What is the Internet of Things? The Internet of Things provides a layer of digital intelligence that will improve the "smartness" of the device. When a device possesses the capabilities of internet connectivity, then it starts bearing every attribute of being "smart," as is the case with a smartwatch, smartphone, or smart refrigerator.Lisa Taylor, the head of IoT marketing at Ericsson, provides a vivid explanation of the internet of things. According to her, the internet of things is basically a network of devices with the ability to use software and an internet connection to connect to each other and exchange data.IoT is used in my devices, including smart thermostats capable of figuring out the temperature you prefer to keep in the house, an intelligent lock that can respond to the command received from a smartphone app; a smart toy that could help put the child to sleep.Larger equipment is not left out in the application of IoT, as there are driverless cars, jet engines, and machine sensors in factories that apply the machine-to-machine principle (M2M). These applications are related to the Industrial Internet of Things or, better still, IoT.In the past, IoT devices were not usually capable of internet connectivity. For example, there are innovative technologies developed at CES with the concept of the Internet of Things that is comical and amazing simultaneously, like connected diapers that alert you on occasion when it needs to change and pillows that prevent your partners from snoring. However, the functions performed by IoT are not the only merits.Many predictions and insights can be derived from the data, allowing the necessary actions to be taken. IoT and Big Data Big data is a large amount of data gathered by smart devices connected to the internet. Predictive analysis helps to evaluate the best means by which a product can be marketed using the collected data.For years, many firms have been gathering data and have no idea how to apply it. The high value placed on data makes data science a lucrative job within the tech industry.The estimations made by Cisco indicate that M2M connections will constitute about 50% of the total 27 billion devices and connections, and 5% of the global IP traffic will emanate from these devices. Internet of Things and the Cloud Internet of Things devices are capable of exchanging a large amount of data. That is useful for companies where the cloud is applied for data processing purposes.Cloud computing giants like Google Cloud, Amazon Web Services, and Microsoft provide these IoT services. The genesis of the Internet of Things revolution? The inclusion of sensors and intelligence within devices used in everyday life became a topic of discussion in the late 80s and 90s when bad fashion and good music were in vogue. The technology to lead the Internet of Things revolution was unavailable at this time. Hence, there was little progress made.ZDNet's Steve Ranger is quoted as saying that the introduction of RFID tags (low-power chips capable of wireless communication), accessibility to broadband internet, and wireless connection help in pushing the concept of IoT forward. The adoption of IPv6 has also played a significant role in improving IoT technology.The phrase "Internet of Things" was coined by a British innovator in the technology field, Kevin Ashton, in 1999. However, it didn't live up to its vision until a decade passed.Initially, the use of the Internet of Things was only restricted to manufacturing plants and factories. These days, IoT has diversified such that there are now smart homes equipped with smart security systems, AI-powered speakers, and IoT-enabled thermostats. How can businesses benefit from IoT? The applications of the Internet of Things in business include the identification and analysis of issues on a remote basis, providing insight into when and where maintenance is required, and ensuring that there is no deficiency in the production line.Coincidentally, the company revenue is directly affected by these applications. Additionally, the Internet of Things is evolving at a fast rate, and businesses are incorporating the use of IoT into its operation. The reliance of an enterprise on IoT is referred to as digital transformation.According to the International Data Corp., it is projected that the utilities ($73 billion), transportation ($85 billion), and manufacturing ($189 billion) industries will take the bulk of IoT expenditure this year.In the same light, Taylor provides a brief overview of the potential of IoT; She believes that IoT can transform industries, and as part of the 4th industrial revolution, IoT is here to stay. She also mentions that IoT affects everything with an ability to connect to the internet, which makes IoT an ecosystem of ecosystems where competition plays a major role.Putting more perspective on IoT, she thinks that cooperation is highly needed when it comes to IoT, and the data collected by connected devices is of great value in the IoT sector. The advantages of IoT for individuals Let's assume you have a refrigerator with the Internet of Things capabilities. A mobile app on a smartphone can give you a visual perspective of the fridge's inside, even when you are at the grocery store.With IoT light bulbs at home, a simple voice command can switch on or off the lamp. IoT has limitless potential. Are there any security flaws in IoT? A major disadvantage of the Internet of Things is the possible information theft and other security issues. When a device is connected to the internet, there is an excellent chance of falling prey to hackers.As of late, consumers and businesses have been worried about the security risks and reduced privacy levels obtained from IoT applications. Almost everyone dislikes sharing personal information without permission; however, personal data is gathered and evaluated when a customer registers for an app or gives specific information to a smartwatch manufacturer.Personal details of the occupants living in an apartment can be obtained from sensors in various devices available within the home. For instance, manufacturers can detect even sexual intercourse if both partners are wearing a smartwatch that tracks heart activity through real-time data. According to a ZDNet article by Steve Ranger, IoT links the digital space to the physical world.That implies that hacking into IoT-enabled devices has dire consequences that affect the real world. For instance, deceiving employees in a power station into making a rash decision is often the case when the sensors regulating temperature are hacked. A similar calamitous situation may happen when a driverless car is hacked. How is IoT employed in certain smart cities and industries? IoT for manufacturing In M2M, otherwise referred to as Industry 4.0 and the Internet of Things, tracking the functionalities of manufacturing equipment is often done using sensors and advanced analytics. With predictive analytics and maintenance, there is less downtime, which often results in a loss of profit.Factories having IoT sensors incorporated into their equipment helps improve factory employees' productivity and efficiency, especially technicians.An innovative application of IoT is demonstrated with GE Aviation, which uses Upskill's Skylight industrial AR platform with Google Glass to increase efficiency and reduce maintenance errors.At Hershey, big data, machine learning, and cloud computing helped control manufacturing plants' production and prevent the loss of $500,000 in production for every 1% efficiency increase. IoT for smart cities Gartner reports that smart cities will have at least 2.3 billion connected items this year. A report by Navigant Research indicates that the global market for smart city solutions and services was worth $36.58 billion, and about $88.7 billion will be made by 2025. Many devices are IoT-enabled within smart cities, including sensors within parking lots to inform drivers about the availability of a free parking space when connected to a mobile app, video cameras installed within smart streetlights, gunshot detection devices, and weather sensors. Incorporating IoT solutions within smart cities lowers the cost of operations and increases energy efficiency. IoT for utilities Many companies require an effective means to meet the demand for water and energy. According to the International Energy Agency, it is projected that the global energy demand will rise by 28% in 2040.An Internet of Things solution in managing energy and water consumption is achieved with smart meters that connect to a smart energy grid to ensure that energy flow is regulated effectively.Smart water sensors are used to monitor water quality, temperature, pressure, and consumption. The data obtained via this means undergoes analysis in utility software and subsequently provides insight into water usage and how this is effectively managed.Furthermore, water leak detectors exist that identify leaks in pipes; consequently resulting in water wastage. IoT for transportation The installation of IoT in a vehicle provides remote monitoring and data analysis functions, which positively influence transportation and logistics. Businesses use the Internet of Things in terms of predictive analytics to solve problems before they arise in the case of a breakdown; information on better delivery routes is also provided, courtesy of IoT.On the other hand, individuals can link their IoT-enabled vehicles to their smartphones and homes for a seamless experience. IoT for retail Global Market Insights Inc., predicts that the retail market for IoT devices will exceed $30 billion by 2024. Information on the shopping experience of customers can be shared with retailers via video cameras, smart shelves, and beacons available within the retail store.Customers are also provided with shopping assistance from mobile apps and digital kiosks capable of delivering a personalized experience. Inventory tracking is better supplied with smart shelves.The data gathered by sensors brings into perspective consumer preferences and are subsequently used for decision-making as concerns marketing by the retailer. The data collected by IoT-enabled devices help retail businesses assign staff to areas in great need with a resulting optimization in operational efficiency. IoT for healthcare In a healthcare setting, the Internet of Things benefits medical care and management, the maintenance of medical equipment, and hospital operations.Many healthcare organizations have used IoT cloud platforms to monitor the purchase and use of medical supplies and pharmaceutics. Room temperature and the frequency of the patient's movement while on a bed can be assessed by IoT sensors.For patients not within the hospital environs, wearable sensors monitor the patient's vital signs and alert the doctor in case of an emergency. IoT for smart homes The number of IoT-enabled inventions for use in the smart home is growing daily. Almost every household item has become IoT-enabled, including smart refrigerators, smart thermostats, smart light bulbs, and smart speakers like the AI-enabled voice assistants from Google, Amazon, and Apple. A home security system in which a layer of IoT has been included can monitor visitors on a 24/7 basis. Additionally, the Internet of Things allows the possibility of locking the door remotely.A smart home is considered safer for the elderly than a conventionally furnished home, as teenagers can run to their aid when they get ill or injured.A CSG article titled The Future of the Digital Experience: IoT Edition report that 23% of consumers are users of smart home devices, and 36% of these users are only trying out IoT applications. What are the in-demand IoT jobs? Billions of IoT-enabled devices are available today, and greater accessibility to the Internet of Things in the coming years is no fool's tale.As the subject of IoT evolves, it becomes a profitable venture to involve in this field.

Security engineers, analysts, security specialists, architects, management specialists, and infrastructure engineers are jobs one could take under this category. The future of the Internet of Things? The evolution of the IoT field will continue, and affordability is assured as more IoT-enabled devices become available. The creator of the term "Internet of things" provides a vivid description of what IoT's future looks like.At LiveWorx, Ashton brings to light the current situation of the Internet of Things and its potential. He believes that the Internet of Things doesn't have the potential to progress linearly. Many IoT applications are introduced yearly, adding more value to IoT technology.He also mentions that IoT being present for 17 years doesn't necessarily mean a 17% completion level. His outlook on IoT applications shows that manufacturing processes, robotics, and transportation systems will see more IoT in the near future.Recently, a bulk of the attention has been drawn toward smart homes. However, Ashton insists that more focus should be placed on self-driving cars as they will radically change our lives.Taylor from the telecommunication giant, Ericsson, brings IoT's future into perspective when she says that connection to 5G is an expectation for the coming months. She mentions that interactions with their customers indicate that IoT and 5G cannot be discussed separately, which was the case a year ago.The emergence and growth of 5G technology will see the application of networks and distributed computing to solve complex issues. She believes that it is never too premature to begin by defining the use cases where IoT has a higher potential value.
