Connectivity : the key to a successful IoT project

For the sensor to communicate data to a platform, you need to find the right connectivity for your project. We answer several questions before choosing the connectivity:

  • What kind of data is to be transmitted (data, voice…)?
  • How often should the data be uploaded (every hour, minute, second…)?
  • Is the object battery operated or does it need to be powered?
  • Will the object move or remain fixed?
  • Where will the object be placed (difficult place, buried…) ?

Depending on the answers, we use 3 main technologies to connect an object to the internet:

Réseau GSM 3g 4g

3G and 4G

Thanks to wireless cellular networks, we can connect the sensors anywhere and anytime. We mainly use multi-operator SIM cards that connect to the best network at time T. The sensors will have automatic access to the various operators’ networks (Bouygues Télécom, Orange, SFR…). This allows you to maximize the connectivity of your sensors and to collect your data in real time.

carte sim

Transfers large amounts of data,
Roaming capacity (deployment of internationally connected objects),
Remote SIM card monitoring,
Permanent connectivity.


LoRa network 

The LoRaWAN protocol is an open protocol that allows objects to exchange data at low data rates (low data volume).  We use the network operated by for its long-range connectivity and low energy consumption. We also use and its ThingPark platform to allow customers to create their own LoRa network.


Low consumption and bidirectional,
Long distance (between 2 and 5 km in urban areas / up to 10 km in rural areas),
Ideal for an periodic emission.


WiFi network 

Thanks to – wifi network operator of the NomoTech Group – we can offer a unique wifi access service. NomoSphère takes care of installing the Wifi terminals in concerned places (cities, train stations, hospitals…).  The Wifi networks allow to connect the sensors permanently, and to send the data on our restitution platform.

Each connectivity technology has its own advantages and disadvantages. So, we take into account 6 criteria to provide you with a tailor-made service: cost, range, capacity, reliability, consumption and sensor lifetime. To have the best connectivity, we work closely with qualified partners in their field of activity.
