Hi,
I have a newbie question. Is it possible to implement a POTS voice quality like an intercom system using Thread (assuming all the end points are using nrf52840 SOC)?.
Thank you.

Hi Albert
250kbps is the on-air bitrate, not the data throughput. In a wireless system the throughput will always be lower than the on-air bitrate, which is why it is approximately 128kbps for thread. I was told the first additional hop would reduce the throughput by a factor of 2, and that additional hops would reduce the throughput a bit more (but not by a factor of 2 for each one).
Like most RF systems thread is simplex, you can only transmit one way at any one time.
The maximum number of router hops is 16. If you include a child node at each end you could get 17 hops in total.
Best regards

Hi Torbjørn,
Thanks of all the answers.

Hi Albert
I am happy to help :)
Feel free to accept my answer if you consider the case closed.
Just add poweramp (+25 dBm IC from Skyworks) and matched external antenna, 3*5/8 with should be enough, it all can give approximately 10 Watts EIRP
