Global Operators Joint Force to PromoteTD-LTE Global Development
Globla ScaleConverged LTE FDD/TDDstandard is the main streamof BWA technologies;
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.
