Or to put it another way , it's not the power limit of the card alone that defines it's legality but the combination of the card and the antenna. That's prob why, technically, it should only be a qualifed engineer that installs the cards (as presumably they are able to claculate the total eirp and ensure that they are within the limits).
not that it really matters of course  |
I see, thanks, thats cleared that up a bit more.. though from what I can tell all the antenna are standard fitting, I think they are 3Dbi omni (Could be wrong im not very savvy on advanced wireless specs), and from what I can gather most of the mini-PCI cards output is the same due to power restrictions in the laptop itself, so I cant see me having a problem there
