Wireless Java Possibilities, Services, Limitations, and Competitors.Wireless Java

About this presentation l Show you what you can do with Java today, and tomorrow Overview of Wireless Java Why Java? Possibilities, limitations, and future expectations

What about wireless services?  Market penetration of mobile Internet expected to reach 25% within 4 years (Forrester)  Mobile Commerce in Europe alone is worth US $ 23 billion within 2003 (Durlacher) 

What is Wireless Java? l Java on the terminal – J2ME/MIDP l Server-side Java creating content for a terminal

Example of MIDP applications MasterMindJava Fly ByReport SheetSnake Screenshots from Sun’s Wireless Toolkit

What can MIDP do? l Standard programming tasks Calculations, threads, string handling, etc. l Display UI and handle input Low-level (control pixel drawing, input events) High-level (forms, fields, etc) l Store data l Simple network usage (http) l Limited functionality: Easy to learn Screenshot of Nokia’s Wireless Java SDK

Usage scenario: Enterprise Applications Mobilize your workforce!

Usage scenario: Games

Why Java on the Terminal? l Unique possibilities Offline usage Client-intensive computations Complex graphics and animations l Find and develop added value propositions

Why Java? Availability and platform independence l The promise of platform independence is suddenly extremely valuable l The promise of network deployment is suddenly even more valuable l JCP: Process controlled by handset manufacturers l Availability: 2 pieces of good news, one piece of bad Image copyright Sarah Brodwall

Good news: 25 million Java Phones!

Bad news: million of these in Asia

Good news: More are coming l Sun is estimating million Java phones by the end of 2002 l Vendors are announcing more Java phones in 2 nd half of 2002 l From forum.nokia.com: “Nokia alone intends to deliver tens of millions of terminals with Java technology by the end of the year (2002).”

New Phones (

MIDP 1.0 Limitations Hard to make low-level GUI (games) – limited support for colors, transparent images High-level GUI only at about same level as WAP 1.1 l No standard for communicating with phone functionality Cannot handle incoming communication (server sockets or messages) Only recommendations for provisioning/deployment

MIDP 2.0 l JSR 118, led by Motorola l Release: Q3 2002? Phones: Q2 2003? l Adds Game UI classes (spites, layers), UI Media classes (can play files or streams) Security: Trusted MIDlets and HTTPS Push message reception OTA deployment is required l

Other interesting specs l JSR-75: PDA Profile (public review) l JSR-82: Bluetooth (final release March) l JSR-120: Wireless Messaging (final release Aug) l JSR-135: Mobile Media API (final release Jun) l JSR-139: CLDC 1.1 (public review) l JSR-172: J2ME Web Services (just started)

Competition l Browsing (WAP): Only applicable for some uses l Pocket PC/.NET Compact Framework/Wince: Targets high-end devices, enterprise apps. But more powerful than MIDP. l Symbian/Palm OS/BREW/Motorola MIX: Device-specific; may be harder to deploy. But more powerful than MIDP. Source: ESRI

MIDP: Conclusion l MIDP 1.0 will be available on many devices l MIDP offers device independence and code download l MIDP 1.0 has many limitations, MIDP 2.0 will address most l MIDP is easy to master

Server Side Wireless Applications Browsing (WAP)Messaging (SMS, MMS) Voice (VoiceXML)

Server side applications

Mobile Browser Overview Java 2 Enterprise Edition WAP Gateway 3. WML 4. Compiled WML 1. OTA Request 2. HTTP Request Simple for the content provider!

Mobile Browser Overview Source:

WAP’s Failure l Too little, too late l Too slow l Limited service potential (billing) l Expensive to use! l Heterogeneous devices

WAP’s Comeback l Faster networks (GPRS) l Cheaper networks (GPRS) l Faster phones/browsers l Better browsers l Third party “multi-channel” software l WAP is having a renaissance

Typical Browser Services: l Information services Online address-book News l Product/company presentation l m-Commerce l m-Banking l Application download

Messaging l SMS, MMS, and WAP Push l SMS-interfaces not standardized l SMS still successful l MMS is standardized Based on SMTP or HTTP for transport, SMIL for presentation l Modern terminals support WAP push

MMS architecture Java 2 Enterprise Edition MMS Gateway 1. SMIL over HTTP or SMTP 2. Notification over SMS 3. Request and response over WAP Simple for the content provider!

Messaging Services l Configuration messages, pictures, ring-tones (Browsing services are better for this, though) l Alerts! Weather, traffic, news, stocks, Surveillance alarms: Control systems, cameras, panic-buttons Service Announcements l Chatting Can be enhanced with images

Messaging – Surveillance Alarm

Messaging – Service Announcement

Voice: What is It? l Voice was first phone killer app! l Most systems today: IVRs Recorded messages DTMF keys l On the horizon: VoiceXML Adds: Text-to-speech, voice command Provides an easy interface for service provider Metaphor: Filling out forms

Voice Architecture J2EE Server HTTP/ VoiceXML Voice Voice Browser Simple for the content provider!

Voice Services l Can be used with regular phones, pay-phones, and mobile phones l Challenging to design good UI Imagine a two-level menu with 5*10 options Imagine call-center maze syndrome l May be very powerful and user friendly l Killer app: Yellow pages, ticket ordering, directions

VoiceXML FAQ l Yes, it is available now! l Yes, it works! l Yes, it is available in Norwegian!

Comparison l J2ME/MIDP Offline use, graphics, games l Browsing (WAP) Information search and viewing l Messaging User-to-user, alerts, news, service announcement l Voice Broad user base, appropriate end-user usage

Will Java Lead to a Breakthrough in Wireless Services? l Terminal: MIDP 1.0 (J2ME) l Server side: HTTP services (J2EE) l The data services marked will increase l Data services will become ubiquitous l Find the added value propositions! l Java is positioned for the present and the future
