Industrial Wi-Fi with Scott McNeil

In this episode, we are talking about Wi-Fi in the Industrial environment with Scott McNeil. Scott has great experience designing, deploying and troubleshooting Wi-Fi and these environments and share his experiences with us! We are also talking about how the Industrial 4.0 revolution will impact how we will be using Wi-Fi in an industrial environment. Enjoy!
