It is a technical standard specified to access the information over a mobile wireless network. A Wireless Application browser is a web browser for mobile devices like mobile phones which uses the protocol. Mobile service providers had limited opportunities to offer interactive data services before the introduction of WAP, and needed the interactivity to support Internet and Web applications like Email by mobile phone, News headlines, Sports results and music and video downloads and follow the prices of stock-market, Internet access, and instant messages.
The Wireless Application Protocol set described as a protocol suite that allows the interoperability of WAP tools, and software with special network technologies, like GSM and IS-95 which is also known as CDMA.
Wireless Application Protocol Push is incorporate into the specification to allow the WAP content to push into the mobile handset with minimum user interference. A WAP Push is mainly a specifically encoded message that includes a link to a WAP address.
WAP Push is particular on the peak of Wireless Datagram Protocol (WDP); as such, it can deliver over any WDP-supported holder like SMS or GPRS. Most of the GSM networks have a large range of customized processors, although, GPRS activation from the network is not usually supported so WAP Push messages should be delivered on top of the SMS bearer.
WAP Layers are:
Wireless Application Environment (WAE), Wireless Session Protocol (WSP), Wireless Transport Layer Security (WTLS), Wireless Datagram Protocol (WDP), Wireless Transaction Protocol (WTP).
Wireless Datagram Protocol (WDP) is a function which adapts layer which makes every data network appear a bit like UDP to the upper layers which provide unstable transport of data with two 16-bit port numbers.
Wireless Transport Layer Security is an undependable transport of an optional layer. It provides a public key cryptography based security mechanism which is parallel to TLS. with two 16-bit port numbers.
WTP provides the transaction support adapted to the wireless world. WTP supports more efficiently than the TCP the difficulty of packet loss that occurs generally in 2G wireless technologies in most radio surroundings but is misinterpreted by TCP as network obstruction.
Multimedia Messaging Service (MMS) is a combination of WAP and SMS it is a spin-off technology which has further driven the protocol. An improved approval of device diversity, supported by the related changes to WAP content to become more device-specific to a certain extent aiming at a lowest common denominator. It allows for more working and convincing content. As a result adoption rate of WAP technology is rising.
The basic WAP model serves the pages in WML. It bases on the concept of documents called as decks. With data in every deck structured into one or more pages, each of that represents a single interaction with the user. With the start of responsive web design and mobile first approaches the test of resizing and adapting content have led to the concept of decks and pages to be recycled. Cards serve in columns and rows to match the device's capability and different decks can deliver to the device based on the network and device.
