Bluetooth, Wi-Fi, and Zigbee are all commonly used wireless technologies for IoT devices, each with its own advantages and applications.

A cellular modem's main purpose is to transmit data over cellular networks, allowing IoT devices to communicate with the internet and other devices.

LoRa (Long Range) is a low-power wide-area network (LPWAN) technology specifically designed for IoT applications, offering long-range connectivity with low power consumption.

Device onboarding refers to the process of connecting and configuring IoT devices to the internet and other networks, ensuring they can communicate and exchange data.

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol specifically designed for IoT applications, enabling efficient communication between devices and cloud platforms.

Gateways in IoT connectivity serve multiple purposes, including translating data formats, providing internet access, and aggregating data from multiple devices before forwarding it to the cloud.

Wi-Fi is known for its high bandwidth and low latency, making it suitable for IoT applications that require fast and reliable data transfer, such as video streaming and real-time control.

Multi-homing in IoT refers to the ability of devices to connect to multiple networks simultaneously or switch between networks based on availability and performance.

Bluetooth is a widely adopted short-range wireless technology used for communication between devices over short distances, such as connecting smartphones to wireless headsets or IoT devices to sensors.

A SIM card in IoT connectivity serves multiple purposes, including providing cellular connectivity, storing device information, and authenticating devices on a network.

Sigfox is a low-power wide-area network (LPWAN) technology designed for IoT applications that require long-range connectivity and the ability to penetrate dense objects, making it suitable for use in harsh environments.

Device management, network management, and connectivity management collectively refer to the processes of managing and monitoring IoT devices, their connectivity, and the overall network infrastructure.

NFC (Near Field Communication) is a short-range wireless technology that enables communication between devices when they are in close proximity, often used for contactless payments and data exchange.

Device-to-device communication, peer-to-peer communication, and ad hoc networking all refer to the ability of IoT devices to communicate directly with each other without the need for a central server.

Zigbee is a low-power wireless technology specifically designed for IoT applications, offering long battery life and low power consumption, making it suitable for devices with limited power resources.
