LoRa® and NB-IoT: Low-Power Wide-Area Network (LPWAN) Technologies

On the other end of the spectrum are Low-Power Wide-Area Network (LPWAN) technologies such as LoRa® (Long Range) and Narrowband IoT (NB-IoT). LoRa® uses radio communication and gateways to transmit data, while Narrowband IoT (NB-IoT) typically relies on cellular infrastructure. These technologies are designed for scenarios where devices need to send small packets of data over long distances without consuming much power. They are ideal for applications where devices are spread out, such as smart city infrastructure management, where sensors monitor everything from street lighting to waste management systems across urban areas.

Challenges of Traditional Connectivity

Despite the strengths of terrestrial connectivity in enabling real-time and remote monitoring, challenges such as signal range limitations and infrastructure requirements can impact its effectiveness, particularly in less accessible regions. In agriculture, for example, the need for constant data to monitor crop conditions necessitates a connectivity solution that can reliably cover large fields often in remote areas. Similarly, ensuring real-time tracking of goods across diverse terrains and multiple regions in logistics calls for a versatile and robust communication network.

 

Satellite Connectivity Solutions

Satellite connectivity is reshaping the landscape of IoT remote and real-time monitoring, offering a set of unique features that terrestrial networks can struggle to match. With its wide-reaching, continuous coverage that isn’t bound by the need for multiple licences or limited by geographical constraints, satellite technology delivers significant benefits in terms of coverage, reliability and scalability in the IoT ecosystem. This reliability extends to its resilience against terrestrial infrastructure disruptions and harsh weather conditions, ensuring that critical data continues to flow even in the most challenging environments.

Satellite Backhauling

Satellite backhauling represents a foundational principle of satellite connectivity. It serves as a robust solution that bridges the gap between remote sensors and the central processing hub, with the ability to effectively cover vast distances. Satellite backhauling involves collecting data from numerous sensors located in remote or hard-to-reach areas and transmitting it through a central satellite terminal, such as Hughes 4500 or 4510 MSS terminals, to a processing centre. This method proves invaluable in scenarios where terrestrial networks fall short, offering an efficient way to manage data from widespread locations reliably.

Satellite backhauling offers significant advantages in areas where there is high device density.

However, with the required investment in the terminal hardware and data transmission costs, it is not always commercially attractive when there are smaller numbers of devices and data requirements.

Direct-to-Satellite Solutions

On the frontier of satellite connectivity innovations are direct-to-satellite solutions, which enable IoT devices to communicate directly with satellites, bypassing the need for terrestrial infrastructure or central satellite terminals.

This approach is exemplified by technologies integrating satellite connectivity with LoRa® to create solutions like Maxxive IoT. This solution integrates our EM2050 module directly into the IoT device, streamlining the process of sending data directly from the source to the satellite.

The emergence of Non-Terrestrial Network (NTN) Narrowband IoT (NB-IoT) technologies will further substantiate the potential of direct-to-satellite solutions, expanding the possibilities for IoT deployments in remote areas.

Direct-to-satellite solutions are especially effective in scenarios where devices are widely distributed across remote locations and need to transmit small amounts of data infrequently. For example, this technology significantly benefits applications such as environmental monitoring in uninhabited areas, critical infrastructure management over vast regions, or asset tracking across multiple territories. When there is sparse sensor deployment, the lack of a requirement for additional infrastructure delivers a valuable cost advantage. It also supports ease of deployment and scalability. Moreover, the low-power consumption of LoRa® technology adds further cost benefits and convenience when devices are in remote or hard-to-reach areas.

Challenges of Satellite Connectivity

While satellite connectivity offers many benefits, it also comes with challenges. For example, there are the initial investment costs and infrastructure requirements for satellite backhauling. However, as explored above, innovations in direct-to-satellite solutions using technology such as LoRa® are circumventing traditional infrastructure and cost hurdles, making satellite connectivity an increasingly viable option for wide-ranging IoT remote and real-time monitoring applications, even for those with stringent budget constraints. As this technology becomes more widely adopted, we’ll see increasing evidence of the advantages it can deliver.
