4 G World 2012 Global Multimode Carrier Aggregation
2 likes•719 views
The document discusses the challenges of providing global LTE connectivity given the many cellular standards, voice modes, and radio frequency bands deployed worldwide. It outlines Qualcomm's solutions to enable seamless mobility across the broadest set of technologies and bands, including integrated multimode chipsets supporting up to 40 LTE and 3G bands along with Wi-Fi, Bluetooth, and GPS. Carrier aggregation is also discussed as a way to accelerate LTE speeds given fragmented spectrum holdings.
