Transmit Rate

The actual data transmission speed of your WaveLAN device is
subject to the following criteria:
■
The type of WaveLAN IEEE cards at both ends of the wireless
link, being:
— The card inserted into your WaveLAN/EC-S device, and
— The card inserted into the WavePOINT-II or,
the peer-to-peer partner in an Ad-hoc network.
■
The communications quality of the wireless link.
■
The user-defined preference for the data Transmit Rate.
The Transmit Rate does not influence the speed at which your
WaveLAN card can receive data messages.
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-6).
In most networking scenarios, you will see that the factory-set
default “Auto” will prove the most efficient. Whenever your
computer communicates via the wireless medium the WaveLAN
interface will:
■
Sense the maximum transmit rate as supported by both
communication partners, and switch to that Transmit Rate.
■
Determine if the communication quality allows for
communicating at this data rate.
Transmissions at lower data speeds are usually more reliable.
Therefore when the communications quality drops beneath a
certain level, the WaveLAN cards will automatically switch to a
lower data rate.
