Mmm.so is it 150mbps per antenna, I get 2 antennas equals 300 as both are 150 each bit 3 antennas is 3x150 and that equals 450 not 600?Īlso I don't understand if I up the mhz from 20 to 40 it will overlap, can you please explainīasically, very simply, you should always use non-overlapping channels in a 2.4Ghz set up. Ok so if I have 3 antennas I could have up to 600mbps but as its only 2 300mbps Whether you can get the best from it, depends on the equipment you are using (and obviously on all the other variables, such as distance, objects, walls, etc.) However, this is highly NOT recommended, since it leaves you with only 2 non-overlapping channels (instead of the usual 3), interfering with all the other wireless networks in the neighbourhood.Ĩ02.11n doesn't tell you the max speed, it tells you the standard in use. Total =600 Mbps.Īs I explained before, with the card in the link, 300 Mbps as max speed is only achievable if you set the bandwidth to 40 Mhz instead of 20 Mhz (roughly doubling it), as this card only has 2 MIMO antennas. The maximum speed is actually 600 Mbps, and this is obtained with the maximum single speed in a 40 Mhz channel mode, which is 150 Mbps, times 4 MIMO streams, which is the maximum 802.11n can have. Why? Interference/distance/objects between devices, etc. 300 mbps is the maxium theoretical limits of N, you're not going to get that speed.
