Conclusions LTE and LTE-Advanced quickly evolve to the global de-facto standard for Mobile Broadband. LTE and LTE-Advanced very successfully address Mobile Broadband capacity; still additional spectrum is required to meet the 1000x capacity challenge. LTE and LTE-Advanced well complement wire-line solutions to reach Digital Inclusion in rural areas. More efficient use of UHF spectrum by sharing and additional UHF spectrum in particular in the 700 MHz band help to reach the ambitious European Digital Agenda targets. Convergence of Broadcast and Mobile Broadband provides a vision on a more efficient common use of all available UHF spectrum with compelling technical benefits for Broadcast and Mobile Broadband. Nevertheless, challenges in business model and regulatory domain need to be addressed 16 Nokia Siemens Networks 2012
