Personal navigation has never been easier. With numerous options from GPS and cellular to Wi-Fi and Bluetooth, it can be challenging to select the right one for your product be it micromobility scooter or a fleet of logging trucks. To understand which solution is right for you, it’s helpful to have a high-level perspective on the most popular and widespread geolocation technologies. Most geolocation solutions should start with GPS since it’s a system designed from the start to answer the question, where am I? With close to ~4-meter accuracy, it’s a no brainer to start any navigation solution here, unless of course, your use-case is underground. Unsurprisingly, no single navigation solution is right for every product use-case or fleet deployment. What works for a micromobility scooter a combination of GPS, cellular, and Bluetooth would be an over-engineered solution to keep track of your keys. For that, something like Bluetooth beacons are more appropriate.

IoT developers to focus more on smart healthcare post-COVID-19

Article | April 2, 2020

Healthcare technologies will be a greater priority among IoT service providers once the disruptions caused by the COVID-19 die down, according to Forrester Research. Based on its latest figures, only 7% of the work that major IoT service providers deliver in APAC is on Smart Healthcare. The crisis has triggered a lot of ideas and solutions, however there was simply no time to look at a more strategic approach for both the technologies and the processes. This will be the focus of governments, health care providers, and others, once the acute crisis is behind us,” said Achim Granzen, principal analyst at Forrester, told FutureIoT. He added: “I expect this number to increase past Covid-19, as governments, healthcare providers, and others will seek to harden many of the ad-hoc systems and measures they have put into place during the crisis.”

How to Effectively Monitor Utility Usage With IoT for Maximum ROI

Article | March 3, 2020

Operating a utility business can be particularly difficult, especially when you’re trying to maximize ROI. In the water utility space, per capita water usage has decreased while the water itself has become more expensive to collect. Across utilities sectors, aging infrastructure takes a large cost to maintain and eventually update. Consumer expectations and regulations also can cut into ROI. As they should, people expect clean and safe water and a continuous supply of electricity. The driving factor in the utilities space is efficiency. Enter the smart water meter. For our IoT water management solution, we used Google Cloud Platform (GCP). GCP has various benefits for water management through its wide array of products. We will go over two important features of a water management IoT solution.

Top ‘avenues’ for developers in smart cities

Article | April 1, 2020

Perhaps no more than a decade ago, the notion of ‘smart cities’ probably implied thoughts of which metropolitan areas could be said to have the greatest density of schools, colleges and universities. You want a smart city? Okay, how about Oxford, Cambridge, Massachusetts, Washington DC, Paris and so on. But that’s (obviously) not what we mean by smart cities today. In this post-millennial age, we define a smart city is a municipality that uses information and communication technologies (many of which will gravitate towards the Internet of Things (IoT) and the data backbones that serve it with application processing, data analytics and increasing amounts of AI) to increase operational efficiency, share information with the public and improve both the quality of government services and citizen welfare.

The Internet Of Things is all over HVACR. Is the value there yet?

Article | March 23, 2020

AHR Expo used to be mostly a “mechanical engineering” event, and even in 2017, when I first got there, there were just a few companies who mentioned IoT or connectivity at their stands. Only the most prominent players in the HVACR industry presented their IoT solutions. In my conversations with companies at that time, no one was taking IoT very seriously. And it’s understandable, there already were Modbus, BacNet – well-defined protocols to connect machines to a PC or PLCs to make them work in unison without any Clouds and external access.
