The solution architecture

A complete IoT architecture, from sensor to decision

The DigitalWan solution links multi-measurement sensors to a monitoring platform through a self-sufficient wide-area network. MSU-SD7 slave units transmit over LoRa to the MSU-MD7 master unit, which relays the data to an MSU-SG7 gateway over LoRaWAN 868 MHz, or straight through the mobile network over LTE-M or Cat-1 bis. The MSU-XD7 and MSU-LD7 standalone units, for their part, transmit directly over LTE-M, with no gateway or master unit.

Sense

4 built-in sensors, wired in series

Every device in the range carries the same measurement components. The wireless option is identical on the slave unit and the master unit.

TMP112

Temperature

Ambient temperature and temperature inside the enclosure, from −40 to +125 °C.

LIS2DH12

Movement and shock

3-axis accelerometer: tilting, inclination, theft and vandalism.

OPT3001

Light

Detects the cover being opened and changes to darkness.

A121

60 GHz radar

Fill level, distance measurement and presence detection.

External inputs

2 channels for your existing sensors

The two channels are independent and each one can be set up as a probe or a dry contact, on the MSU-MD7 and MSU-SD7 units.

Channel 1: external probe

Remote wired sensors: temperature, level, ultrasonic and humidity, connected over I2C or PSI. J4 connector with an IP68 waterproof cable gland.

Channel 2: dry contact

On/off signals: opening, alarm, limit switch and pulse counting, with built-in interference and bounce suppression.

Detection modes

Two detection modes running at the same time

Depending on the configuration, each sensor runs two of the following detection modes, selected from the platform.

Examples in telecom chambers

Inclination

Change of orientation on three axes compared with a reference position.

Movement

Movement of the sensor, measured by the built-in accelerometer.

Vibration

Vibrations detected by the built-in accelerometer.

Infrared presence

Presence detection using infrared.

Change in light

Change in light or lighting conditions, for example when a cover is opened.

H2S gas

Detection of hydrogen sulphide.

Cable drum unwinding

Geolocated tracking of fibre optic cable deployment, metre by metre.

Connect

Redundant communication links

Two synchronised transmission technologies and an encrypted chain: the data gets through, even if one network goes down.

LoRa 868 MHz

Long-range radio link between the sensors and the master unit, with no subscription.

IP network

Ethernet or Wi-Fi to connect the gateway to the platform.

GSM / LTE-M

Mobile operator network through the built-in MFF2 eSIM.

Redundant private networks

Two transmission technologies provide active redundancy and service continuity, even if one channel fails.

Encrypted transmission

Data is synchronised across two separate technologies, encrypted end to end and aggregated on secure platforms.

Data-driven decisions

Real-time collection and analysis, assisted by artificial intelligence, to automate monitoring and react quickly to anomalies.

Interoperable and white label

The solution works with existing equipment and platforms, and is available as a white-label offering tailored to each company.

Decide

The DigitalWan platform

Monitoring, alerts and API: historical data, dashboards and decision support, available on the web, Android, iOS and macOS.

  • Dashboard

    A real-time overview of the deployment, from a web or mobile control screen.

  • Alerts and callouts

    Real-time alert notifications, with callouts triggered and followed up in the platform.

  • Device management

    Check the status of every device, choose its detection modes and update it remotely.

  • Data management

    Browse, search and export measurements as tables and charts.

  • Reports and KPIs

    Configurable weekly or monthly reports, together with key performance indicators.

  • API and integration

    Secure API keys to feed the data into your own business applications.

Frequently asked questions

Questions about the architecture

How do DigitalWan sensors communicate?

MSU-SD7 slave units transmit over LoRa to an MSU-MD7 master unit, or straight to the gateways over LoRaWAN. The master unit relays the data to an MSU-SG7 gateway over LoRaWAN 868 MHz, or straight to the platform through the mobile network over LTE-M or Cat-1 bis. The MSU-XD7 and MSU-LD7 standalone units communicate over LTE-M only, with no gateway or master unit.

Does a gateway have to be installed to use the sensors?

No. Devices fitted with an eSIM transmit over the mobile network, with no local infrastructure. The MSU-SG7 gateway is useful for large sites, areas with poor coverage or deployments with many sensors.

How many sensors can be deployed on one site?

An MSU-MD7 master unit handles up to 5 slave units, and an MSU-SG7 gateway collects master and slave units with no limit on the number of nodes.

Can the data feed our own software?

Yes. The DigitalWan platform provides an API and secure access keys to feed the measurements into your business applications.

Is the solution available as a white label?

Yes. DigitalWan is an interoperable white-label solution that adapts to the needs and constraints of each company.

Is the transmitted data secure?

Yes. The information is synchronised across two separate transmission technologies, encrypted end to end and aggregated on secure platforms.
