        5G - Ultra-Reliable Wireless Technology with Low Latency
                         draft-farkas-5g-raw-00

Abstract

   This document describes the features of 5G that make it a wireless
   technology providing ultra-reliability, high availability, and low
   latency; and looks out to possibilities on the application of 5G
   together with IETF Deterministic Networking (DetNet).

1.  Introduction

   5G is a highly predictable scheduled wireless technology.  Equipped
   with Ultra-Reliable Low-Latency Communication (URLLC) features, 5G
   provides ultra reliability and high availability as well as low
   latency for critical communications.  That is, 5G is a Reliable
   Available Wireless (RAW) technology.  Its characteristics make 5G
   perfectly suitable to be part of deterministic networks, e.g.,
   industrial automation networks.  Furthermore, 5G already includes
   features and capabilities for integration with deterministic wireline
   technologies such as IEEE 802.1 Time-Sensitive Networking (TSN)
   [IEEE802.1TSN] and IETF Deterministic Networking (DetNet) [RFC8655].

2.  Provenance and Documents

   The 3rd Generation Partnership Project (3GPP) incorporates many
   companies whose business is related to cellular network operation as
   well as network equipment and device manufacturing.  All generations
   of 3GPP technologies provide scheduled wireless segments, primarily
   in licensed spectrum which is beneficial for reliability and
   availability.

   In 2016, the 3GPP started to design New Radio (NR) technology
   belonging to the fifth generation (5G) of cellular networks.  NR has
   been designed from the beginning to not only address enhanced Mobile
   Broadband (eMBB) services for consumer devices such as smart phones
   or tablets but is also tailored for future Internet of Things (IoT)
