■ クアルコムは2月26日(米国時間)に、スモールセル及びモバイル端末へのLTE-U(アンライセス周波数帯でのLTE)のインテグレーションによりLTE-Uのエコシステムを促進し、また、LTE-UのWi-Fiとの共存を実証したことを発表しました。

◆ LTE-Uをスモールセルソリューションに統合

・スモールセル向けSoCであるFSM99xxにLTE-U機能を追加し、2015年後半に利用可能となる予定
・アンライセンス5GHz帯のLTE-Uに対応するモールセル用初の専用RFソリューションであるFTR8950も発表

◆ モバイル端末向けLTE-U用RFトランシーバー

・ 業界初となるアンライセンス5GHz LTE-Uに対応したモバイル端末用RF専用ソリューションWTR3950を発表
・ WTR3950はWTR3925と合わせて利用することでライセンス周波数帯とアンライセンス周波数帯の3x20MHzキャリアアグリゲーションに対応し、5GHz帯イントラバンドの連続40MHzのキャリアアグリゲーションにも対応
・ 商用サンプルは2015年後半出荷予定

◆ LTE-UとWi-Fiの共存

・米国サンディエゴ本社で5GHzアンライセンス周波数帯に複数のWi-FiアクセスポイントとLTE-Uのスモールセルを配置してのトライアルにより、実環境での性能と干渉の評価を複数のシナリオで実施

Qualcomm Extends LTE to Unlicensed Spectrum to Enhance Mobile Experiences and Help Operators Meet Network Capacity Demand
Qualcomm Technologies Advances LTE-U Ecosystem with Integration into Small Cells and Mobile Devices, and Proves Co-existence with Wi-Fi

SAN DIEGO, CALIF. - February 26, 2015 - To address the increasing demand for mobile data, Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated (NASDAQ: QCOM) is extending LTE to unlicensed spectrum (LTE-U), and today announced that it has integrated the technology into its latest small cell solutions and RF transceivers for mobile devices. Qualcomm Technologies also announced that it successfully completed over-the-air testing to prove co-existence between multiple LTE-U and Wi-Fi access points in the unlicensed spectrum under extreme load conditions. Qualcomm Technologies will showcase its new solutions with a number of LTE-U demonstrations at Mobile World Congress, March 2-5 in Barcelona, Spain.

“As the Internet enters a new phase of growth, in which more devices are connected and share richer data, there is a need to cost effectively address the challenges of a 1000x increase in mobile data traffic. To do this, we need a combination of more spectrum, more efficient use of existing spectrum, and more small cells,” said Matt Grob, executive vice president, Qualcomm Technologies, Inc., and chief technology officer. “Our job is to help the industry make the best use of all available spectrum, using both LTE and Wi-Fi technologies, to increase capacity.”

Extending LTE Advanced to unlicensed spectrum helps operators meet increased capacity needs and enhance their mobile broadband services. LTE-U is designed to augment operators’ services to use channels in the less crowded 5 GHz unlicensed bands, and uses several coexistence features to support fair share use among the multiple users and technologies that access those bands.

Extending the benefits of LTE to unlicensed spectrum is designed to provide:
* Reliable and predictable performance with an anchor in the licensed spectrum;
* Seamless user experience/mobility;
* Better performance than either LTE or Wi-Fi used individually, with longer range and more capacity; and,
* Additional capacity for carriers to augment mobile broadband.

Integration of LTE-U into Qualcomm Technologies small cells solutions portfolio
Qualcomm Technologies is announcing the first integration of LTE-U into a small cell SoC to expand capacity and seamlessly extend LTE networks. The FSM99xx, a family of small cell SoCs, will add LTE-U and be available in the second half of 2015. The FSM99xx solutions integrate Qualcomm Technologies’ 3G and 4G and support its Qualcomm(r) VIVE(tm) 802.11ac/n Wi-Fi to enable full-featured small cells that provide superior performance with greater power efficiency.

“The FSM99xx family is designed to bring outdoor, enterprise and small and medium business access points to the next level of value and performance,” said Neville Meijers, vice president of business development, Qualcomm Technologies, Inc. “Adding LTE-U technology to our small cell solutions will provide additional capacity for operators to augment existing mobile broadband and deliver seamless connectivity experiences.”

Along with integration of LTE-U into the FSM99xx product family, Qualcomm Technologies is announcing the FTR8950 as the first dedicated RF solution for small cells designed to meet the requirements of LTE-U operation and network listen in unlicensed 5 GHz bands. Qualcomm Technologies’ newest small cell RF transceiver is a successor to the FTR8900 RFIC and supports features such as digital pre-distortion and dedicated network listen.

First announced commercial RF transceiver for LTE-U
Qualcomm Technologies is also announcing the WTR3950 as the industry’s first dedicated RF solution for mobile devices designed to meet the requirements of LTE-U operation in unlicensed 5 GHz bands. Qualcomm Technologies’ newest 28 nm RF transceiver offers an industry-leading footprint and will be commercially sampling in the second half of 2015.

The WTR3950 extends Qualcomm Technologies’ RF product leadership in LTE Advanced, which is based on successful commercialization of single-chip RF transceivers for LTE carrier aggregation. The WTR3950 pairs with the WTR3925, the first 28 nm RF for single chip Cat 6 carrier aggregation, to support up to 3x20 MHz carrier aggregation across licensed and unlicensed spectrum. The WTR3950 can also support up to 40 MHz intra-band contiguous carrier aggregation in the 5 GHz bands.

Successful testing of LTE-U and Wi-Fi coexistence
In order for LTE-U to provide maximum benefit, it must operate harmoniously alongside billions of existing Wi-Fi devices. Qualcomm Technologies is working to integrate LTE and Wi-Fi at the system level, and employs a robust set of protection features to promote the best possible co-existence between LTE-U and Wi-Fi networks. These innovations are designed to ensure users can connect to the Internet however they prefer, while operators can make unified use of all available spectrum to increase capacity. This is designed to result in easier and cost-effective network deployment and operations for carriers and a seamless experience for their consumers.

In its San Diego, Calif. headquarters, Qualcomm Technologies engineers deployed a state-of-the-art network comprising multiple Wi-Fi access points and LTE-U small cells - all operating in a single channel in the unlicensed 5GHz band - to evaluate real-life performance and interference in multiple scenarios. After extensive testing that replicated extremely dense radio conditions, the data concluded that LTE-U can not only provide superior performance than either LTE or Wi-Fi used individually, but fairly coexists with Wi-Fi. In many cases, shifting traffic from Wi-Fi to LTE-U can actually improve performance for Wi-Fi users, due to the efficient way that LTE uses the unlicensed spectrum.

Testing scenarios included both “adaptive duty-cycle” based coexistence which is suitable for commercial LTE-U deployments in countries such as the US, China and Korea using LTE Release 10 and beyond, as well as Listen Before Talk (LBT) based techniques that are proposed through a work item for an upcoming release of the LTE standard, Release 13, which is expected to define a version of LTE-U known as Licensed-Assisted Access (LAA), suitable for deployments in other regions such as Europe and Japan
