Wireless Trend in 10 years
WAP Forum
Open Standard
Internet WWW application development model
Wireless Network Technology and bearer independence
Device independence
Embrace and extend existing standards.
WAP Forum Dates

Wireless Application Protocol
Protocol specification for communication over wireless devices
Specified by WAP Forum
Open, global specification
Conforming to OSI standards
You can say it is a parallel internet
WAP Key Features
WAP Architecture
WAP - Terminals

WAP Protocol Stack
Makes applications independent of bearers and other hardware
Modified to allow for
Lower Bandwidth (9.6kbps – 14.4kbps)
Network latency (6 – 10 seconds on SMS)
Unreliable connections
WAP Protocol Stack
Wireless Application Environment (WAE)
A micro-browser environment containing
Addressing Model (URL, URI)
Wireless Markup Language (WML)
WMLScript
Content Formats – WBMP, vCard, vCalendar
WTA User Agent
Handles wireless devices telephony functions
Wireless Session Protocol (WSP)
A strip down version of HTTP/1.1 (“B”)
Maintain session states
Session suspend, resume (long-lived sessions)
Wireless Transaction Protocol (WTP)
Three types of transactions
Unreliable one-way requests (class 0)
Reliable one-way requests (class 1)
Reliable two-way request-reply (class 2)
Reliability thru [selective] re-transmission
Wireless Transport Layer Security (WTLS)
WTLS is an optional layer
Privacy thru encryption
Authentication through digital certificates
Compression
Elliptic Curve Cryptography (ECC)
WAP Gateway
Connects the Internet domain to the Wireless domain.
Cache service
Script compilation
Protocol conversion
Security provided with WTLS, which supports authentication and encryption
Compressed Binary Transmission
WAP Server
Hosts WAP applications
Allows WAP services to be hosted on standard WWW servers using proven technologies like ASP, Java Servlets, CGI scripts …
Provides security and authentication
WAP content is created using WML, which is a light weight HTML.
Gateway and server functions can be combined into a single physical server.
WAP - Services, Business areas
Information services
WAP Portals
E-commerce
Banking and finance
Shopping
Gambling
Ticketing
Advantages Vs Disadvantages
Simplicity of Use
Mobility
Personalized
Easy to Carry
Low Band Width
Battery life
Limited Computation Power
Limited on board storage
Limited Graphics
Limited Keyboard and Display screen Size
WAP - potential threats
Delayed standard roll-out
WAP 1.0 WAP 1.1, a developer drawback
WAP 1.2 in December, 1999
Pricing
Security
End-to-end security problems
Marketing
Competition
Microsoft Wireless Knowledge (Microsoft-Qualcomm tie-up)
Palm VII (Palm Computing)
I-mode (NTT) , currently most developed but limited
SIM TOOLKIT, will be a complementary solution
Future …
Leverage IVR (Interactive Voice response) technologies to reduce data entry woes.
Location and proximity detection technologies
Evolution of Wireless networks towards 3 and 4G.
