WLAN Of The PHS Network System

In order to eliminate the vice of the PHS network, China telecom developed the PHS radio access gateway base the PHS private protocol and theory. It integrated the telephone and the PHS CS module into the product. In house, if the PS can't find the signal of the PHS public network, it switch to the PHS private network automatically, and at the help of the PSTN/ISDN network, the PS can access the PHS network to comminute very nice.In my paper we use the which WLAN , PHS wireless access gateway as the access point of thePHS network systemWLAN, I will introduce the application of the WLAN - PHS private network.PHS radio access gateway as the access device, it can communicate with the phs point to multipoint through the air in its cover location, at the same time, when the phs public network become very weak, the phs can switch to the phs private network to communicate。I detail research the protocol of the PHS private network system in the paper, and described the design and realization of the PHS radio gateway. As a embedded system, optimization is paramount, so the paper also describe the Transplanting and configuration of the Embedded OS(NORTi3).
