Which network for which application need in the B2B IoT?

To go a step further with the opinion expressed by HIKOB CEO’s in his paper « The IoT is not limited to LoRa and Sigfox networks », the following three examples of IoT applications in the B2B field are an undeniable illustrations of the interest of broadband, low-power and extended range networks.

 

Which network for my application need?

The aim is not to confront two low-power networks but to clarify the use of each network according to the different contexts and needs. The low-speed, low-power and long range telecom network (LoRa/Sigfox) are particularly appropriate for applications based on independent and ad hoc data or remote meter reading applications, not requiring latency control nor complex data collection. The broadband, low-power and long range networks are more appropriate to meet the exchange between sensors requirements, equipment connection and handle, in real-time, a large amount of complex data.

The power of IoT resides in these three complementary proposals to meet the different market needs.

 

Collect in real-time a large amount of data to manage road traffic flows

In the city of Troyes (France), HIKOB deployed a new generation of wireless system for vehicle detection with wireless magnetometers to manage road traffic flows in two strategic points of his road network.

Through HIKOB wireless acquisition network, the system frequently collect information as road traffic volumes, speed, occupancy rate and vehicle classification… which require a very fine correlation of the large amount of data between sensors. Local and remote data processing involves to control data flow and delay with a very low latency.

HIKOB provides a bidirectional network for local data collection with controllers and field equipment, to update them and to collect in real-time their state and that of the radio link. In this context, HIKOB network provides a very accurate and coherent dating of sensors measures, a two-way exchange for local data collection, a direct connectivity with onsite controlling equipment and offers a remote update of it or radio monitoring, in real time from a remote-control center.

To equip a civil infrastructure at the scale of a stadium

In Paris, to ensure the optimal safety for more than 50.000 people, HIKOB deployed a wireless data acquisition system to monitor the ageing of one of the biggest stadium in France but also one of the oldest (1972): the Parc des Princes stadium. HIKOB radio network relies on the free 2.4 GHz ISM frequency band which offers several communication channels for HIKOB equipment’s, reinforcing the robustness of exchanges to address the risk of disturbances during the infrastructure’s exploitation particularly during events.

The frequent data collect ensures a 24/7 continuous monitoring of the stadium. The routers HIKOB LION in the HIKOB network allow to establish a multi-hop communication with an easy extension of the acquisition perimeter. The acquisition nodes HIKOB WOLF use a high-precision real-time clock that allows each network devices to be synchronized with the others and offers dating data.

An easier access to key vibratory data

As a result of a collaboration and co-development with HIKOB, ACOEM commercializes ONEPROD EAGLE, a wireless & low power system with extended-range capabilities to collect strategic vibratory data and to detect early defaults on rotating machines. Based on a proven and robust IEEE 802.15.4e protocol, this wireless solution is designed for a use in harsh industrial environments. This protocol shares the same principles as other industrial standards such as Wireless HART or ISA100.11a, including frequency hopping and time sharing mechanisms (FTDMA protocol).

It answers to a synchronization need of many and different measurement points required for a sharp monitoring. Its adapted flow rate ensures the acquisition and reception of a large amount of data, more than 4MB of data per measurement, and therefore the study of a wide spectrum of data for a smart diagnostic that goes beyond a simple point indicators’ analysis.

The use of autonomous routers makes it possible to deploy an extended radio network architecture to cover wide areas and large spaces, to improve the monitoring of isolated or inaccessible machines, in the harshest environments. The network provides a functional system where safety conditions are not met for manual measurement. The protocol thus guarantees the safety of the staff, data relevance and enables an advanced conditional maintenance of the equipment.

Broadband, long range, proven and standardized protocols in harsh industrial environment

Wireless networks are generally sought to avoid strong constraints of installation and cabling, cost reduction and their ability to address industrial spaces with difficult access.

In addition to local network solutions such as a WiFi network or Lora, Sigfox or NB-IoT remote and operated networks, standard communication protocols have been designed and are available for industrial environment: WirelessHART, ISA100.11a or IEEE 802.15.4e. They provide a strong basis for the construction of meshed networks in contexts where network reliability, data resilience, data synchronization and large amount of data collection are indisputable constraints.
