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

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
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

CPE - 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
BWWF Feb 2001 - (c) Airspan Networks Inc
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!
BWWF Feb 2001 - (c) Airspan Networks Inc
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)

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.
BWWF Feb 2001 - (c) Airspan Networks Inc
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.

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
