Any place carries on the correspondence with any individual the desire. The mobile munication realizes in the future the ideal persontoperson munication service way that must be taken. In the information support technology, the market petition and under the demand bined action, the mobile munication technology39。s HSCSD。s DataTAC, Ericsson39。s GPRS. application actuates the market The wireless data traffic39。s target market will be the sales personnels or scene engineer such user group. Sends the goal from these in the application to accumulate the wireless data the first experience, and profits. In the past39。s dividing line bees fuzzy, the people need not to divide, the place visit very important information. Will occur will bee the actuation wireless data traffic development on the user body39。s influence Are the same with correspondence other domains, a wireless data traffic most important driving influence from Internet. According to the recent research, two year Europe39。s yearly rate will reach as high as 300%, obviously the user will turn on Internet39。s demand, global open agreement wireless application protocol (WAP) arises at the historic moment. WAP was transmits the Internet information content as well as the valueadded service to the mobile termination has provided one kind of open general standard, has realized IP and the GSM network bridge joint, was one provides accelerates the market for the manufacturer to grow, to avoid the network cleft grafting, protecting the standard which the operator invested, WAP guaranteed that any handset could work with WAP the patible GSM. （2）data rate development The GSM bearer service provides the GSM data rate is highest can only achieve (HSCSD) technology will realize the 57kbit/s data rate, to requested the continual bit rate and the transmission latency small application is ideal, like videoconference, , longdistance turning on enterprise39。s pursue to move toward successfully anytime and anywhere. Mobile munication39。s next stage is and even moves the multimedia shifts personally to the wireless data, this progress already started, and will bee in the future the important point of growth. Will move personally multimedia will supply is unable to imagine, consummation individual service and the wireless information according to the place for the people, will work to the people with life each aspect has the influence. In individual multimedia world, the voice mail and the are transmitted to move in the multimedia mailboxes。 The voice call will unify with the realtime image, produces th
