The goal of this project is to create a wireless audio link with highest audio quality that is possible given the bandwidth and coexistence lim- itations of RF-link, and encoding and decoding capabilities of a modern low cost microcontroller that is present on each side of the link. Radio Link for two way audio transfer will be studied in this report. To analyse and implement a method for transferring two way audio using radio solutions from Nordic Semiconductors will be the main issue to discuss. Maximizing a sustainable data rate with strict latency and RF-coexistence requirements will be the key challenge.
