Setting the scene
Ericsson-driven engineering traded power for convenience on the 2.4 GHz band, eventually colliding with microwave ovens and Wi-Fi.
What happened
Pairing rituals—discoverable modes, PIN codes—aged poorly until BLE simplified wearables.
Why it still matters
Logo runes reference Harald Bluetooth uniting Denmark narratives, a branding flex for spec sheets. Memorable detail: early USB Bluetooth dongles looked like gum sticks sticking out of laptops.
Background
Bluetooth uncluttered desk cables for keyboards, earbuds, and car kits before Wi-Fi handled heavy throughput.
