Wireless Networks It’s All About Standards and Speed
Wireless Networks Evolution 1G analog digital circuit-switched networks connection is persistent (requires a dedicated path for the duration of the connection) AMPS Voice 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
Wireless Networks Evolution 1G analog digital circuit-switched networks connection is persistent • 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 AMPS Voice 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
Wireless Networks Evolution 2G sidebar wireless network standards: TDMA and CDMA move to multiple access still circuit-switched Messages reassembled by original timeslots time slot 1 =“I love beer” message destination time slot 2 = “How are you?” TDMA message origin time slot 3 = “Call me back” Time Division Multiple Access 3 separate user messages carried over same channel I How Call love are me beer you back 1 2 3 1 2 3 1 2 3

CDMA = Code Division Multiple Access TDMA = Time Division Multiple Access CDMA TDMA
Wireless Networks Evolution 2G • 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 analog digital move to multiple access still circuit-switched AMPS dedicated data networks (no voice) Voice IS-95 cdmaOne GSM IS-136 CDPD DataTAC Mobitex 19.2 kbps 14.4 - 33 kbps 14.4 - 58 kbps CDPD =Cellular Digital Packet Data GSM =Global System for Mobile Comm.

Wireless Networks Evolution 3+G high-speed data services to support multimedia applications analog • current challenges • device manufacturers need to develop network compatible products • wireless spectrum auctions were a huge money grab for governments, left little money left for carriers to actually build & deploy networks • BUT capital markets have dried up for telecom market -- for carriers and manufacturers alike • 3G and beyond will likely not be achieved before 2005, and some are now speculating 2007 digital W-CDMA CDMA 2000 AMPS 1xRTT 1xEV GPRS EDGE Voice dedicated data networks (no voice) 384 kbps CDPD DataTAC Mobitex IS-95 cdmaOne GSM IS-136 D-AMPS 19.2 kbps 14.4 - 33 kbps 14.4 - 58 kbps W-CDMA = Wideband CDMA TDMA CDMA

Wireless Networks Devices Where are We?
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
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
