The Characteristics of WAP Technology

The past, wireless Internet access has been subject to mobile devices and wireless network restrictions. WAP full use of, such as XML, UDP and IP and other Internet standards, many of its established order in the HTTP and TLS, and other Internet standards, but has been optimized to overcome the original low-bandwidth wireless environment, high delays and poor stability of the link Ills.

The original Internet standards such as HTML, HTTP, TLS and TCP for mobile network is far from meeting the requirements of the text because the great need for data transmission. Standard HTML can not be effective as displayed on the pocket-sized mobile phones and pagers on the small screen.

WAP use binary transfer to greater data compression, while its optimization feature suitable for a longer waiting time (long latency) and low bandwidth. WAP system can handle the conversation intermittent coverage (intermittent coverage), while in the wireless transmission of the changes under the conditions of operation.

WML and WAP WML Script for the production of content that can maximize the use of small screen display. WAP content from a new type of smart phones or other communications with the two lines of text displayed on the screen, can also be transformed into a full-screen image.

Lightweight WAP protocols stack-memory design will need to minimize the bandwidth, so as to provide WAP content types to the largest wireless network. It applies to a variety of networks, such as global system for mobile communications GSM900, GSM1800 and GSM1900; transitional standard (IS) -136; European standard DECT; TDMA access, personal communications services, high-speed paging (FLEX) and code - Multiple access, and so on. It also supports all the network technology and carry business, including Short Message Service (SMS), supporting non-structured business data (USSD), circuit-switched cellular mobile data (DSD), cellular mobile digital packet data (CDPD) and GM - Wireless Business Group (GPRS). Since the establishment of WAP in the escalation of the hierarchical structure, based on a tiered be independent of the other layered and development. This makes the need for other changes in circumstances stratification can be introduced into other bearing on the business or use the new transfer order.

WAP makes those with a small wireless devices such as the Internet can visit the mobile phone and PDA users, such as mobile Internet access can achieve access to information. WAP to take into account the constraints faced those equipment and taking into account the flexibility of these users for the request. Handheld devices WAP equipment and the limitations of WAP compared to PC: low-resolution small screen input device with limited capacity, it is important not to provide low-power devices designated CPU, memory and less energy than the network bandwidth is narrow and unstable WAP connection instability brought about by more flexibility compared with the HTML-C, WAP standard does not provide WAP equipment should be what form. This equipment manufacturers extremely favorable, to enable it to produce various types of equipment to meet different needs. In the near future, WAP equipment on the market demand will be the browser screen size, input devices and memory size, and so on the basis of different and thereby facilitate the WAP equipment in the new technology and solutions to development and progress.

Through the use of mobile phones connected to the Internet will soon become a standard, and the WAP is to achieve this standard technology tools. Today, the number of mobile phone Internet PC growth rate than the growth of the Internet faster. This also means the near future, most new mobile phones will be equipped with WAP browser. Holders of WAP users of wireless devices available through the Internet to provide related services, the establishment of network pages in HTML format. For many even when the majority of users, WAP access to its facilities will become a common tool for these services.
