G in 1G, 2G, 3G and 4G means the “generation” of the mobile network. Today, mobile operators have started to offer 4G services in higher numbers, before the "G" stood for more power to send and receive more information and therefore the ability to achieve greater efficiency via the wireless network. In the 1G era, radio signals were transmitted in “analog” form. 2G networks, on the other hand, were based on narrow-band digital networks. The 3rd generation of mobile networks have become popular and users are accessing the Internet through devices such as mobiles and tablets. This means that a 3G network actually allows more data transmission and therefore enables voice and video calls, file transmission, internet browsing, online television, high definition video viewing, gaming and much more. even more. 4th generation mobile networks are believed to offer many value-added features.1. Compare the advantages and disadvantages of 3G and 4G technologies to determine the best uses of 3G and 4G technologies in today's applications. The main comparisons of advantages and disadvantages between 3G and 4G can be summarized as follows: Architectural difference: 3G network architecture is the basis of radio terminals. The stations (BTS) group together radio access. Wireless Markup Language (WML) is used to create pages that can be delivered using WAP. WML is a language that allows textual portions of web pages to be presented on cellular phones and personal digital assistants (PDAs) via wireless access. WML is part of the Wireless Application Protocol (WAP) proposed by several vendors to standards bodies. The wireless application protocol operates on top of standard data link protocols, such as Global System for Mobile Communications, Code Division Multiple Access and Time Division Multiple Access, and provides a comprehensive set of network communications programs comparable to and supporting the entire Internet. of
