The Market of the Cellular Tecnology

Based on information of the Strategis Group, there are already 530 million of celullar phone subscribers in the world in the year of 2001. In Brazil country at the end of 2000 year, we had 18 million of people using mobile phones, just 8 million more than the previous year. The forecast for the 2004 year indicates that the 1 billion barrier of world wide mobile subscribers will be broken. The figures for Brazil will be 58 million of mobile phone users.

The brazilian market estimates that 1 million of users will move to the new tecnology at the first year, and the forecast for the future, indicates that all users of A and B mobile bands of telephony will migrate to the wap tecnology. The first pratical result should be the tariff reduction. It will be the weapon used by the operators to attract customers. The reduction of the tariffs is estimated to reach 50%.

Mobiles Phones of Third Generation

One significant parcel of this number will be of mobile phones with multimedia resouces The multimedia capacity includes the ability to receive e-mails, receive from and send to Internet information - that means, Internet navigation, the same way we do in the desktop computer. In Brazil, the new frequencies differencial is the tecnological innovation: the C, D and E bands have " Internacional roaming" , voice, image and data transmition

through the Internet and GPS service (location via satellite) and videoconference. The C, D and E bands will use the GSM (Global System for Mobile Communication) european system , used by 250 million of people all over the world ( except the USA, Mexico, Argentina, Colombia, Dominican Republic and Singapure).

The WAP Tecnology

The Wireless Application Protocol (WAP) is a world standard for presentation and delivery of information and telephony services for mobile phones and other wireless communication devices ( such as PDAs - Personal digital assistants, Pagers, and other wireless communication devices).

WAP Forum

Ericsson, Nokia, Motorola and Phone.com founded the WAP Forum in 1997. This forum has today more than 400 members, that includes wireless service providers, handset manufactures, infrastructure providers and software developers (applications , development tools, etc), telephony network operators, wap content suppliers, among others. The various goals of the WAP Forum we can enfasize the following: to bring Internet content and advanced data services to wireless phones and other wireless terminals; to create a global wireless protocol specification that works across all wireless network technologies (GSM, CDMA, TDMA, SMS, USSD, etc).

WAP Specification

Is the major achievement because it defines for the first time an open,

standard architecture and set of protocols intended to implement wireless Internet access. It defines one WAP programming model that uses XML tools, Web Servers, very similar to the programming model of the World Wide Web (WWW). It defines one WML language (Wireless Markup Language), and one script language WMLScript used in conjunction with WML. It specifies one microbrowser for wireless terminals and other WAP tecnology devices that controls the user interface and the Internet access. It defines one lightweight protocol stack apropriated for the wireless network bandwith requirements (WAE, WSP, WTP, WTLS, UDP/IP e WDP). It defines a framework for Wireless Telephony Application (WTA), such as: call control, phone book access and messaging from within WMLScript applets.

Conclusion

The Internet is the leading segment of the information tecnology in growth. And WAP mobile technolog is the explosive growth inside of the Internet. Try and sure you are going to fall in love with the WAP technology. It is one resource that came to stay forever with us. Will be impossible live without it in the near future.
