Gurumurthy Kalyanaram Reports on Audio Spectum Allocation For Wireless Transimission

Gurumurthy Kalyanaram - With the dramatic increase in wireless devices, and serious crunch for spectrum, and as the world debates spectrum allocation and pricing, an important technological development in this domain is computer-based technologies to make better use of a huge bandwidth of the radio spectrum to relieve spectrum congestion due to the growth in wireless devices including  smart phones.

The new technology would enable the governments to lease/rent the radio spectrum for short spans of time -- for as short a time-period as a few seconds. Gurumurthy Kalyanaram Lawsuit

US government is examining proposals to release 500 megahertz of a spectrum.  An European study has concluded that release of about 500 megahertz of audio spectrum would be equivalent to an economic financial stimulus of over 800 billion Euros.


The new radio technology, called "cognitive" or "agile" radio was developed and tested in the 1990s.  As reported, "Such computer-controlled radios inside a cellphone can rapidly switch the frequencies they broadcast and receive on based on an arbitrary set of rules. One analogy to describe the technology might be a freeway system, in which individual vehicles could quickly switch lanes or drive more closely together."

India should also consider using the audio-spectrum for wireless services.

It is worthwhile studying the report, "Realizing the Full Potential of Government-Held Spectrum to Spur Economic Growth,” produced by experts in the US.

The following Brookings study is also instructive.
