Frailties of LoRaWAN IoT Devices

Low-power wide-area networks (LPWANs) are helping drive the Internet of things (IoT) explosion. They connect millions of low-power IoT and Industrial IoT (IIoT) devices into wireless networks over a range of distances, from short to really, really long, from indoor applications to those covering large fields or even cities. But device designers using the LoRaWAN standard may be lulled into thinking that just configuring its security keys is enough to prevent their devices from being hacked. A new report says it isn’t. Four protocols give enterprises a choice in LPWAN connectivity: cellular NB-IoT, LTE-M, and Sigfox, and the non-cellular LoRaWAN standard. Among these, the open LoRaWAN overwhelmingly dominates. Omdia (formerly IHS Markit – Technology) projects a “quite high forecast” for LoRa, said Lee Ratliff, senior principal analyst, connectivity and IoT.

Hitachi, Infineon promote IoT tech for viral detection

Article | February 18, 2020

Tech companies are stepping up Internet of Things technologies to protect against COVID-19 and future viruses by using LiDAR and infrared cameras to detect a person’s body temperature from a distance or even handwashing. Keeping the data secure in such detection is also going to be a challenge. One approach is to put a chip inside an IoT device when it is manufactured to enable strong authentication and secure communication, mainly to guard against device counterfeiting. Hitachi Vantara has touted forward looking infrared cameras (FLIR) cameras to detect the temperature of a person from a distance. That way a passenger on a train or a worker or a customer in a store can be non-intrusively screened, according to a blog from Mark Jules, global vice president of smart spaces and video intelligence.

IoT as a Service: Lowering the Cost Barrier of IoT for Small and Mid-Sized Businesses

Article | February 18, 2020

There are already 20 billion IoT-connected devices, and 8 billion of those are devices used by enterprises, according to a report by Gartner. The impact of the Internet of Things market is potentially $11 trillion by 2025. The investment in IoT has come primarily from large businesses, but the technology is increasingly available via ‘as-a-service’, making it possible for businesses of all sizes to benefit. The ‘as-a-service’ model reduces the cost of ownership and capital expenditures and makes it easy for small businesses to investigate IoT with smaller up-font investments and less risk. Frank Della Rosa, research director at IDC, said that “Software as a Service (SaaS) continues to be the most highly deployed cloud segment, representing a commanding 62.4% of the total cloud market revenues.”

An Introduction to IoT Sensors

Article | February 18, 2020

This post will cover various important sensors that are possibilities for an IoT deployment. Sensors are the backbone of any IoT deployment. They gather information and provide software with sensory information it needs to achieve its full potential. In addition, this post will go over considerations and decision-making for selecting sensors in an IoT deployment. Often times, a single sensor is not the best implementation, a suite of sensors can gather more data and even affect behavior for other sensors. In many cases, more than one sensor is necessary to perform the IoT deployment’s function. Sensors are just as critical to every IoT application as the internet. Imagine Alexa or Google Home without a microphone: it wouldn’t work. People wouldn’t be able to interact with the device, or it would need some other kind of sensor such as a keyboard to obtain input from a user.
