Does The Internet Of Things Really Need Dedicated Low-Power WANs?
Forbes – January 25, 2016 – The Internet of Things (IoT) is all about connectivity, so it’s not surprising that so many alternatives have arisen for getting data from “here to there”. For short range we have Wi-Fi, Bluetooth, ZigBee and Z-Wave, just to name a few. For longer range, we have had 2G / 3G and now 4G LTE, with the introduction of 5G still years from deployment. In addition, a new breed of low-power, long-range wireless networks (LPWANs) have arisen and are now being rolled out by companies such as Sigfox or Ingenu. Even some of the larger carriers have gotten into the game, such as Orange or SK Telecom, who have committed (or at least made some commitment) with a technology called LoRA. The question is, do we need these alternatives, or are they all just Band-Aids until we get to 5G? Read More>>
Why the Internet of Things Needs Another 10 years
ComputerWorld – January 22, 2016 – I first wrote about the hype surrounding the Internet of Things in 2004. Back then, industry analysts predicted that tens of billions of things would be connected to the Internet within five years. It didn’t happen. Read More>>
An IoT ROI Reality Check
Simple IoT ROI Reality Check
The IoT is projected to improve efficiencies in businesses and households around the world. For businesses and consumers to invest in the IoT, the money spent has to make sense. To help us ground our thinking, let’s check out a simple example calculating the ROI on a device investment. The numbers used in this example are completely hypothetical but represent the notional ideas common in the LPWA space. We’ll assume the investment can bring us a return (or savings through greater efficiency) of $5 a year after all costs are accounted for.
At first blush, this seems like a no-brainer investment. However, let’s take into account the longevity of the device’s technology which we will vary in this example from two to twenty years. Device life encompasses any change in condition that would require a truck roll. Truck rolls are expensive and often show up as hidden costs. Truck rolls would include replacing a battery or replacing the wireless module because the tech is sunsetting (as happens just about every decade with cellular technology). Expected years in service represents how long the device will be in service including any truck rolls needed to keep it working. Truck rolls will most likely be outsourced to a service provider. A truck roll is assumed to cost roughly $350 per device, which frankly, is conservative. A more realistic truck roll cost may be upwards of $500.
The second table shows the annual savings from owning a device with the given device and expected life cycles. The table shows that a device with truck rolls every 5 years to, say, replace a battery, and an expected service life of 15 years would have two truck rolls (one at 5 years and another at 10 years). The cells highlighted in black show the annual savings of $5 with no truck rolls. The cells in gray show the loss (negative savings) that results from needing truck rolls (because the device life cycle is shorter than the expected years in service).
What becomes clear is that truck rolls are an IoT investment killer.
In each case, the device life needs to be at least as long as the expected years in service in order to be profitable. As soon as a truck roll is required, the expected savings disappear. In order for an IoT investment to make sense it the savings have to increase 28-fold even to be considered. This result is logical, but the example helps really drive that home.
Here’s the beautiful flip side: with the longevity LPWA provides, it makes sense to invest in areas that require a much lower estimated savings per device. This is precisely how the IoT brings about the efficiencies it is proclaimed to bring.

Smart Cities, 10-Year Battery Life and LPWA to Spur IoT Momentum in 2016
The Fast Mode – January 2016 – To say 2015 was a stellar year for the Internet of Things (IoT) would be an understatement. The market leapt forward with great strides in all areas—number of devices connected, number of new applications, increased level of security, revenue generated…all in all, it was a great year for the IoT. As I look forward to 2016, here are some of the things I think will spur the continued growth of this dynamic market. Read More>>
