Why use wires?

At the technology evening on 11 September, Rudi Erasmus of Phoenix Contact walked us through when and why wireless communication is preferred to cabled communication.


Ann de Beer and Rudi Erasmus after the presentation.

Communicating with moving machinery is obviously one, but it is also preferable where long distances are involved, such as wastewater treatment plants, and pipelines, for example.

Apart from these obvious examples, Rudi also covered many of the technical aspects of wireless communication, including the bands they typically occupy, including protocols such as BlueTooth, and comparing them with Phoenix’s Trusted Wireless protocol, and where each has its niche.

Moving on, he also covered aspects of wireless propogation, antenna types, Fresnel zones, antenna polarisation and co-existence with other wireless channels.

The branch thanks Rudi and Phoenix for hosting the evening, and for making it memorable.
