         Requirements for Reliable Wireless Industrial Services


   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,
