Abstract

   This document presents an overview of the network architecture and
   system characteristics of a typical SIGFOX Low Power Wide Area
   Network (LPWAN), which is in line with the terminology and
   specifications being defined by the ETSI ERM TG28 LTN group.  It is
   intended to be used as background information by the IETF LPWAN group
   when defining system requirements of different LPWAN technologies
   that are suitable to support common IP services.

1.  Introduction

   This document presents an overview of the network architecture and
   system characteristics of a typical SIGFOX LPWAN, which is in line
   with the terminology and specifications being defined by the ETSI ERM
   TG28 Low Throughput Networks (LTN) group [etsi_ltn].  It is intended
   to be used as background information by the IETF LPWAN group when
   defining system requirements of different LPWANs that are suitable to
   support common IP services.

   LPWAN technologies are a subset of IoT systems which specifically
   enable long range data transport (e.g. distances up to 50 km in open
   field), are capable to communicate with underground equipment, and
   require minimal power consumption.  Low throughput transmissions
   combined with advanced signal processing techniques provide highly
   effective protection against interference.

   Because of these characteristics, LPWAN systems are particularly well
   adapted for low throughput IoT traffic.  SIGFOX LPWAN autonomous
