Wi-Fi network planning and deployment can be a daunting task for most business operators. Network engineers need to carefully select network equipment, do site planning, deploy equipment, set optimal network parameters, and continuously tweak the network parameters to get the best possible performance. Any glitch in an industrial network can cause a shutdown of critical applications controlling industrial processes, with disastrous results. As more and more industrial operators switch to Wi-Fi technology, there is a need to build reliable Wi-Fi infrastructure that can outperform conventional networks. In this article, we discuss some key points to consider when planning and deploying a Wi-Fi network in an industrial environment.
