This document discusses the challenges of wireless enterprise applications. It outlines some of the key challenges including lack of interoperability between devices, competing network standards, coverage issues, and security concerns. It then discusses specific challenges around management of devices, networks, and platforms. Under networks, it outlines current and future network standards. For devices, it profiles some popular devices like BlackBerry, Pocket PC, and Palm OS devices. It proposes a development and delivery architecture to address these challenges using email as a common denominator and providing an evolutionary approach.

delivery platform

7. Challenges - Networks

8. Today’s Networks
• GSM – Europe’s current wireless standard
• iMode – DoCoMo technology
• CDPD – AT&T data service
• Mobitex & DataTac
• Other networks
– Metricom
• Wireless LANs
– 802.11b

9. Tomorrow’s Networks
• 2.5G
– GPRS
– 1XRTT
– EDGE
• 3G (3rd
generation) high speed, packet switched
– UMTS
– HDR
– EDGE
• Wireless LANs
– 802.11a
– Bluetooth

10. Challenges - Devices

11. Devices – RIM 950/850, 957/857
• “Always on” wireless data device
• Low power 386 chip
• Storage up to 5 MB
• Works over Mobitex, DataTac, GPRS
• Runs BlackBerry Email service

12. Devices – Pocket PC
• Lots of different chips
– Up to 206 MHz
• Storage up to 64 MB
• Wireless requires a full-size card (e.g., Sierra
Wireless)
• Most robust platform for development

13. Devices - Palm
• Defined the market
• Lots of software
• Motorola Dragonball chip up to 20 MHz
• Wireless through Omnisky
• Memory up to 8 MB (or memory stick)

14. Devices - Other
• PC variants (palmtops, laptops)
• Smartphones
• Pagers
• Tablet

15. Challenges - Platform

16. Current Approach
Extend the web paradigm via transcoding techniques.
On-line Paradigm Assumes
• Existing content can simply be
“Ported”
• A fat pipe exists
• Network is always there
• All desk top information is
appropriate on a small device
• People are patient

17. Current Market Approach Fails
• Only need to present
relevant data
• 19.2kbs is prevalent
• Must find ways to “speed” up
development and delivery
• Networks Unreliable
• Mobile Applications
• Broadband networks are in
the distant future
• Must use a framework
• Off-line capabilities and synching

18. Development and Delivery Architecture

19. A migration path
 An architecture for today and tomorrow
 While geared to J2ME devices, it
 Recognizes investment made in existing technologies and devices
 Uses email as the least common denominator
 Benefits
 Common architecture for the long run
 Enables an evolutionary approach that acknowledges that change is
constant….Business Processes, Technology, Devices
