Wireless is getting harderWiMAX is the tipping
point for many of these trends
while standards are changing faster than ever
Wireless gets harder, faster than Moores Law
markets are fragmenting further
And competition is increasing, globally

Rationalisation2003Savage emphasis on focus,
increasing outsourcing/partnership, cutting

smart sourcing, partnerships Rising importance of
subsystems modules (eg OBSAI)

WiMAX has a portfolio of applications,
competitors

• The good thing about WiMAX is it can do many
  things
• WiMAX faces various competitive technologies
• But need to be BETTER than the others at ALL
  those things
• Requires seamless coverage
• Requires indoor coverage
• Requires high data rates

Compete with DSL
Compete with 3G
Compete with WiFi

therefore need portfolio of basestations

Laws Of Physics, Laws of Economics

• Small cells work better than big ones
• 2.5GHz does not go well through walls
• 64QAM does not go well through walls
• Most people use services indoors
• 60 of cellphone calls
• 100 of datause
• If your business case relies on high-data rates
  indoors
• But subscribers do not get high data rates
  indoors
• Then what do you do?

17
Show Me The Money !

• If copper exists, then Wireless will ALWAYS cost
  more than wired
• Therefore, WiMAX must win on ubiquiity

18
Laws Of Physics

• Shannons Law
• Only ways to get more bps/Hz
• Increase power
• Smaller cells
• Add smarts (MIMO, MAS)
• If WiMAX is to deliver, we need to plan for these
  in network

19
The logic expressed in dB and SINR

• In-building coverage is critical
• 70 of use is indoors Higher for data
• Building loss (especially with metalized windows)
• Serving in-building from outside is like trying
  to fill a cup from a firehouse outside, spraying
  wildly
• Improves both in-building and outside CIR
• DAS or repeaters improve coverage but not
  capacity or data rate

20
The logic expressed in and RoI
21
Shannon, Isenberg Cooper

• Shannons Law
• There is a limit to capacity
• and we are getting close to it
• Best way to increase capacity is shrink cells
• Shorter range, improves C/I
• Improves capacity quality

• Isenberg
• The rise of the stupid network
• Push intelligence out to the edge

• Coopers Law
• Capacity of wireless has doubled every 30 months
  for the past 105 years.
• The gains come from a range of sources, but most
  significant is the reuse of frequencies in
  smaller and smaller cells.

Since 1950 wireless capacity has increased 1
million fold the primary factor in this is the
move to many, smaller, cells

picoCells

• OUTDOOR
• Outdoor extended outdoor coverage
• Railway station, airport, shopping center, hot
  spots, blind zones, street coverage
• Network densification, and service improvement
• Reduce number of macro cells
• Backhaul with Metro-Ethernet, xDSL, MW links,

• INDOOR
• Hot-spot
• Airport, Hotel, shops
• Corporate Enterprise
• Complements WiFi
• Backhaul with Ethernet or DSL
• Must meet cosmetic operational deployment

-Decrease the number macro cell needed for a
given area -Improve service availability (esp. In
difficult areas) -Allow densification in hot
spots -Decrease overall power needed (Health
regulatory constraints) -Lower visual impact
(easier installation, no macro site needed)

27
Femtocells Background

• Wireless market saturated
• Operators need new strategies to drive ARPU and
  gain customers
• Threats
• New entrants (MVNO, Voice-over-WiFi)
• Churn subscriber acquisition cost
• Strong desire to shift users to 3G
• Better cost structure / usage of spectrum
• Competitive differentiation
• Higher ARPU from new services
• Demonstrate to shareholders that buying licences
  made sense
• But 3G coverage is lousy indoors (especially for
  data)
• Femtocells allow Wireless operators to
  (profitably) compete with voice-over-WiFi

• Threat from voice-over-WiFi eg BT Fusion
• Idea mainstream in 3G operators
• RFQs issued

Cellular Carrier
OptionalWiFi integrated

• Enables cellular carriers to compete with VoIP,
  WiFi and UMA (eg Fusion)
• 3G BS feels like WiFi AP
• Very aggressive price targets (ltlt200)
• 4 users, 50-200m
• No need for expensive dual-mode handsets
• All the benefits of FMC for a cellular carrier

29
Home Basestation

• Benefits to Consumer
• Reduces cost (free calls!)
• Improves coverage no deadspots
• Simplicity single Device, all numbers in one
  place
• No need for expensive new device

• Benefits to Operator
• FEAR
• Counters threat from VoIP UMA
• GREED
• Increases both coverage and capacity
• Reduces churn
• Increases ARPU (sell BB too)
• Works with all existing handsets no need for
  expensive subsidies on dual-mode
• Increases 3G adoption

Concluisions

• If WiMAX is to succeed, it must deliver on
  customers expectations
• Seamless access
• Good data rates
• Indoor coverage
• Laws of physics you cannot do this with
  macrocells alone
• Require a portfolio
• Must include picocells femtocells
• These are NOT just macrocell with smaller PA
