Hossam Salib - Positron Access - Economical 3G/4G/Metro Cells Mobile Backhaul - masterclass d2

  1. 1. Economical 3G/4G/Metro Cells MobileBackhaulCase Study Major European Carrier
  2. 2. Mobile Backhaul Bandwidth Needs are Increasing Wireless Technology Evolution:  2G  Primarily voice  NxT1, up to 8 T1s = 12 Mbps 100  3G LTE  Voice and data  TDM Backhaul 75  Driving need for fiber  10 Mbps up to 25 Mbps backhaul 50  LTE  Broadband  Carrier Ethernet 25 3G  25 Mbps up to 100’s Mbps or more 2G 0 2 2010 Positron Access Solutions - Confidential
  3. 3. Cell Site Backhaul Evolution in North AmericaRequirements:  EVDO / UMTS/HSDPA / LTE demand for More Bandwidth  Demand for Higher Reliability  New Lower Cost Backhaul (Ethernet)Challenges:  Drop in revenue per bit  Value (to end users) of applications not related to data volumes  Current T1 backhaul doesn’t scale Traffic Growth in U.S. Cell Sites Voice Dominant 200,000 183,689 180,000 175,725 Revenue & Traffic 162,986 160,000 De-Coupled 139,338 140,000 127,540 120,000 104,288 100,000 81,698 80,000 65,887 Revenues 60,000 51,600 30,045 40,000 22,663 Data Dominant 20,000 913 0 1985 1987 1989 1991 1993 1995 1997 1999 2001 2003 2005 Source: CTIA Semi-Annual Wireless Industry Indices, December 2005 Edition Time Source: LightReading 3 2010 Positron Access Solutions - Confidential
  4. 4. MIMO-on-DMT – VectoringTechnology
  5. 5. Why Add MIMO?......Real World Copper Plant MimicsWireless World, i.e. Multiple DisturbersWireless Wireline MIMO Tx/Rx CO CPE Copper • Because crosstalk is the biggest link degrader in DSL today • Because MIMO can be effective against legacy disturbers • Because it is a proven technology in wireless 5 Positron Confidential 2010 Positron Access Solutions Positron Confidential
  6. 6. NEXT Mitigation Via Vectoring • For longer loops, NEXT is biggest performance bottleneck today • FDM is effective against NEXT but not against legacy disturbers Noise Alien NEXT MIMO MIMO Channel NEXT Tx H Rx Whitening Signals Signals • MIMO processing exploits NEXT correlation across lines and can mitigate NEXT crosstalk Aktino Confidential 6 2010 Positron Access Solutions Positron Confidential
  7. 7. FEXT Mitigation Via Transmit Pre- Compensation• For shorter loops, self-FEXT is the dominant noise source.• Upstream FEXT can be cancelled at the DSLAM using receiver-based MIMO.• Downstream FEXT can be cancelled at the DSLAM using transmit MIMO pre-compensation.
