It depends on the antenna efficiency of course, but I was surprised to discover that BLE modes around 128kbps using coded-PHY have a range extending over 1-1/2 km without a directional antenna. At 2.4ghz its line of sight, of course, but still…
That's extremely surprising to me too. I would have expected BLE to reach a few meters, not kilometers. How can I learn more?
Search for “BLE coded PHY”.
The S8 coded mode with 125kbps rate is the long distance one. Support for it in phones is not widespread, sadly.
Thanks! I didn't realize that was the key phrase.
