SpectrumLack of spectrum in MobileBroadband makes TDD moreimportant than ever.

PerformanceTD-LTE performanceverified to meet mobileinternet service requirement.

Rapid DevelopmentSo far TD-LTE is advancingtogether with LTE FDD inIndustrialization.

Benefits of TD-LTE

TD-LTE industrialization is supported by operators from Europe, Asia-Pacific, NorthAmerica, etc. TD-LTE trial and pre-commercial networks are under planning. Over 10

trials being planned globally during 2010-2011.
