Industrial IoT
Machines, computers and people enabling intelligent industrial operations
using advanced data analytics for transformation business outcomes
Internet of Bodies (IoB)
Connected devices that monitor the human body, collect physiological, biometric,
or behavioral data and exchange information of a wireless or hybrid network.
Can be
implanted, swallowed or worn.
Wireless Personal Area Network (WPAN)
Short-distance network that allows multiple devices within a small area to
connect to each other.
Examples of a WPAN are Bluetooth and Zigbee.
,Sensors
Devices that respond to inputs from the physical environment and use those
inputs for decision-making by displaying the inputs, transmitting them for
additional processing, or using them in conjunction with artificial intelligence
Sensor data
Measurements of some physical property. Data has values, a time and location.
There are fixed and mobile sensors.
Actuator
Device that converts an electrical signal into a corresponding physical quantity
such as movement, force, or sound
IoT devices
Simple networked devices such as sensors and actuators that are installed close
to the data source or control interfaces. Usually connected via 3G, 4G, 5G, Wi-Fi,
PCIe, USB or Ethernet within an edge computing application scenario.
Edge processing
A process of data aggregation, manipulation, bandwidth reduction, and other
logic directly on an IoT sensor or device
Access network
Part of a network which is concerned with moving data to and from a sensor or
edge device to a backhaul network
,Gateway
Building block used to move collected data (from sensors) to the central IoT
platform.
LPWAN (Low Power Wireless Area Network )
Lower than 1 GHz, 868 MHz in EU called ISM (Industrial, Scientific, and Medicine)
band, USA 915 MHz
Several techs that use this band are Sigfox, LoRaWAN, and Weightless
LPWANs have lower data rates compared to normal cellular ones
WLAN (Wireless Local Area Network)
Group of collocated computers or other devices that form a network based on
radio transmissions rather than wired connections
What are the 4 things to consider when choosing IoT connectivity?
Data rate, power availability, range, cost
Customer Edge Device
Devices that receive data from and send commands to IoT devices.
Mobile Edge Computing (MEC)
Computer node that focuses on data aggregation, compression and
transformation. The
___ server may suffer from resource limitation.
, Centralized IoT platform
Powerful central storage and processing capability for IoT use cases
such as data interoperability and uniform data access. Handles
management of IoT devices for remote management.
UNB (Ultra-Narrow Band)
Systems transmit the signal in a small amount of spectrum, usually less than 1
kHz, and are particularly suitable for small amounts of data
Spread spectrum
Technique in which the signal is transmitted on a bandwidth that is much bigger
than the original frequency to decrease interference and increase security
LoRaWAN
based on LoRa protocol from Semtech.
is asynchronous and uses Spread spectrum.
Suitable for dense deployments such as buildings or cities.
Zigbee
Short-ranged network with meshing
SigFox
Named for company that owns it.
Used in Narrowband (200 kHz)
Suitable for dense deployments such as buildings or cities.
