  The manufacturing industry is at the edge of the 4th industrial revolution, a
paradigm of integrated architectures in which the entire production chain
(composed of machines, workers and products) is intrinsically connected.
Wireless technologies can add further value in this manufacturing revolution.
However, we identify some signs that indicate that wireless could be left out
from the next generation of smart-factory equipment. This is particularly
relevant considering that the heavy machinery characteristic of this sector can
last for decades. We argue that at the core of this issue there is a mismatch
between industrial needs and the interests of academic and partly-academic
(such as standardization bodies) sectors. We base our claims on surveys from
renowned advisory firms and interviews with industrial actors, which we
contrast with results from content analysis of scientific articles. Finally we
propose some convergence paths that, while still retaining the degree of
novelty required for academic purposes, are more aligned with industrial
concerns.
