Wireless communication is the transfer of information over a distance without the use of electrical conductors or
"wires". The distances involved may be short (a few meters as in television remote control) or very long (thousands
or even millions of kilometers for radio communications) The forms of energy used for the transmission can be
radio frequency (RF), infrared light, laser light, visible light, or acoustic energy.
David E. Hughes induced electromagnetic waves in a signaling system; he transmitted Morse code by an induction
apparatus. In 1878, Hughes's induction transmission method utilized a "clockwork transmitter" to transmit signals.
In 1885, T. A. Edison used a vibrator magnet for induction transmission. In 1888, Edison deploys a system of
signaling on the Lehigh Valley Railroad.
Light, colors, AM and FM radio, and electronic devices make use of the electromagnetic spectrum. Wireless
communication spans the spectrum from 9 kHz to 300 GHz. [Wikipedia]

Intel planning to harvest free energy 07 Dec
2008
We're sitting in a room that's awash with
energy. There's photons of light hitting the
desk, thermal energy from body heat and
you could even harvest the energy from a
moving trackball on a BlackBerry.
Intel's chief technology officer Justin Rattner
has been detailing the latest research from
Intel labs into power saving and generation.
Chief among the systems being developed
are "wireless identification and sensing
platform," or WISPs. These small sensors
can be implanted into buildings, devices or
even humans and could generate power by
scavenging it from the environment, micro
generating their own power through sunlight,
thermal energy or even sound waves. [1]

'White Space' to Be Opened to Devices Connected to Web
November 5, 2008 The Federal Communications Commission
approved a plan that would allow those airwaves, called white
spaces, to be used by gadgets such as cellphones and laptops
connected to the Internet once that spectrum becomes available
after the national transition from analog to digital television in
February. [2]

WiFi Gains Strength in Cities November 5, 2008 Over the past three
years, large cities and rural towns promised to bring WiFi to every
street corner, park bench and doorstep. The wireless service was
to be the key to extending cheap Internet access to underserved
areas and low-income neighborhoods. [3]

Wireless turns iPod into a phone 6 December 2008 A freeware
application for the iPod Touch can turn the music player into a
virtual mobile phone. The software is a spin-off from technology
Truphone developed for smartphones and iPhones. Truphone uses
wi-fi technology in an iPod Touch to allow users to make calls to
other iPod Touch owners and Google Talk's messaging service
users. [4]
