How Do Service Provider’s Differentiate?
• Differentiated services
• Reliable service offerings
• Competitive Pricing
• Service management
As a wireless technology, WiMAX imposes new challenges
4
WiMAX deployment models are shifting
• Carriers’ business plans are evolving
– First-generation WiMAX enables fixed BWA
• Optional WiMAX features provide differentiation
– Advanced WiMAX features will enable indoor self-install model
– 802.16e will bring portable/nomadic and mobile capabilities:
Personal Broadband
• Deployment models will vary at different stages of
WiMAX evolution

Differentiated Services
• Premium offerings
– High-bandwidth services
– Guaranteed QOS
• Full suite of IP services
• VoIP: Tiered service offerings possible
– Basic (VoIP services available over any high-speed connection)
– Carrier-class VoIP (Primary-line voice for residential/SOHO)
– Enterprise (connections to IP PBX, IADs or hosted IP Centrex)
• Service Bundling
• Nomadic services: Personal Broadband
Advanced scheduling services and QOS management required
“Basic” WiMAX is not sufficient

Reliable Service Offerings
• Reliable services are built on reliable networks
• User Internet experience must be consistent
• High-availability NLOS wireless connections critical
–

–
Licensed spectrum required
Optional WiMAX airlink features are critical
Reduce customer support and complaint calls
Installation and service verification tools important
Build reputation for reliability
• Minimize time required to solve customer problems
– Rich, real-time diagnostic tools important
– Service “health check” and efficient problem resolution
10
Performance Monitoring Capabilities
• 24x7 Monitoring of the Performance of the Network
– WAN Interface Performance
– Airlink Performance

Packet data
Voice
Block error rate
RSSI, C/I, K-factor (at CPE)
Dynamic channel allocation
Power control
– Call Processing Performance
– Network Interface Performance
• Operator benefits from deep visibility, debug and control
Reports showing trends in performance allow
the operator to fine-tune operating procedures
11
Competitive Pricing
• Service pricing influenced by cost of network build out
• Minimize up-front Capex
– “Pay-as-you-grow” model
– WiMAX equipment must be selected to reduce overall network
cost
– Optimize use of spectrum and equipment
• Minimize Opex
– Reduce costs associated with unsuccessful installs
– High-availability connections reduce customer support and
complaint calls
– Minimize time required to solve customer problems
Expenses associated with a network can be a bigger driver than capital
cost in your business model. WiMAX solutions must place an emphasis on
those expenses and use technology to keep them under control.
12
Service management
• Rapid service activation important
–

–
High predictability of wireless coverage essential.
Network design with probability of coverage in mind
Optional WiMAX airlink features are critical.
Reduce installation time and unsuccessful installs
• Integrated tools to ease service provisioning
• Hosted IP services add additional flexibility
• WiMAX model evolving to include external policy servers
– Dynamic service provisioning
– WiMAX equipment must be capable of maintaining QOS in this
environment
13
WiMAX deployment model #1
• Pay as you grow
• Start with a few macro-cells per city
– Traditional model for BWA networks
– Minimize initial investment
• Outdoor-install CPEs required to achieve desired coverage
– Advanced optional WiMAX features required to provide desired
coverage and maximize link availability under NLOS
• Indoor self-install possible for close-in CPEs
– Advanced optional WiMAX features become critical
• Increase network capacity as subscriber base grows
– Additional base stations and/or sectors per BS

Macro-cell Example using pre-WiMAX symmetry

WiMAX deployment model # 2
• Start with many micro-cells per city
–

–
–
Traditional model for mobile networks
Maximize network capacity and coverage
Larger initial investment required
Network designed to maximize probability of coverage
• Higher percentage of indoor self-installs possible
– Advanced optional WiMAX features become critical
• Near-ubiquitous coverage enables nomadic services:
“Personal Broadband”
16
Maximizing probability of coverage
Blue areas represent
90% probability of coverage.

WiMAX Network Deployments?
• WiMAX-deployments need WiMAX-certified equipment
– Will start for real in 2006
• Carriers have been moving forward nevertheless
– Deploying WiMAX-ready technology where upgrade path to
WiMAX-certified exists
– Technology trials to understand WiMAX technology
– Development of business plans
– Spectrum acquisition
– Vendor selection
