What is the difference between IoT and embedded systems?

The rapid advancement of technology has led to a merging of boundaries between different sectors. This convergence is particularly noticeable in the realm of IoT (Internet of Things) embedded systems, where the terms "IoT" and "embedded system" are often used interchangeably. However, it's important to recognize that embedded systems and IoT are distinct concepts, even though they share some similarities.

Embedded systems have been in existence since as early as 1965 when Autonetics, a company, created a small computer for use in a missile guidance system. These embedded systems are essentially standalone devices designed with a specific, dedicated function in mind. On the other hand, an IoT embedded system is an embedded system that possesses the added capability of connecting to the internet, enabling communication with other IoT embedded systems.

In our daily lives, we are surrounded by IoT embedded systems, including devices such as set-top boxes, Point-of-Sale (POS) terminals, various medical devices, "smart" appliances like refrigerators, bicycles, fitness trackers, and even parking meters.

In the following discussion, we will delve into the intricacies of embedded systems designed for IoT devices. We will explore what defines an embedded system for IoT, its capabilities, and practical applications of embedding IoT functionality into these systems.

The key distinction between IoT (Internet of Things) and embedded systems boils down to one crucial factor: connectivity. Even an embedded system, like a pacemaker, can be transformed into an IoT embedded system when it gains the ability to communicate with the external world, such as sending heart-rate data to a central database.

Another distinguishing feature is that IoT encompasses a broader category of devices representing the interconnected world, whereas an embedded system pertains specifically to the hardware within these devices.

The fundamental difference between an embedded operating system and an IoT operating system lies in the necessity for IoT systems to support connectivity. The capability of IoT devices to network and communicate sets apart plain embedded systems from their IoT counterparts.

In every IoT scenario, there's an embedded system at its core, which is why the term "IoT embedded system" is used. Initially, there exists an embedded system, and then additional features are integrated to transform it into an IoT device.

Embedded systems can be remarkably sophisticated, such as robotic systems used in manufacturing or data warehouses. However, their function as pure embedded systems remains limited to their specific purpose until they acquire the ability to communicate and establish connectivity with other IoT embedded systems.

Therefore, the primary distinction between an embedded system and an IoT embedded system hinges on the latter's capacity for communication and connectivity.

What is the difference between the LoRaWAN wireless module and LoRa gateway wireless transmission technology?

Many individuals find it challenging to differentiate between the LoRaWAN wireless module and LoRa gateway wireless transmission technology, as well as their applications within the realm of IoT.

LoRaWAN specifically pertains to the networking protocol found within the MAC (Media Access Control) layer. In contrast, LoRa serves as a protocol within the physical layer. Although current LoRaWAN networking implementations utilize LoRa as the physical layer, it's worth noting that the LoRaWAN protocol also allows for the use of GFSK (Gaussian Frequency-Shift Keying) as the physical layer in specific frequency bands. From a network layering perspective, LoRaWAN can adopt various physical layer protocols, just as LoRa can serve as the physical layer for other networking technologies.

LoRa, as a technology, falls under the category of LPWAN (Low-Power Wide-Area Network) communication technologies. It represents an ultra-long-distance wireless transmission method based on spread spectrum technology, pioneered and promoted by Semtech in the United States. This approach revolutionizes the previous trade-off between transmission distance and power consumption, offering users a straightforward system capable of achieving extended range, prolonged battery life, and increased capacity. Consequently, it expands the capabilities of sensor networks. Currently, LoRa predominantly operates within free frequency bands globally, including 433/868/915MHz, among others.

On the other hand, LoRaWAN wireless communication stands as an open standard defining the communication protocol for LPWAN technology based on LoRa chips. LoRaWAN defines the Media Access Control (MAC) layer at the data link level and is overseen by the LoRa Alliance. It's crucial to distinguish between LoRa and LoRaWAN because companies like Link Labs utilize a proprietary MAC layer in conjunction with LoRa chips to create more advanced hybrid designs, such as Link Labs' Symphony Link.

LoRaWAN typically employs a star or star-to-star topology, which is generally considered superior to mesh networks due to advantages such as conserving battery power and extending communication range. In a star topology, messages are relayed to a central server through gateways, and each end node can transmit data to multiple gateways. These gateways then forward the data to the web server, where tasks like redundancy detection, security checks, and message scheduling are executed.

In summary, LoRa encompasses solely the link layer protocol, making it suitable for point-to-point (P2P) communication between nodes. In contrast, LoRaWAN includes the network layer, allowing data to be sent to any base station connected to a cloud platform. By connecting the appropriate antenna to its socket, the LoRaWAN module can operate at different frequencies, offering versatility in its applications.

Cellular technology, on the other hand, includes technologies like 2G, 3G, 4G (LTE), and 5G, which are used for mobile voice and data communication. Cellular networks are typically designed for high-speed data and voice communication and operate in licensed RF spectrum.

While both LoRaWAN and cellular networks enable wireless communication, they serve different purposes and operate in different frequency bands with distinct characteristics. LoRaWAN is often chosen for applications that require long-range connectivity with low power consumption, whereas cellular networks are used for more data-intensive and ubiquitous mobile communication.

How do LoRaWAN® Gateways work?

A LoRaWAN gateway has the capacity to serve multiple sets of devices concurrently, although gateways are often deployed in overlapping clusters. Devices transmit their signals as radio frequency (RF) packets, which can be received by any gateway within their range. The gateway with the strongest connection to the device will then relay the message to the cloud. Employing multiple gateways enhances network resilience in case of gateway failure.

LoRaWAN gateways can be implemented and operated within a private network controlled by a company. For instance, if you need to monitor water levels or pressure at various locations within a reservoir site, gathering data from remotely placed sensors could be a challenging, time-consuming, and costly endeavor. However, by employing LoRaWAN to wirelessly connect these sensors, data collection becomes effortless, and the information can be directly delivered to laptop and mobile applications. To achieve this, the sensor initially wirelessly transmits the data to a LoRaWAN gateway. The gateway subsequently forwards the data from the array of sensors to the cloud and, ultimately, to your application.

In certain situations, particularly in urban areas, LoRaWAN network providers may offer gateway connectivity as a service to multiple end users for a fee.

Once received by a gateway, RF signals are transformed into a format that enables faster data transfer rates. While the maximum data rate of LoRa, at 50Kb/s, suffices for device-to-device or device-to-gateway communication, it could become a bottleneck when attempting to transmit a large volume of messages to the cloud. Hence, a well-designed gateway is essential to facilitate higher data transfer rates from the gateway to the cloud.

Typically, a connection between a gateway and the cloud is established through Ethernet for its speed, but LTE and Wi-Fi are also viable options in outdoor settings.

Subsequently, the data becomes accessible in the cloud via the relevant application. Many sensors are equipped with their own applications that present the data in a user-friendly manner.
