I have battery operated application, in which I have to transmit data at 4Khz.

Each sample contain 32x9 = 288bits.

Is there any wireless IC/module which can tranfer 4Khz samples with each sample having 288 bits at very low power. i.e

4Khz x 288 = 1152000 bits/sec

 

That is going to take spread-spectrum in the GHz range...

 

How low is "low power" and how far do you want to transmit the data?

 

Transmit range is 10m. harsh environement . temperature low as -30C.

Should be 1 year capable of sending data with 13.2Ah battery.

 

Class 2 bluetooth ?
