LTE Advanced is the next major milestone in the evolution of LTE. It incorporates many dimensions of enhancements including the aggregation of multiple radio channels, advanced antenna techniques and others. But most of the gain comes from optimizing HetNets, resulting in better performance from small cells. Qualcomm has prototyped and demonstrated the benefits of LTE Advanced HetNets at global events.
Brings more out of small cells
Small cells such as pico and femtocells bring the network closer to users and provide a big leap in performance. But LTE Advanced optimizes small cell performance through features such as “Range Expansion” to make the leap even more significant. Range Expansion increases the utilization of small cells to increase overall network capacity.
Faster data rates for all users
Simply adding small cells to a network only benefits users close to those cells. But LTE Advanced enhances the user experience for all users with higher data rates, even when the small cells are not positioned in optimal locations. Added to that advanced receivers allow devices to discover small cells early and further increase performance of range expansion.
Dynamically adapts to network load
Network load is inherently uneven—continuously changing with time and location. The Adaptive Interference Management feature of LTE Advanced dynamically allocates resources between the macrocells and small cells to balance load, benefitting all on the HetNet.
More carriers means more speed
LTE Advanced can aggregate up to 5 carriers (up to 100 MHz) to increase user data rates and capacity for busty applications such as web browsing. Aggregation (multicarrier) when combined with higher order MIMO can provide extremely high peak data rates, theoretically up to 1Gbps.
Qualcomm is an LTE Advanced leader
We’ve established a state-of-the-art, over-the-air test network in San Diego to evaluate and prototype LTE Advanced HetNet features. The performance of this network was demonstrated at MWC2012.
