2、arcode scanner with 2.4GHz MiWi technology Abstract With the improvement of the industries and business automation, barcode is used more and more widely, the bar code scanner also got rapid development. And the wireless

3、barcode scanner is also applied to many places for it has eliminated the limitation of the wire and can be used more freely. The wireless module is one of the key parts of the wireless barcode scanner design, because it

4、will affect the wireless connection, data transmission rate and power consumption. MiWi wireless network protocol is a low data rate, short distance, and low cost network solution provided by Microchip. It is based on IE

5、EE 802.15.4 which is for wireless personal area network (WPAN). MiWi provides easy to use program and it is for small applications, these applications network scale is relatively small, the distance between nodes are sho

6、rt. The MiWi uses Microchip MRF24J40 2.4 GHz transceiver, which accords with IEEE 802.15.4 network. This paper discusses in detail about how to integrate the MiWi wireless solutions into wireless bar code scanner. It int

7、roduced the MiWi wireless module and the hardware and software’s design of the wireless barcode scanner and also describe the problems need to care about during design, at the end, it also tested the performance in a rea
