Scientists are urging governments worldwide to turn old TV frequencies into free "Super Wi-Fi."

Instead of selling off old television frequencies to whomever pays more, the bandwidth of these frequencies can be transformed into free super-frequency Wi-Fi. Scientists say doing this will also boost economies, as well.

Thanks to a switch from analogue to digital transmissions, old television frequencies are becoming available for other uses around the world.

Currently, mobile phone networks are the highest bidders for these old frequencies.

Scientists from the Karlsruhe Institute of Technology (KIT) in Germany said that instead of selling them, a free-to-use, wide ranging Wi-Fi can be developed from them.

They've nicknamed the Wi-Fi from these frequencies "Super WiFi." This technology would have a far wider range than existing Wi-Fi networks, which are mostly transmitted over wireless local area networks (WLAN) at frequencies of 2 GHz or above.

If the old frequencies are used, Wi-Fi could be transmitted at lower frequencies, which results in a wider area covered. The coverage of the Super Wi-Fi could even be as big as several kilometers in radius.

This marks a great improvement from the current status of Wi-Fi.

The implementation of Super Wi-Fi would do away with expensive mobile services such as 4G, while leading to increased mobile internet usage and a wealth of economic benefits.

"Individuals, institutions and companies would be far less dependent on expensive mobile communications networks in conducting their digital communication. This would also be of great economic benefit," said Arnd Weber of the Institute for Technology Assessment and Systems Analysis (ITAS).

For disaster scenarios, people will have easy access to updates and communication.

The benefits are numerous. The challenge, however, is convincing governments it's the right thing to do.

People have argued these frequencies are common properties and should be made available to the public free of charge.
