Smartphones and tablet devices are driving huge access network bandwidth usage, while users are demanding high quality, low delay voice and video services with ubiquitous coverage. This increase in bandwidth across limited spectrum is driving a growing number of cell sites which, in turn, puts pressure on mobile operators to find new ways to meet the capex and opex demand.
In this series of sessions, you will explore the market dynamics of the mobile backhaul market, the architecture and applications that are driving business opportunity and the opportunities for broadband network operators and wireline carriers, as well as infrastructure partners and new entrants, to participate in the business of providing affordable, reliable bandwidth for the mobile network operator.

DAY ONE: Wednesday, June 6, 2012
8:00 – 8:25 am
Management of DSL and Wi-Fi from Cloud for Mobile Data Offloading
Wonjong Rhee
Wonjong Rhee, Vice President of Research, ASSIA Inc.
Mobile offloading has been a hot topic since the introduction of smart-phones. Offloading is often achieved through a local DSL broadband service and the associated Wi-Fi. While the basic concepts and benefits of offloading itself have been well recognized, the performance and management problems of the DSL and Wi-Fi connections and the impact to offloading have not been well understood, yet.
This presentation will cover the potential savings and additional revenues through remote management of DSL and Wi-Fi. Recent findings, including performance statistics and unrealized gains, from a cloud side monitoring will be provided. The impact of intelligent optimization over millions of residential Wi-Fi’s will be presented. The limitations of ‘intelligence-in-the-box’ will be explained and compared to the new approach of ‘intelligence-in-the-cloud’. An obvious advantage of cloud solution lies in the accessibility to data and control of millions of Wi-Fi’s, and the implications can be quite surprising even for the experts.
8:30 – 8:55 am
Moving Beyond SNMP and FTP: Optimizing Service OAM Performance Metrics Collection
Brian Hedstrom
Brian Hedstrom, Senior Architect, CableLabs
Many Mobile Operators are obtaining Metro Ethernet services for their mobile backhaul needs. These services often include Service Level Agreements with the Metro Ethernet Network Service Provider to specify service performance objectives. To validate the SLA performance of an Ethernet Virtual Private Line service, for example, the Service Provider performs Service-level Operations, Administration and Maintenance Performance Monitoring measurements for latency, loss and jitter. These measurements are performed at the User Network Interface (UNI) of the MEN in cases where the MEN is a single Service Provider network.
Example collection methods include SNMP polling and FTP file retrieval of vendor proprietary file formats. This presentation proposes a new generation metrics collection architecture and methodology. The goal is to move operators away from vendor proprietary and inefficient solutions to a new, and powerful standards-based approach based on specifications that is better suited for scalable, efficient back office environments.
The intended audience for this presentation includes operators deploying MEF-based services for Mobile Backhaul applications, back office application vendors, and network device vendors.
9:00 – 9:25 am
Safely Blending Broadband, Business and Backhaul: The Service Separation Approach
Kevin Morgan
Kevin Morgan, Director of Product Marketing, Carrier Networks Division, ADTRAN, Inc.
In the past, parallel packet or circuit-based SONET networks would be constructed to ensure each new service did not impact the quality of another—a method that is not only expensive to build and manage, but limits scalability.
Service providers can eliminate the need for capital intensive overlay builds to support 4G backhaul services, optimize their network assets and grow their overall addressable market opportunity in both mobile and residential backhaul applications through scalable service separation. The service separation approach eliminates network bottlenecks by delivering MEF-certified, wavelength separated Ethernet services to residential customers, business customers and cell sites over the same network infrastructure; enabling important service isolation for each individual mobile network operator that may share a single cell site or simultaneously offer residential broadband or business Ethernet, and wholesale backhaul services.
This session will discuss how a service separation utilizes both wavelength and Ethernet switching separation, and how service providers can cost-effectively capitalize on the growing mobile backhaul and residential broadband business opportunities without risking quality-of-service (QoS) issues symptomatic of many multi-service solutions. Attendees will learn how to improve competitiveness as they offer high-performance, scalable broadband and cell site backhaul services at the lowest cost of
9:30 – 10:20 am
Roundtable: The Future of Mobile Backhaul and Possible Alternatives
Glen HuntKevin Morgan
Moderator: Glen Hunt, Service Director, Current Analysis
Rodney Wise, Director of Engineering, Walker and Associates
Jeff White, VP - Multiservice Transport Network Solutions, Ericsson
Kevin Morgan, Director of Product Marketing, Carrier Networks Division, ADTRAN, Inc.
The complications associated with advancing the Mobile Backhaul infrastructure to provide enough bandwidth for 4G usage warrant a quick investigation into the future. The exponential growth of bandwidth in the mobile environment has created some interesting dynamics up until now. This discussion explores what technologies and alternatives may be available over the horizon to help facilitate the next bandwidth rush. Topics for discussion:
- What requirements will come from future base stations?
- What part will WDM play?

Synchronization in the Mobile Backhaul Network
Chuck Perry, Sales Engineer, Symmetricom
Synchronization is the #1 issue for next-gen Mobile Backhaul but nobody is talking about it. This presentation specifically focuses on the synchronization requirements for wireless backhaul applications across native Ethernet based networks within the mobile wireless environment. It describes some of the considerations that have to be taken into account for deployment of PTP into such a network. It also discusses some of the advantages and limitations of packet-based timing technologies, with specific reference to PTP and Sync-E.

NLOS Backhaul for Large Scale Picocell Deployment
John Hoadley, CTO, Taqua
Smartphones and other data-intensive mobile device usage in both the consumer and enterprise markets continue to provide network capacity challenges for operators. The mobile industry is looking to small cell deployments as a principal solution for addressing network capacity challenges, data off-load requirements, and in-building coverage issues. Traditional fiber and line-of-sight microwave cell site backhaul is impractical for the large scale deployment of small outdoor cells (Picocells/Femtocells) because of cost and line of sight issues from trees, buildings, and other urban structures. As a result, the industry is turning to NLOS wireless backhaul as cost-effective, quick and practical way to deploy small cells. Using cost-effective and licensed TDD spectrum to ensure quality of service, NLOS wireless backhaul can be an enabler for deploying small cell in urban, suburban, and rural environments.
4:30 – 5:00 pm
Bonded Copper Backhaul Solution for Metro/Micro Cell
Sankar Ramachandran, Director, Product Marketing, Positron Access
Mobile operators and wireless service providers are experiencing a surge in the upstream/downstream bandwidth traffic pattern similar to that of fixed broadband service providers. The usage of social media sites and on-demand entertainment is higher in mobile networks compared to fixed wireline internet by a factor of 3. This session discusses technology solutions that address the escalating bandwidth needs of the mobile data user, and offers solutions for service providers to flexibly extend the up and downstream metro/micro cell backhaul bandwidth demand as traffic patterns change
