IoT makes it possible for devices to be smart and connected, producing data that generates knowledge and makes our daily lives more efficient and our economy more heated. The future of the internet of things has the great potential of software and the internet to the physical world, revolutionizing our way of life through sensors, information, encryption, and clouds. Several revolutionary technological tools are converging to multiply the opportunities generated by connecting devices that are part of our daily lives. We are on the right path for the connected device revolution to improve our quality of life and transform how we work and be gas in our economy, creating jobs, industries, and opportunities for a more prosperous future.
Ever Wondered how smart devices discover one another, query for services, and exchange information? Yes, it’s cool and just as helpful that your fitness tracker can share information about how you successfully ran in the morning with your smartphone. So, we ask, what is the underlying technology that makes any of this possible? Bluetooth Low Energy takes the spot. What is Bluetooth Low Energy? BLE (aka Bluetooth Smart) is a wireless means of data transfer specially designed for low cost, low bandwidth, and low power applications/devices. The keyword is low. It is a variant of the Bluetooth communication protocol introduced in June 2010 in the Bluetooth 4.0 Core Specification by the Bluetooth SIG (Special Interest Group). This standard is optimized to provide the lowest power consumption compared to other wireless communication technologies. Thus, it has opened many doorways of opportunity for product designers on a low-cost budget and a tight energy budget where battery life is a higher priority than high data transfer speeds.
We live in an exciting era. Although we might not notice it at first, every day, better, faster, and more intelligent technology is made. Whether is the advancement of our smartphones, TVs, or home appliance or it is an advancement in another field, we are surrounded by constant and fast development. Around 14 years ago, Apple released its first iPhone. Since then, every smartphone has become better and smarter and, more importantly, easier to use. From improved batteries to enhanced cameras and memory chips, smartphones have come a long way. It is incredible how much in the last 15 years has been done. The advancement of the components is mind-blowing. This is, of course, due to the high demand for this technology, which motivates engineers to continue seeking a better solution.
There are many topographies of how a sound IoT system should look. They all share the same idea – it all starts with the device or thing which generates and provides the data. Data from one or multiple devices are gathered, aggregated and sent to storage or cloud service. Probably one of the most critical elements of IoT is Analytics. Analytics tools incorporate all possible ways, including statistics, machine learning, big data technologies to make data understandable and useable. This data can then be accessed through the user interface. User should have the ability not only to see the information but also alter it and even control the devices and actuators if needed. Depending on IoT specifics, there can be less or more components. Anyway, this doesn’t change the logic of data and control flow. Probably the critical factor of sound IoT system is that each element is independent of each other and can be used as a distinct building block. Such an approach makes IoT solution management and maintenance more comfortable as each component can be used in any configuration. Let’s go through all parts to see what are the key features
We hear about the Internet of Things (IoT) for quite some time. I think it is safe to say that IoT started with the first internet message sent on 29 October 1969 over ARPANET. It appears that Kevin Ashton first pronounced the term of Internet of Things in 1999. I could be wrong, but I’m fairly sure the phrase “Internet of Things” started life as the title of a presentation I made at Procter & Gamble (P&G) in 1999. Linking the new idea of RFID in P&G’s supply chain to the then-red-hot topic of the Internet was more than just a good way to get executive attention. It summed up a valuable insight, which is still often misunderstood. Kevin Ashton
