Receive sensitivity (RX) spec for our 1-watt card is -85dBm for 802.11b mode: This is 3x the transmit power (TX) figure for the Alfa AWUS036H (500mw G-version): That TX figure is 28dBi. I’m trying to verify that TX is the important figure in which the range limitation would occur: that range limitation would not occur with RX: Because the RX of the new realtek card is triple the TX figure of the Alfa card.
So far I have not been able to find any “official” technical papers that would disprove this: I have found supporting information in a document from one of our customers who is very tech savvy: He says that what I’m stating above is correctre. TX being the limiting factor.
ps. I already have a 24 dbi grid antenna and 2 bi-quads
or maybe is there a way to power the units with external power supply to get a little more power?
