Doubling traffic each year over a decade leads
to a 1000x capacity challenge
Addressable by
• substantial performance improvements of the
technical solution
• massive amount of additional base stations,
primarily small cells near traffic hot spots
• massive amount of additional spectrum,
high bands like 2600 MHz and 3500 MHz well
suited for small cells
Challenges in the physical constraints of the radio
channel
Addressable by
• costly performance improvements of the
technical solution limited by return on invest
• additional base stations strictly limited by return

• additional spectrum at low frequencies,
e.g. at 700 MHz

not considering all possible but costly technology measures
700 MHz band for mobile broadband is a valuable step towards reaching DEA target data rates
Together with spectrum sharing, 30 and 50 Mbps targets get into reach

Convergence Potential of Terrestrial TV and Mobile Broadband
An Integrated UHF Multimedia Network based on LTE-Advanced and eMBMS SFN *)
may resolve the competition for UHF spectrum between broadcast and MBB
Rewards and challenges:
• Massively improved UHF spectrum utilization can free the bandwidth required for digital
inclusion with massive video capacity also for non-linear broadcast content
• Terrestrial broadcast reach extends to smart phones and tablets, to indoors and mobile
• HD capability for terrestrial broadcast based on a global standard
• Interactive TV capability for broadcast including bandwidth required for non-linear content
• Flexibility regarding linear vs. non-linear content
• Shared infrastructure investment into existing base station sites
• Innovation potential in technical, regulatory and business model domains
*) eMBMS SFN: enhanced Multimedia Broadcast Multicast System in Single Frequency Network, efficient technology to broadcast multimedia content in LTE and LTE-Advanced networks

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
