What is 802.11 wireless networking?
802.11 (sometimes called "Wi-Fi") is a set of protocols that are widely
used for small Local Area Networks. Another protocol called Bluetooth
allows devices to communicate wirelessly, but it is only useful for very
short ranges, and generally not used for home networking. Bluetooth
can be useful for networking personal devices in a small area, often
called a Personal Area Network (PAN).
802.11 actually encompasses several different protocols. The trailing
letters (i.e. the
g
in 802.11g) indicate different speeds and frequency
bands used.
What kind of wireless antenna range performance issues might affect my
wireless connection?
Radio waves don't really travel the same distance in all directions. Walls,
doors, elevator shafts, people, and other obstacles offer varying degrees
of attenuation, which cause the Radio Frequency (RF) radiation pattern
to be irregular and unpredictable. Attenuation is simply a reduction of
signal strength during transmission. Attenuation is registered in decibels
