  • R

    RF-powered computing

    RF-powered computing is the use of radio frequency (RF) signals to enable the operation and communication of low-power devices, typically for machine-to-machine (M2M) networking.

  • RFID (radio frequency identification)

    RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.

  • RFID skimming

    RFID skimming is the wireless interception of information from RFID chip-based debit, credit and ID cards and other documents, such as passports. The purpose of RFID skimming may be simple theft or more complex identity theft. Most typically, thieves use an NFC-enabled device that records unencrypted data from the card's RFID chip, which is broadcast into the air.

  • RFID tagging

    RFID tagging uses small radio frequency identification devices to track and identify objects.

  • RFID virus

    An RFID (radio-frequency identification) virus is malicious code inserted into an RFID tag to alter or corrupt data in an RFID system.

  • RIOT operating system

    RIOT operating system is an open source operating system specialized for IoT (internet of things) devices.

  • robotic process automation (RPA)

    Robotic process automation (RPA) is the use of software with artificial intelligence (AI) and machine learning capabilities to handle high-volume, repeatable tasks that previously required humans to perform.

  • S

    sensor analytics

    Sensor analytics is the statistical analysis of data that’s created by wired or wireless sensors.

  • sensor data

    Sensor data is the output of a device that detects and responds to some type of input from the physical environment. The output may be used to provide information or input to another system or to guide a process.

  • sensor hub

    A sensor hub is a connection point for multiple sensors that uses a multipoint control unit (MCU), coprocessor or digital signal processor (DSP) to compile and process data gathered from those sensors.

  • smart bulb (smart light bulb)

    A smart bulb is a networked LED light bulb that has additional features to enable automation, presence-sensing capabilities and customization.

  • smart city

    A smart city is a municipality that uses information and communication technologies (ICT) to increase operational efficiency, share information with the public and improve both the quality of government services and citizen welfare.

  • smart farming

    Smart farming is a management concept focused on providing the agricultural industry with the infrastructure to leverage advanced technology – including big data, the cloud and the internet of things (IoT) – for tracking, monitoring, automating and analyzing operations.

  • smart grid sensor

    A smart grid sensor is a small, lightweight node that serves as a detection station in a sensor network.

  • smart home app (home automation app)

    A smart home app, sometimes referred to as a home automation app or a smart home automation app, is an application used to remotely control and manage connected non-computing devices in the home, typically from a smartphone or tablet.
