LoRaWAN private vs public network, which one to choose?

When starting an IoT project, the choice of technology and the construction of the network architecture are among the essential questions to ask. LoRaWAN technology is now one of the pillars of the IoT and has established itself as an essential element in the world of connected objects.

When choosing LoRaWAN, the key question is whether to opt for a public (or operated) network, or a private network. To help you consider your options, here’s a comparison of these two solutions to help you bring your IoT project to fruition.

What is a LoRaWAN network?

LoRaWAN (Long-Range Wide-Area Network) is a radio communication protocol designed for transmitting small amounts of data at low bit rates and is particularly well suited to connected objects. The LoRaWAN protocol belongs to the LPWAN (low power wide area network) category.

A LoRaWAN-connected object can send a message from around 1 kilometre in an urban area (containing obstacles) and 20 kilometres in a flat rural area.

This long-range network is based on proprietary LoRa modulation technology. Therefore, this technology offers an extended range, while maintaining low energy consumption, enabling battery-operated products to have autonomies of several years.

Each LoRaWAN operator has its own network and therefore its own coverage map. More than 170 operators worldwide (as of 2023) offer a LoRaWAN network in more than 162 countries.

LoRaWAN uses free frequency bands (without royalties), which reduces network operating costs. It also allows the creation of private networks covering specific areas without subscription fees.

What are the differences between LoRaWAN private vs public network?

Public network (or operated network) LoRaWAN

A public or operated LoRaWAN network is deployed and managed by telecom operators. The infrastructure is shared between users. This type of network offers vast geographical coverage for a large number of sensors.

+

Benefits

  • Extensive coverage: public networks, managed by operators such as Orange, cover vast geographical areas.

  • Easy to set up: you can quickly connect your sensors to the existing network without needing to deploy any special infrastructure.

  • Operator-managed network infrastructure: the public network is deployed and managed by a telecom operator.

  • Interoperability: LoRaWAN is a standardised and open protocol that enables devices from different manufacturers and organisations to communicate.

Disadvantages

  • Dependence on network coverage: if you are in an area with poor network coverage (e.g. a rural area or underground), the communication of your sensors will be limited.

  • Requires prior assessment: to ensure that your application works properly, it is best to assess the quality of network coverage and expected performance before deployment.

  • Business model: the business model is subscription-based. This can be costly if the number of sensors becomes large.

  • Limited control: organisations have limited control over network infrastructure and security policies.

LoRaWAN Private Network

A LoRaWAN private network is a network deployed locally, generally on a specific site (such as a company or municipality). It requires the installation of a dedicated infrastructure (including gateways and servers) belonging to the project owner.

+

Benefits

  • Total control and data security: private LoRaWAN networks offer total control over infrastructure, security policies and data management. Sensitive data remains within the boundaries of the organisation, reducing the risk of data breaches.

  • No operator subscription: once the architecture is in place, you don’t have to pay monthly or annual subscription fees.

  • Network coverage: deploying a private network can be an alternative to poor network coverage. Private networks offer predictable performance in terms of latency, reliability and coverage.

  • Customisation: private networks allow you to customise network architecture, frequency bands and deployment locations.

Disadvantages

  • Start-up infrastructure costs: you need to invest in infrastructure including gateways at the beginning of the deployment.

  • More complex maintenance and management: in a private network, you are independent and therefore responsible for maintaining and updating your infrastructure.

  • Coverage: private networks enable you to cover a restricted, specific geographical area.

Summary table: LoRaWAN private vs public network

Criteria Private network Public network
Controle Administrator has full control over network settings. Access open to all (often with payment of a fee).
Coverage Predictable, stable performance. Limited to the local area network (LAN) of the company. Extended to the whole territory. May be limited in an environment with obstacles (buildings, hills, subsoil, etc.) or depending on the number of connected devices present in the area.
Installation Requires the deployment of a specific infrastructure (sensor + gateway + server) Fast, just need to connect the sensors
Data security Total control, control of data confidentiality Operator-managed security, shared data
Cost Gateway purchase + subscription or linked licence if required Subscription per sensor
Maintenance Fast, just need to connect the sensors Managed by the public operator
Interoperability Customisable to specific needs Standardised protocol, guaranteed interoperability
Dependency Autonomous, without dependence on an external operator Dependence on the coverage and quality of the operator's network
Flexibility High, customisable architecture and frequencies Less flexible, subject to operator conditions

In conclusion, the choice between a public and a private network is specific to each project and depends on several factors. In all cases, to help you check the availability of the network (in the case of a public network architecture), or to validate the location of your gateways and sensors (in a private network), it is essential to carry out a radio-mapping study.

The comparison table below should help you make the decision that is best suited to your needs.

LoRaWAN

LoRa and LoRaWAN are related but perform different functions within wireless communication networks.

LoRaWAN is the network protocol that links the LoRa signal (sensor data) to applications. In simple terms, LoRa is the radio signal that carries the data, and LoRaWAN is the communication protocol that controls and defines how that data is communicated across the network.
