Primary Enabling Infrastructure For The Mobile Internet Presented by: Ian Serrao Director – Network Services Columbus Communications Trinidad Ltd. Mobile Industry Observations • Currently Over 3 billion mobile phone users, estimated to grow to 5 billion in 2010 – Growing dependence on mobile connectivity – Demand for Data mobility – Significant increase in Data, video and application development • Traffic growing exponentially due to consumer demand for mobile data services for e-mail, text messaging, web access etc • Push for more bandwidth accelerated by new handsets such as iPhones that combine digital media entertainment with web based applications Source: Infonetics Research, 2008 Analyst Predictions, Statistics and Trends • Demand for bandwidth will grow exponentially while revenue for the operator will taper off • Carriers are exploring various technologies to provide cheaper and more effective ways to meet the capacity growth at a lower CAPEX and OPEX cost • Evolution towards Ethernet/IP based mobile solutions • Bandwidth demands – – – – Mobile Call -16k, Text Messaging– 9.6 -240k Web browsing – 128-384k (min) Media Streaming – 2-15 Mbps Traffic Gap Gap between between traffic Gap between traffic traffic revenue andand revenue increases Revenues Voice Dominant Data Dominant Worldwide Cell Site Connections Growing Worldwide M obile 1st M ile Backhaul Connections: Installed vs New 5,000 Connections (K) • 2006 = 2.9 million • 2010 = 4.8 million • Ethernet fastest growing through 2010 4,000 3,000 New connections Installed connections 2,000 1,000 0 CY05 • Installed WW connections • Mobile operators pay incremental charges for 2x to 10x bandwidth • New options solve major problem for operators CY06 CY07 CY08 CY09 CY10 Calendar Year Source: Infonetics Research Mobile Backhaul Equipment, Installed Base & Services, 2007 Backhaul the Critical Link •The Mobile Backhaul network : • Is the critical link between the mobile subscriber and the network or the Internet • Links the remote base stations and cell towers to the mobile operators core networks • Provide access to both the voice network and the internet Copper Fiber Wireless handset Carrier Base Station Mobile Switching Office (provisioning, call routing, etc) Mobile Evolution With downstream data rates capable of delivering a theoretical 14.4 Mbps of user throughput, the demand for bandwidth in the backhaul network is increasing by an order of magnitude from where it is today Impact of New Services on Backhaul Circuits • New services provide additional capabilities but require more bandwidth. • T1/E1 TDM Backhaul Circuits traditionally used are ideal for carrying high-value voice services but are not optimized for high bandwidth data services. • Backhaul links are becoming congested Possible Solutions • Separate mobile voice services directly at the cell site. • Data traffic can be backhauled using lower cost broadband technologies (xDSL, cable modem, Carrier Ethernet) • Migrate all services voice and data to a single platform that meets all the needs required to deliver service to the customer The Future of Mobile Backhaul • Economic advantages of Ethernet will lead to its widespread use for mobile backhaul networks • Introduction of Ethernet and IP interfaces in mobile base stations and radio controller equipment • Migration of legacy TDM circuits to Carrier Ethernet Solutions • Global Consensus and Adoption of Carrier Ethernet Standards Advantages of Carrier Ethernet Backhaul • Ethernet • Most mobile data traffic is broadband/IP centric • Overcomes TDM (T1/E1) scalability – Economically meets exploding bandwidth requirements currently constrained by the prohibitive costs of legacy network upgrades – Efficient and simple for service providers to manage and maintain – Reliable with full SLA support and full OAM capabilities – Ethernet is optimized for packet data traffic – This makes Carrier Ethernet the compelling choice • Packet can be extended to the cell site over other physical technologies: – – – – • WiMAX xDSL Bonded Copper GPON/EPON Time/urgency – Ethernet NodeB’s are being deployed now by all major networks – Carrier Ethernet removes the barrier for timely network upgrades Ethernet Options Solve Backhaul Cost Problem Worldwide M obile 1st M ile Backhaul Service Charges per Connection: PDH and ATM over PDH vs New Wireline • Ethernet wire-line costs grow gently with large bandwidth increases (Eth, DSL, PON, cable) $40,000 $37,044 Stay on PDH Revenue $30,000 PDH and ATM over PDH $20,000 New wireline Ethernet $10,000 $6,887 $0 CY05 CY06 CY07 CY08 CY09 • PDH (T1/E1 etc.) costs climb directly with bandwidth • New IP/Ethernet wire-line options to satisfy the the #1 investment driver: operational cost savings CY10 Calendar Year Source: Infonetics Research Mobile Backhaul Equipment, Installed Base, and Services, 2007 Traditional Transport Core Site Agg Site

must be planned well before provisioning Separate networks for backhaul and core Pseudowires – The solution to the Internetworking Challenge • Enable the use of new packet networks • Provides a choice among multiple available packet network technologies • Uniquely combine circuit emulation and service emulation over a packet network • Deliver a solution allowing the transport of TDM, HDLC, and ATM
