Evolving and expanding into new frontiers.
Qualcomm Technologies ushered in the LTE Advanced era with its industry-first Qualcomm® Gobi™ modem chipsets supporting carrier aggregation. Apart from carrier aggregation, this critical component of 1000x challenge also brings antenna and small cell enhancements. LTE Advanced continues to evolve, offering even higher performance and expanding into many new areas such as unlicensed spectrum, direct device-to-device, terrestrial TV and more.

LTE Advanced, a critical component of 1000x mobile data challenge, launched in June 2013, powered by Qualcomm Technologies' third generation Gobi modems, integrated into The Qualcomm® Snapdragon™ processor 800 solution. While LTE Advanced is rapidly gaining momentum worldwide, the industry is busy with its evolution, which not only further improves the performance through enhanced receivers and other features, but also expands LTE into many new areas, such as bringing it into unlicensed spectrum, direct device-to-device, terrestrial broadcast TV and more. Qualcomm Technologies has successfully prototyped and demonstrated the benefits of LTE Advanced at many global events, including showcasing HetNets with enhanced receivers at MWC2014.
More carriers means more speed and more capacity.
LTE Advanced can aggregate up to five carriers (up to 100 MHz) to increase user data rates for all users and increase capacity for bursty applications.
As a first step, the aggregation of two 10 MHz carriers, enabling 150 Mbps (Cat 4) peak data rate was launched in In June 2013, powered by Qualcomm Technologies' Snapdragon 800 chipsets integrated with the third generation Gobi LTE modems. Following up on that, fourth generation Qualcomm Gobi™ LTE modem 9x35 was announced in Nov 2013, aggregating two 20 MHz carrier enabling 300 Mbps peak data rate (Cat 6).
Carrier aggregation continues to evolve, supporting aggregation across FDD/TDD, across cells (Multiflow) , and across licensed and unlicensed bands.

Enabling hyper-dense HetNets.
The anticipated 1000x capacity increase warrants hyper-dense small cells deployments. But it is not just about adding small cells. LTE Advanced optimizes small cell performance through features such as “Range Expansion” to ensure that capacity scales with the amount of densification. This is possible only with advanced interference management techniques such as FeICIC/IC. This has two components: FeICIC that provides interference coordination between small cells, on the network side; IC which cancels interference on common channels, on the device side.

Enhanced receivers for superior LTE Advanced performance.
Enhanced receivers play a pivotal role in further improving LTE Advanced. For example, devices that cancel inter-cell interference on both common and data channels provide more capacity and better data rates, especially at cell-edges, thereby increasing the user experience. Interference cancellation is even more beneficial at managing interference in dense small cell deployments, significantly increasing their overall performance.
Advanced antenna techniques such as higher-order MIMO are also part of LTE Advanced (up to 8x8 MIMO defined). From today's 2x2 MIMO configuration the logical next step is to implement 4x receive diversity, which brings most of the gain for four antennas.
LTE Advanced expanding into new frontiers.
Supported by its vast and ever growing ecosystem, LTE Advanced is not only continuing to improve performance through enhanced receivers, even better HetNets, but also expanding into many new areas beyond traditional mobile broadband. Extending LTE Advanced to unlicensed spectrum, LTE Direct for proximity based direct device-to-device discovery, LTE Broadcast as a platform for terrestrial TV are some examples of such expansion.
So, LTE Advanced is not mere collection of few 3GPP releases, but will continue evolve and will play a pivotal role in the future of wireless for many years to come.

Extending LTE Advanced to Unlicensed spectrum.
Bringing the higher performance and robust mobility of LTE Advanced to unlicensed spectrum immensely benefits both 3G/4G operators and users. Operators can leverage both licensed and unlicensed spectrum using a unified network to augment data capacity while providing the tightest possible interworking between the two. Users get seamless broadband experience and robust connectivity because of a mandatory anchor in the licensed spectrum.
LTE Advanced in unlicensed spectrum targets bandwidth-rich 5 GHz band and can be deployed in countries such as the USA, Korea and China with existing standards (3GPP Rel 10) and existing core network. Other countries need standard modifications to meet regulatory requirements (targeted for Rel 13).
