WAP Wireless Communication Protocol

When the use of networks expands to mobile communication, the network protocol in the mobile communication field is WAP wireless communication protocol. We should be familiar with this Protocol. In traditional 2G networks, we use this protocol. WAP (Wireless Communication Protocol) is used on digital mobile phones, the internet, or other personal digital assistant machines (PDAs) global Open Standards for communications between computer applications and future information appliances. The birth of this standard was the result of the efforts of members of the WAP Forum. The WAP Forum was held in June 1997, composed of Nokia, Ericsson, Motorola, and Unwi redPlanet ｡

With the WAP technology, you can introduce a large amount of Internet information and various services to wireless terminals such as mobile phones and PALM. wherever and whenever you need information, you can open your WAP mobile phone and enjoy endless online information or resources ｡

WAP can run on various Wireless networks, such as GSM, GPRS, and CDMA. WML is a Wireless Makeup language) the mobile phone that supports the WAP wireless communication protocol can browse the Internet content described by WML ｡

WML is an XML-based markup language used in standardized narrow-frequency devices, such as mobile phones, receivers, and other languages for displaying content and user interfaces. Due to the narrow-frequency, WML is partially restricted, such as small displays, limited user input devices, narrow-frequency network connections, and limited memory and resources ｡

WML supports text and image display. In the content organization, a page is a Card, and a group of cards constitute a Deck. When a user requests a browser from the server, WML sends the entire Deck to the browser of the client, so that the user can view all the Card content in the Deck without downloading each Card from the network ｡

With the technology of WAP wireless communication protocol, a large amount of Internet information and various services can be introduced to wireless terminals such as mobile phones and PALM. Whenever and wherever information is needed, by enabling the WAP mobile phone, you can enjoy endless online information or resources. For example: comprehensive news, weather forecasts, 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 anytime, anywhere, and interesting news in the entertainment circle., you can also use the online booking function to arrange your life in an orderly manner ｡

WAP wireless communication protocols include the following:

1. WirelessApplicationEnvironment (WAE)

2. WirelessSessionLayer (WSL)

3. WirelessTransactionLayer (WTP)

4. WirelessTransportLayerSecurity (WTLS)

5. WirelessTransportLayer (WDP)

Among them, the WAE layer contains micro-browser, WML, WMLSCRIPT Interpreter and other functions. 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 as much as possible consistent with existing standards, to maximize the protection of investment by manufacturers and application developers, the existing WWW programming model is used to a large extent, application developers can continue to use their familiar programming models and existing tools (such as Web servers and XML tools). In addition, the WAP programming model also targets the communication characteristics of wireless environments, the original WWW programming model is optimized and expanded ｡

In terms of bandwidth, WAP uses the "lightweight protocol stack" to optimize the current protocol-layer dialog to minimize the bandwidth required for wireless mobile phone access to the Internet, this ensures that the existing wireless networks can comply with WAP specifications. By using the WAP protocol stack, mobile phones can save a lot of wireless bandwidth for wireless networks. For example, they can query a stock index, if you use a desktop browser of HTTP1.0 to complete more than twice the packet traffic involved through a WAP browser, the number of packets used by the WAP wireless communication protocol is less than the standard HTTP/ half of the TCP/IP protocol stack ｡

Currently, WAP is not mature enough in many aspects, but it is enough to open up a new communication field, providing enough technical standards for wireless networks, so that the Internet can be truly ubiquitous ｡

Currently, wireless communication protocols are mainly available in versions 1.2 and 2.0. The latter is the trend. Low-end mobile phones only support version 1.2. Currently, mainstream mobile phones support version 2.0. with version 2.0, the content browsed by a mobile phone is more vivid. It can also have background music and background pictures like a computer station to make the original monotonous mobile phone webpage colorful ｡
