What is a WAP Gateway?

1. What is a WAP Gateway?

WAP Gateway is a software. It connects to the Internet or Intranet, so that WAP phones can access resources in it. Some gateways may be able to convert HTML files to WML pages.
the WAP Gateway provides many functions in the connection between the WAP device and the web server. These functions are basically:

• convert the markup language (WML) from text to the encoding (Binary/compressed) format that can be read by Wap devices.
• converts requests from WAP devices to HTTP requests on the Web.
• implements SSL encryption and WTLS encryption conversion between the web and WAP.
• the transfer layer between the web and WAP implements the conversion between TCP and WDP.

gateways also have other optional functions, such as converting text files and HTML files into readable WAP formats. If the gateway is installed on the mobile operator side, the mobile operator may use the gateway to add some special information to the HTTP stream, such as the phone number and location information.
Some WAP gateways are made public on the Internet, but others are on the mobile operator's side, and are often limited to accept only WAP devices from the operator's side.
A few gateways, or devices like gateways ("WAP servers") are on the content provider's side, and these people own WAP content servers.

2. What is a WAP server?

Besides the integrated WAP gateway, the WAP Server is no more than the common web server. I personally think that the concept of "WAP Server" is very confusing. Many people think that there must be a WAP server to provide WAP content, but this is not correct. WAP content can be provided by any common web server.
What are the key points of the WAP server? When we discuss the security of WAP, the WAP Server can reduce security vulnerabilities in the WAP environment.
Since the WAP Server contains a gateway, you can skip the application installed on the third-party gateway of the mobile carrier and the host.ProgramProvides full control over encrypted data streams.
Note that to allow users to access the gateway, they need to configure their WAP device correctly. In most cases, they are manually configured.

3. Where can I get the WAP Gateway?

The Nokia gateway can be obtained at http://www.nokia.com/corporate/wap.

4. Is the WAP Gateway a physical device like a server? Is it from an Internet provider or a mobile provider?

WAP Gateway is a WAP Server software running on winnt or Linux machines. It can be anywhere on the internet, either on the Internet provider or on the mobile provider or on the user's PC.

5. After installing the Nokia WAP toolkit, how can I set up a gateway, dial-up, and so on so that I can use the user's home page?

Start the Nokia WAP toolkit and find menu> toolkit> preferences. Select the "use WAP Gateway" option to give the address of the WAP Gateway (127.0.0.1, if the Gateway Program runs on the local machine ). You can specify a URL from menu> go> load.

6. Which company provides the WAP ServerSource code?

Open source gateway is available at http://www.kannel.org.

7. Can I use a gateway in a wide area network?

The IP address of the gateway can be accessed through dialing.

8. Where can I find the gateway information?

In many cases, users may want to use multiple gateways to test applications. Because they work in different ways. Therefore, you may need to connect to other gateways, not just the gateways provided by mobile carriers.
Wapdrive.net has a very good list of public gateways:
Http://www.wapdrive.net/DOCS/wap_gateways.htm
There are some unpublished gateways. If the IP address starts with "10.", the gateway is private and owned by the carrier. Gateways of other IP addresses are not necessarily public gateways.

9. Why does the HTTP user_agent string differ in the phone.com Gateway?

If you view the HTTP header sent from the up. Link gateway of phone.com to the server, you will find that user_agent is different. Up. Link gateway writes the name and version name here.
If the user is a gateway from Nokia or Ericsson, The user_agent is like the following:
Ericssonr320/r1a
If the user is from the up. Link gateway, it is as follows:
Ericssonr320/r1a up. Link/4.1.0.1
They clearly show the type and version of the gateway. You can clearly understand the type and version of the gateway you are using.
