This blogpost is the final in a series of seven, inspired by the most frequently asked questions we receive regarding PROFINET.
PROFINET is based on Ethernet, which was technically invented in the 1970s –but has come a long way since then. It certainly seems like wireless is taking over as the primary way to move data in the consumer world, particularly with the upcoming versions of 5G cellular. While most PROFINET installations utilize Ethernet, many also seamlessly employ WiFi, Bluetooth, or eventually 5G. Ethernet works very well for its purpose and has improved along the way. This appears to be true for the future as well. Today, industrial Ethernet bandwidth can scale from 10 Mbps to 100 Mbps to 1 Gbps and beyond. Soon, Time-Sensitive Networking (TSN) stands to make Ethernet robust for even the most heavily loaded networks.
