But not guaranteed success

• Gold standard for performance is wired (dialup
  or LAN) connection
• Service providers, ASPs, application and content
  providers will focus on the moderate-to-high
  bandwidth customers
• Pricing of wireless must be competitive with
  wireline alternatives

4
Requirements for realizing the opportunity

• The best aspects of wired connections
• reliability per-user throughput low cost
  rich content
• The best aspects of wireless connections
• freedom to move always on ubiquity

5
Requirements for realizing the opportunity
(contd)

• Low barriers to entry for service and content
  providers
• cost complexity
• Low barriers to entry for access operators
• cost complexity

6
Traditional cellular systems

• Provide a partial solution
• ubiquity and high-speed mobility
• But ...
• designed to support low bandwidth, intermittent
  subscribers
• can not provide significant per-user throughput
  at low cost
• expensive and complex networks
• Best suited to high mobility, low bandwidth
  applications with specialized content

7
Fixed Wireless Access systems (MMDS, )

• Meets a different set of the requirements
• ubiquity, moderate-high per user bandwidth,
  reliability
• But
• neither mobile nor portable
• typically require professional installation of
  end-user equipment (not low cost)

8
Fixed Wireless Access systems (MMDS, )

• Only moderate spectral efficiency, and limited
  capacity below 3 GHz
• Best suited as local loop bypass solutions

9
Central elements of the right solution

• Massive capacity to deliver high speed, high
  quality service to all customers
• Spectral efficiency to enable economical
  operation in crowded bands below 3 GHz
  (portability requirement)

10
Central elements of the right solution (contd)

• Mass market pricing
• Data-centric, open, IP architecture for content
  and services

• All of the above are achievable today

Open Service Features

• End to end IP connectivity for end-users
• widest choice of end-user terminals and
  applications
• common service and content base for wired and
  wireless users

13
Open Service Features (contd)

• PPP connectivity model
• leverages existing ISP provisioning, management
  and billing tools
• PPP sessions backhauled via L2TP

14
Open Service Features (contd)

• Clear separation of access and end-user service
• shared access and transport network
• connectivity to multiple ISPs, ASPs, content
  and VPN providers

15
Radio Access Platform

• Optimized air interface for reliable and
  efficient packet data transport
• Time Division Duplexed (TDD)
• maximizes flexibility in band selection (key
  below 3 GHz)
• maximizes flexibility in accommodating asymmetry
• Peak per-user data rates gt1 Mbps
• PC Card, USB, Ethernet end-user devices

16
Radio Access Platform (contd)

• Smart antennas using spatial processing
  maximize capacity and coverage

17
Radio Access Features

• Spatial processing TDD
• maximizes flexibility in band selection
• provides unmatched coverage and spectral
  efficiency, 4 b/s/Hz or 40 Mbps/cell in 10 MHz
• Native IP interface to wired network
• simplifies network architecture
• allows operator broadest choice in wired network
  elements
• reduces network cost

18
Keys to Delivering Portable Broadband Multimedia
Access

• Massive Capacity Enabling High Speed,
  High-Quality Service for ALL
• Adaptive antenna technology (spectral efficiency)
• Ubiquitous Coverage Mass Market Pricing
• Internet/Open Architecture for Content and
  Services

19
Wireless DSL System Features

• 4 Bits/Sec./Hz/cell Spectral Efficiency Provides
  400x capacity over 2G and 40x over 3G
• 1 Mbps to 40 Mbps User Data Rates
• Powered by IntelliCell Adaptive Smart Antenna
  Processing with Packet Switching
• End to End Wireless IP Access and Transport
• TDMA/TDD Packet Air Interface
• Licensed Spectrum Below 3 GHz

Summary

• The potential market is huge
• Successful solutions have to address all of the
  markets needs
• the performance of the wired network
• the applications of the wired network (the
  availability of the wireless link will foster new
  apps)
• the freedom of wireless
• The challenge can be met with proven technologies
  in a Wireless DSL architecture
