Embedded Wireless Communication System Design

Traditional conference mode consists of the central server and the clients connect to the server component,with central server ctrols the meeting proceedings. This is a typical client / server mode, if the hosts in the network need to communicate with each other, you must first set up a central server, which is very convenient. And if the central server crash or disconnect, all connected users will lose connectivity,and the meeting will end.In view of the above-mentioned problems of existing technologies, this paper presents a wireless local area network voice communication system without server support. The entire communication system includes voice communication based on RTP, dual-core communication, compression algorithms and interface control management modules. I am responsible for voice communications and interface control management module. And voice and data transmission module are based on RTP protocol. Interface control module is designed with QT , Finally, we implement a graphical interface to control the whole system.This paper first analyzes communication technology used in this system , introduces the system hardware and software development platform, and then details the system design process ,including the development environment set up, bootloader, kernel, file system migration, prepares the voice procedures and the interface-related design and implementation. Finally, On this basis, we analyze the performance of the system, as well as areas to be improved, and propose the corresponding improvement program.
