What is the IoT?
The Internet of Things, or IoT for short, is the concept of connecting physical objects to the Internet so that they can be either controlled or monitored remotely, with the goal of gaining insights that help improve personal or business outcomes. Physical objects can either be connected directly, or via sensors that are attached to the object. Objects can be anything from everyday personal things such as doorbells, thermostats, lights, or watches, to industrial or commercial devices such as solar panels, medical equipment, point-of-sale terminals, factory robots, parking meters, vehicles, all the way to the environment itself: rivers, forests, public spaces, etc.
There is a wide variety of examples for how IoT can add value to businesses and the world. The following paragraphs provide a mostly comprehensive overview of IoT use cases, with short descriptions and value propositions for each.
IoT use cases in healthcare …
An IoT SIM card, also known as M2M SIM Card (machine-to-machine), is a Subscriber Identity Module that is used in IoT (Internet of Things) devices to identify them as they try to connect to a 2G, 3G, 4G-LTE, Cat-M, NB-IoT, or 5G wireless cellular network. IoT SIM cards are typically billed monthly through IoT Data Plans.
M2M SIM cards, also called Universal Integrated Circuit Cards or UICC, store the credentials and security keys that uniquely identify a cellular subscription. The SIM uses a so-called IMSI number, or International Mobile Subscriber Identity, which is unique for every connected device on or off the network, anywhere in the world. SIMs also run an application that passes that identity information to an onboard cellular modem. The modem in turn, also known as "radio" or "radio module", conducts the actual attachment operation to the network. The application that the SIM card runs, by …
Whether you’re a new IoT device builder or have years of experience under your belt, you may not be aware of all the innovation happening around cellular connectivity in particular. For example, did you know that there is a solution that’s overcoming the challenges of legacy carrier or reseller approaches to IoT SIM cards?
Meet Twilio Super SIM. We recently went GA (Generally available) with Super SIM and marked the occasion with a webinar where we summarized what it is and how it solves the challenges of cellular IoT connectivity. Besides the positive feedback, the number of questions from our audience was overwhelming.
We’re addressing your most pressing questions in this blog.
Let’s get started.
Where do you provide coverage maps showing total coverage of Super SIM?
Super SIM offers access to almost hundreds of networks in over 170 countries across various radio access types, including 2G, 3G, 4G-LTE and …
What is IoT connectivity?
The Internet of Things (IoT) refers to the billions of everyday objects that are now connected to the internet. And the world of IoT is expanding dramatically. IoT technology is being leveraged globally to drive innovation in industries such as healthcare, agriculture, transportation, including connected vehicles, and security. The International Data Corporation (IDC) projected global IoT spending to reach $742 billion in 2020 and predicts the figure will grow 11.3% per year through 2024. Every day, industry leaders are choosing to invest in IoT.
This is a big deal. This behemoth of technology space is changing the world as we know it, shaping how we live, work, and engage with each other and with the physical world. Statista predicts the number of connected IoT devices will triple from 8.74 billion in 2020 to more than 25.4 billion in 2030.
Why does IoT connectivity matter?
While use cases for IoT abound and deployments are growing rapidly, the technology landscape can still be overwhelming to newcomers. This article gives an overview of wireless connectivity protocols and their respective strengths, weaknesses, and recommended fields of application.
The ever-expanding IoT
Enterprises and government agencies are leveraging Internet of Things (IoT) technology to maximize efficiency and reduce operating expenses while improving service delivery to their constituents. By implementing connected solutions, IoT is driving advancements across a wide variety of vertical industries, including utilities, connected vehicles, agriculture, healthcare, transportation, and security for businesses and homes. IoT is also driving new opportunities for innovation – solving problems while delivering global economic and environmental change.
The growth in IoT over the past few years and its future market potential are both impressive. The market intelligence firm International Data Corporation (IDC) estimates IoT spending was approximately $742 billion in 2020. Looking forward, …
There is a new kid on the SIM block: the eSIM. But don’t confuse this with embedded SIMs! Oh and there’s eUICC, and 1FF, 2FF, and 3FF, too. And what is an MFF2? This post will help. Let’s dive right in!
A SIM (Subscriber Identity Module), also called a Universal Integrated Circuit Card or UICC, stores information that uniquely identifies a cellular subscription. For about three decades now, the SIM has been what lets us connect (“attach” in tech speak) our devices to the cellular networks of the world. It holds the credentials and security keys necessary to identify a subscriber. That identity comes in the form of a so-called IMSI number, or International Mobile Subscriber Identity, which is unique for every user or device on or off the network. SIMs also run an application that …
So – you have an idea for building a connected device, which would let you tap into the promises of the Internet of Things. Maybe you’ve worked out a business case, showing how the investment of building the required infrastructure to maintain your device will be counteracted by the benefits expected from being able to collect usage data and control the physical asset. Whatever the case, chances are you’ve underestimated what it takes to build and maintain IoT devices and make everything reliable enough to serve your business properly.
Twilio’s decades of collective experience helping companies bring IoT products to market unfortunately show us that too many businesses simply fail their business case: it takes them years – not months – to establish reliable connectivity, and many give up before reaching a return on investment or even a functioning deployment.
In this post, I’ll explain the challenges of IoT, …
