Voice over 6lowpan

1. Do you intend to do live voice transmission or just transmit voice file offline?
2. Do you mean to have 800-1000 meters for voice transmission and other signals?

1. I intend to do live voice transmission
2. Yes. I have 800 meters between my body sensor and gateway.

1. According to my experience, 6lowpan is not suitable for voice streaming due to its low data rate.
2. According to my experience testing on Contiki 6lowpan, the line of sight test never exceeds 150 meters.

Oh, ok. Thank you.
What's module or technology i can use for solution of that task?
