Context

In a fast-growing IoT market, with a value of 1500 B$ in 2027, i.e. +24.9% CAGR per year on average, the increased amount of data to be exchanged (in both directions) and the introduction of new applications raise the question of the use of the ISM band rather than the 4G and 5G technologies.

The current challenge is to meet the needs of applications that require access to reliable radio communication, enabling updates, the sending of security patches or the uploading of data, all while maintaining low energy consumption with a significant communication range.

Technology

The innovation is based on the use of the synchronous averaging technics to increase the equivalent signal energy without increasing the power. This signal processing increases the sensitivity and consequently the range at low power. The system is very suitable for long range, low power, and low data rate applications.

Advantages

The sensitivity improvement system is applicable to all communication system.

It can be implemented in software or as a hardware dedicated bloc (FPGA or ASIC).

The system is fully compatible with the legacy modulation techniques and any RF module.

Enhanced IoT RF booster co-processor gives the supplier of IoT network services a wider choice of frequency band to be used, especially those of very limited power (5mW) but with a longer signal occupancy time. This makes it possible to increase the communication distance and have bidirectional communications.

The certified results obtained on a test bench with the first prototype showed a gain of 10 dB, equivalent to increasing the communication distance in free space by 4. (Without any changes in the receiver architecture).

State of progress

  • Development of a test system
  • Development of an industrial prototype (alpha version)
  • This innovation is protected by two patents.

Applications

Applications that require security, e.g. in a dense area when the cellular networks are saturated.

Alternative application to the cellular networks for sending data over long distances, for example in an isolated area.

Alternative application to the cellular network and Wi-Fi to carry out updates of firmware and remote maintenance.

The system is very suitable for following application in particular:

  • Localisation and asset tracking
  • Supply chaine
  • Smart building / smart home
  • Smart-office equipment’s
