  3. 3. Market Overview Trends and Figures
  4. 4. Towards Carrier Ethernet RAN Backhaul Decouple the capacity growth from the OPEX and CAPEX in the transport network Heavy reading, May 2007 Carrier Ethernet Services emerge as the natural choice. Central Office Ethernet Switch Ethernet Ethernet Backhaul Cellular Base Station
  5. 5. Ethernet Mobile Backhaul is Forecast to Soar Mobile operators shell out $19.5B in mobile backhaul service charges in 2006 Infonetics Research, April 2007 The cost per mobile backhaul connection for leased lines PDH and ATM over PDH is about two and a half times that of new wireline connections (Ethernet, DSL, cable, PON), now and in 2010 Ethernet makes up just 1% of total mobile backhaul equipment revenue in 2006, but is forecast to soar to $2.5 billion by 2010, at which time it will represent 41% of the market The MEF Work
  6. 6. Mobile Backhaul Network Market <ul><li>Qualitative estimates for markets </li></ul><ul><ul><li>US: ca. 90% leased lines </li></ul></ul><ul><ul><li>Middle East & Africa: ca. 90% microwave radio links </li></ul></ul><ul><ul><li>Europe: ca. 60% microwave radio links </li></ul></ul><ul><ul><li>World: 50% to 60% microwave radio links </li></ul></ul><ul><ul><li>Carrier Ethernet implementation divided roughly equal between Copper/Fiber and Wireless media </li></ul></ul><ul><li>Projected growth focus of mobile access networks </li></ul><ul><ul><li>US & Europe: Increase in bandwidth only to existing sites </li></ul></ul><ul><ul><li>Emerging markets: Build-out of new access and backhaul networks </li></ul></ul><ul><ul><li>Carrier Ethernet plays an important role in network growth planning </li></ul></ul><ul><li>MEF work for mobile industry is relevant and timely </li></ul>
