433 MHz的机器对机器通信越来越受到人们的关注。本文介绍了基于国际标准化组织/国际电工委员会18000-7的433兆赫兹无线传感器通信的有源射频识别联盟标准--DASH7联盟协议。首先，解释了433 MHz通信与更频繁使用的频率(如2.4 GHz和868/920 MHz)的主要区别。随后，以自顶向下的方法描述了DASH7联盟协议的一般概念，如BLAST组网拓扑和不同的OSI层实现。基本的DASH7功能，如广告协议、自组织同步和基于查询的寻址，被用来解释不同的层。最后，本文介绍了一个软件栈实现OSS-7，它是DASH7联盟协议的开源实现，用于测试、快速原型和演示。
433 MHz is getting more attention for Machine-to-Machine communication. This paper presents the DASH7 Alliance Protocol, an active RFID alliance standard for 433 MHz wireless sensor communication based on the ISO/IEC 18000-7. First, the major differences of 433 MHz communication compared to more frequently used frequencies, such as 2.4 GHz and 868/920 MHz are explained. Subsequently, the general concepts of DASH7 Alliance Protocol are described, such as the BLAST networking topology and the different OSI layer implementations, in a top-down method. Basic DASH7 features such as the advertising protocol, ad-hoc synchronization and query based addressing are used to explain the different layers. Finally, the paper introduces a software stack implementation named OSS-7, which is an open source implementation of the DASH7 alliance protocol used for testing, rapid prototyping, and demonstrations.
