  1. Broadband Wireless World Forum San Francisco – February 2001 www.airspan.com Unlocking the Broadband Residential Market – Advances in Low-Cost CPE and Installation Eric Stonestrom CEO

  2. Outline • Main themes • Broadband wireless – Residential market characteristics and trends • Technology trends to address market needs • Airspan’s response • Conclusion BWWF Feb 2001 - (c) Airspan Networks Inc

  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 BWWF Feb 2001 - (c) Airspan Networks Inc

  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 BWWF Feb 2001 - (c) Airspan Networks Inc

  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: Integratedexternal subscriber equipment • Very short installation/recovery time: auto configuration of subs equipment, subscriber installs BWWF Feb 2001 - (c) Airspan Networks Inc

  6. Technical and Technology Aspects

  7. 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 Underlying Technology TIME Speed Cost BWWF Feb 2001 - (c) Airspan Networks Inc

  8. 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 CPE - Airspan’s approach This approach maximizes flexibility whilst minimizing product cost BWWF Feb 2001 - (c) Airspan Networks Inc

  9. 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! Lower costs through standardization BWWF Feb 2001 - (c) Airspan Networks Inc

  10. 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) System range and performance BWWF Feb 2001 - (c) Airspan Networks Inc

  11. 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 O&M 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. Quality and DFM (Design For Manufacture) BWWF Feb 2001 - (c) Airspan Networks Inc

  12. 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.

  14. Home PNA and HomeRF allow simple and fast installation of CPE Customers may extend home networks more easily More equipment can be recovered when subscribers churn HomeRF and HomePNA Integrated Subscriber Terminal Phone1 RJ11 Home Wiring Phone2 ST-P1V2 Connect Box Power Supply BWWF Feb 2001 - (c) Airspan Networks Inc

  15. O&M - 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 • Evolve with the operator BWWF Feb 2001 - (c) Airspan Networks Inc

  17. Typical residential installation • Simple, fast install: typically 10 STs per 2-man team per day • Low installation costs BWWF Feb 2001 - (c) Airspan Networks Inc

  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 BWWF Feb 2001 - (c) Airspan Networks Inc

  19. 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 O&M Infrastructure BWWF Feb 2001 - (c) Airspan Networks Inc
