Transmit Rate 4
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 computer, 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.
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.
The Auto Transmit Rate Select Mechanism 4
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:
■ 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.
