Mainly, I would like to know what are the challenges present from the point of view of Industry 4.0 where service reliability and availability is very high.
URLLC, ultra reliable low latency, is one of the extreme use cases on the famous triangle of use of 3GPP, adopted by ITU-T.
Manufacturing of the future, as targeted by the national project of Germany "Industrie 4.0", has delivered in DIN/DKE a well-defined architecture RAMI4.0, which is looked at with interest also outside of Germany.
Now, one very practical thing to bear in mind is that in demanding advanced manufacturing environments, production machines usually need to be plugged to the mains for electricity supply. If the machine has one compulsory cable, then adding an optical fibre next to it for very high speed communication, is not too much of a burden. Hence the "no wire" benefit of radio communications is not so compelling.
However, for "space-moving parts" such as robots/autonomous trolleys, bringing supplies from/to the stationary machines of the advanced factory, the wireless URLLC benefit is more convincing.
For logistics, including containers, a reasonable strategy is a mix of URLLC and mMTC (massive machine type communication, e. g. with Low Throughput Networks as specified at ETSI-ISG-LTN, as ELTRES, with priority to range and coverage over transmitted communication packet size).
Let me know if you have questions
Thanks a lot for the answers Renaud Di Francesco and Mayada Faris Ghanim .
I have one query that I would like to ask -- Is there any incident of network failure which has led to an adverse effect in an industry environment (e.g process shutdown, reduce output or accidents)? I have tried to search but unfortunately did not find any example.
Since 5G URLLC will replace the existing Ethernet TSN network; if we can point to any mishap then it will make the reliability and availability criteria more compelling.
@Sanju Das, here is one idea:
