Solutions For Personal Broadband Deploying Now
• Wi-Fi Hotspot Bundles– SBC: DSL adder for $1.99– Dual Wi-Fi/cellular handsets from
SBC/Cingular for hand-off to hotspots and “roam to home”
• “Pre-WiMAX” Risk From 2.5 GHz band holders – Clearwire and Nextel already launched
• 3G: Verizon, Sprint • Municipal wireless using Wi-Fi
– Chaska, MN; Cerritos, CA; Philadelphia, PA; …
WiMAX – 802.16
• Broadband Wireless Access – Metropolitan Area Networks
• Fixed (and nomadic) access: 802.16-2004 (8/2004)
• Mobile access: 802.16e (expected 5/2005)
• Maximum cell size ~30 miles, 1.5 to 5 more typical
• Maximum speed 100 Mbps (64QAM/20 MHz)
WiMAX: Great Expectations
• Addresses deficiencies of previous BBW– Interoperability– Cost of base stations and CPE– Shared bandwidth up to 100 Mbps– Line of sight not required– Coverage 3-5 miles, more like cellular – Licensed and unlicensed spectrum
• Many DOCSIS-like features including QoS
• Milestone to “broadband everywhere”
WiMAX Bandwagon Effect
• WiMAX Forum: ~160 members and growing– Complete value chain– Many chip companies, including Intel, Fujitsu– Many major equipment companies, including
Motorola, Alcatel, Siemens– Many service providers, including BT, France
Telecom and Qwest
• Analogous to Wi-Fi Alliance for 802.11– Product certification through formal conformance
and interoperability testing against “profiles”– Promotion, promotion, promotion
WiMAX Status
• “Pre-certification” products shipping now– Based on earlier 802.16a standard– Expensive base stations and CPE – enterprise
focus
• Certified products in 2005– Based on 802.16-2004– Licensed 2.5 GHz (U.S.) and 3.5 GHz (ROW)– License-free 5.8 GHz– “Plugfest” interoperability testing started 2004– Formal certification testing ~1H05
• “Mobile WiMAX” expected late 2006– CPE bundled in laptops by 2007
Other Mobile Broadband Wireless Technologies Deploying Now
• FCC just restructured 2.5 GHz band from video to broadband service
• Band holders not waiting for WiMAX– Nextel running large-scale market trial
in Raleigh-Durham– Clearwire launched in Jacksonville, FL
and St. Cloud, MN– Sprint also owns spectrum, deferring
decision
Nextel in Raleigh-Durham
• Flarion “Flash-OFDM” technology
• Mobile within RDU area• Downlink 1.5 Mbps
(burst to 3Mbps)• Service starts at
$34.99 (750/200)• Combo Wi-Fi/Flarion
device: Netgear & D-Link
• Developing technical & market knowledge
Clearwire in Jacksonville, FL
•NextNet “pre-WiMAX” technology
•“Up to 1.5 Mbps”
•Starts at $24.99 (512/128)
•Easy self-install•Licenses in >80
markets
Metro Wi-Fi
• High-volume, low cost, low margin• Based on off-the-shelf consumer Wi-
Fi adapters• Not “carrier class” service• Disruptive to MSOs?
Wi-Fi Gaps Being Filled
• Issue– Spectrum usage– Security– QoS– Interference – Roaming performance– Throughput – Mesh techniques– Range– Connection
persistence
• Progress– 802.11a– 802.11i/WPA, WPA2– 802.11e/WMM– 802.11h, 802.11k– 802.11r– 802.11n– 802.11s
Specifics
City-wide “Hot Zones”
• Already deployed in some smaller cities• Big cities preparing to deploy soon• Public safety a major driver, “digital
divide” another• Near-term threat and opportunity for
MSOs
Rapid Pace of Innovation and Market Entry
• Mesh Networking– Tropos Networks– MeshNetworks– PacketHop– Nortel– Motorola– …
• Smart Antennas– Vivato– 5G Wireless– …
City-Wide Wi-Fi in Chaska, MN
• City operated, 16 square mile coverage area• Public safety, low-cost residential broadband service• 7500 homes passed, 1100 pre-registered• 200 cells, <$500,000 CapEx
Is Metro Wi-Fi Disruptive?
• “Disruptive Technologies”*– Simple, cheap– Target lower performance markets – Commercialized in emerging market– Fast technological progress
• Subsequently become performance competitive against established products
