LTE-M (Long-Term Evolution for Machines, ook bekend als Cat-M1)

NB-IoT (Narrowband IoT) and LTE-M (Long-Term Evolution for Machines, also known as Cat-M1) are both technologies designed for the Internet of Things (IoT) and are part of the broader ecosystem of Low Power Wide Area Networks (LPWAN). Although both technologies are aimed at connecting devices with low power requirements and limited data connections, they have some key differences in usage, performance, and applications. The key differences between NB-IoT and LTE-M are outlined below:

Simhuis ONE sim

Simhuis is the first to introduce the 2-in-1 SIM card combined into 1 SIM card.

SIM card profile 1

This profile works with a minimum of 2 providers per country; a third is certainly possible if desired. Connectivity includes Data, SMS, and Voice. There is an option to use a public fixed IP address.

SIM card profile 2

This profile is from Vodafone Netherlands and acts as a backup SIM card by default. If profile 1 is lost due to a malfunction (assuming a malfunction of the SIM card provider, causing the connectivity of KPN, Vodafone and Odido to be switched off or even completely lost), we will automatically or manually switch to a completely different profile from Vodafone (this profile (2) operates on a different server than profile 1 and they are unrelated). As a result, the chance of you having no connectivity is very rare!

Conclusion:

Both technologies are complementary and are often used in various aspects of IoT networks, depending on the specific requirements of the application.

LTE-M (Long-Term Evolution for Machines), also known as Cat-M1, is a technology specifically developed for connecting Internet of Things (IoT) devices over mobile networks. It utilizes existing LTE infrastructure and is optimized for applications that require low power consumption and reliable, slow but stable connections.

LTE-M operates on the same frequencies as standard LTE networks because it is designed to function within the same infrastructure. The exact frequencies on which LTE-M is used vary by region, but it essentially follows the LTE frequency bands. This means that LTE-M is available on both low and high frequency bands, depending on coverage and network needs.

Commonly used LTE-M frequency bands:

Low frequency bands (Sub-1 GHz)

Low frequency bands offer a wide range and better penetration into buildings. They are often used for applications in rural areas and for IoT devices that need to operate inside buildings, such as smart meters and sensors.

Center frequency bands (1-2 GHz)

Mid-frequencies offer a balance between speed and range. They are widely used in urban areas where more data capacity is needed, but also reliable coverage.

Higher frequency bands (above 2 GHz)

Higher frequencies are used less frequently for IoT applications due to their more limited range and poorer penetration into buildings. However, they are useful in densely populated urban areas where more capacity is needed.

Applications of LTE-M:

Conclusion:

LTE-M operates on the same frequencies as standard LTE, allowing it to utilize existing LTE infrastructure. The most commonly used frequencies for LTE-M are low bands such as 700 MHz, 800 MHz, and 900 MHz, because these bands offer a wider range and penetrate walls and obstacles better. In more densely populated urban areas, higher frequencies such as 1800 MHz and 1900 MHz are also used to provide additional capacity for IoT applications.

Advantage of LTE-M

The biggest advantage of LTE-M is the combination of low energy consumption, full mobility, and real-time data connectivity, making it a highly versatile solution for a wide range of IoT applications. Here is why this is such a major advantage:

LTE-M's versatility lies in its ability to support mobile devices, be energy-efficient, and process real-time data, all with a reliable connection over existing networks. This makes it ideal for both stationary and mobile IoT applications that require more than just basic data exchange.

Full Mobility

LTE-M offers full support for mobility, which means that devices can switch between cell towers without interruption. This is essential for applications such as vehicle and asset tracking, wearable devices, and health monitoring where the devices move.

Low energy consumption

Despite the mobility and higher data speeds, LTE-M offers excellent energy efficiency. Devices can last for years on batteries, thanks to features such as Power Saving Mode (PSM) and eDRX, which help minimize power consumption when the devices are not active.

Higher Data Speeds and Lower Latency

Unlike other IoT technologies such as NB-IoT, LTE-M offers higher data speeds (up to 1 Mbps) and lower latency. This makes it suitable for applications that require real-time data transfer or even voice support, such as smart wearables, security devices, and connected health devices.

Broad Coverage via Existing LTE Networks

LTE-M uses the existing LTE infrastructure, which means it offers the same coverage and reliability as 4G networks. This ensures that it works in both urban and rural areas without additional network expansions.
