LTE-Advanced: The Challenges and Opportunities of 'True 4G'

摘要

LTE-Advanced introduces new device and network capabilities that will have a profound influence on the success or failure of next-generation cellular technology. Two of the more critical features are carrier aggregation and enhanced MIMO beamforming, technologies that add significant complexity to device development and bring us much closer to "True 4G." Due to the combination of feature importance and complexity in LTE-Advanced, UE testing takes on a new level of consequence. Realization of LTE-Advanced will not only require updates to existing testing tools, but also the creation of new and innovative tools designed specifically to help drive the success of this next generation of global wireless technology.
