Based on this, engineers in my company and others, many belonging to institutions such as the IEEE (Institute of Electrical and Electronics Engineers), have got together to develop a standardised technology that will work well with the spectrum identified - "white space spectrum" - and be optimal for machines.
There, Microsoft have invested in developing white space spectrum to bring an African audience into the Web and into device ownership.
FORBES: Who Will Win The Next Phase of Growth In Smartphones?
He notes that they recently freed up TV white space spectrum.
FORBES: CES: FCC Chair Julius Genachowski, Live From Las Vegas
Unleashing white spaces spectrum has the potential to exceed even the many billions of dollars in economic benefit from Wi-Fi, the last significant release of unlicensed spectrum, and drive private investment and job creation.
ENGADGET: FCC approves first white space device and database for Wilmington, NC
Researchers at Wake Forest University recently developed a new type of light bulb that uses field-induced polymer electroluminescent technology to create a soft white, full spectrum light that could last a decade.
And new innovations such as printed circuit technology and the white space radio spectrum (transmitting data over unused TV channel airwaves as we switch from analogue to digital TV) are all helping to create a world where everything can talk to everything else, and everything to us.
This could help to fill in the huge white spaces of unused spectrum.
The technology uses gaps in radio spectrum, called 'white spaces', which exist in between frequency bands.
ENGADGET: UK regulator wants white space wireless service in 2014, starts trials this fall
The FCC has been more than a little eager to repurpose spectrum as wireless internet access takes off: white spaces and iDEN frequencies have already switched roles, and that's not including the myriad of spectrum swaps.
In a little known battle in the UK, both Google and Microsoft are competing for white spaces, gaps in the radio spectrum between TV, radio and mobile.

On the other side of the spectrum were the women in white and ivory like Kerry Washington in a dress with a structured bodice from Rodarte, Naomi Watts in a lace and silk tulle frock from Marchesa and Sofia Vergara in a ruched and draped silk satin dress by Donna Karan.
They know that a wide spectrum of grey lies between the white of peace and the black of war.
White space devices offer a creative and efficient way to use spectrum that would otherwise lie fallow.
ENGADGET: UK regulator wants white space wireless service in 2014, starts trials this fall
So-called white spaces devices are currently being trialled for use in the spectrum gaps freed up by the digital TV switchover.
The pilot will test the inter-operation of white spaces devices, white space databases and the processes to mitigate against causing any undue interference to current spectrum users.

Mr Ball next treats us to a brisk description of the human eye (remember rods and cones from school biology?), an explanation of why Newton was right and Goethe wrong about the composite character of white light, and an account of the 19th-century regimentation of the continuous colour spectrum by means of colour wheels and other classifying devices.
