    Linksys has been the number one manufacturer of networking hardware in North American for the past five years (Netgear is second, DLink is third).
    For the CY Q1 2004, retail Wireless LAN sales market share: Linksys 52.2%, Netgear 15.3%, D-Link 12.9%. (NPD Techworld Group) For the CY Q1 2004, retail Home Networking total sales market share: Linksys 50.7%, ahead of Netgear s 16.5%, D-Link 13.2%, Belkin 7.3%, Microsoft 5.1%.  (NPD Techworld Group)
    In May 2003, Linksys announced the release of its new cable gateway device (Linksys router, cable modem and wireless G access point all in one device).
    Comcast is the first broadband provider to ship Linksys' gateway device. Customers can receive the gateway by signing up for Comcast's Home Netoworking service, available in most cities
    The product includes CableHome software (developed by Cable Labs --the industry standard for cable modems) which allows Comcast to provision the line to offer services to consumers--an industry first
    Linksys is the first company to deploy CableHome and sat on the development committee
    The broadband industry has been waiting for CableHome so they can sell services like video on demand, music, gaming, etc
    Small/Medium Enterprises
    Launched the first worldwide VAR program that targets the SME market in the U.S. HOW IS THIS UNIQUE IN THE INDUSTRY? HOW IS THIS SIGNIFICANT TO LINKSYS?
    Residential VoIP
    At the end of August (exact date TBD), Linksys, the consumer division of Cisco Systems, will announce its new VOIP products-an analog telephone adapter and a line of wireless routers that provide consumers with the ability to make phone calls over the Internet.
    These new VOIP products utilize Cisco R&D and are part of Linksys' strategy to bring new IP-based communications and entertainment services and applications into the home.
    As more and more homes deploy broadband, Linksys, is expanding its focus, introducing new products in the areas of home entertainment, communications (VOIP) and home monitoring.
    Linksys is teaming with service providers to help bring VOIP phone services to consumers  The first service provider to make the new Linksys VOIP products available is Vonage. Linksys plans to announce similar agreements and partnerships with other service providers.
    As more service providers adopt VOIP technology, the basis for charging subscribers will transform from the current models, which are based on time and distance, to Internet age models based on bandwidth and services.
  • Similarly, an IP NGN gives the customers a better experience by providing them a much broader range of service opportunities, on-demand, and personalized or tailored to their respective needs. At the same time, it simplifies the service provider’s operational responsibilities while providing them the means to earn more revenue and effectively move up the value chain in their customers’ minds—that’s brand awareness and loyalty.
    Cisco’s IP Next-Generation Network vision and architecture addresses a broad sweeping transformation of a service provider’s network and business. It is intended to deliver a sustainable competitive advantage, and profits for Service Providers by helping them develop and plan their organizations, their specific network architectures, and business models for the future.
    The Cisco IP NGN architecture translates the three layers of convergence mentioned earlier to provide rich, personalized, value-add multimedia services. To do this, service providers need an application layer that interfaces with the customer, a secure network layer that creates and delivers the services, and in between them both, a service control and virtualization layer that orchestrates the delivery, operations, features, and billing of the service itself. Connecting all layers and making their communications as efficient and productive as possible is Intelligent Networking which simplifies the complexity of operating such a network by making it more resilient, integrated, and adaptive. Together, the three layers and Intelligent Networking are able to create a whole greater than the sum of its parts – an IP Next Generation Network.
    Let’s go through each layer in more detail….

    19. 19. Application: Wireless Backhaul Brian Hollister
    20. 20. 20 Increased Bandwidth Demand at Cell Sites • Leased backhaul lines account for as much as 25 percent of some mobile operators’ operating expenses • New architectures and applications will require double the bandwidth in the near term and the demand for more reliability is skyrocketing – Wireless Data: CDMA, HSDPA, & EVDO – Applications: IM, Video, gaming, etc • ILECs faced with meeting this rapid demand cost-effectively in order to stem competitive encroachment
    21. 21. 21 Hurdles Associated with Fiber Based Ethernet • Ethernet posed to be best alternative for mobile operators… problem is ILECs have limited fiber deployments to cell sites – <10% of the 140,000 cell sites in the US have direct fiber connectivity • ILECs struggle with marginal increase in incremental revenue and high cost of fiber deployment for optical based Ethernet • Average fiber build out (e.g. trenching) can cost $50 – 200K, depending on the terrain and distance involved and right-of- way issues • Solution: ILECs will need to leverage their existing copper assets and utilize broadband over copper technology
    22. 22. 22 Broadband over Copper (BBoCu) Backhaul • Aktino & customer win Globalcomm award for innovative cellular backhaul solution • Case Study: – Site fed by 7 DS1s with no additional available copper and required an significant bandwidth upgrade – Fiber build out was to costly to ILEC and the build out wouldn’t meet customer timeframe – Aktino’s MIMO on DMT technology was installed in hours on the same 14 pairs that the previous 7 T1s used and provided capacity for a full DS3 (28 T1s and/or 50Mbps Ethernet on 14 pairs) Central Office or Remote Terminal Cable cross connect HDSL / T1 cards HDSL / T1 cards On a U shape mount 14 Pairs @ 12Kft Feet 7 T1s 28 T1s or 50 Mbps Ethernet Aktino Aktino
    23. 23. 23 Ethernet Broadband over Copper: Summary • Carrier class Ethernet posed to be best alternative for cell site backhaul • Limited deployment of fiber and high cost of new deployment will limited Ethernet availability for years • ILECs will need to leverage existing copper infrastructure in order to stem competitive losses • BBoCu solutions provide ILECs with a tool that provides significant increases in bandwidth and reliability at a fraction of the cost of fiber
