Wi Fi

Find a Hotspot

Wi-Fi networks use radio technologies called IEEE 802.11b or 802.11a
to provide secure, reliable, fast wireless connectivity.

A Wi-Fi network can be used to connect computers to each other, to
the Internet, and to wired networks (which use IEEE 802.3 or Ethernet).
Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands,
with an 11 Mbps (802.11b) or 54 Mbps (802.11a) data rate or with products
that contain both bands (dual band), so they can provide real-world performance
similar to the basic 10BaseT wired Ethernet networks used in many offices.

Who Can Use Wi-Fi?

Everyone can use Wi-Fi, almost everywhere in the world.
Home Wi-Fi networks can connect multiple computers to each other, to peripherals,
and to the Internet.
A Wi-Fi network can connect a family's computers together to share such hardware
and software resources as printers and the Internet.
That means everyone in the family can share stored files, photos and documents
and print them out on a single printer attached to one desktop computer—all without
unsightly cables running throughout the home.
In a home or home office, using Wi-Fi CERTIFIED equipment in your wireless network
gives you the ability to share a single high-speed broadband cable or DSL connection.
A Wi-Fi network can easily be expanded to ten users or more.
It also gives you assurance that the Wi-Fi CERTIFIED equipment you purchase today will
work with the equipment you add to your network in the future.
Wi-Fi networks also work well for small businesses, providing connectivity between
mobile salespeople, floor staff and behind-the-scenes finance and accounting departments.
Because small businesses are dynamic, the built-in flexibility of a Wi-Fi network makes it easy
and affordable for them to change and grow.
Using Enterprise-Level Wi-Fi Technology Large corporations and campuses use enterprise-level
technology and Wi-Fi CERTIFIED wireless products to extend standard wired Ethernet networks to
public areas like meeting rooms, training classrooms and large auditoriums.
Many corporations also provide wireless networks to their off-site and telecommuting workers
to use at home or in remote offices.
Large companies and campuses often use Wi-Fi to connect buildings.
Service providers and wireless ISPs are using Wi-Fi technology to distribute Internet connectivity
within individual homes and businesses as well as apartments and commercial complexes.
Wi-Fi Connects Travelers Wi-Fi networks are also found in busy public places like coffee shops, hotels,
airport lounges and other locations where large crowds gather.
This may be the fastest-growing segment of Wi-Fi service, as more and more travelers and mobile
professionals clamor for fast and secure Internet access wherever they are.
Soon, Wi-Fi networks will be found in urban areas providing coverage throughout the central city,
or even lining major highways, enabling travelers access anywhere they can pull over and stop.
Extending Your Current Network with a Wi-Fi LAN It's easy to add another wireless computer to a Wi-Fi network.
There's no need to purchase or lay more cable or find an available Ethernet port on your hub or router.
Just plug in your card or USB connection, turn on your computer and you're surfing the Net.
If your business grows and you need to move, you don't have to abandon your network infrastructure
investment or hire a networking company to rewire the new location.
And there's no network downtime—you can be up and running even before the furniture arrives.
Simply plug the system into a power outlet and you'll be operational in minutes.
