Wireless Web Primer Overview

Middleware Applications

Wireless Web solutions require four key components

WirelessNetworks

It’s All About Standards and Speed

Wireless Networks

Evolution

1Ganalog digital 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

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

Fact: 2G CDMA can provide approximately 10 to 20 times the capacity of analog AMPS and four to six times the capacity of TDMA

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

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

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

PhonesTypes• 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, OceaniaWhat 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

Handheld Devices

ExamplesPalm O/S• Handspring Visor• Sony Clie• PalmPocket PC O/S• Compaq iPAQ• HP, CasioRIM O/S• RIM Handhelds
