This really make a lot sense, we have seen some AP or PCMCIA card rated at 50 mW or above (only the cards with first generation Intersil chip limit power to around 30mW) but the receiving sensitivity is unknown. While some card with low power output gets better range such as Orinocol. There should be a way to identify the absolute performance of a card based on both TX and RX. This way we users could find out who is the real performer.
