Outline

• Main themes
• Broadband wireless Residential market
  characteristics and trends
• Technology trends to address market needs
• Airspans response
• Conclusion

3
Main themes

• Broadband wireless is happening now
• Combining voice AND data is the key to a
  successful business model
• The introduction of residential broadband
  wireless will drive volumes up and costs down
• Many systems deployed already especially in
  3.5GHz, PCS and MMDS bands

4
Residential market characteristics and trends

• Data speeds comparable to DSL
• 512k today 2Mbit/s by end 2001
• 4X year-on-year speed increases!
• Distance independence from exchange
• A uniform service must be delivered by the
  operator significant numbers of residential
  subscribers live out of reach of DSL
• Combined delivery of high quality voice AND
  high-speed data are key to success
• Voice alone is not enough operators need to
  offer high speed data in order to remain
  competitive
• Data alone can rarely generate sufficient
  revenues to justify the business case for ANY
  technology
• High Churn rates
• Some markets churn at 2 percent per month

5
Technology trends to address market needs

• Data speeds
• Wireless DSL systems available today to meet data
  speed requirements
• Many technical developments underway to achieve
  future data needs
• 64QAM MIMO OFDM multi-carrier CDMA etc
• Distance independence from exchange
• Frequency band is critical to achieving good
  range LMDS is not appropriate for residential
  market
• Below 5GHz is best compromise
• Wireless DSL systems deliver!
• Combined delivery of high quality voice AND
  high-speed data
• VoIP to end customer is not the best solution for
  residential
• But integration with VoIP networks is a clear
  industry trend
• High churn rates
• Need to be able to recover large proportion of
  installed equipment when subscriber churns away
  Integrated external subscriber equipment
• Very short installation/recovery time auto
  configuration of subs equipment, subscriber
  installs

Technical and Technology Aspects

Technology Evolution for low-cost BWA
Flexible, scaleable Base Station (CT) architecture
Modular CTs for Microcell applications and
small-scale deployments
Infrastructure
Wide range of voice and data terminals

• Expanded range of terminals
• Lower cost
• Multi-Megabit Speeds

CPE
ASIC technology

• Soft-configuration
• Higher integration
• Smaller footprint
• Higher Bandwidth
• Higher spectral efficiency

CPE - Airspans approach

• Internal Service Dependent unit
• Upgradeable / replaceable if service mix changes
• Low power
• Unobtrusive

• External Frequency dependent antenna
• Small, lightweight, easy to deploy
• Single co-ax connection

This approach maximizes flexibility whilst
minimizing product cost
9
Lower costs through standardization

• Agreement on standards can make a significant
  impact on technology costs - viz the
  (GSM/cdmaOne) mobile markets.
• However in the broadband wireless access market,
  the needs are different
• Non-uniform regulation and allocation of spectrum
• Customers are not mobile
• Much proprietary development has been undertaken
  already
• Some fora are active
• IEEE 802.16 (WirelessMAN) - Widest industry
  support today
• WDSL Consortium
• ETSI BRAN/HyperAccess
• . Others
• Standards may evolve - but not before many
  systems have been deployed!

10
System range and performance

• This is key to the ultimate economics of a given
  system
• 5 x range will typically need 25 x fewer base
  stations to cover given area
• There are also 25 fewer backhaul links to be
  installed
• HOWEVER this depends on having sufficient system
  capacity for large range systems
• AND sufficient spectrum
• Where many small sites are deployed,
  INTERFERENCE is often the limiting factor
• In comparing the economics of various systems, it
  is essential to examine the detailed tradeoffs
  between
• Capacity
• Deployed spectral efficiency
• Associated costs of (e.g. backhaul, site
  acquisition, power)

11
Quality and DFM (Design For Manufacture)

• Operational costs are in many cases highly
  dependent on the maturity of the product, the
  quality of the build and the experience of the
  manufacturer concerned
• Operating BWA equipment requires
• Extremely rugged tried-and-tested designs capable
  of withstanding a wide range of climatic
  conditions
• A product that can be easily maintained or
  upgraded, with minimal downtime while upgrades
  are undertaken
• Comprehensive OM facilities
• To manufacture such high performance equipment
  requires excellent DFM techniques, and access to
  high-volume production lines in order to achieve
  lowest-cost product.

12
System Architecture

• Frequency
• Many different frequency bands and allocations in
  many different global markets
• No world-wide frequency standards
• Inevitable consequence an architecture that
  restricts frequency flexibility will not achieve
  ultimate low-cost - insufficient manufacturing
  volumes
• Services
• Wide variations in service requirements and mix
• Mixtures of 10bT, n x POTS, leased lines, ISDN
• Combinations of service delivery to customers
  such as voice and data
• Dictates need for flexible subscriber service
  delivery unit
• HOWEVER - more modularity generally leads to
  higher costs therefore careful design that
  achieves both flexibility and low-cost needs to
  be thought through from the outset.

• More equipment can be recovered when subscribers
  churn

15
OM - key requirements

• Fault detection and repair
• Presentation of events
• Redundancy - automatic/manual switching
• Routine/background testing
• Over the air customer activation
• Minimal turn-up cost
• Links into other management systems
• Service management
• Performance analysis
• Quality of service
• Minimize cost and frequency of customer call out

  team per day
• Low installation costs

18
Radio survey

• Note trees all around! Systems need to work
  reliably in this environment!
• Results used to predict which subscribers can be
  reached targeted deployment at lowest
  operational cost

19
Infrastructure

• Modularity to achieve scalability and
  customisation
• Re-use of hardware as multi-function boards
  soft-configured for different functions
• Reduces costs
• Simplifies spares
• Simplifies maintenance
• Minimal requirement for site visits
• Full configuration and upgrade via OM
