Develop Wireless Barcode Scanner With2.4GHz MiWi Technology

With the improvement of the industries and business automation, barcode is used moreand more widely, the bar code scanner also got rapid development. And the wirelessbarcode scanner is also applied to many places for it has eliminated the limitation of thewire and can be used more freely. The wireless module is one of the key parts of thewireless barcode scanner design, because it will affect the wireless connection, datatransmission rate and power consumption.MiWi wireless network protocol is a low data rate, short distance, and low costnetwork solution provided by Microchip. It is based on IEEE802.15.4which is forwireless personal area network (WPAN). MiWi provides easy to use program and it is forsmall applications, these applications network scale is relatively small, the distancebetween nodes are short. The MiWi uses Microchip MRF24J402.4GHz transceiver,which accords with IEEE802.15.4network.This paper discusses in detail about how to integrate the MiWi wireless solutions intowireless bar code scanner. It introduced the MiWi wireless module and the hardware andsoftware’s design of the wireless barcode scanner and also describe the problems need tocare about during design, at the end, it also tested the performance in a read model.
