The 5G-RANGE project aims to provide broadband internet access to remote and rural areas using unused TV white space spectrum in an economically viable way. The project involves developing a new 5G access network architecture that uses cooperative spectrum sensing to identify unused TV channels and allows 5G signals from a base station to opportunistically transmit in the vacant channels. The project has 10 partners and will run for 30 months, developing a proof-of-concept using software-defined radios to demonstrate the new cognitive MAC layer and dynamic spectrum access capabilities.

Reproduction from [1].
Huge social impacts:
 3.9 billion people are unconnected around the world [1].
 Improve quality of life though information and education.

4. Providing broadband Internet in remote and rural areas in an economically viable way.
Solution:
• Using an efficient waveform for spectrum sharing
• Using unlicensed spectrum access (TV White Space – TVWS)
Economic Impacts:
• Market increase for operators.
• Broadband Internet in Remote Areas.
• Increased productivity on smart farms.
