Requirements for Reliable Wireless Industrial Services
draft-sofia-raw-industrialreq-00
Abstract
This document provides an overview on communication requirements for
handling reliable wireless services within the context of industrial
environments. The goal of the draft is to bring awareness to
communication requirements of current and future wireless industrial
services; how can they co-exist with wired infrastructures; key
drivers for reliable wireless integration; relevant communication
requirements to take into consideration; current and future
challenges derived from the use of wireless.

1. Introduction
Within industrial environments, short-range wireless standards, such
as IEEE 802.11ax, are gaining prominence as there exists an
increasing need for flexibility in terms of infrastructure layout, of
processes support. Wireless, and specifically Wireless Fidelity (Wi-
Fi), is now reaching a maturity point where the available
transmission rates become highly competitive in comparison to wired
environments, thus increasing flexibility, providing a lower cost and
higher availability in scenarios requiring, for instance, mobility
support. There are, nonetheless, barriers to the integration of
wireless in industrial environments. Firstly, being wireless a
shared medium, it experiences challenges such as interference and
signal strength variability depending on its surroundings. These
features raise issues concerning critical services availability,
