Speaking of the wireless communication technology of the Internet of Things, everyone must be familiar with LoRa, because it adopts the principle of spread spectrum modulation and a unique error correction mechanism to achieve ultra-long-distance wireless transmission. Wireless communication distance is longer.
Of course, the focus of this article is not to discuss the characteristics of LoRa, but to talk about several key core parameters in LoRa modulation.

1. Spreading Factor (SF)
LoRa spread spectrum employs multiple information chips to represent each bit of payload information. The speed at which spread information is sent is called the symbol rate (Rs), and the ratio between the chip rate and the nominal symbol rate is the spreading factor, which represents the number of symbols sent per information bit. The popular understanding is to represent a single data bit with multiple information chips.
To simplify the explanation in the digital domain, if we agree that 101110 means that the actual data bit is 1, a valid data packet such as 0xFF needs to be transmitted in the application, and the corresponding binary representation is: 1111 1111, then the information chip to be actually transmitted is:

Through the above method, the bit error rate of transmission can be reduced, thereby increasing the effective communication distance. However, when the number of transmitted information symbols is the same, the actual amount of effective data transmitted is reduced. Therefore, when other parameters are the same, The larger the SF parameter is set, the smaller the actual transmitted data rate.

LoRa spreading factor value range:

Note:
① The above table is taken from the SX127x data sheet;
② SF=6 can only be used in ImplicitHeader mode;
③ SX126x series can support SF=5
2. Modulation bandwidth BandWidth(BW)
Channel bandwidth is used to limit the frequency range allowed to pass through the current channel, which can be understood as a frequency passband.
The frequency allowed by a channel is usually 433.125MHz to 433.250MHz, and the corresponding BW=125kHz.
According to Shannon's theorem, increasing the channel bandwidth can increase the effective data rate to shorten the air delay time

Shannon's theorem
However, it can be seen from the digital sensitivity calculation formula that increasing the channel bandwidth will reduce the system sensitivity, thus shortening the wireless communication distance.
Receive sensitivity S = 10lg⁡(KTB) + NF + SNR, where B represents the channel bandwidth.
In LoRa modulation, the channel bandwidth is bilateral bandwidth (full channel bandwidth), while the BW of traditional FSK modulation refers to unilateral bandwidth or receiving bandwidth.

3. Coding Rate(CR)
In the process of LoRa communication, cyclic forward error correction technology is used internally, that is, part of the data in the actual data packet transmitted over the air is used for error correction decoding, and the ratio of the effective data length to the actual length of the air transmitted data packet is called encoding rate.
LoRa encoding rate value range and corresponding overhead ratio:

Note: The above pictures are taken from the SX127x data sheet
Based on the above, it can be seen that using the error correction algorithm will increase the link overhead and reduce the effective data transmission rate. However, due to the existence of the error correction code, the transmission has strong anti-interference ability and higher reliability.
Speaking of this, I feel that I need to go deeper, otherwise I will not be able to reflect my own level
Relationship between LoRa signal bandwidth BW, symbol rate Rs and data rate DR

Chip speed Rc:
As mentioned earlier, the bandwidth has a great relationship with the transmission rate of the signal. Here, the transmission rate of the chip is equal to the value of the bandwidth (unit Hz), that is:
Rc=BW = |BW|chips/s

Symbol rate Rs:
Each symbol has 2^SF chips, and the transmission rate of the chips is Rc, so the symbol transmission rate Rs is:
Rs= Rc/2^SF = BW/2^SF

Data transmission rate DR (or bit Rate):
DR= Rb(bits/sec) = SF * Rs * CR = SF * (BW/2^SF) * CR

4. Low Data Rate Optimization
In the cognition of many people, the core parameters of LoRa seem to be only SF, BW, and CR. The parameter value setting of Low Data Rate Optimization is easy to be ignored, but in the design process, this parameter is still very important, especially In the application process of low rate and large data packet transmission, the long-term continuous transmission of the transmitter may cause system frequency deviation and reduce the communication success rate. After enabling the Low Data Rate Optimization option, it can improve the communication robustness of LoRa under low rate conditions. sex.
The specific setting condition is that when the transmission time of a single symbol exceeds 16 milliseconds, the LowDataRateOptimize bit must be enabled, and both the transmitter and the receiver must have the same LowDataRateOptimize setting.
Take BW=500K, SF=9 as an example:

At this time RS =500kHz / 512, TS = 1 / RS = 512/500kHz= 1 ms
In this case, it is not necessary to enable Low Data Rate Optimization.
Take BW=25K, SF=10 as an example:
At this time RS =25kHz / 1024, TS = 1 / RS =1024/25kHz= 40.96 ms
In this case, Low Data Rate Optimization must be turned on.

IoT represents the fourth-generation technology that facilitates the connection and transformation of products into smart, intelligent and communicative entities. IoT has already established its footprint in various business verticals such as medical, heath care, automobile, and industrial applications. IoT empowers the collection, analysis, and transmission of information across various networks, encompassing both server and edge devices. This information can then undergo further processing and distribution to multiple inter-connected devices through cloud connectivity.

IoT Application in Oil & Gas Industry:

IoT is used in the Oil and Gas Industry for two basic reasons: First - low power design, a fundamental requirement for intrinsically safe products, Second - two-way wireless communication. These two advantages are a boon for the products used in Oil and Gas industries. The only challenge is for the product design to meet the hazardous location certification.

An intrinsic safe certification is mandatory for any device placed in hazardous locations. The certification code depends on the type of protection, zone, and the region where the product shall be installed.

In the North American and Canadian markets, the area classification is done in three classes:

Class I: Location where flammable gases and vapors are present.

Class II: Location where combustible dust is present.

Class III: Location where flying is present.

The hazardous area is further divided into two divisions, based upon the probability that a dangerous fuel to air mixture will occur or not.

Dvision-1: Location is where there is a high probability (by underwriting standards) that an explosive concentration of gas or vapor is present during normal operation of the plant.

Division-2: Location is where there is a very low probability that the flammable material is present in the explosive concentration during normal operation of the plant; so, an explosive concentration is expected only in case of a failure of the plant containment system.

The GROUP is also one of the meaningful nomenclatures of the hazardous area terms.

The four gas groups were created so that electrical equipment intended to be used in hazardous (classified) locations could be rated for families of gases and vapors and tested with a designated worst-case gas/air mixture to cover the entire group.

The temperature class definitions are used to designate the maximum operating temperatures on the surface of the equipment, which should not exceed the ignition temperature of the surrounding atmosphere.

Areas classified per NEC Article 505 are divided into three zones based on the probability of an ignitable concentration being present, rather than into two divisions as per NEC article 501. Areas that would be classified division 1 are further divided into zone 0 and zone 1.  A zone 0 area is more likely to contain an ignitable atmosphere than zone 1 area. Division 2 and zone 2 areas are essentially equivalent.

Zone-0: Presence of ignitable concentration of combustible gases and vapors continuously, or for long periods of time.

Zone-1: Intermittent hazard may be present.

Zone-2: Hazard will be present under abnormal conditions.

IoT-based products can be designed for various applications, a few of them are listed below:

1. Temperature Sensor
2. Pressure Monitoring
3. Gas Monitoring
4. Flow Monitoring

A typical block diagram of the IoT application is shown below:

Figure 1: IOT Block Diagram

An IoT product might consist of a battery as a power source or can be powered externally from either 9V ~ 36V DC supply available in the process control applications or 110/230Vac input.

The microcontroller can be selected based on the applications, power consumption, and the peripheral requirements. The microcontroller converts the analog signal to digital and based on the configuration can send the data on wired/wireless to the remote station. Analog signal conditioning stands as a pivotal component of the product, bridging the connection between the sensor and facilitating the conversion of analog signals for compatibility with the microcontroller. The Bluetooth interface suggested in the example is due to its wide acceptance and low power consumption. The wireless interface depends on the end-application of the product.

Electronics Design Consideration

The electronics design of an IoT product for a hazardous location is very complex and needs a careful selection of the architecture and base components as compared to the IoT developed for commercial applications. In case the IoT is for a hazardous location, the product must be intrinsically safe and should not cause an explosion under fault conditions. The product architecture should be designed considering various mechanical, and electronics requirements as defined in the IEC 60079 standards, certification requirements and the functional specifications.

Power Source: This is one of the main elements in an IoT-based product. Battery selection should meet the overall power budget of the product, followed by the battery lifetime. In case of intrinsic safety, special consideration is required for where the battery in charged. IEC 60079-11 clause 7.4 provide details for the type of battery and its construction details. Separation distance from the battery and electrical interface should be done as per Table-5 of IEC 60079-11. If the battery is used in the compartment, sufficient ventilation must be provided to ensure that no dangerous gas accumulation occurs during discharge or inactivity periods. In scenarios where IoT operates on DC power sources such as 9~36Vdc (nominal 24Vdc), the selection of power supply barrier protection becomes a critical consideration, particularly when catering to intrinsic safety norms. This necessitates a thorough analysis of the product’s prerequisites and the mandatory certifications. Adding to the complexity is the existence of IoT devices functioning on 230Vac, demands intrinsic safe calculations and certifications aligned with Um = 250V.

Microcontroller: Its central processing unit of the IoT product. The architecture of the microcontroller, power, and clock frequency processing must be carefully selected for a particular application. The Analog to Digital Conversion (ADC) part of the microcontroller should be selected based on the required accuracy, update rate, and resolution. Microcontroller should have enough sleep modes so that the power is optimally utilized for IoT applications and should have sufficient memory/peripheral interface to meet the product specifications.

Analog Signal Conditioning: The front-end block should meet the intrinsic safe requirements as per the IEC 60079 standards and should also protect the product from EMI-EMC testing. Barrier circuit should provide enough isolation for meeting the spark-gap ignition requirements and impedance requirement of the transducer. Also, along with the safety requirements, the designer should ensure that extracted sensor signal is not degraded from the excessive noise present in outside environment. All the sensors used for collecting data from the process parameters to the signal conditioning block must be certified for the particular zone.

Wireless Communications: There are various wireless options available for sending data from the IoT product to the sensor such as (6LOWPAN, ZigBEE, ZWave, Bluetooth, Wi-Fi, Wireless HART). Selection of a particular wireless interface requires knowledge of end application, RF-power, antenna, and protocol. Selection of the interface for a particular IoT application should be done keeping these basic things in mind:

1. The amount of data to be shared to the server.
2. RF power.
3. Power consumed for each bit of data transferred.
4. Update rate of the data and distance of communication.
5. Security of data.

In case of intrinsic safe applications, it’s important to note that the use of certified modules does not directly confer suitability for deployment in hazardous locations. The product must undergo fresh testing within an intrinsic safe lab to assess both quantifiable and non-quantifiable ffaults, along with spark testing. or the countable and non-countable faults and spark testing. The RF power transmitted from the devices should be limited as per Table-1x of IEC 60079-0.

Conclusion

When building IoT solutions for hazardous locations, special conditions relating to creepage and clearance, encapsulation, and separation distance must be carefully considered. Also, when battery and RF signals are used, it’s expected the designer should be aware of the applicable standards and limitation of these standards for such products.

It seems like everything in our lives is now connected, from TVs to fridges to doorbells to fitness mirrors. Recent research found there are an average of 15 smart devices per household, up 25% from 2020, with “power users” having as many as 34. And these smart products are often a bad actor's prime target due to lax security. It only takes one vulnerability to become an entry point for threat actors to access the entire home network. In 2021 cyberattacks on IoT devices more than doubled from 2020.

With the surging volume of IoT products and cyberattacks, consumers are increasingly vulnerable to security breaches. Over the past few years, there has been a steady stream of security flaws, from hacked baby monitors with strangers spying or talking to kids to 600,000 GPS trackers manufactured in China and shipped globally with various vulnerabilities, including a default password of 123456. Making the situation worse: these devices were helping parents track their children.

Security as a Best-Effort or Worse, an Afterthought

A lot of time and money is invested in the features and functionality of smart products. However, in the rush to capitalize on consumer interest, security is often woefully neglected. The devices are vulnerable due to limited computing resources, lack of security features, and the reliance on internet connectivity. With many, the software is not updated frequently to address emerging threats like malware, or the product is secured with a default password.

These inadequate security practices put consumers in a risky situation as hackers can easily access the home network and carry out various nefarious activities, including spying on the house, spoofing the tracker’s location, intercepting emergency calls, or obtaining personal identification information to commit fraud.

Due to the lax policies, there are a range of common vulnerabilities spanning:

• Passwords: Password reuse coupled with weak or default credentials all make it fairly easy for bad actors to gain unauthorized access.
• Encryption: If data is not encrypted or it’s out of date when it’s transmitted between the IoT device and the network, it makes it easy to access without authorization.
• Patches: If manufacturers don’t regularly update and patch flaws, this leaves the solution at the mercy of hackers to exploit.
• Privacy: Some products collect more data than needed or share data without consent, which can lead to breaches.
• Apps: Many solutions, like smart thermostats, have accompanying apps to control and configure them. These can also have security flaws, such as poor or insecure data storage or authentication mechanisms.
• Firmware checks: Without these, attackers can modify firmware and potentially take control or steal sensitive data. For example, Bluetooth protocol vulnerabilities have been the source of several high-profile breaches involving IoT devices.
• Network protocols: Some communicate using weak or outdated network protocols that make it easy for bad actors to circumvent.
• Physical security: If an attacker gains access to the physical product, this can lead to data loss.

IoT devices must be tested to ensure vulnerabilities are found and fixed before they’re made available to purchase. It's clear that the status quo is not working. With consumers continuing to add smart products, industry regulators and government action is required to help address the seismic problem.

State of Regulation

Some progress has been made, including regulation passed in California to ensure that IoT manufacturers equip their products with some basic security features out of the box. In addition, the National Institute of Standards and Technology (NIST) laid out detailed recommendations for the labeling of consumer devices.

This has led to the White House announcing the Cyber Trust Mark IoT labeling program. To obtain the certificate, each consumer IoT device must pass a standardized set of security vulnerability tests that reflect the NIST recommendations for parameters like encryption and data protection. This is an important step to address cyber risks and build consumer confidence that they can trust intelligent products. In addition, the initiative provides a common framework for manufacturers to standardize and scale IoT security with defined tests to ensure each model meets the required benchmarks. The program is modeled on the Energy Star rating system for efficient household appliances.

With the label backed by a trusted set of security vulnerability tests, consumers can quickly and easily update the security on their IoT devices by scanning a QR code. This addresses a fatal flaw with many, the lack of software updates and patches, and it marks the first national cybersecurity specification to be introduced. In addition, it will provide visibility about the types of data the device collects and how it's used.

The Future is Connected

Connected solutions are reshaping the world and with the proliferation of IoT devices showing no sign of easing, cyber risks will continue to escalate. And as Anne Neuberger, Deputy National Security Advisor for Cyber and Emerging Technologies, stated, "The U.S. Cyber Trust Mark will give consumers a way to know if the smart devices they're purchasing are secure, and give companies a label to show their products meet cybersecurity standards. …..making our homes, classrooms, and workplaces safer and less vulnerable to cyberattacks."

Adaptive Systems and Models at Runtime (ASMR) refers to a field of study and a set of techniques that enable software systems to dynamically adapt their behavior and structure in response to changing conditions or requirements at runtime. ASMR focuses on building systems that can monitor their own execution, assess their performance, and make appropriate adjustments to improve their behavior or meet desired objectives. 

Traditional software systems are typically designed and implemented based on a predefined set of assumptions and requirements. However, in many real-world scenarios, these assumptions may not hold true at all times. System behavior can be affected by various factors such as changes in user needs, environmental conditions, resource availability, or even the emergence of new system components or services. ASMR aims to address these challenges by providing mechanisms for systems to continuously monitor and analyze their runtime context and adapt accordingly.

ASMR involves the use of models that capture the system's behavior, performance, and relevant contextual information. These models can be used to reason about the system's current state, predict future states, and guide decision-making processes. By leveraging these models, adaptive systems can autonomously adjust their configuration, allocate resources, select alternative strategies, or reconfigure their structure to optimize performance, maintain stability, or achieve desired goals. 

The adaptation mechanisms employed in ASMR can vary depending on the specific system and its requirements. Some common techniques used in ASMR include dynamic reconfiguration, runtime verification and monitoring, machine learning, control theory, and feedback loops. These techniques enable systems to monitor their own behavior, detect anomalies or deviations from desired properties, and take corrective actions to maintain or improve system performance.

The application domains of ASMR are broad and can range from embedded systems and robotics to cloud computing and self-adaptive software. ASMR techniques have been employed in areas such as autonomic computing, cyber-physical systems, intelligent transportation systems, and software-defined networking, among others. 

In the context of manufacturing, ASMR can play a significant role in improving operational efficiency, productivity, and responsiveness. ASMR techniques can be applied to various aspects of manufacturing systems, including production processes, supply chain management, quality control, and equipment maintenance. Here are a few examples of how ASMR can be utilized in manufacturing:

Production Process Optimization: ASMR can enable manufacturing systems to dynamically adjust their production processes based on real-time data and feedback. By monitoring factors such as machine performance, energy consumption, product quality, and resource availability, adaptive models can optimize process parameters, sequence operations, and allocate resources to maximize productivity and minimize waste.

Supply Chain Adaptation: Manufacturing systems are often part of complex supply chains that involve multiple stakeholders and dependencies. ASMR can help in dynamically adapting supply chain operations based on changing conditions such as material availability, demand fluctuations, and transportation disruptions. By continuously monitoring the supply chain status and utilizing predictive models, adaptive systems can make informed decisions regarding inventory management, order fulfillment, and distribution strategies.

Quality Control and Defect Detection: ASMR techniques can be applied to real-time quality control in manufacturing processes. Adaptive models can learn from historical data and identify patterns related to product defects or deviations from quality standards. By analyzing sensor data, machine learning algorithms can detect anomalies, trigger alerts, and even adjust process parameters to prevent or minimize defects during production.

Equipment Maintenance and Predictive Maintenance: Adaptive systems can continuously monitor the health and performance of manufacturing equipment. By collecting sensor data, analyzing historical patterns, and utilizing machine learning algorithms, ASMR can enable predictive maintenance strategies. Equipment condition monitoring, failure prediction, and proactive maintenance scheduling can help minimize unplanned downtime, reduce maintenance costs, and optimize equipment utilization. 

Agile Manufacturing and Customization: ASMR can support agile manufacturing approaches by enabling rapid reconfiguration of production systems. Adaptive models can facilitate flexible scheduling, resource allocation, and process customization to quickly respond to changing customer demands or market trends. By dynamically adapting manufacturing systems, companies can achieve faster product introductions, shorter lead times, and improved customer satisfaction.

By enabling systems to monitor and adapt themselves, ASMR techniques contribute to the development of more flexible, robust, and self-aware software systems with many positive applications in manufacturing.
