You must be at home browsing facebook ,snapchat ,9gag and tones of other sites.But suddenly the net is down and all hell brakes loose.’What happened to the wi-fi?’ you must be thinking. The internet has become another means of survival on because most of us cant really live without it.the Wi-Fi standard commonly known as IEEE 802.11, celebrates its 25th anniversary in a world where many people take Wi-Fi access for granted while streaming high-definition video and checking in on social media through their smartphones and laptops. Today the Wi-fi celebrates its 25th anniversary.It has come quite a distance since it first originated from a working group meeting in September1990. If you’re reading this story over Wi-Fi, thank a department store designer.
It was retail remodeling that spurred NCR, a venerable cash-register company, to find out how it could use newly opened frequencies to link registers and mainframes without wires. Its customers wanted to stop drilling new holes in their marble floors for cabling every time they changed a store layout.
The Internet of Things is a little different from Internet access applications, because you’re not interested so much in high Internet throughput, but you’re interested in longer range and higher power efficiency.
It’s not just companies supporting us in going to the Wi-Fi standard, but also end consumers and the world in general accessing the Internet
The 802.11ad amendment deals with 60 gigahertz wireless operations. The technical challenges of building radios in 60 GHz are much more difficult than in the 2-4 GHz or 5 GHz ranges. Those products are going to be later to market; I expect they’ll be more prevalent in 2016, 2017 and beyond. 60 GHz will be another spectrum band that will be available for very low range applications such as those within a room; primarily docking applications and video applications.
Standards have gone from rates of 1 to 2 megabits per second—which at the time was very respectable—to 11 Mb/s, then 54 Mb/s, then hundreds of Mb/s and now into the gigabit range. 802.11 technology is global and it’s almost an expected infrastructure utility in many places. I think the generation growing up now and anyone who is 30 years or younger expects Wi-Fi to be there. Since their cell phone data plans are limited, they look for Wi-Fi and they value Wi-Fi.
As it reaches that milestone, 802.11 is branching out into new areas like long-range, low-power networks, better performance in crowded places and more precise location sensing.
