OutlineOutline• Main themes

• Broadband wireless – Residential market characteristics and trends

• Technology trends to address market needs

• Airspan’s response

• Conclusion


Main themesMain 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


Residential market characteristics and trendsResidential 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


Technology trends to address market needsTechnology 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

CPE - Airspan’s approachCPE - Airspan’s 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


Lower costs through standardizationLower 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!


System range and performanceSystem 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)


Quality and DFM (Design For Manufacture)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 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.


System ArchitectureSystem 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.

• 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


O&M - key requirementsO&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

• Simple, fast install: typically 10 STs per 2-man team per day• Low installation costs


Radio surveyRadio 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


InfrastructureInfrastructure• 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

• Low-cost solutions are available for residential markets – especially SoHo applications

• Application of new technology is driving costs down:– Quicker install, HomeRF/PNA, and self-install– Product costs

• Delivery of bundled services (voice and data) produces a compelling business case for ILECs, CLECs and ISPs
