Extreme densification of small cells is the key to addressing 1000x challenge. We need to evolve small cells in all directions: all forms – micro, pico, femto, metro, relays etc.; all technologies—3G,4G,Wi-Fi , all integrated; deployments by operators as well as users. The densification begins with the existing spectrum and techniques that are available today, for example, optimizations such as
“Range Expansion” are possible today with HSPA+ and in the future with LTE Advanced networks. Many more enhancements and new deployment models that are needed to reach the 1000x goal are being worked, on as part of standards and product solutions.
Qualcomm has already demonstrated the benefits HSPA+ and LTE Advanced “Range Expansion” at major global events.
