The user-defined preference for the data Transmit Rate.
NOTE:
Transmissions at high data rates do not cover the same
distances as wireless data transmitted at Standard or Low
data rates (see Table A-4 on page A-5).

When upgrading from standard WaveLAN cards to Turbo
cards, you may need to perform a site survey again to
verify that the entire coverage area allows for data
transmissions at the highest transmit rates.

In most networking scenarios, you will see that the factory-set
default “High” will prove the most efficient. Whenever your card
communicates via the wireless medium it will:
