• Fractional Frequency Reuse (FFR)

  provides more flexible tradeoff between            with reuse 1/1               with static reuse 1/3
  overall capacity and cell edge rates
   – Users at cell edge are put in reuse with              FFR allows more flexibility in cell
     respect to the strongest interfering sectors          edge/capacity tradeoff
   – Can be applied both in FL and RL
• Dynamic FFR scheme allows complexity
  and performance tradeoff
   – Dynamic scheme allows the scheduler to

Flexband For Increased Cell Edge Data Rates
 • Traditional frequency reuse schemes completely shut off unused
   subcarriers in one sector
    – Suboptimum tradeoff between capacity and cell-edge data rates
 • Intelligent power tiering among subcarriers used in different
   sectors can be used to eliminate cell boundaries
 • FL Scheduler schedules users closer to the AP to subcarriers with
   lower power, and cell-edge users to subcarriers with more power
    – Eliminate ‘cell edges’

RL Power Control for Dynamic Interference
Management
• Power control with regular Other Sector
  Interference (OSI) indications results in:
   – Higher received power per tone for strong users
       •   Higher RL spectral efficiency
   – Lower received power per tone for cell edge users
       •   Interference to nearby sectors are reduced
   – Tight control of interference distribution for QoS users
• Power control with Fast OSI indications enable
  more dynamic control of power levels in bursty
  traffic situations
• Scheduling ensures fairness in data rates across
  users




                                                                23
UMB Supports MIMO, SDMA and Beamforming

• UMB simultaneously supports SISO and MIMO users
• MIMO enables very high data rate transmissions to users close to the AP
• Beamforming increases user data rates by focusing the transmit power to
  the direction of the user, enabling higher receive SINR at the terminal
• SDMA increases sector capacity by allowing simultaneous transmissions
  to multiple users that can be spatially separated
• Beamforming along with MIMO and SDMA provides higher user data rates
  at both high and low SINR regions

UMB vs WiMAX


• Not all OFDMA systems are equal.


• There is significant differentiation possible in the MAC
  design.

WiMAX – Key Observations (1)
The commercial viability of WiMAX will depend upon a myriad of factors

 1. WiMAX marketing is built upon unrealistic and inconsistent
    promises

 2. Mobile WiMAX unable to match the performance advantage of 3G
    Evolution

 3. Fixed WiMAX and Mobile WiMAX are two incompatible technologies
    with different market opportunities and business models

 4. WiMAX is fragmented in many ways and will not benefit from
    economies of scale

 5. Mobile WiMAX Market opportunity is unclear



                                                                     44
WiMAX Key Observations (2) Expanded
The commercial viability of WiMAX will depend upon a myriad of factors

 1. WiMAX marketing is built upon unrealistic and inconsistent promises
     –   1/10th cost & 10x performance claimed by Intel, Sprint-Nextel
     –   1/3rd cost & 3x performance claimed by Nortel !!
 2. Mobile WiMAX unable to match the performance advantage of 3G Evolution
     –   Lower Spectral Efficiency   Lower data throughput
     –   Weaker Link Budget     Needs more cell sites
     –   Higher Latencies    Poor VoIP capacity & data performance
 3. Fixed WiMAX and Mobile WiMAX are two incompatible technologies with
    different market opportunities and business models
     –   Fixed WiMAX based on OFDM while Mobile WiMAX is based on OFDMA
     –   WiMAX may end up working in fixed environments in certain markets.
     –   Mobile WiMAX will find it difficult to compete against 3G.
     –   Delays in interoperability testing, affordable devices, ubiquitous coverage, differentiated
         mobile services etc., will impact the adoption of Mobile WiMAX.
 4. WiMAX is fragmented and will not benefit from economies of scale
     –   Wide range of implementation options and profiles
     –   Incompatibility between fixed and mobile solutions
     –   Lack of harmonized spectrum globally
 5. Mobile WiMAX Market opportunity is unclear
     –   Modest growth forecasts from Yankee Group (28M by 2011)

                                                                                                       45
Mobile WiMAX Technical Deficiencies
• Mobile WiMAX is poorly designed for mobility
   – Lower Spectral Efficiency: 3G has 2x-3x advantage
      • Leads to lower throughputs
   – Poorer link budget: ~10 dB less than 3G systems
      • Leads to poor coverage (1/6th of 3G coverage), hence more cell sites than 3G (6x)
   – Higher overheads than 3G systems
      • Leads to higher latencies and poor support for real time applications
      • Poor VoIP capacity and mixed voice/data performance
      • Limited number of simultaneous users
   – Limited support for handoffs
      • Primarily hard handoffs
• Network and air-interface interoperability
   – Service interoperability needs to be worked outside 802.16, IEEE Standard
     only specifies PHY and MAC layers
      • Leads to poor interoperability and deployment delays

     3G is well optimized for mobility and delivers superior voice and
                      data performance than WiMAX
                                                                                      46
UMB vs. Mobile WiMAX: Key Issues

         Features                    Mobile WiMAX

     Handoffs        • Mobility not an inherent part of initial design
                        – Weak & Unreliable handoff design


     Reverse Link    • Slow Message Based Power Control
                     • No power control for other-sector interference
                       management.
                        – Reduction in RL margin and throughput


     Forward Link    • High System/Signaling Overhead.
                     • Poor support for real-time services.

     Battery Power   • Inefficient message based sleep mode
     Consumption       operation
                         – Idle State Duty Cycle of WiMAX is 9-14 times
                            higher than UMB




                                                                          47

Conclusions
• EV-DO and HSPA technologies are delivering mobile broadband
  today!
   –   Established strongly with major commercial investments
   –   Thriving on a robust 3G eco-system and economies of scale
   –   Proven high performance with a strong backward compatibility framework
   –   Providing services with extensive range of devices
   –   Significant time-to-market advantage over competing alternatives

• Mobile WiMAX offers no advantage over DO/HSDPA mobile
  broadband

• Leveraging on a strong 3G Eco-System, UMB as a highly
  optimized OFDMA provides ultra fast user experience and
  maximizes revenues from all segments
   – UMB and LTE provide more advantages for mobility, capacity, VoIP and real-
     time application support with low latency.

• LTE is designed as an optimized OFDMA solution for Mobile
  Broadband but its commercial realization may be further away
 DO & HSDPA are logical mobile broadband choices to an operator today!!
