To be fair, such devices would prefer 2.4Ghz any other Wi-Fi frequency cries at a view of a single wall.

- zamadatix 3y agoThis is the type of device where 802.11ah (recently popular on the front page again) or LoRa is killer. Unless you need your ESP32 to push 10s of Mbps all the time you can instead use something which punches through multiple walls with ease, doesn't compete with high speed devices, and has power saving things like TWT years ahead of high speed Wi-Fi standards.
- 0x457 3y agoYes, but (nearly) every potential buyer of IoT device has 2.4Ghz WiFi network at the location that said IoT will be deployed. LoRa will require some kind of bridge device, and since we can't agree on anything - each vendor will have their own bridge device. Alternatives like Amazon Sidewalk and Helium could work, but: - Helium means users will pay for traffic to someone and use someone's internet connection. Doubt it will fly. It would be cool in a post-apocalyptic world, though. - Amazon Sidewalk isn't universal and, IMO, immoral (enabled on devices by default without informing the owner of the device). Good luck downloading updates to your light bulbs at 80Kbps.
