Noise Ratio

[sven_muermans]

Hi, during the exam for Wireless Specialization I got the following question "What is the minimal acceptable Signal to Noise Ratio when surveying at 11Mbps?"

Can someone provide me with the answer, I tell me this is the answer?

I' ve got four possibilities

1) 4dB

2) 6dB

3) 10 dB

4) 12 dB

Thanks for your help.

I believe the minimum SNR for 11Mbps is 10 db. I cant’ remember where I saw this number though. Sorry.
