Of course the author is going to bash WiFi and Bluetooth - they're promoting the only tech they use, 433Mhz radio. But what about Bluetooth LE ? It's already present in all modern smartphones (iPhone 4s+, all Android flagships from 2013+), works great, the connection lag is less than the 2sec advertised for RF in the article, and was built for the IoT.

The IoT has been struggling to break the surface for a while now, and it's not just the ability to attach a communication and control device to your door lock. It's also your WiFi-enabled TV, sound system, or even thermostat. The IoT is evolving, growing, and doesn't need "saving". Of course the Apple will help, but not for the reasons the author thinks. The real helping hand is coming from iOS 8 and it's Home Kit, bringing a standardized (and user-friendly) way of connecting everything to your phone.

BLE is fine for very short range connections like body area networks, which is what it was designed for, but this is not the IoT for most of us and BLE is not truly an "IoT" technology in any meaningful sense any more than barcodes are an IoT technology. "Works great" is something most IoT developers have never and will never say about BT and due to its limitations, BLE as well. BLE also requires a cloud lookup in most cases so total connection times can many seconds or even minutes.

The IoT needs "saving" from the kind of thinking that says BLE is "all we need" for the IoT, not unlike the early days of TV where radio people said we don't need TV, etc.
