    From Closed to Open Source: Revolutionizing the Satellite Industry with Ian Itz, Director of IoT at Iridium

    Ian Itz, Director of IoT at Iridium, explains the company's strategic pivot from a proprietary, closed-ecosystem satellite model to an open-source, standards-based approach leveraging Arduino and NB-IoT. He details how Iridium's legacy 66-satellite constellation supports global IoT data, noting that their previous 'Swiss army knife' modules were over-engineered for developers, prompting a shift to simpler, open-standard hardware. Itz also discusses the high capital barriers of satellite infrastructure, contrasting Iridium's narrowband focus with Starlink's broadband model, and highlights partners like Geoforce who build robust, long-life asset tracking devices for the oil and gas industry.

    Satellite Connectivity in IoT Solutions | Iridium's Ian Itz | Internet of Things Podcast

    Ian Itz, Director of Iridium’s IoT Line of Business, explains how Iridium’s Low Earth Orbit (LEO) constellation provides global, low-power connectivity for IoT devices in remote areas where terrestrial networks fail. He discusses the differentiation between satellite providers based on constellation architecture, highlighting Iridium’s 66-satellite network’s reliability for safety-of-life applications like Garmin inReach and GMDSS. Itz also outlines key growth sectors such as precision agriculture, mining, and environmental monitoring, while noting challenges like high costs and the industry’s shift toward standardized, multi-radio modules to drive mass adoption.

    Brandon Satrom Returns! Blues SVP talks Starnote, and cheap Satellite Communication!

    Ian Wiggins introduces Blues SVP Brandon Satrom to discuss the StarNote, a satellite communication accessory for Blues Wireless Note Cards that enables failover connectivity via JSON commands. Satrom explains how StarNote for Skylo lowers the barrier to entry for IoT satellite data by offering prepaid kilobyte-based plans instead of expensive monthly subscriptions, targeting use cases like asset tracking in remote areas. The episode also covers the winner of a Seeed Studio SenseCAP S2104 competition, Embedded World student initiatives, and a deep dive into Zigbee versus Thread protocols by YouTuber Great Scott.

    A Daring Space Rescue | PUF Protection | Reverse Costing

    George Leopold explains Northrup Grumman's successful docking of the MEV-1 satellite to an Intelsat satellite, marking the first in-orbit repair and extending the asset's life through refueling and repositioning. Maxim Integrated addresses IoT security vulnerabilities by integrating Physically Unclonable Function (PUF) technology, specifically Chip DNA, directly into microcontrollers to generate unique, non-stored cryptographic keys. Romain Fro, CEO of System Plus, describes their 'reverse costing' methodology, which goes beyond standard teardowns to estimate manufacturing costs by analyzing complex supply chains, yields, and indirect expenses for products like the iPhone 11 and Apple Watch 5.

    Combining Satellite and Cellular IoT | POND IoT's Alex Kotler | Internet of Things Podcast

    Alex Kotler, SVP of Sales and Partnerships at POND IoT, explains how combining satellite and cellular connectivity provides redundancy for IoT devices in remote or mobile environments like shipping and agriculture. He discusses the use of multi-IMSI SIM cards to manage global coverage and the strategic integration of Starlink with Peplink routers for high-bandwidth failover. Kotler highlights the industry challenge of educating customers who often choose cheaper, uncertified hardware, warning that 'cheap is very expensive' when reliability is required.
