Wireless is getting harder WiMAX 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

Historic Vertically Integrated or Captive Eg
ATT-ATT Networks BT-Plessey FT-Alcatel
Break-up 1990 Move to Layering and open
sourcing, but OEMs still essentially
integrated Eg AT-T Lucent (which includes Lucent
Semiconductors)
The Bubble 1999 Explosion of operators, OEMs
suppliers Increasing emphasis on focus sourcing
Rationalisation 2003 Savage emphasis on focus,
increasing outsourcing/partnership, cutting
costs OEMs largely buy-in all components (Agere,
Freescale)
Maturation 2007 Emphasis on increasing value,
smart sourcing, partnerships Rising importance of
subsystems modules (eg OBSAI)

10
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
11
… therefore need portfolio of basestations

  • Conclusions

16
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

23
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)

  • WiMAX
  • Conclusions

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

28
Femtocell Becoming Mainstream within 3G
Home network (50m-200m) 4 users
7Mbps HSDPA
Broadband
DSL
Cellular Carrier
Optional WiFi 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

30
3G this is reality Powered by picoChip
  • picoChip defined femtocell concept
  • First demo 3GSM 2005
  • Silicon software shipping now
  • Complete reference design compliant
    interoperable
  • HSDPA now, software upgrade to HSUPA
  • Roadmap to HSPA (MIMO) and LTE
  • Also for GSM/EDGE, WiMAX cdma2000/EVDO

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
