SIGFOX are creating a cellular style network that provides a tailor-made solution for low-throughput Internet of Things (IoT) and M2M applications using ultra-narrow band (UNB technology).

For a host of applications from smart meters to control nodes that need connectivity over long ranges, until recently it has only been possible by using a cellular connection. This option has several disadvantages because cellular phone systems are focused on voice and high data rates. They are NOT suited to low data rate connections as the radio interface is complex and this adds cost and power consumption – too much for most M2M / IoT applications.

The SIGFOX network is aimed at providing connectivity for a variety of applications and users. It is not aimed at one area, but at being for general use by a variety of different types of users. The SIGFOX network performance is characterised by the following:

  • Up to 140 messages per object per day
  • Payload size for each message is 12 bytes
  • Wireless throughput up to 100 bits per second

SIGFOX M2M application areas

The SIGFOX network and technology is aimed at the low cost machine to machine application areas where wide area coverage is required. There are a number of applications that need this form of low cost wireless communications technology. Areas where the SIGFOX network may be used include:

  • Home automation and consumer goods
  • Energy related communications – in particular smart metering & AMR
  • Healthcare – in particular the eHealth
  • Remote monitoring and control
  • Security

APC-Hero are promoting SIGFOX with Adeunis RF.                                                                                        Adeunis RF are official partners of SIGFOX and have what is said by SIGFOX engineers to be “the best SIGFOX ready module, available on the market”.  The ARF Si868 “Class 0”certified module (ARF7644AA), is ready to use on the upcoming SIGFOX network with a maximum range of 15km LOS.  Adeunis RF also provide a SIGFOX Demonstration Terminal (ARF8075AA) with inbuilt sensors (GPS, accelerometer and temperature) and comes with credit for 140 frame transmission per day for the first year of operation. Therefore this unit is perfect for testing and validation of your application on the SIGFOX network.
