3. Copyright © 2003 Slide 3 Wireless Technologies: It’s Not All “Wi-Fi” “Wi-Fi” literally means conformance to IEEE 802.11 WLAN specifications Widely misused to mean any kind of wireless networking LAN MANWAN PAN “Wi-Fi”

5. Copyright © 2003 Slide 5 ~Early 2001 Wireless networking – 2 Mbps in 2.4 Ghz -HomeRF -802.11 Fixed Wireless -Licensed bands -Proprietary technologies -Line of sight (LOS) -Outside antenna -Truck roll installation Sprint -MMDS -Hybrid technology

6. Copyright © 2003 Slide 6 2003 Wi-Fi (802.11) b 11 Mbps in 2.4 GHz a 54 Mbps in 5 GHz g 54 Mbps in 2.4 GHz “Fixed” Wireless -Licensed / unlicensed -Many technologies -Proprietary => 802.16 standards -LOS/Non-LOS -Antenna outside/inside -Truck roll / self-install -Many service providers -XtraTyme (unlic.) -Clearwire (licensed) “Community Networks” –Bay Area Research Wireless Network “Broadband Anywhere” -3G rolling out (slowly) -New technologies for ubiquitous broadband wireless -Proprietary => 802.20 standards -ArrayComm -IP Wireless “Hot spots” and “hot zones” -Intel -T-Mobile -Boingo

7. Copyright © 2003 Slide 7 Two Approaches for “Broadband Anywhere” “Inside out” –Start with LAN technology and extend its reach as far as possible –“Hot spots” and “hot zones” –“Neighborhood area networks” –“Mesh networks” “Outside in” –Start with MAN technology and make it powerful enough to reach inside buildings through trees and walls Not “either / or” –Both approaches will play a role

8. Copyright © 2003 Slide 8 Some Questions… Where does Wi-Fi make sense – and where not? What role does “fixed” broadband wireless play? Can wireless compete with wireline for BB access to the cloud in densely populated areas? How important are ITU and IEEE (802.11,.16,.20) standards? What role will “3G” play? How will the hot spot business shake out?
