Does anyone have a list/table of minimum SNR for Auto Rate Fall Back for 802.11 b and n modes
I'm doing a Uni paper at the moment on omni antenna gain and want to add some context to different 'gain' omni antenna's(2,3,5,9,15dBi) vs performance.(I'v already done some real world tests today around the yard/house!)
Ideally I'd love the math formula to work those details out for myself (Anyone?).
Currently I have found :
802.11a ( Found : http://www.cisco.com/c/en/us/td/docs/wireless/technology/mesh/7-3/design/guide/Mesh/Mesh_chapter_011.pdf )
Data Rate | Minimum Required SNR required dB
54,31
48,29
36,26
24,22
18,18
12,16
9,15
6,14
802.11g ( Found : http://www.dd-wrt.com/wiki/index.php/Index:FAQ )
Data Rate | Minimum SNR
6 Mbps 8 dB
9 Mbps 9 dB
12 Mbps 11 dB
18 Mbps 13 dB
24 Mbps 16 dB
36 Mbps 20 dB
48 Mbps 24 dB
54 Mbps 25 dB
