The capabilities and therefore the uses of Wi-Fi have developed significantly over the past 15-20 years. Prodec Networks has put together an Info-graphic to show the advancements from invention to present day and beyond…
Key wireless developments
Wi-Fi was invented in 1991 by NCR Corporation and was initially designed for cashier systems under the name WaveLAN with speeds of 1-2mbps. It wasn’t until 1999 that the Wi-Fi Alliance was formed as the trade association holding the Wi-Fi trademark. The term Wi-Fi was then later used commercially in 2000. With the first generation of Wi-Fi products having a maximum data rate of 11mbps and operating in the 2.4GHz band.
At this time, Wi-Fi was mainly used in businesses for email and web browsing. It wasn’t until mid to late 2000’s with the development of smart devices that Wi-Fi was being used for playing and downloading video, music and apps and also for social media. As a result Wi-Fi density became a big issue for many businesses as more and more devices tried to connect to the corporate network, which was unable to cope with user demands.
IDC Research reported that more devices were shipped without an Ethernet port than with one for the first time ever in 2011. As a result of the smart device boom, Wi-Fi security is now a key issue for many businesses. Older Wi-Fi networks are able to only detect rouge devices using Wireless Intrusion Detection Systems (WIDS) whereas Wireless Intrusion Prevention Systems (WIPS) give the ability to prevent these rouge devices entering the network using Wi-Fi before any damage can be done.
