A wireless network uses radio signals or microwaves to broadcast data and information. Rather than being transmitted through traditional coaxial, CAT5 ethernet or other standard wired methods, the data is beamed out over the airwaves.
Wireless networks offer advantages for some. Users with personal digital assistant (PDA) handhelds such as Palm Pilots, wifi enabled cell phones, or users with laptops can use wireless technology to allow them the convenience to move about while maintaining their network connectivity. Another pro is the ability for users to network desktop computers at various locations without having to deal with the hassle or expense of running a wired connection to that spot.
Most wired networks operate at 100mbps, and many organizations have upgraded to the newer standard of 1gbps.
A large percentage of wireless networks operate at 11mbps, roughly equivalent to the old wired speed of 10mbps. Most wireless network equipment available today is compatible with both 802.11b and the faster 802.11g which operates at speeds up to 54mbps. There is also a new, emerging wireless network standard, 802.11n, which theoretically increases both the speed and the range of the wireless network.
WHAT CAN AFFECT MY WI FI CONNECTION
Wireless network speeds are affected by obstructions such as walls and floors. Most wireless network equipment, for consumers in particular, also operates in the 2.4Ghz frequency range. This is the same range as other household devices such as cordless phones, baby monitors, etc. The interference from these devices, as well as microwave ovens and other electrical interference can greatly impact the range, speed and quality of your wireless network.
