WinXP Antenna Diversity setting?

mrburch · 06-11-2003

I have a Dell Inspiron 8200 with the Truemobile 1180 internal NIC. I noticed in the Properties\Advanced tab a Property for Antenna Diversity with options of Default, Enabled, or Disabled. What exactly does that setting do and what is the antenna setup for the mini pci 1180?

you might want to open up the dell and check as my buddy's company is bid on dell and none of his laptops have anything connected to the antenna ports on the mini-pci cards in them.

general explanation of "diversity"

You'll notice that lots of access points, and some cards (like the Cisco) have 2 antennas. These antennas aren't used at the same time. The radio rapidly switches between the two to find the strongest signal. What happens is that the radio waves bounce around on things and you get what is call "multipath interference" (like ghosting on non-cable televisions). A small distance change in antenna placement can lessen or eliminate multipath interference and that is what antenna diversity attempts to do.

i've also got an 8200 with the (broadcom) 1180 internal mini pci card.

the 1180 card has 2 ports, for 2 antenas. the dell 8200 only has 1 ant. it does not matter which port you connect to, because if you enable diversity, it will select the port with the best signal.
