Design And Realization Of Communication Signal Switch Based On Digital Radio And Wifi

In recent years, in the field of information communication, wireless communication technology has developed rapidly. At the same time,with the development of RF technology and integrated circuit technology, the wireless communication united with embedded.All of these make the realization of the wireless communication more and more easily, and transmission speed also more and more quickly. There are more and more solutions to solve needs of different wireless communication Yet at the same time, needs of different wireless communication become more complex.It is difficult to meet the need by one wireless solution. United the advantages of a variety of wireless solutions,and make it can find the best wireless solution by itself,will greatly convenient building wireless communication.In this article, we will use digital radio communication WIFI communication. Builded WIFI network platform is convenient.The transmission distance of WIF is long,and data transmission speed of WIFI is fast.The wireless solutions that are builded by WIFI are more. Digital radio can be use in some special conditions that need the real-time monitoring special network signal and the reliable data transmission.The cost of digital radio is low, and it can use in long distance. United the advantages of both, and make it can find the better solution in different environment by itselfDigital radio have no communication protocol, so the quality of data communication is not reliable. Through to design the protocol of digital radio communication, to make the quality of digital radio better.To make sure digital radio can provide reliable server.In this article, the application layer is still the top level protocol. Digital radio communication and WIFI communication are called communication layer.The communication layer is use to provide data to Upper Level Protocol and send the data that from Upper Level Protocol. Signal switching protocol is between communication layer and the application layer.And this level is called switch layer. The switch layer can ensure that communications signals switching in the right time, and also can ensure the data transmission quality when signals switching.
