WiFi:
WiFi
is a term that is used to refer to wireless internet
signals. The history and derevision for it is
unknown. The technical term is: wireless networking
standard 80211. WiFi was designed for connecting
computers to the internet without using cords
or cables. And now it has better uses - like
digital radio!WiFi is similar to radio in that
it is a transmitted radio wave. The difference
is that WiFi uses a high frequency radio signal
(higher than AM or FM) to send and receive a digital signal.
Digital
WiFi signals do not have the hiss, pop, crackle,
or interference of AM and FM radio waves. It
is crystal clear all the time! That's why it's
so great for high quality stereo radio reception.
WiFi is designed to work within a 200-foot radius
of the antenna. The distance can be extended
using antennas and signal boosters.
WiFi
Radio Receivers
WiFi
radios are receivers that identify and decode
the digital WiFi internet signals and convert
them into radio programs. You may wonder how
it does that, and we explain it in our What Is
WiFi section, but believe me when I say that
these little radios can easily decode your favorite
radio programs and bring them to you in perfect
stereo clarity. I have found all of my favorite
shows being broadcast via WiFi. Whether from
the West or Mid-West, or here at WNJC and WFYL,
they are all equally clear with WiFi radio.
The
WiFi Signal
Ok,
if WiFi radio decodes a WiFi internet signal,
then you may be wondering how you get one near
your house. The location of a useable WiFi signal
is called a "HotSpot". HotSpots can come from
your own wireless connection for your computer,
or from a neighbor's wireless connection. The
density of WiFi signals in the US and Canada
is actually quite high in urban and suburban
areas. Many neighborhoods have so many wireless
networks that you will have to choose which HotSpot
to use. In addition, some communities provide
wide-spread public access to WiFi. While you
need the WiFi signal - you don't need a computer
to get reception. That's what a WiFi radio is
for! There are many excellent radios available. Click here to
