When we fast forward to year 2024, technology still occupies the center stage as the cause of change that is taking place in industries, companies, and even our daily existence. The most revolutionary of them is Internet of Things (IoT). Its networks define IoT, but what is an IoT network, and why is it so important? In this blog, you will learn what IoT networks are, the various categories of uses, and the considerations when choosing an IoT network.
What Is an IoT Network?
An IoT network is the very central to the Internet of Things and is the connectivity of IoT devices, sensors, software, and systems. But what does an IoT network mean? In other words, it is a network that allows IoT devices to interface with the Internet or other devices for the exchange of information. This connectivity is the most crucial in IoT systems since it offers the integration, functionality, and delivery of information at the right time.
IoT networks are created with the assistance of various communication technologies like wireless fidelity (Wi-Fi), Bluetooth, Zigbee, and cellular technology. These networks are designed to fulfill the specifications of IoT devices for example low power, long range and many to many topologies.
How Does an IoT Network Function?
To understand how IoT networks function, it’s necessary to break down the process into 4 key components:
IoT Sensors – Data Collection
Sensors are the core of any IoT network. These sensors acquire information from the physical context, such as temperature, humidity, motion, or light. The information collected by these sensors is the basis of IoT networks and contains the necessary information for further analysis and decision-making.
IoT Connectivity – Data Transmission
Once the data has been collected, it has to be taken to a central place where it will be analyzed. This transmission is made possible by connectivity, which is through the use of IoT connectivity as a mode of connectivity. Wi-Fi, Bluetooth, and cellular networks are some of the technologies used to transfer data in an IoT network. This connectivity is essential for the proper functioning of IoT devices and their capacity to communicate with other devices and networks.
IoT Processing – Data Processing
Data that has been transmitted must then undergo analysis to be able to derive useful information from it. IoT computation refers to the analysis of the data that is gathered and the subsequent decision-making process that is done through the use of software and algorithms. This step is important in converting the raw data into useful information for automating the processes and improving the decisions that are made.
IoT Interface – Data Sending
Last of all the data is passed to the user interfaces or other systems for further processing. This could mean sending notifications, invoking responses, or even presenting data on a screen. The IoT interface is the link between the data and the users, such that they can get to interact with the IoT system and make the right decisions.
Why are IoT Networks Important?
The IoT networks are essential in the present day’s technology for the following reasons. First, they enable the establishment of links between devices and systems that may optimize work flow, productivity and decision-making processes. For instance, in smart cities, IoT networks control traffic lights, sensors, and cameras to enhance traffic flow and minimize congestion.
Second, IoT networks allow for real-time monitoring and control, which implies that changes can be made and the processes can be optimized. In healthcare for instance, IoT networks help in tracking patient’s health with an aim of acquiring their health data periodically.
Last but not the least, IoT networks encourage innovation through creation of new products and services that are based on the use of connected devices.In home automation to the industrial uses, IoT networks are the foundations of the future technologies.
4 Categories of IoT Networks
IoT is the connection of millions of devices, and all these millions of devices use different network types to perform optimally. For example, if the aim of the application is to monitor crops and livestock, for example, then the type of network that is used is critical. Here’s a look at the four main categories of IoT networks: A brief description of four primary categories of IoT network is provided below.
Cellular Networks (4G, 5G)
Due to the high coverage and data rate, the cellular networks that were originally developed for mobile communications have become an essential part of IoT. Key features include:
- High Bandwidth: Cellular networks have high throughput and are ideal for use in applications such as live video surveillance and self-driving cars.
- Widespread Coverage: These networks are very large in coverage and are suitable for smart city solutions such as traffic, logistics such as fleet and industrial IoT such as remote equipment.
- Low Latency (especially with 5G): The low latency of 5G is important for applications where timing is critical, including tele-surgery, self-driving cars and other essential manufacturing operations.
LPWAN (Low Power Wide Area Network)
LPWANs are meant for devices that must have a long battery life and a large coverage area compared to the data rate.
- Low Power Consumption: LPWAN devices have a very low power consumption and the battery can last up to years, this is suitable in the following applications:- Environmental monitoring for example in farming where soil sensors are used, asset tracking.
- Long-Range Connectivity: Some of the LPWAN technologies that include the LoRaWAN and Sigfox has a range of up to 10 km in the rural areas making it suitable for smart farming and city sensor networks.
- Cost-Effective Deployment: This technology is relatively cost efficient when compared to other technologies; thus suitable for massive applications in which data rates are low.
Local Area Networks (LAN) / Personal Area Networks (PAN)
LAN and PAN technologies are used in an effort to join the devices in a short range within homes, offices, or factories. Common examples include:
- Wi-Fi: It provides a fast connection of Internet for smart homes including setting temperatures, security cameras, and office.
- Bluetooth: Bluetooth is defined by low power consumption and a small coverage area of connectivity. It is also applied to wearables (fitness trackers) and smart home gadgets.
- Zigbee: Zigbee is a low power solution used in home automation and industries; Zigbee also supports mesh network that allows the devices to communicate as well as act as a relay to other devices.
Mesh Protocols
Mesh networks are becoming increasingly popular because of their distributed topology, which improves dependability and scalability. They feature:
- Decentralized Communication: Every device (node) can forward data to other devices and can recover if one of the nodes is down.
- Scalability: The network is more robust when more devices are connected, and it is appropriate for applications such as smart lighting systems and large industrial complexes.
- Reliability: Mesh networks are not particularly sensitive to single points of failure, which is a key consideration for applications such as smart buildings and industrial automation.
IoT Network Samples: Devices and Usage Scenarios
To better understand the applications of IoT networks, let’s explore some real-world examples across different environments. Now let us look at some of the examples of IoT networks in different environments to get a clearer picture of their use in everyday life:
Farm
In the field of agriculture, IoT networks are very useful in precision farming. Various devices installed in the farm are used to monitor the moisture content, temperature and health of crops in the farm. This information is relayed to a central system where it is processed to enhance irrigation, fertilization and pest control hence enhancing crop yields and reducing wastage of resources.
Tunnel
In tunnel monitoring, IoT networks offer safety and management of transport systems in tunnels. The condition of the air, temperature, and structural health of the building are detected and transmitted in real-time to the control centers. This makes it possible to address any concerns as and when they arise for example; inadequate ventilation or structural failure that may compromise the lives of the passengers and workers.
Hospital
Hospitals use IoT networks to improve the quality of services they offer and to optimize their functioning. Smart wearables, for example, health monitoring devices and smart beds, gather data on the patient’s vital signs and movements respectively, and this data is analyzed to identify any signs of health complications. This real-time monitoring helps in early intervention, and hence, the patients get better results while the burden on the health care staff is also reduced.
Warehouse and Factory
In industrial applications, it is used to enhance supply chain, storage, and manufacturing procedures. For instance, IoT sensors track the position and state of objects in a warehouse to facilitate proper stocking and reduce damage or loss. In factories, IoT devices are employed to monitor the efficiency of different machines and anticipate when they should be repaired. Hence, the machines are offline for a shorter time.
Office and Workplace
IoT networks are revolutionizing the contemporary working environment through intelligent building systems. Smart devices in office such as lights, air conditioning, and security cameras can be managed from a distance, using energy and improving security. IoT networks also help collaborate by integrating office appliances like printers, projectors, and other equipment into a system.
How to Select the Right IoT Network
Selecting the right IoT network is very important in the deployment of IoT. The decision is made based on the cost, the available bandwidth, energy consumption and coverage. Measuring these parameters is important in order to make sure that your network is optimized and can support your needs.
Cost considerations
- Initial Setup Costs: These include gateways and routers, among others. LPWAN networks (for example, LoRaWAN, Sigfox) are cheap for massive connections with the least amount of infrastructure.
- Operational Costs: Cellular networks need continuous data subscriptions, which are expensive for high data utilization. On the other hand, mesh networks and LAN/PAN have relatively low operational costs as compared to the other networks.
- Device Costs: Cellular-enabled devices are usually more costly than Wi-Fi or Zigbee devices, but the latter has a restricted range.
Bandwidth
Matching your bandwidth needs with the network is essential:
- High Bandwidth Applications: For such applications that involve large amounts of data such as video streaming, real-time analysis, cellular (4G/5G) or Wi-Fi networks are appropriate.
- Low Bandwidth Applications: LPWAN technologies such as LoRaWAN and Sigfox are ideal for low data density applications such as environmental monitoring and asset tracking.
- Latency Considerations: When it comes to applications where response time is crucial, for instance, self-driving cars, 5G is used. Higher latency networks such as LPWANs are suitable for non-real-time applications.
Energy Consumption
Power efficiency is key for battery-powered devices:
- Battery Life Considerations: LPWAN technologies are developed for long battery life to enable devices to work in remote areas. Mesh networks are also cost-effective in terms of energy consumption for those that need to run continuously.
- Energy vs. Performance Trade-off:High bandwidth technology such as Wi-Fi and cellular are more power hungry as compared to low power technology and hence are not suitable for devices that require longer battery life.
- Sleep Modes and Duty Cycles: LPWAN networks may also have low-power protocols that are crucial for devices that send data sparingly.
Coverage
Your required coverage area will influence the network choice: Your required coverage area will influence the network choice:
- Wide-Area Coverage: For large areas such as smart cities or farms, there is broad coverage in cellular networks and LPWAN. It is important to note that LPWANs are well-suited for rural areas.
- Localized Coverage: For closed environments such as homes or factories, the range of LAN/PAN technologies (for example, Wi-Fi, Bluetooth) is quite enough.
- Scalable Coverage: Mesh networks are helpful in increasing coverage in large structures or industrial facilities since they expand with new devices.
IoT Network: Is It Worth or A Trouble?
The IoT networks are very advantageous, but they also present specific difficulties. On the one hand, IoT networks are helpful in automation, enhancing productivity, and providing information on analyzing the gathered data. They can change industries, improve product portfolios, and spur growth. However, using IoT networks is not always easy and inexpensive, and it is necessary to consider it in detail. Another challenge is security and privacy since IoT devices are prone to hacking if not well protected.
By 2024, it is not a question of whether IoT networks are worth it or not but how to implement them in the best way possible and, at the same time, how to mitigate the risks associated with the implementation of IoT networks.
Takeaways
On our journey towards 2024, IoT networks remain the fundamental structure of contemporary technology, linking numerous devices, sensors, and systems that enable optimization and development in numerous sectors. IoT networks are useful in several sectors, such as healthcare, agriculture, manufacturing, smart cities, etc. Choosing the right IoT network is an important decision that is key to the success of any deployment. The Cellular Networks (4G/5G) provide high bandwidth with low latency while LPWAN is characterized by wide coverage and low power consumption of devices; LAN/PAN technologies such as Wi-Fi and Bluetooth are efficient for localized coverage and Mesh Networks can be scaled up as per the requirement.
The selection of the proper IoT network depends on the following factors: cost of the network, bandwidth usage, energy consumption, and the coverage area. These are critical in making sure that the network is well prepared for the current operations as well as future growth and evolution of the network. These are some factors that should be considered to get a good fit so that the IoT infrastructure will be ready to support the organization’s growth and its dynamic needs, which makes this decision strategic.
However, the deployment of IoT networks has its difficulties, especially in security, privacy, and deployment. Since IoT devices and networks are usually under threat from cyber criminals, security should be well implemented. Also, the implementation of various devices and systems in a single network may be a challenging and time-consuming task that needs precise preparation and control. But, if the IoT networks are planned, decided, and risk managed effectively, then the IoT networks can be taken to the optimum level to bring in automation, productivity, and innovation and to open up new frontiers of technological development in industries and in society beyond 2024.
