India - Telecom Market Going Broadband !
Millions

• Indias Telecom Minister declared 2007 as the
  year of Broadband.
• 13 operators planning to deploy WiMAX including
  TATA/VSNL, BSNL, Bharti, Reliance, Dishnet, Hutch
  and others.
• Many of the broadband subscribers could be
  provided by WiMAX (70 of copper laid can not be
  used for Broadband)
• WiMAX is already being rolled out in India by
  some of the operators based in 3.3 GHz.

Standards Comparison Now ? Future
(1) ITU-PB, 3km/h channel model is assumed (2)
1x2 DL SIMO is assumed for HSPA (3) For Mobile
WiMAX 2x2 MIMO, adaptation of matrix-A/B, MLD
receiver is used, and ideal channel estimation

Nortel Capacity Solution

• Nortel WiMAX MIMO BTS has industry highest
  aggregated cell capacity
• DL 2x2, UL 1x2 10 MHz, N3 - 75 Mbps
• DL 4x2, UL 2x4 10 MHz, N3 - 110 Mbps
• Design targets are set higher to ensure
  implementation margin
• MIMO delivers unique spectral efficiency
• 2-5 times cell capacity increase compared to
  non-MIMO system
• Collaborative MIMO doubles user capacity

Coverage
Nortel delivers throughput and mobility anywhere,
anytime

• Breadth Increased coverage keeps sites cost
  low
• Advanced High Power PA improves downlink
• Diversity reception improves UL coverage
• MIMO flexibility trade DL capacity for UL
  coverage
• Transmit diversity (STTD) extends coverage and
  delivers cell edge signal quality

• Depth Delivering a consistent user experience
• Spatial Multiplexing doubles or quadruples
  performance
• MIMO multi-path ? helps to eliminate urban /
  suburban coverage holes
