Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Smart home accessories typically need a guaranteed 2.4GHz Wi-Fi connection. Many Wi-Fi routers let you join both bands under the same SSID (network name).

An AIoT Framework With Multimodal Frequency Fusion for WiFi-Based Coarse and Fine Activity Recognition. IEEE Internet of Things Journal, 2024; 11 (24): 39020 DOI: 10.1109/JIOT.2024.3400773 ...

Well, probably not. Here’s a look at why 2.4GHz Wi-Fi is so ubiquitous in today’s smart home, how we can learn to live with it, and whether there are better solutions out there.
