论文摘要
Wi-Fi的可靠性和决定论可以通过无缝的冗余来切实提高，以使该技术适合工业环境。正如最近论文中指出的那样，当没有现象能同时影响冗余链接的所有渠道传播时，就可以实现最大的好处。在本文中，分析了几个方面，如果不正确地抵消，这可能会使无缝的冗余有效性恶化。它们对沟通产生的影响已在依赖商用Wi-Fi设备的实际测试床中进行了实验评估。然后，提供了实用的准则，旨在通过仔细的系统设计来防止联合干扰。结果表明，在理论上，测得的沟通质量可以像预期一样好。
Reliability and determinism of Wi-Fi can be tangibly improved by means of seamless redundancy, to the point of making this technology suitable for industrial environments. As pointed out in recent papers, the most benefits can be achieved when no phenomena can simultaneously affect transmissions on all channels of a redundant link. In this paper, several aspects are analyzed which, if not properly counteracted, may worsen seamless redundancy effectiveness. Effects they cause on communication have been experimentally evaluated in real testbeds, which rely on commercial Wi-Fi devices. Then, practical guidelines are provided, which aim at preventing joint interference through a careful system design. Results show that measured communication quality can be made as good as expected in theory.
