channelsounding Trilogi 1 i Metirionic GmbH 's Bluetooth SIG Channel Sounding-serie er nu færdig og let tilgængelig. I løbet af de sidste seks uger har vi fulgt, hvordan Bluetooth udviklede sig fra en simpel kabeludskiftningsradio til en sensorteknologi, der kan give reel rumlig bevidsthed. Hver episode bygger op mod dette skift, fra historie, til signalbehandling, til antenner, og i dag afslutter vi den første bue. https://www.linkedin.com/posts/jsnellis_bluetooth-bluetoothle-channelsounding-share-7473475769575419904-FUaH/

Når alle ting snakker sammen Imagine never needing a key because every device that can ID an aspect of us from the way we walk to our ear print, finger print, body temperature, heart rate, etc. authenticates us to our car and lets it turn on or opens our doors and offices, etc. All of these seemingly disparate pieces of information measured by many quasi-conscious devices can together form a complete picture of us that is unique to us and can authenticate us without any extra effort from us. https://www.linkedin.com/pulse/musings-internet-things-pickles-rey-tamayo/

Whofi Som ringe i vandet Because your body speaks in distortions. No chases. No explosions. Just static in the air. But something’s watching. Not with eyes. Not with cameras. With Wi-Fi. A shift in the signal. A ghost in the channel. Someone moved—and the network knew. That’s the new frontier. And its name… is WhoFi. https://www.linkedin.com/pulse/signal-never-lies-tech-thriller-were-already-living-nilanjan-roy-w2nqc/ ISAC To ensure common language “Integrated Sensing and Communications” (ISAC) is the term commonly used for standardizing “radar-like” functionality within 6G. This is the idea of re-using the radio broadcast to identify and track objects by wave reflection (like radar does). The technique proposed is not unique to the mobile industry at all, and the broader and more appropriate term used is “Wireless Sensing”. Wireless sensing is not restricted to mobile or 6G: IEEE 802.11bf for Wi-Fi which is commercially available. UWB (Ultra Wideband) Radar is already available in new cars and smartphones. Bluetooth 6.0 (2024) introduced Phase-Based Ranging (PBR). Passive radar (using a passive receiver to notice “wave shadows” and object position. These are like-for-like technology alternatives, most are short distance, except for the niche passive radar solution that tends to be more for military and similar application. https://www.linkedin.com/pulse/isac-what-good-geoff-hollingworth-vu6qc/
