Workshop Goals

Global forecasts indicate that by 2015 there will be more than 200 live LTE networks in over 70 countries using 38 spectrum frequency combinations. However, the global adoption of LTE services risks being hampered by device interoperability issues unless harmonized spectrum band plans can be achieved.

Despite the disjointed nature of current LTE deployments, there are certain significant trends that indicate the 2.3-2.7GHz LTE bands (i.e. Quad LTE bands 40, 7, 38 and 41) could constitute the first wave of global roaming devices with huge market appeal and the potential of reaching 55% of global population.

In 2012, China's Ministry of Industry and Information Technology announced that the entire 190 MHz of spectrum in the 2.5/2.6 GHz band will be allocated for TD-LTE deployments in China, which harmonizes its TDD spectrum with Japan and the US, two major LTE markets.  In addition, several prominent TD-LTE network deployments in late 2011 and early 2012, including Softbank Japan, Etisalat Mobility and STC in Saudi Arabia and Bharti Airtel in India.  These developments could allow the TD-LTE ecosystem to reach significant economies of scale, boosting further infrastructure and device investments in TD-LTE technology.

Driven by this thriving ecosystem, some analysts are forecasting that TD-LTE subscriptions will surpass 500 million by 2017 and revenues associated with TD-LTE services will reach $91 billion, as more carriers join the TD-LTE ecosystem.

This workshop will consider Smartphone architectures which will support integrated TD-LTE and FD-LTE radios in the same device and discuss challenges, benefits, efficiencies and trade-offs:

  • What are the current global operator considerations for LTE deployment?
  • What are the main drivers behind FDD+TDD handsets other than enhanced roaming opportunities?
  • What are the performance tradeoffs for supporting TD-LTE and FD-LTE in the same device?
  • How many bands can be supported, and which bands must support simultaneous connections?
  • What are the preferred architectures for integrated front-ends and modules supporting TD-LTE and FD-LTE in the 2.3-2.7GHz bands?
  • What innovative technologies and techniques will enable cost-effective global LTE roaming smartphones?
