Title: FTTP/GPON

Speaker: Don McCullough, VP Marketing, Ericsson

Abstract:
Telecom carriers are upgrading their access networks, or last mile, to offer competitive new service such as VoIP, IPTV and high speed data services. After a decade of getting more bandwidth out of their copper plant using DSL technology, carriers are turning to fiber using Passive Optical Networks or PONs to get even more. Verizon has deployed PON to over 3M customers; carriers in Asia have deployed even more PON. But a new global standard is emerging, Gigabit PON or GPON. This presentation will show an over view of existing PON standards, Broadband PON (B-PON) and Ethernet PON (EPON), as well as GPON. It will provide market approaches to the various PON technologies and will present technology differences between them. Finally, the presentation will try to make sense of the directions that the PON market is likely to take over the next few years.

Biography: As VP of marketing, Don leads out-bound marketing and product management for the GPON product line at Ericsson. Don joined Ericsson along with the rest of the Entrisphere team in February 2007 when Ericsson acquired Entrisphere. Prior to the acquisition Don had been the Director and then VP of marketing for Entrisphere since 2003. He has 18 years of experience in developing and marketing high-bandwidth telecom access systems to deliver the triple play of services. He has worked in both start ups and public companies. Don holds an MBA from the Fuqua School of Business at Duke University.

Biography: Joakim Wiklund is a wireless technology veteran, bringing to Sonim invaluable experience in mobile networks and wireless data applications. He spent over 15 years in various technical, product and line management roles with the leading mobile system giant, Ericsson. He was one of the founding members of Ericsson�s GPRS team based in Stockholm, Sweden that built and delivered the first GPRS end-to-end network solution, with full responsibility on the technology aspect of the product. Joakim was also one of the founding members of the 3G.IP initiative. 3G.IP was a group of operators and vendors that shared a common 3G network architecture strategy. Contributions from 3G.IP members resulted in successful completion of Release 5 of IP Multimedia Subsystem (IMS) in 3GPP, in 2002. Joakim moved to the U.S. in early 2000 as Director of Ericsson�s Wireless Center in Silicon Valley, spearheading the company�s initiatives on wireless data solutions and applications. Before joining Sonim, Joakim worked closely with the company as Ericsson�s Liaison Officer. He was very instrumental in guiding the Ericsson Sonim OEM relationship and Sonim�s contribution to the Push to talk over Cellular (PoC) standard development.

Title: A Simulation Model for IEEE 802.11n

Speaker:Thomas Paul

Abstract: In an effort to improve the performance of Wireless LAN (WLAN) devices, the IEEE (Institute of Electrical and Electronics Engineers), in late 2003, formed a task group, TGn, to work on a new specification: 802.11n. The goal was to deliver speeds of at least 100Mbps, which would more than double the existing maximum rate of 54Mbps provided by the 802.11a and 802.11g amendments. Currently, the 802.11n draft (standard still under development) offers rates up to 600Mbps through the use of MIMO (multiple-input, multiple-output) antenna structures.

In this presentation, we discuss the signal processing techniques used to achieve these rates over indoor wireless environments. Techniques discussed include space-time coding, channel estimation, beamforming, and MIMO detection, including linear and ML detectors. A simulation model developed using Matlab/SIMULINK implementing the transmitter-receiver system is also presented.

Biography: Thomas Paul has worked in the communications industry since 1996. Most recently, he worked at Atheros Communications on the development of Wi-Fi phone products. Prior to that, at Ralink Technology, he worked on development of a low-cost version of the 802.11b WLAN chipset. Earlier, at PC-TEL Inc., he worked on the maintenance and improvement of their V.92 software modem product, attaining the position of Project Lead � Product Enhancement. He also holds a U.S. Patent regarding dynamic block processing in software modems. He earned his B.A.Sc. degree at the University of Toronto, Canada in 1996. He is currently a graduate student in Electrical Engineering at Santa Clara University.
