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
