The internet of things, defined
As 4G technologies mature and 5G deployments accelerate, mobile network operators are becoming less reliant on 2G and 3G technologies — both for data and, more recently, for voice. This change provides an opportunity to re-allocate radio spectrum from 2/3G to 4/5G.
The phasing out of these legacy (2/3G) technologies is commonly referred to as their sunset.Learn more

An APN allows a connection to the internet through a cellular network. It can also help separate traffic from other networks and defines the set of connectivity rules a device has as well as certain security measures. All cellular connected devices use either a public or private APN of some kind.Learn more
Bandwidth is defined as the maximum amount of data that can be transmitted over an internet connection in a specific range of time. In IoT bandwidth needs vary by use case.Learn more
Cat-M1 is a radio access technology that was designed specifically for IoT projects to transfer low to medium amounts of data across a wide geographic range. It is also known as LTE-M.Learn more
IoT data plans provide access to cellular data for devices. Unlike consumer cellular plans, they’re uniquely structured for use case and business needs. Good data plans take into account the number of devices, whether or not data usage will fluctuate, fleet location, and any additional tools or features provided.Learn more
An IoT data pool allows businesses to buy a set amount of data for a group of devices, rather than paying per device. This is often used when some devices use a lot of data, while others use little.
IoT device certification ensures that all devices on a cellular network meet security and interoperability requirements. Different kinds of certifications are required depending on where devices will be deployed and what carriers will be accessed.Learn more
An edge router is a device that connects an internal network to the internet. They’re used at the edge of your network, where your private network ends and the public network begins.Learn more
Embedded SIM (eSIM)
The eSIM is a SIM card that is soldered directly to a board inside a device. The eSIM is the hardware component that allows for cellular connectivity, whereas eUICC is the software component or operating system that allows for over the air updates.Learn more
Embedded Universal Integrated Circuit Card (eUICC)
eUICC is the software component that provides the ability to issue over-the-air (OTA) updates to SIM cards. eUICC-enabled global IoT SIM cards allow teams to build with one type of SIM card and deploy to different locations around the world. They come in multiple form factors.Learn more
Integrated Circuit Card ID (ICCID)
The ICCID is a globally unique serial number consisting of 19 or 20 digits that identifies a SIM card.Learn more
International Mobile Equipment Identity (IMEI)
An IMEI is a 14-digit number that serves as a distinct identifier for cellular devices.Learn more
International Mobile Subscriber Identity (IMSI)
An IMSI is a 15 digit number that determines a subscriber’s country of origin, mobile service network, and specific device identity.Learn more
Internet Security Protocol (IPSec)
IPSec is a set of protocols between two points on the IP network that provide data authentication, integrity, encryption, decryption, and confidentiality.Learn more
IoT cloud platforms are end-to-end services that provide the infrastructure for transmitting, computing, and storing data from IoT devices.Learn more
IoT connectivity links all of the elements of an IoT ecosystem and allows devices to send and transmit data. Common IoT connectivity types include cellular, Wi-Fi, ethernet, Bluetooth, RFID, and more.Learn more
An IoT platform is a software as a service (SaaS) product that can oversee a fleet of connected devices. Its features vary from product to product, but may include insight into device connectivity and location as well as the ability to manage devices and view connectivity billing information.Learn more
Latency measures how long it takes for data to travel from one point to another. Low latency means data is transferred quickly between device, network, and the intended outcome.Learn more
Low-Power Wide Area Network (LPWAN)
LPWANs are network technologies designed for minimal power consumption and the ability to achieve long-range communications. This includes NB-IoT and Cat-M1 among others.Learn more
Machine-to-Machine (M2M SIMs)
M2M SIM cards — also known as IoT SIM cards — are pieces of hardware embedded or inserted into devices that enable connectivity and allow devices to send and receive data across cellular networks.Learn more
Message Queuing Telemetry Transport (MQTT)
MQTT is a lightweight messaging protocol designed for IoT. It works well for sending messages to control outputs or read sensor data.
Multi-Access Edge Computing (MEC)
MEC is a kind of computing that processes data closer to where it is gathered, rather than in a central data center.Learn more
Multi-IMSI technology allows several IMSIs, or International Mobile Subscriber Identities, to be loaded on a single SIM. SIMs cycle through profiles until an available network is identified.Learn more
Mobile Virtual Network Operator (MVNO)
An MVNO is a connectivity provider who has negotiated agreements with several mobile network operators (MNOs) to gain access to multiple networks.
A native connection allows devices to access cellular data directly from the MNO that owns the infrastructure, rather than via a roaming connection. Native connections typically provide greater performance at a lower price than roaming profiles.
NB-IoT is a low-power, wide area network (LPWAN) technology that operates on the licensed spectrum and wass designed for IoT devices with low-bandwidth needs.Learn more
Network redundancy is an overlap of cellular coverage in case an IoT device travels outside of the original coverage area or the primary network experiences a disruption.Learn more
PTCRB is a standardized framework for device certification. The program verifies compliance with 3GPP network standards.Learn more
Point of Presence (PoP)
A PoP is a place where two or more networks or devices share one connection. PoPs are established local access points that allow for online communications and form the foundation of how we connect to the internet.Learn more
Radio Access Network (RAN)
The RAN is responsible for the connection between devices and the core network and implements a RAT. For example, UTRAN radio access networks implement UMTS and E-UTRAN radio access networks implement LTE.
Radio Access Technology (RAT)
A RAT is the physical layer of a radio (cellular) connection, such as UMTS (3G) or LTE. A single device may support multiple access technologies. A RAN implements a RAT.
Remote SIM Provisioning (RSP)
RSP ensures the SIM is accounted for in the databases that will determine whether or not it has the permissions to attach to a particular network or to a particular carrier. Beyond the initial SIM registration, provisioning can also include enabling the correct profile on a multi-profile SIM, or activating profiles on the SIM so they are ready to connect to the cellular network.Learn more
IoT roaming agreements allow devices to use multiple networks to access cellular data, rather than using a singular network. Roaming connections can often provide greater coverage and redundancy than native connections.
