2G/3G Sunset

Our friends at Multitech remind us about impending 2G/3G sunset with the US carriers.

Replacing the cellular-based sensor infrastructure takes time and good planning. Don’t be caught off-guard.

LoRa is a proven, low-cost alternative to LTE, especially for Smart Ag applications. Zenseio has had LoRa sensor solutions deployed on fields for the last year, and customers are happy to dramatically reduce their recurring connectivity costs.

IoT Hacking for a Greater Good and Profit

What will happen when you lock a bunch of hackers, entrepreneurs, and mentors into a room for two full weekends, give them powerful tools, dangle a valuable prize, and ask them to come up with an idea for an industrial IoT product? This was an experiment masterminded by my dear friend from college days, Tahir Hussain, who heads a tech accelerator – Collide Village in the Dallas metroplex. And, it was executed just recently.

On a fall afternoon last year, Tahir told me about his hackathon idea and asked me to provide mentorship as well as to sponsor Zenseio IoT hardware for the event. He was lining up the leading IoT companies as partners and successful local businessmen/entrepreneurs as mentors. It sounded like an interesting idea, so I jumped on it without hesitation. More info

IoT Security and 100 Million of Volkswagens

Researchers just published a startling discovery we’d never want to read about. It turns out that 100 Million Volkswagen vehicles sold since 1995 can be relatively easily hacked to open doors wirelessly without having the key.

It turns out 100 million vehicles used only a handful of private shared keys. Once a single private key is breached, millions of vehicles are compromised. The way cryptography based on Pre-Shared Key (PSK) works is that two devices (a vehicle and a key fob, in this case) share a secure private key that was programmed at a factory or at a dealership. This private cryptographic key, along with a rolling code are used for encrypted wireless transmission of authenticated commands to open/close doors.

IoT Epoch Time Disaster? Only Time Will Tell

Ever heard of the “epoch time”? I’m not talking here about  history periods or geology. Epoch time is simply a standardized time and date reference used in UNIX and many other computers. It defines time, measured in seconds, starting from January 1, 1970 epoch. This is based on an arbitrary, somewhat historical epoch, but, what matters is that it is a commonly followed standard.

What is the anatomy of IoT sensor devices?

Executive Summary:

  • IoT Sensors include three fundamental functions: sensing, communication, and power supply, as well as additional functions: processing/system management and user interface
  • IoT application is determined by the types of sensors, cloud connectivity, power sources, and (optionally) user interface used in an IoT sensor device
  • It is possible to realize a variety of IoT applications with a single IoT sensor hardware platform by employing appropriate functional modularity and interface abstractions
  • An application processor and well defined interfaces help abstract functions for versatility and ease of use

Key considerations for IoT sensor devices: 4 – Security

Executive Summary:

  • Security is critical for IoT
  • End application defines security policy requirements
  • Security is weak if device crypto key are not well protected in IoT devices
  • Best-in-class security policies for IoT sensors are achieved with tamper-proof hardware crypto key management

Key considerations for IoT sensor devices: 1-Versatility


With my two decades of experience designing complex electronic systems as well as recent two years focused on building IoT systems and solving System Integrators’ pain points, several key characteristics became evident to me that define the best-in-class industrial IoT sensor devices:

  1. Versatility
  2. Power consumption efficiency
  3. Ease of use
  4. Security
  5. Industrial deployment readiness
  6. Cost effectiveness

Now, I will cover each consideration in more detail. More info


What are IoT sensor devices?

The previous article – “What Are IoT Sensors?” – gave a high level overview of IoT system, now let’s drill down to what are IoT sensor devices.

Executive Summary:

  • IoT sensors are necessary components of any IoT application
  • Consist of sensors combined with communication capabilities
  • Many different types of sensors exist
  • Wireless communication is key to new applications
  • Multiple wireless standards exist since no one size fits all
  • Need a way to abstract application from sensing and communication methods

What are IoT Sensors?

Internet of Things (IoT) is such an overloaded term that it can mean many things to many people or nothing at all.  The purpose of this series of articles is to explain what some of these popular terms mean in the context of the latest technologies. Then, I will segue into something much more valuable to learn about – the anatomy of (IoT) “things”, how they fit into the larger Industrial IoT landscape, and what are the key considerations for connected sensors (“things”), especially as they relate to industrial applications.
