Unfortunately, Ethernet based network is not without problems, especially when time critical traffic
is concerned. In the office setting, reaction time for remote site within 100ms is acceptable, while
industrial machinery and IIoT often requires times within microseconds.

To address this issue, various approaches are used, Encapsulated Field Bus, fast addressing using only
Ethernet hardware addresses, traffic prioritising among multiple channels and so on.

The real challenges start with integration of old – even analogue – communication channels into
modern network. This requires often good understanding of the industrial processes, creativity and
very often investments, as there is basically no “one fits all” approach.

Wireless Communication

Very often, IIoT (and in fact, IoT) requires wireless connection to be feasible. Over last 20 or so years,
multiple technologies, with different purposes. Most known, WiFi (based on 802.11 standard) is
excellent for home laptops, high throughput and bandwidth, but power hungry and with security
problems. It is also easily congested with multiple access points overlapping.
