Optimized for stationary devices transmitting small amounts of data over long periods. It is perfect for smart meters and environmental sensors due to deep indoor penetration, long battery life and cost-effective deployments.Wi-Fi connectivity
Perfect for local networks requiring fast, efficient data transfer. Widely used in smart homes and offices.LoRaWAN technology
Designed for low-power, long-range communication, perfect for rural applications like environmental monitoring.Sigfox
A low-power, long-range technology that’s cost-effective for small data transmissions, such as asset tracking and environmental monitoring.Ethernet connectivity
High-speed, reliable connections for stationary devices in industrial and commercial settings.
Each connectivity type has unique advantages and specific use cases, influenced by factors such as latency, coverage, power consumption and data transmission needs.
Why use multi-network connectivity for IoT devices?
Multi-network connectivity ensures that IoT devices remain connected, even if one network fails. This redundancy is critical for applications where continuous operation is essential, such as fleet management, where connectivity loss can lead to operational inefficiencies and increased risks.
Benefits of multi-network connectivity:

By selecting the best available network, multi-network SIMs minimize latency for faster and more reliable communication.Enhanced security:
Switching between networks based on security needs adds extra layers of protection, reducing data breach risks.Flexibility:
Automatically connects to the best-performing network, optimizing cost, performance and coverage.
How to Compare IoT Connectivity Solutions
When choosing the right IoT connectivity solution, it's crucial to evaluate the factors that will directly impact the performance, scalability, and cost-effectiveness of your IoT devices. Below are the key attributes to consider:
1. Coverage
Coverage refers to the availability and reach of the connectivity network. It's important to ensure that the network type you choose will cover the regions where you plan to deploy your IoT devices. Below are the key attributes to consider:
NB-IoT: Great for remote and rural locations.
LTE-M: Ideal for both urban and rural coverage, with excellent mobility support.
LoRaWAN: Excellent for long-range, rural environments.
Wi-Fi & Ethernet: Limited to local areas with existing infrastructure.
2. Bandwidth
Bandwidth is the amount of data the network can handle per second. It’s essential to choose a solution that can support the volume and types of transmissions your devices require. Below are the key attributes to consider:
LTE-M & Wi-Fi: High bandwidth, suitable for applications like video streaming or real-time monitoring.
NB-IoT & Sigfox: Lower bandwidth, perfect for applications with small, infrequent data transmissions like environmental sensors or asset tracking.
3. Power Consumption
Power consumption indicates how much energy your IoT devices will need while transmitting or receiving data. This is especially crucial for battery-powered devices that need to run for extended periods without recharging.
Below are the key attributes to consider:
NB-IoT & LoRaWAN: Extremely low power consumption, making them ideal for devices that need to last years without battery replacement.
Sigfox: Also low power, suited for infrequent transmissions.
LTE-M: Moderate power consumption, ideal for mobile applications and wearable devices.
Wi-Fi: Typically higher power consumption, making it less suitable for devices in remote areas.
4. Cost
Cost includes both the upfront expenses for setting up the connectivity infrastructure and the ongoing cost of data transmission. Consider whether you'll need to build and maintain your own infrastructure, or if you're relying on a third-party network provider.
Below are the key attributes to consider:
Sigfox & LoRaWAN: Generally cost-effective due to low infrastructure requirements.
NB-IoT & LTE-M: Slightly more expensive but offer more robust features and better coverage.
Wi-Fi & Ethernet: Can be more expensive for larger deployments, especially if existing infrastructure needs to be upgraded.
5. Data Throughput
Data throughput refers to the rate at which data can be transmitted or received. Ensure that the network can support the capabilities your application needs.
Below are the key attributes to consider:
LTE-M & Wi-Fi: High throughput, suitable for applications requiring large amounts of data.
NB-IoT & LoRaWAN: Lower throughput, best suited for low data transmission needs.
6. Mobility
Mobility is the ability of IoT devices to operate while moving. For certain applications, like vehicle or fleet tracking, mobility is essential.
Below are the key attributes to consider:
LTE-M: Excellent mobility support, ideal for applications requiring movement, such as tracking vehicles or assets in transit.
NB-IoT: Limited mobility support, better suited for stationary devices.
LoRaWAN & Sigfox: Mobility depends on specific network setups, typically used for long-range, stationary devices.
7. Latency
Latency refers to the time delay between sending and receiving data. For real-time applications like fleet management, low latency is critical.
Below are the key attributes to consider:
LTE-M & Wi-Fi: Low latency, ensuring near-instant communication.
NB-IoT & LoRaWAN: Higher latency, which might be acceptable for applications that don’t require real-time updates.
8. Indoor Coverage
Indoor coverage describes how well the network signal can travel indoors or underground, which is important for devices placed in challenging environments like basements or warehouses.
Below are the key attributes to consider:
NB-IoT: Excellent indoor coverage, ideal for devices in challenging environments.
LTE-M: Good indoor coverage, but may not reach very deep indoor areas in some cases.
Wi-Fi & Ethernet: Generally good for indoor coverage, but signal strength can degrade over large distances or through thick walls.
9. Security
Security refers to the protection of the network and data from unauthorized access and misuse. In industries like healthcare or finance, robust security is essential.
Below are the key attributes to consider:
LTE-M & NB-IoT: Both offer strong security features like encryption and secure authentication.
Wi-Fi & Ethernet: Security depends on network setup, but they can be vulnerable if not properly configured.
LoRaWAN & Sigfox: Provide adequate security but may not have the same level of protection as cellular networks.
