Simple read WAP communication protocol

Who once thought that the Internet has spread to all aspects of our lives. Especially in the field of communication, network is indispensable. The WAP communication protocol in the communication field is our mainstream mobile network protocol. In the past, wireless Internet access has been restricted by mobile devices and wireless networks. The WAP Communication Protocol makes full use of Internet standards such as XML, UDP, and IP. Many of its procedures are based on Internet standards such as HTTP and TLS, but are optimized, overcome the disadvantages of low bandwidth, high latency and poor connection stability in the original wireless environment.

The original Internet standards such as HTML, HTTP, TLS, and TCP are far from meeting the requirements for mobile networks, because huge text data information needs to be transmitted. The standard HTML content cannot be effectively displayed on a cell phone or pager's small screen. WAP uses binary transmission to compress data more, and its optimization function is suitable for longer wait time long latency) and low bandwidth. The WAP session system can handle intermittent coverage intermittently), and perform operations under various conditions of wireless transmission.

WML and WML scripts are used to create WAP content, so that you can maximize the use of small screen display. The WAP content can be displayed on the screen of two lines of text from one of the latest smart phones or other communication devices. It can also be changed to a full-image screen display.

The lightweight WAP procedure stack memory design minimizes the required bandwidth and maximizes the number of wireless network types that provide the WAP communication protocol. It IS applicable to a variety of networks, such as the Global Mobile Communication System GSM900, GSM1800 and GSM1900; Transitional Standard IS)-136; European standard DECT; Time Division Multiple Access; personal communication business, high-speed paging FLEX) and code division multiple access. It also supports all network technologies and bearer services, including short message service (SMS), unstructured auxiliary service data (USSD), and circuit switching cellular mobile data (DSD), cellular mobile digital grouping data CDPD) and general grouping wireless service GPRS ). Because WAP is built on a scalable layered structure, each layer can develop independently of other layers. This allows you to introduce other bearer services or use new transmission procedures without changing layers.

WAP allows users with small wireless devices such as mobile phones and PDAs that can browse the Internet to access the Internet. WAP takes into account the limitations on those devices and considers the flexibility requirements of these users. Limitations of handheld WAP Devices

Compared with PCs, WAP devices have limited capacity for low-resolution small display input devices. What is important is that they do not provide fixed-point devices with low-power CPUs, compared with the HTML-C, WAP Standards do not specify the form of WAP device, because the bandwidth of the network is narrow and the connection is unstable. This is extremely beneficial to device manufacturers so that they can produce different types of devices to meet different needs. In the near future, market requirements for WAP devices will be based on Browser display sizes, input devices, and memory sizes, this will promote the development and progress of WAP devices in new technologies and solutions.

Using a mobile phone to connect to the Internet will soon become a standard, and WAP is a technical tool to achieve this standard. Today, the number of mobile phones accessing the Internet is growing faster than the number of PCs accessing the Internet. This means that most new mobile phones will soon be equipped with WAP browsers. Wireless users with WAP devices can obtain related services through the Internet. The web page is compiled in HTML format. At that time, for many, but most users, WAP Communication Protocol devices will become a common tool for them to obtain these services.
