Well, the two different power levels appear to different throughput's, only 6 and 54Mbps. If it was because of turbo-mode, I believe it would appear at data rate of 108 Mbps, for example.
The thing that must change between throughput's it's the modulation. The "basic" modulation give us smaller throughput's, and the more complex better throughput's. The sensitive has to do with the modulation... since the simpler/basic modulation it's more robust, the receiver can decode until smaller received power. When using more complex modulations, like OFDM for 54Mbps in 802.11a and b, it must receive a better signal to decode correctly. My theory it's that at higher output power, the transmitter hardware will produce such interference that will prejudice the generated signal. So, because the higher throughput generated signal is complex and sensitive, it must be used a lower power output. Does this make any sense?
Thank you for the paper. I'll read it!
Best regards,

Output power varies with transmission throughput: why? 
Linear Mode
