Design and Implementation of Embedded Wireless Smart Gateway Based on PXA270
To release the connection problem between two different wireless communication technologies in conventional smart home system, a new embedded wireless smart based on PXA270, Zigbee and GPRS was designed. Web server was built on embedded system which uses PXA270 as core, and the exchange of information between internal network and the Internet via Zigbee module and GPRS module. ZigBee network mainly for short-distance communication and the GPRS network mainly for long-distance communications, so they can on the basis of complementary advantages to achieve a long-distance data transmission linked together by gateway. This paper presents the hardware architecture and the software implementation process. The experimental results show that this system has advantages of high reliability and low cost, so it can be applied to environmental monitoring and the smart home system
