What is it about WI-FI

Wi-Fi Logo

A logo from the Wi-Fi Alliance that certifies network devices comply with the IEEE 802.11 wireless Ethernet standards. In the early 2000s, Wi-Fi/802.11 became widely used (initially 802.11b, then 802.11g), and within a short time, all laptops and other handheld devices came with Wi-Fi built in. Earlier laptops can be Wi-Fi enabled by plugging in a Wi-Fi adapter via the USB port or PC Card. For details about how Wi-Fi fits into a home or office network, see wireless LAN.

What's in a Name?

Wi-Fi sounds a lot like "hi-fi," thus it is mistaken to stand for "wireless fidelity." Although the term may have been inspired by "high-fidelity," Wi-Fi is officially just a catchy name, not "wireless fidelity."

A hotspot is a venue that offers Wi-Fi access. The public can use a laptop, Wi-Fi phone, or other suitable portable device to access the Internet. Of the estimated 150 million laptops, 14 million PDAs, and other emerging Wi-Fi devices sold per year for the last few years, most include the Wi-Fi feature.

For venues that have broadband service, offering wireless access is as simple as purchasing one AP and connecting the AP with the gateway box.

Hotspots are often found at restaurants, train stations, airports, libraries, coffee shops, bookstores, fuel stations, department stores, supermarkets and other public places. Many universities and schools have wireless networks in their campus.
