IoT sensors must have two radios for efficiency

Patrick nelson | November 20, 2019

For the Internet of Things to become ubiquitous, many believe that inefficiencies in the powering of sensors and radios has got to be eliminated. Battery chemistry just isn’t good enough, and it’s simply too expensive to continually perform truck-rolls, for example, whenever batteries need changing out. In many cases, solar battery-top-ups aren’t the solution because that, usually-fixed, technology isn’t particularly suited to mobile, or impromptu, ad hoc networks. Consequently, there’s a dash going on to try to find either better chemistries that allow longer battery life or more efficient chips and electronics that just sip electricity.

What Is CBRS and How Does It Help IoT?

Article | February 26, 2020

The Internet of Things continues to grow fueled by applications that solve problems for enterprise customers. One of the biggest barriers to IoT solutions in enterprise settings is reliable and low-cost wireless connectivity. Where Wi-Fi, Bluetooth, LoRa, Zigbee and others have tried to solve the problem before, CBRS (Citizens Broadband Radio Service) is posed to offer a viable alternative for enterprise IoT connectivity. Specific to the United States, Citizen’s Broadband Radio Service (CBRS) is a piece of the radio spectrum between 3550 – 3700 MHz. This is a valuable area of the spectrum because it allows good propagation (ability to penetrate walls and go medium distances) with the benefits of higher bandwidth services, such as LTE and 5G.

An Introduction to IoT Sensors

Article | March 5, 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.

5 Ways to Secure Your IoT Devices—Before They Get Hacked

Article | March 13, 2020

Internet of Things (IoT) devices make our lives more efficient and our day-to-day more convenient. They allow us to monitor our homes from afar, control our lights, thermostats, and locks and beef up the security of our homes—among a host of other things. But because smart devices have become so integrated into our lives, they leave us vulnerable to cybercrime too. In general, IoT devices have little to no built-in security, making them top targets for hackers. And since most IoT devices are interconnected, it puts your whole suite of devices at risk if even one gets hacked. Just as you lock your front door before you go to bed, you’ll want to make sure your IoT devices are secure before you start using them.

Frailties of LoRaWAN IoT Devices

Article | March 5, 2020

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.
