But not guaranteed successBut not guaranteed success

• “Gold standard” for performance is wired (dialup or LAN) connection

• Service providers, ASP’s, application and content providers will focus on the moderate-to-high bandwidth customers

• Pricing of wireless must be competitive with wireline alternatives

Requirements for realizing the opportunityRequirements 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

Requirements for realizing the opportunity (cont’d)Requirements for realizing the opportunity (cont’d)

• Low barriers to entry for service and content providers– cost … complexity

• Low barriers to entry for access operators– cost … complexity

Traditional cellular systemsTraditional 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

Fixed Wireless Access systems (MMDS, …)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)

• Only moderate spectral efficiency, and limited capacity below 3 GHz

• Best suited as “local loop bypass” solutions

Central elements of the “right” solution 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)

• PPP connectivity model– leverages existing ISP

provisioning, management and billing tools

– PPP sessions backhauled via L2TP

Open Service Features (cont’d)Open Service Features (cont’d)

• Clear separation of access and end-user service– shared access and

transport network– connectivity to multiple

ISP’s, ASP’s, content and VPN providers

Radio Access PlatformRadio 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 >1 Mbps• PC Card, USB, Ethernet end-user devices

Radio Access Platform (cont’d)Radio Access Platform (cont’d)

• “Smart” antennas using spatial processing maximize capacity and coverage

Radio Access FeaturesRadio 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
