  Requirements for IoT Services based on Visible Light Communications
                  draft-sjkoh-requirements-iot-vlc-00

Abstract

   This document describes the requirements for IoT Services based on
   Visible Light Communication (VLC) to effectively provide IoT services
   in the VLC-based networks.  This document includes the overview of
   VLC technology and the concepts of VLC-based IoT services, and the
   requirements for IoT services in the VLC-based networks.

1.  Introduction

   The VLC has been developed as a wireless communication technology
   which uses visible lights, infrared (IR), and ultra-violet (UV)
   spectrum instead of conventional RF band.  In particular, the VLC
   provides the following distinctive features: 1) non-interference to
   existing RF bands, 2) free license to use the spectrum of visible
   light, IR, and UV, and 3) VLC can be easily deployed with the
   existing LED lights.  Since the VLC is non-RF based wireless
   communication technology, it can be complementary wireless
   communication technology among the RF-based wireless communication
   technologies (mobile network, WPAN, WLAN).  These distinctive
   features of VLC will be helpful to overcome the shortcomings of the
   existing RF technologies.

1.1.  Terminology and Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14.  [RFC2119], [RFC8174] when, and only when, they appear in all
   capitals, as shown here.
