Every ten years, almost to the year, mobile networking reinvents itself. Voice in the eighties, text in the nineties, data at the millennium, smartphones around 2010, and 5G in 2019. The cadence makes the next date easy to predict: 6G, around 2030. But 6G isn't shaping up to be a faster pipe. The framework that defines it — the ITU's IMT-2030, adopted in November 2023 — is less about speed and more about the network learning to perceive : sensing objects that carry no radio, powering tags that carry no battery, covering the planet from orbit. The generations so far competed on connecting things. 6G is the first that wants to notice them. 🔮 The Short Version Six usage scenarios define 6G — three stretched from 5G (broadband, low latency, massive IoT) and three genuinely new: Integrated sensing and communication (ISAC) — the network doubles as a distributed radar, reading its own reflections. Presence, falls, drones, forklifts — detected with no sensor deployed. Ubiquito...

Walk to the far end of your garden and watch your phone's Wi-Fi bars die. Thirty metres and a couple of brick walls — that's the honest range of the network that runs your digital life. Now picture a soil-moisture probe on a berry farm, a full kilometre from the farmhouse, streaming readings over Wi-Fi. No SIM card, no subscription, no mesh of repeaters. Same Wi-Fi family, same IP networking, same WPA3 — just redesigned to go far and sip power instead of going fast. It's called Wi-Fi HaLow — IEEE 802.11ah — and it fills a gap most builders don't realise Wi-Fi left open. 📡 The Short Version HaLow moves Wi-Fi below 1 GHz (902–928 MHz in the US, 863–868 MHz in Europe) and narrows the channels, trading speed for reach and battery life: Range: a kilometre to battery devices routinely; Morse Micro's 2024 line-of-sight record stands at 15.9 km Speed: ~150 kbps up to ~80 Mbps — a hundredth of modern Wi-Fi, and a hundred times most LPWANs Scale: up to 8,192 devic...

You already own a Bluetooth mesh network. You just don't know it. If the lights in your office building dim automatically when the sun comes out, or the LED fixtures in a supermarket report their own energy use back to a dashboard, there's a decent chance a few thousand nodes are quietly relaying messages to each other over Bluetooth right above your head. Not the Bluetooth in your earbuds. Something fundamentally different. 📡 The Short Version Bluetooth mesh is a separate spec, built on BLE's radio but operating nothing like classic Bluetooth. BLE connects two devices — pair, hold a link, talk privately. Bluetooth mesh is a broadcast model: a device shouts, any node in earshot repeats it, that relay is heard by more nodes, who repeat it again. The message floods outward until it arrives. No pairing. No central coordinator. No center at all. The network scales as far as there are nodes to carry it — not as far as one radio can shout. Managed Flooding: The Be...
