WiFi- the wireless Ethernet 802.11b standard referring to the technology surrounding the radio transmission of the internet protocol data from an internet connection wirelessly to a host computer. This internet connection is usually at a higher speed than a connection such as a satellite, DSL, cable, or dial-up. Wireless Fidelity refers to an over-the-air connection between a wireless client and a home base between two wireless clients.
How does WiFi operate?
-WiFi operates in unlicensed frequency bands which makes it easy for anyone to set up a WiFi network connection. The connection covers an area of typically 100-500 feet, providing high-speed wireless access to a LAN and thus, the internet. Wifi components are on a fast-pace cost reduction curve as demand and volume increase due to the fact that the technology has become an industry standard.
How can you connect to WiFi?
-Today, most computers and laptops come equip with wireless transmitters. If your laptop doesn’t, you can buy a wireless adapter that plugs into the USB port of your computer. Once you’ve installed a wireless adapter, your computer will be able to automatically discover existing networks.
How can I set up a WiFi connection network?
-If you have numerous computers networked within your home, you can set up a wireless network with a wireless access point. If you have several computers that are not networked, or if you wish to replace your Ethernet connection, you’ll need a wireless router. This device contains a port to connect to your cable or DSL modem, a router, an Ethernet hub, a firewall, and a wireless access point.
What’s the future of WiFi?
-The future of WiFi is in the hands of a new microwave communication technology called WiMAX. Using this technology, we will be able to get online anyplace we can get cell phone service, including the road. WiMAX bases its operations on licensed bandwith, meaning the government will allow telecom carriers (who purchase at auction) to use it exclusively without interference from other devices or services. A WiMAX signal should reach several miles; or about the equivalent range of a cell phone tower signal. If properly used, WiMAX will amount to a national standard and can be expected to be faster than cell phone digital service, but slower than WiFi. Expect WiMAX to be common in major American cities within two to five years.
