How Far Does Your Radio Shine? Detectability of Four Consumer Radio Sending Devices
Is a smartwatch with Bluetooth really a risk in the field? We calculate how far four everyday radios can be detected: a smartwatch, a smartphone, a LoRa mesh node and a handheld UHF radio. From 100 m inside a forest, the watch is detectable at about 80 m and the handheld radio at about 11 km.
sweTAK on the wrist: tactical awareness and soldier health, without the cloud
Nerio Defense is taking sweTAK from the phone to the wrist. A purpose-built sweTAK Watch application for Garmin puts heading, the unit’s alerts, one-button signals and soldier readiness on the soldier’s arm, with a direct link to the phone and no cloud, while Apple Health and Health Connect open the same picture to any wearable.
Measuring health state by light through skin
Your watch measures exactly one thing: how much light comes back out of your wrist. Everything else — heart rate, sleep, stress, recovery — is inference built on top. Drawing on 165 studies of soldier physiology, we look at what optical sensors genuinely reveal about stress and health, what they cannot, and why their errors all lean toward telling you that you are fine.
What soldiers told us: field-testing sweTAK alongside Signal and ATAK
This spring, Nerio Defense joined a field test comparing Signal, ATAK and sweTAK under realistic conditions. Here’s what 36 soldiers told us about each tool — why familiarity still wins, where sweTAK proved its purpose, what we need to fix, and the smartwatch ideas that emerged from the field.
The Importance of Long-Term Physiological Monitoring for Soldier Readiness and Resilience
Modern military operations demand continuous insight into a soldier’s physical and mental readiness. Nerio Defense — supported by Samsung through advanced biosensors like the Galaxy Ring and Galaxy Watch Ultra 8 — is developing tools that monitor vital parameters such as HRV, blood oxygen saturation, blood pressure indicators, energy and stress levels. Long-term tracking reveals early signs of fatigue, reduced recovery or elevated stress that traditional checks miss. With intelligent analytics, commanders gain a clearer, proactive understanding of readiness, improving safety, resilience and mission performance.
Why the Soldier Needs Automation – Thoughts on Innovation from FMV’s “Omvärld”
The modern soldier is expected to operate in increasingly complex environments – yet most lack even the most basic digital tools. In FMV’s publication Omvärld, Nerio Defense highlights a critical need. At Nerio, we believe automation and intuitive communication tools must become standard for every soldier.
