GPRS and WAP

WAP is the standard of wireless internet, developed by several large vendors, it defines a layered, scalable architecture that provides a comprehensive solution for the wireless internet. One of the principles of WAP Protocol development is to be independent of the air interface, the so-called independent of the air interface refers to the WAP application can run on a variety of wireless hosting network, such as TDMA, CDMA, GSM, GPRS, SMS and so on.

GPRS corresponding to the GSM 9.6kbps data service, and the difference is that GPRS is through packet switching to achieve high-speed data transmission, in other words, GPRS is the GSM data Service improvement, is in the GSM to achieve high-speed data transmission means.

It can be seen that WAP is a high level application, and GPRS is the bottom transmission. You can cite the well-known examples of postal mail to illustrate the relationship between WAP and GPRS: If WAP is a regular mail or greeting card or postcard, then GPRS and GSM CSD (9.6kbps circuit Exchange data business) is the transport of letters, but the latter is the car, the former is a plane.

We believe that GPRS technology, as a kind of technology to cater for the rapid development and integration of GSM mobile communication market and global Internet, will lead people into the high-speed information age.
