Chair: Amit Butala
Organizer: Firouz Behnamfar, Amit Butala

Session Abstract:LTE-U, or as more recently rechristened LTE - Licensed Assisted Access, has attracted a lot of attention, both positive and negative, from network operators, traditional wi-fi vendors and enterprises. But what is it all about? And how will it help alleviate the mobile data rate crunch? We will have two experts from Intel and Qualcomm share the inside picture on how it's shaping up.

Speaker: Apostolos (Tolis) Papathanassiou

Bio: Principal Wireless Architect at Intel.
Tolis is responsible for LTE PHY (Physical Layer) standardization and technology development activities in the Standards and Advanced Technology (SAT) division of Intels Mobile and Communications Group (MCG). He has more than 50 scientific contributions to international journals, conferences, and books since 1994, more than 20 awarded patents/patent applications in 3G (TDSCDMA and WCDMA), 4G (WiMAX, LTE), satellite (LEO/MEO), and Wi-Fi (IEEE 802.11a/g/n) wireless communications systems since 1996, and more than 100 contributions to wireless standardization bodies such as 3GPP, IEEE 802.11, IEEE 802.16, and WiMAX Forum since 1999. Previously at Intel, he led multiple standardization efforts in ITU-R and IEEE/WiMAX Forum. Before joining Intel, Tolis worked on multiple-antenna PHY techniques and algorithms for 3G, satellite, and Wi-Fi wireless systems.

Title: LTE System Deployment and Performance in Unlicensed Bands

Abstract: The ever increasing demand for mobile data is fueling a new wave of innovations to increase the capacity of cellular networks. As opportunities for conventional licensed spectrum below 6 GHz are becoming scarce, other spectrum frequency bands, such as unlicensed bands, have gained considerable attention recently. In order to enable the best possible system operation in unlicensed bands, design issues with respect to co-existence among multiple LTE operators sharing the unlicensed band as well as co-existence with other wireless systems, such as IEEE 802.11, need to be addressed. In this presentation, we evaluate the overall system level performance in unlicensed bands by proposing appropriate deployment scenarios. Different LTE and WiFi system configurations are described and evaluated in LTE/WiFi coexistence scenarios, including multiple LTE operator coexistence, demonstrating important system-level performance aspects in unlicensed bands.

Speaker: Kai Tang

Bio: Director, Technical Marketing at Qualcomm.
Kai's current role is responsible to promote LTE evolution and small cell technology to operators and infra vendors, with a focus on North America. Previously he has helped to drive the adoption of key Qualcomm technologies including LTE and LTE-Advanced, DO-Advanced, 1X-Advanced, Femtocells and UltraSON. Kai joined Qualcomm in 2001 as a system engineer in the mobile chipset division. He has participated in the design and testing of multiple Qualcomm chipsets, spanning gpsOne, 1X/EV-DO and UMTS technologies. Kai holds a PhD in Electrical Engineering and an MBA degree, both from University of California, San Diego. He received his BS and MS degree in Electrical Engineering from Southeast University, China. He holds 5 US patents related to wireless communications.

Title: Extending the benefits of LTE Advanced to unlicensed spectrum

Abstract: Bringing LTE Advanced to unlicensed spectrum allows operators to better utilize the unlicensed 5 GHz band through a unified LTE network and offer higher network performance, as well as an enhanced user experience. In this presentation, we will introduce LTE-U use cases, regulatory requirements and standardization status. We will also present LTE-U performance and benefits, and how it would coexist with WiFi in the unlicensed band.
