At Haystack, we are fans of Semtech’s LoRa LPWAN radio. Until recently, we considered the 915 MHz band as too noisy for low power IoT systems, but Semtech’s use of chirp spread spectrum combined with modern silicon capabilities gives them an edge in the growing LPWAN industry. We are particularly bullish on LoRa’s prospects for …
I saw this announcement and while I generally like and own multiple Samsung products, I felt the need to post something to commemorate the end of the LTE hype cycle for the mobile IoT. As in, nothing belies the hype of LTE-M as a low power WAN technology than seven day battery life on a mobile tracker. …
THE JOKE IS OVER. WE CAN STOP PRETENDING LTE-M IS A LPWAN Read More »
Sometimes making your wide area IoT device truly “wide area” isn’t as easy or as safe as it looks. One blind spot for many IoT technologies: roaming. Here’s a story about a non-profit group that tracks the migratory patterns of birds and found itself victim of a costly mobile IoT device theft: According to official broadcaster Radio …

We are doing exciting work at Haystack around low power IoT geolocation and more recently have begun work on a project to develop Proof of Location(PoL) using DASH7 running over LPWAN’s. One use case for PoL cuts to the heart of a weakness in many cryptocurrency architectures: concentration of mining power. (If you’re unfamiliar with what this means …

Note: this is the first in a series on implementing Proof of Location using DASH7 Recently our team began taking a look at how DASH7 will help blockchain applications with a hard-to-solve problem: authenticating the physical location of one or more parties in a smart contract. Smart contracts are computerized transaction protocols that execute the terms …

In a book I’ve read aloud at least 500 times called the Pig’s Picnic, a pig (Mr. Pig) wants to look his best when he asks Miss Pig to join him for a picnic. So after obsessing about which bow tie to wear, he takes advice from his friends Lion, Fox, and Zebra and borrows something …
ONE IOT TECHNOLOGY RESPONDS TO A GEOLOCATION DILEMMA Read More »
In a move that should shock no-one who follows movements in LPWAN technologies, Verizon announced they are deploying LoRa and apparently have no plan to deploy NB-IoT: Verizon Communications Inc. (NYSE: VZ), which launched the country’s first national LTE-M service in March, said it’s embracing LoRaWAN unlicensed technology for building overall solutions for some customers. That surprised attendees …
“All things excellent are as difficult as they are rare.” – Baruch Spinoza TL;DR: The mobile IoT needs GPS GPS is traditionally not low power Getting GPS right with low power requires a tricky confluence of technologies This month, I witnessed a “coming out” party of sorts for a new LTE NB-IoT product from Samsung. It’s …
There’s one LPWAN technology, LoRaWAN, that pretends to offer real-time geolocation when for all practical purposes it does not. Still, a few of its backers promote this capability — which is at best characterized as a hack — and hope customers don’t get wise until after the implementation. Other bloggers are catching on as well: But even worse is …
