This project was conducted by Real Wireless on behalf of Ofcom in order to determine the role which existing and additional spectrum, notably a potential 700 MHz band, might play in meeting growing demand for wireless broadband capacity over the next 10 to 20 years. The role of additional spectrum is considered against the background of a wide range of other capacity-enhancing techniques – including LTE-Advanced and small cells – which the wireless industry is developing and which are expected to emerge over the study period.
