We’ll take into account your needs, your uses, and the target environment, and together we’ll define the network solution and operator that best meet your expectations.
When choosing between NB-IoT and LTE-M1 for IoT sensor applications, it’s crucial to consider the specific requirements of each project. Here are some key points to consider for a more detailed comparison:
Battery life is a crucial factor for IoT sensors, as they are usually powered by limited energy sources, such as batteries or rechargeable batteries. NB-IoT features low power consumption, enabling extended battery life for IoT sensors. This makes it an ideal solution for applications where sensors are deployed in hard-to-reach or low-maintenance locations. Although LTE-M1 consumes slightly more energy than NB-IoT, it is still more economical than traditional cellular technologies, offering sufficient battery life for many IoT applications.
Latency, i.e. the delay between sending a request and receiving a response, is an important aspect in IoT applications. LTE-M1 offers better latency than NB-IoT, meaning IoT devices can communicate faster and get real-time responses. This can be essential for applications such as security systems or connected medical devices, where fast responsiveness is crucial. What’s more, LTE-M1 supports bidirectional communication, enabling IoT sensors to send information and updates in real-time, in addition to receiving commands. NB-IoT, on the other hand, is optimized for one-way communication, which may be sufficient for certain IoT applications that do not require real-time feedback.
Data throughput is an essential factor to consider, depending on the needs of your IoT application. If your application requires sporadic, low-rate data transmission, NB-IoT is an appropriate solution. For example, sensors used in environmental monitoring or meter reading applications can make do with low data rates. On the other hand, if your application involves larger data transfers and more information-rich communication, LTE-M1 offers higher data rates, suitable for applications such as vehicle tracking or video surveillance systems.
LTE-M offers higher throughput and lower latency than NB-IoT, making this technology generally more expensive. It is therefore essential to carefully assess your company’s specific needs to find the most suitable and cost-effective solution.
The mobility of your connected object is a key factor to consider when choosing your IoT connectivity. For example, a connected car requires a ubiquitous network, while predictive maintenance in a production unit may be satisfied with a local network.
Roaming: agreements between operators enabling the use of the network in different countries, including mobility and handover.
Security: includes authentication on the network (verification of access rights) and security protocols respected.
FOTA / Acknowledgement: includes “Firmware Over-The-Air” remote update capabilities and confirmation that messages have been sent and received.
Main parameters to consider when choosing the most suitable LPWAN network:
The market for cellular (NB-IoT, LTE-M) and non-cellular (Lora, Sigfox, etc.) LPWAN networks have grown strongly over the past 2 years. What’s more, NB-IoT and LTE-M technologies account for almost 60% of the installed base worldwide.
Adeunis cellular sensors can be configured for NB-IoT and LTE-M networks, as required. These networks cover many countries around the world.
NB-IoT is a long-range connectivity technology specifically designed for IoT applications requiring low power consumption and low data rate connectivity. Thanks to its narrow bandwidth, it offers excellent signal penetration through obstacles such as buildings and underground areas. NB-IoT is ideally suited to IoT sensors requiring extended battery life and reliable connectivity over long distances.
It is a sub-category of LTE (4G) that relies on existing 4G networks that are licensed and operated by operators. The NB-IoT solution is halfway between Sigfox, Lora, and LTE-M networks.
LTE-M1, also known as LTE-Cat-M1, is a cellular network technology suitable for IoT applications. It offers higher data rates than NB-IoT, while maintaining low power consumption. LTE-M1 supports applications requiring bi-directional communication and higher data transfer rates, such as vehicle security and tracking systems. In addition, LTE-M1 offers better latency than NB-IoT, which is crucial for IoT applications requiring real-time responses.
