Interview about AURACAST™ : “The revolution in Bluetooth® technology is imminent”
In this interview, Thomas Rupp explains how new standards such as Bluetooth 5.2, LE Audio, and Auracast are fundamentally changing wireless audio communication. Arendi develops energy-efficient embedded wireless solutions and integrates modern broadcast audio technologies for accessible, scalable applications in products and public infrastructures.
The Embedded Computing Conference (ECC) 2026 is coming up – and Arendi AG will be there.
Our technical presentation: "Indoor IoT: Limits of 2.4GHz – and how Sub-GHz overcomes them in practice"
Based on real-world measurements with Wi-Fi HaLow, Wi-SUN, DECT NR+, and Bluetooth Low Energy, we demonstrate why sub-GHz technologies offer clear advantages for indoor IoT in terms of range and building penetration.
We look forward to engaging with the embedded and IoT community.
The Swiss standard SIA 500 “Barrier-free buildings” is currently undergoing a comprehensive revision.
AURACAST in the revised standard “SIA 500” for hearing systems and room acoustics
Hearing systems and room acoustics are becoming increasingly important in Switzerland. The revision is being carried out to meet current technological developments and societal needs. This is being done in a timely manner to take AURACAST into account as an additional aspect.
After years of slow progress, DECT NR+ is finally gaining real momentum.
DECT World 2025 – A Phoenix Rising
Interest and visitor numbers have been growing year after year. Companies across a wide range of industries have recognized the enormous potential of the protected 1.9 GHz frequency band and the unique transmission power of 24 dBm (250 mW), and many have already announced upcoming applications.
Funk & EMV 2026
28.01.2026 | SIX Convention Point, Zürich.
Arendi is at the Radio & EMC trade fair of swissT.net – with a booth and technical presentation.
Many IoT projects have shown that 2.4 GHz is often insufficient within buildings – even with mesh networks, additional routers are needed in each room, and bridging solutions are required across multiple floors. Sub-GHz technologies like Wi-Fi HaLow and Wi-SUN provide reliable coverage with less infrastructure and even offer mesh capabilities.
