The Design And Implementation Of Embedded WLAN Gateway Based On Linux

With the development of embedded system and network technique, the embedded Internet technique is popular with all kinds of social fields for its easy integration, low-overhead and wide application,particularly with the fields of remote control.The wide application of wireless technologies makes people's work and life more and more convenient and efficient. Wireless communication among terminals has become a trend. Because wireless communication has a certain degree of freedom within fixed space limits, it is very suitable for families or other middle-sized and small-sized places.This paper presents the design and implementation of embedded WLAN gateway based on Linux OS.At first it analyses the current situation and development direction of embedded systems and network technology.Then it discusses the hardware formation and software design of embedded gateway and wireless terminals.Ultimately we design and implement the embedded WLAN gateway and terminals which is under the control of remote clients using Internet.The embedded WLAN in this paper is composed of two parts:the embedded gateway and wireless terminals.The part of embedded gateway is based on Linux OS.The hardware we use is UP-NETARM2410-S development system. In the technology we at the same time use the Ethernet port which is linked with Internet and serial port which is connected with RFM12B wireless transmission module. The part of wireless terminals is implemented by Ling Yang SCM connected with STC12LE2052 wireless transmission module.Using this system, users from anywhere can control and monitor the remote WLAN terminals by logging in the interface of controlling gateway via Internet.
