  1. Evolving Broadband Technologies By Vijay Madan

  2. Services Classifications/Types • Individual, Enterprise, Community • Fixed, Mobile • Real Time, Non-Real Time • Broadcast, Interactive, Information • Symmetrical, Asymmetrical (Uplink-Downlink) • Triple Play • Internet, Entertainment

  3. Broadband Services • People of Same Household Online Simultaneously • Browsing Web, Downloading Information and Updates • (Symmetrical & Asymmetrical- Interactive Services) • High Speed Streaming Video on Televisions & Computers • Internet Access, Cable Television Service, and Wire-line • Voice preferably from the same Company • Video Chat Rooms for Video Calls, Music Videos, Infomercials, Distance • Education, News Clips in Residential Areas • Virtual Presence for Interactive Business • Virtual Ubiquitous Global Offices for Business • Virtual Private Networking, Database Access, e-Commerce • Instantaneous Availability of Information from Anywhere to Everywhere

  4. Broadband Triple Play • Triple play? • TV, Internet, Phone ( Video as part of TV & Internet) ISP/Telco Model Computer/Telephone Centric Cable Model TV Centric Cost of accessing services may only be related to type of services and not to the city or distance from the local point of service • MSO (multi-service operators) investing not only in networks, equipment and external plant but also in application servers, delivery mechanisms, content, application development, additional build-ups ?

  5. Interesting Broadband Scenarios • Hong Kong Population 6.8 million, Household 2.2 million Broadband connections 1.2 million (1.1 million house hold) 14 DSL lines/100 population; 28 DSL lines per 100 telephone lines • In Japan BB driven by content for different age groups • In Korea BB driven significantly by local content • Access owner- service provider - content provider • Revenue as ratio of investment in that order • In India BB may be driven by Entertainment: Interactive TV , time-shift TV, video on demand, music on demand, multiplayer gaming, education at home, sky shop rather than internet shopping. Of course net browsing and data transfer. • How much symmetrical !

  6. The Intelligent Services Layer of the Networks Shared Library of Services on Internet Third Party Content Customers Service Plane = Service and Application Layers Service Control Logic out of switching/routing systems Service nodes used as shared resources Transport Layer of Telecommunication Network Transparency of Layers to make Design and Deployment of New Services Almost Instantaneous

  7. Broadband Access Packet NW End point G Way Infrastructure Gateways Premise End Points

  8. Broadband Technologies • Cable • DSL • VDSL • FTTX, PON, GPON, EPON, APON, AON • PLC • Satellite - Return • LMDS • DTH- Return • Licensed Wireless FWA • Unlicensed Wireless WiFi, WiMAX • 3G Wireless • Beyond 3G wireless
