5 Triple Play – Servicios Centrados en el Usuario
By combining multiple products into a single package, the service provider can increase its yearly revenue and discourage subscribers from switching to another provider. Source Light reading 2005: Todos los servicios en un único paquete con una única conexión

Expectativas de ancho de banda tienden a ser mayores

7 Mas y Mas Usuarios están Demandando Banda Ancha

Downstream increase drivers Upstream increase drivers SDTV HDTV Basic HSI Gaming Multimedia surfing Video Conf., learning Home working 2 Mb/s per channel 8-12 Mb/s per channel 5 Mb/s average 2 Mb/s per session 8 Mb/s average 3 Mb/s per session 4 Mb/s average SDTV Basic HSI HDTV Personal content upload Gaming Multimedia surfing Video Conf., learning Remote home monitoring Home working 0.2 Mb/s 2 Mb/s average 0.5 Mb/s 3 Mb/s per channel 2 Mb/s per session 3 Mb/s per session 0.5 Mb/s per call 1 Mb/s average Drivers: HDTV, variable Quality of Service Drivers: Sharing multimedia content (video, audio) What is the traffic load to be expected? To answer this question, operators need to consider the contribution of the different services. The following slides illustrate the assumptions of bandwidth requirements for specific operators. This slide illustrates Alcatel’s perspective on major services traffic from 2008 to Although compression techniques are improving, new IPTV multimedia and peer-to-peer applications are increasing users’ bandwidth needs each year. In order to size the total traffic, several drivers have to be taken into account: When to introduce HDTV? To extend (simultaneous channels)? What are to be the Quality of Service guarantees - in particular latency for gaming, home working, file downloads and uploads? What will be the statistics for peak usage and the resulting bandwidth trade-offs? Each operator will have a different answers based on the service quality that it wants to guarantee, as well as on its service roadmap. The key drivers for bandwidth growth are: The number of simultaneous HDTV channels The demand for peer-to-peer, fast multimedia communications The garanteed speed for gaming and file up/download As shown using concrete examples in the following slides - depending upon the assumptions taken on these drivers - operators will be looking for the following bandwidth requirements: Downstream from 25 Mb/s to 60 Mb/s Upstream from 5Mb/s to 13 Mb/s Se requiere aumentar el Ancho de Banda en lugar de mejorar las técnicas de compresión

9 El Futuro de la Banda Ancha son los Servicios de Triple Play
Video Alta definición y definición standard Multiples set-tops, DVRs, picture-in-picture, mosaic views Gran ancho de banda y alta calidad son requeridos. Voz Tarifas planas. Integrada con y lista de contactos. Bajo ancho de banda y alta calidad son requeridos. Data Gran ancho de banda Tolerancia a grandes retardos y variaciones (Bursty) La velocidad percibida es más importante que la calidad. HSI Tier 2 High Def Standard Def TV 1 Tier 1 TV 2 DVR 1 DVR 2 Data 25 Mb/s Still More Data!! Tier 3 TV 3 100+ 50 Minimum Existing DSL networks were deployed to deliver high-speed Internet access services where the initial service bandwidth was in the Mb/s range. In some markets, it has recently increased to 3 Mb/s. However, consumer demand and competitive pressures are currently leading major ILECs to enhance their access networks in order to deliver the bandwidth required to support IP video services. Many factors must be considered when forecasting downstream bandwidth requirements, such as the number of Standard definition and High definition channels that will need to be supported simultaneously. It is clear that beyond arguments about future video compression performance, bandwidth requirements are increasing by an order of magnitude. Rather than base their business models on being the fastest Internet provider, service providers have introduced bundled voice, video and data services in order to create sustainable customer loyalty and stabilize the top and bottom lines. However, providing a mix of services, like this, places different requirements on the network. Video, unlike voice and Internet, requires high bandwidth and extremely high quality. Voice, unlike video, doesn’t require much in the way of bandwidth and can suffer through minor network impairment. Unlike voice and video, it’s all about speed with Internet access.

12 Nuevos Edificios: Perfecto para desplegar FTTH
Nuevas Redes, Nuevos Edificios (Greenfields) Por que instalar cables de cobre cuando el costo del cable de fibra es menor? Por que usar un ancho de banda medianamente limitado cuando la fibra no ofrece limites? Por que poner electrónica activa en los gabinetes de interior o exterior cuando se puede usar equipo pasivo? Por que usar broadcast orientado a coaxial cuando el modelo del futuro requiere capacidad multimedia? Por que no diferir la mayor parte de los gastos de CAPEX hasta que el abonado sea dado de alta

27 GPON Provides the Bandwidth for Triple Play
Effective Bandwidth Per Subscriber 1,000 GPON Target bandwidth 100 EPON Mb/s per user 10 Possible with Multi-Dwelling Unit ONT (assuming 24 xDSL or CAT5) 1 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 In the PON world, there are essentially two competing standards. One is EPON, which operates at 1.25Gb/s in both directions. The other more recently introduced GPON standard operates at an asymmetric rate of 2.5Gb/s downstream, and 1.25Gb/s upstream. This slide illustrates why service providers are attracted to GPON. Its flexibility enables an average bandwidth of Mb/s per user at a reasonable number of homes served per shared fiber. If less bandwidth is satisfactory, then the number splits can be raised to up to 64 per fiber. Typical number of splits per PON GPON enables long-term service growth
