that every device does not have a robust and dependable connection speed.
  • It might seem that we all dialled in yesterday yet wireless Internet was originally founded in September 1990!
  • In general, Wi-Fi signals emit by a classical router or are repeated in the form of a doughnut. A wireless coverage field in the form of a doughnut is created, and in the middle is a hole like a doughnut – where no coverage can be found. It’s a delicious thought now.
  • In the early 1970’s Bob Metcalfe designed Ethernet, the most used wireless network protocol, approximately half a century ago.
  • The average global internet speed is 5.6Mbps, but with an aperture of 28.6 Mbps, South Korea is ahead of the world’s fastest country !
  • Since June 2019, the internet is being used by 4.5 billion people – more than half the global population is connected as you are to the worldwide web.
