what is wap

wap (Wireless Application Protocol) is a global network communication protocol. It makes the mobile Internet a common standard, and its goal is to introduce the rich information and advanced services of the Internet into wireless terminals such as mobile phones.

The wireless application protocol defines a universal platform that converts HTML (an application under the Standard General Markup Language SGML) information on the Internet into The information described by WML (Wireless Markup Language) is displayed on the display screen of the mobile phone. WAP only requires the support of mobile phones and WAP proxy servers, and does not require any changes to the existing mobile communication network protocols. Therefore, it can be widely used in GSM, CDMA, TDMA, 3G and other networks.

WAP (Wireless Communication Protocol) is a global open communication between digital mobile phones, the Internet or other personal digital assistants (PDA), computer applications and even future information appliances standard. The birth of this standard is the result of the efforts of members of the WAP Forum, which was jointly formed in June 1997 by Nokia, Ericsson, Motorola and UnwiredPlanet.

Through WAP technology, a large amount of Internet information and various services can be introduced into wireless terminals such as mobile phones and PALM. No matter where and when you need information, you can open your WAP phone and enjoy endless online information or online resources.

WAP can run on various wireless networks, such as GSM, GPRS, CDMA, etc. WML is the English abbreviation of Wireless Markup language. Mobile phones that support WAP technology can browse Internet content described by WML.

WML is a markup language based on XML (a subset of the Standard Universal Markup Language). It is a language used to standardize how narrow-band devices, such as mobile phones and pagers, display content and user interfaces. Because of the narrow band, WML is subject to some limitations, such as smaller displays, limited user input devices, narrow band network connections, limited memory and resources, etc.

WML supports text and picture display. In terms of content organization, a page is a Card, and a group of Cards constitutes a Deck. When the user makes a browsing request to the server, WML will send the entire Deck to the client's browser, and the user can browse the contents of all Cards in the Deck without downloading each Card separately from the network.

Through WAP technology, a large amount of information and various services from the Internet can be introduced into wireless terminals such as mobile phones and PALM. No matter when and where information is needed, users can enjoy endless online information or online resources by turning on the WAP phone. Such as: comprehensive news, weather forecast, stock market dynamics, business reports, current exchange rates, etc. E-commerce and online banking will also be implemented one by one. Through WAP mobile phone users can also obtain sports competition results, entertainment industry anecdotes, etc. anytime and anywhere to add spice to life. They can also make use of the online booking function to arrange their lives in an orderly manner.

Type

1、Wireless Application Environment（WAE）

2、Wireless Session Layer（WSL）

5、Wireless Datagram Protocol (WDP)

Among them, the WAE layer contains functions such as micro-browser, WML, WMLSCRIPT interpreter and so on. The WTLS layer provides basic security functions for wireless e-commerce and wireless encrypted data transmission.

A very important guiding ideology of the WAP Forum is to make WAP consistent with existing standards as much as possible to maximize the investment protection of manufacturers and application developers. To a large extent, the existing WWW programming model is utilized. Application developers can continue to use their familiar programming models and utilize existing tools (such as Web servers, XML tools), etc. In addition, the WAP programming model also optimizes and expands the original WWW programming model according to the communication characteristics of the wireless environment.

In terms of bandwidth considerations, WAP uses a "lightweight protocol stack" to optimize protocol layer conversations, minimizing the bandwidth requirements for mobile phones to access the Internet, ensuring that existing wireless networks can comply with WAP specifications. Mobile phones can save a lot of wireless bandwidth for wireless networks by using the WAP protocol stack. For example, to complete a stock index query operation, if it is completed through a desktop browser using HTTP 1.0, it will be more involved than through a WAP browser. The packet communication volume is more than twice as large. The number of packets used by the WAP protocol is less than half that used by the standard HTTP and TCP/IP protocol stacks.

WAP is not mature enough in many aspects, but it is enough to open up a new communication field and provide sufficient technical standard foundation for wireless networks to make the Internet truly ubiquitous.

WAP mainly uses two versions, 1.2 and 2.0. The latter is the trend. Low-end mobile phones can only browse version 1.2. Mainstream mobile phones already support version 2.0. With version 2.0, the content browsed on mobile phones is more vivid. , it can also have background music and background pictures like a computer website, making the originally monotonous mobile web page colorful.

“The core of WAP Advertising 2.0 is to allow mobile phone users to participate more in the shaping, dissemination and viral marketing of advertising, creating a virtuous cycle of advertising and creating more value for advertisers, media and customers!” Baifentonglian Proposed the concept of "WAP Advertising 2.0" and launched WAP advertising products based on this concept. It uses the publishing system (L-Sense) to segment users, which can make the division of mobile phone users and customer groups extremely detailed and professional. Based on user customization, by better controlling the type, quantity, time and area of ​​advertising, we can achieve the best results with strong targeting, low output, and high output value.
