2 agenda wireless web primer development tidbits future

3 Wireless Web Primer Overview Wireless Solution Devices Wireless Networks Middleware Applications Wireless Web solutions require four key components

4 Wireless Networks Its All About Standards and Speed

5 Wireless Networks Evolution 1G analogdigital circuit-switched networks connection is persistent (requires a dedicated path for the duration of the connection) Voice AMPS AMPS = Advanced Mobile Phone System a cell is subdivided by frequency into distinct channels, which allows multiple access to cells; the service can assign only one subscriber at a time to each channel within a cell

6 Wireless Networks Evolution 1G analogdigital circuit-switched networks connection is persistent Voice AMPS AMPS = Advanced Mobile Phone System a cell is subdivided by frequency into distinct channels, which allows multiple access to cells; the service can assign only one subscriber at a time to each channel within a cell challenges user demand exceeded available bandwidth voice only - no data solutions allow multiple access -- i.e. more users per channel and frequency begin convergence of media types leads us to 2G

7 Wireless Networks Evolution 2G TDMA Time Division Multiple Access message origin message destination time slot 1 =I love beer time slot 2 = How are you? time slot 3 = Call me back I How Call love are me beer you back Messages reassembled by original timeslots 3 separate user messages carried over same channel sidebar wireless network standards: TDMA and CDMA move to multiple access still circuit-switched

8 Wireless Networks Evolution 2G sidebar CDMA Code Division Multiple Access message origin wireless network standards: TDMA and CDMA code A5 =I love beer code B2 = How are you? code X7 = Call me back I How Call love are me beer you back A5 B2 X7 A5 B2 X7 A5 B2 X7 up to 6 separate user messages carried over same channel Fact: 2G CDMA can provide approximately 10 to 20 times the capacity of analog AMPS and four to six times the capacity of TDMA message destination Messages reassembled by original assigned codes move to multiple access still circuit-switched

9 IS-95 cdmaOne GSM Wireless Networks Evolution kbps kbps CDPD DataTAC Mobitex 19.2 kbps dedicated data networks (no voice) IS-136 TDMA CDMA 2G CDPD =Cellular Digital Packet Data GSM =Global System for Mobile Comm. CDMA = Code Division Multiple Access TDMA = Time Division Multiple Access Voice AMPS move to multiple access still circuit-switched analog digital

10 move to multiple access still circuit-switched IS-95 cdmaOne GSM Wireless Networks Evolution kbps kbps CDPD DataTAC Mobitex 19.2 kbps dedicated data networks (no voice) IS-136 TDMACDMA 2G CDPD =Cellular Digital Packet Data GSM =Global System for Mobile Comm. CDMA = Code Division Multiple Access TDMA = Time Division Multiple Access analogdigital Voice AMPS challenges multimedia data content of the wireless web (i.e. graphics, video) requires much greater bandwidth latency issues associated with dial-up solutions expand data capacity of wireless networks move to packet-switched (IP-based) network leads us to 2.5 and 3 + G

11 Wireless Networks Evolution Voice AMPS 384 kbps GPRS EDGE EDGE = Enhanced Data Rates for GSM Evolution GPRS = General Packet Radio Service 2.5G move from dial-up circuit- switched data to always on packet-switched data 1xRTT 1xEV IS-95 cdmaOne GSM kbps kbps CDPD DataTAC Mobitex 19.2 kbps dedicated data networks (no voice) IS kbps144+ kbps TDMACDMA IS-136+ GPRS-136 analog digital

12 Wireless Networks Evolution 3+G3+G high-speed data services to support multimedia applications Voice W-CDMA = Wideband CDMA UMTS= Universal Mobile Telecommunications System IMT-2000= International Mobile Telecommunications in the year 2000 (IMT-2000) TDMACDMA W-CDMA UMTS IMT-2000 cdma 2000 IMT kbps GPRS EDGE 1xRTT 1xEV IS-95 cdmaOne GSM kbps kbps CDPD DataTAC Mobitex 19.2 kbps dedicated data networks (no voice) IS kbps 144 kbps (up to 5 mbps) AMPS IS-136+ GPRS mbps analog digital

14 Wireless Networks Flavours Terrestrial National / Regional / Urban areas GSM - Microcell (Fido) CDMA - Bell Mobility, TELUS Mobility, Verizon TDMA IS Rogers AT&T, AT&T Wireless GPRS - Microcell (Fido), Rogers AT&T W-CDMA (using iMode) - AT&T Wireless CDPD - Bell Mobility, TELUS Mobility, Verizon Mobitex - Rogers AT&T, Cingular DataTAC (ARDIS) - Motient Ricochet - Metricom (US cities) SMS (various) Paging (various)

15 Wireless Networks Flavours Satellite: Rural areas e.g. Iridium, GlobalStar, Teledesic Wireless LANs: Campus e.g. UBC, Microsoft Your Home Wi-Fi (802.11b) Very short-range Bluetooth, Infrared wireless mouse, ID badges, etc. Terrestrial National / Regional / Urban areas

16 Devices Wireless Networks Where are We?

17 Devices Through at least 2003, 35% of knowledge workers will rely on a mix of three or more devices during the business day (e.g. laptop, phone & PDA) - Gartner Group

18 Phones Types WebPhones (browser-only) - old school WAP phones - 2G SmartPhones (PIM functionality) Tri-Mode GPRS Phones Motorola P280 and Motorola v66 Tri-mode i.e. operates at 800, 900, 1900 MHz meaning what? You can use this same phone in South America, North America, Europe, Asia, Africa, Oceania What can these phones do? 2-way text messaging (like RIM), predictive text input charged by data volume, not airtime used - always on (like RIM) PIM (calendaring, contacts - like Palm) voice-activated dialing games, currency conversion, etc etc

19 Handheld Devices Examples Palm O/S Handspring Visor Sony Clie Palm Pocket PC O/S Compaq iPAQ HP, Casio RIM O/S RIM Handhelds Types PDAs Pagers

20 Wireless Modems AirBoard PDA Adapters AirCard Type 2 PC Cards Embedded Modules Vehicle Mounted Rugged Mobiles

21 Wireless Modems AirCard 300 – CDPD –19.2 Kbps* –Flat rate pricing – always on AirCard 510 – CDMA –14.4 Kbps *kilobytes per second Sierra Wireless AirCards for Laptops

22 Devices Wireless Networks Applications Where are We?

23 Applications The Search for the Next Killer App

24 Wireless Internet Killer App Criteria Immediate, spontaneous access Take advantage of niche time Personalized Timeliness of information Location-based Presence or context based Pricewaterhouse Coopers Right Information, Right Place, Right Time

25 Business Applications Supply Chain Execution** Shipment tracking and stock-level monitoring Scheduling and Dispatch** Database Inquiry** License Registration Location Monitoring Truck tracking - GPS Fixed Telemetry** Remote device monitoring and control (e.g. meter reading and remote diagnostics) Wireless eCommerce Business & Government Right Information, Right Place, Right Time ** Noted as one of the most important wireless application markets [IBM research]

26 Consumer Applications Consumer Account-based Transactions** e.g. Stock Quotes, Banking, Member ticket purchases, travel itinerary mods PIM Services** e.g. Instant Messaging Organizer Synching Location based e.g. Restaurants, Movies, Commerce….coupons, tracking (kids, pets) Entertainment e.g. Games Automobile platforms** e.g. navigation and safety GMs OnStar service Right Information, Right Place, Right Time ** Noted as one of the most important wireless application markets [IBM research]

27 Applications Business Consumer Individuals can belong to both groups Creates new opportunities and challenges - Voice-enabled devices Our research is conclusive. More people can talk than type. [President, Sprint] - Billing & Security - Intellectual Property carriers new value as distributors (like television)

37 Things to Know Terminology Web site = Deck data loads into device one deck at a time (limit due to memory constraints to 3 Kb) Web page = Card

38 Things to Know Terminology Web site = Deck data loads into device one deck at a time (limit due to memory constraints to 3 Kb) Web page = Card Duplication, maintenance 2 site versions? Right. On-the-fly tag conversion (www.clearigo.com - middleware) based on device / browser type

39 Things to Know Design based on device form factors: screen real estate user input interface (numeric keys, touch screen, voice and handwriting recognition) Battery life Memory / storage capabilities

40 Things to Know Design based on device form factors: screen real estate user input interface (numeric keys, touch screen, voice and handwriting recognition) Battery life Memory / storage capabilities Cellular Coverage Offline processing and storage requirements (memory & battery limits) Data synchronization
