In the past two years, Wi-Fi-devices Also known as 802.11b/g/n – has emerged as the dominant standard for wireless LANs – WLANS worldwide. Anyone can set up a Wi-Fi network and cover an area of typically 100-500 feet with Internet access. Wi-Fi has 100% global
It Has Become The TCP/IP Of Wireless
A single networking standard for all developers, equipment manufacturers, service providers and users. As with TCP/IP, any innovation in Wi-Fi benefits everyone else in the Wi-Fi community.
Hundreds of equipment manufacturers (OEMs) are now flooding the market with millions of Wi-Fi devices and access points (“APs” — wireless hubs).
The single Wi-Fi standard ensures these devices all interoperate with each other, so for example, an access point made by Netgear will communicate with a network card from Linksys.
A few years ago, APs (Access points) cost over $1,000
Now they are less than $100 today, and Wi-Fi cards that were once $700 now regularly sell for under $50 or are included free as part of a laptop, or other device. As prices have dropped, millions of private Wi-Fi networks have been deployed in offices and homes. Wi-Fi networks have also begun appearing in public hotspots.
The Cost Of Wi-Fi Components
Wi-Fi radio chips, which cost $100 in 2000, now cost only $8, and fierce competition among commodity radio manufacturers promises to push this price much lower in the coming years.
A future with widespread Wi-Fi networks in homes, offices and in public spaces will be filled with all kinds of Wi-Fi enabled devices. It took at least ten years for modems and wired Ethernet ports to become standard on laptops.
According to market research firm In-Stat, 5.7% of all notebooks were shipped with built-in Wi-Fi devices only a few years after Wi-Fi becoming a widely-adopted standard.
Companies Are Swarming To Wi-Fi Devices
Now cell phones have a low cost Wi-Fi radio to connect to Wi-Fi hot spots, taking traffic off of overloaded (and expensive) cellular networks, and sucking in broadband content like streaming video. Or switch over to a private Wi-Fi network in the enterprise or at home to do voice over IP.
The best silicon engineers in the world at Intel, Atheros, Broadcom, Intersil, Texas Instruments, and other , and these kinds of innovations will flood the market in the next five years. Motorola already plans to introduce a cell phone with integrated Wi-Fi by the end of 2003 and beyond.
Automobiles — New cars are already packed with data-hungry devices
Update your navigation system with the latest traffic data, download the day’s Wall Street Journal audio edition to listen to on the way to work. When you pull into your garage, your car will “now dock” with your home Wi-Fi network.
