Description
A tablet PC commonly known as tablet is a mobile PC. It typically comes with a mobile operating system i.e. android, LCD touchscreen display, and a rechargeable battery in a single-thin flat package.
Before the invention of the wireless LAN WLAN, people want to communicate and communicate through the network. We must first use the physical cable - copper strand to form an electronic operation path. In order to improve the efficiency and speed, then the optical fiber was invented. When the network has developed to a certain scale, it is found that this cable network is very difficult to be set up, disassembled or restructured on the original basis, and the cost and cost are very high, so the networking mode of WLAN emerges as the times require.

A warehouse generally refers to a place where storage facilities are used to concentrate, collate, store and distribute articles (materials).
Telecommunications, or telecommunications (English: Telecommunication), is a way of communication using electromagnetic equipment to transmit information by wire, radio or light. Telecommunications originated in cable telegram and cable telephone invented in nineteenth Century. The invention of radio in twentieth Century and the emergence and development of electronic tubes, transistors and integrated circuits brought telecommunications to a new period of development. The applications of wireless telegraphy, broadcasting, television, satellite communications, data communications, fiber communication, and the Internet, etc. Profound changes have taken place in the human society.

This report studies the Enterprise Media Gateways market. Enterprise media gateways are translation devices or services used to convert the digital media flow between telecom networks such as signaling system 7 (SS7) and public switched telephone network (PSTN). Multimedia communications are enabled by media gateways over various transport protocols such as Asynchronous Transfer Mode (ATM) and Internet Protocol (IP) across next-generation networks. As the media gateway is used for different types of networks, one of its major functions is conversion between different coding and transmission techniques. Media gateways are used for the conversion of voice and multimedia data in various enterprise applications. Enterprises use media gateways to extend the life of applications such as legacy time-division multiplexing (TDM) and private branch exchange (PBX) to introduce IP-based technologies. Media gateways help preserve existing line equipment in the enterprise.
