(Cableless realtime transmission for audio)

Wireless realtime audio

This project should lead to the development of a wireless realtime audio transmission unit.

Goals:

At least 16bit audio at 44100Hz
Latency under 5ms
Battery operation for more than 5hr
Configurable input type
The range over 20 meters at the plain field

Possible solutions:

Transciever SR1010

transcever SR1010
It could be difficult to get samples because it was introduced a few months ago.

TI CC8520

CC8520
Latency less than 20 ms - may be unusable

TI CC1312

CC1312
48MHz ARM Cortex M4F with 868MHz transmitter Data transfer - 1 Mbps (although the data sheet specifies data output up to 4 Mbps)
