Wireless Transmit Rate
In case a transmitting wireless computer does not receive the
acknowledgment that a transmitted message was received, the station will
try to transmit the message again. If the retransmission fails, your wireless
computer will switch to a lower Wireless Transmit Rate using the Auto
Fallback mechanism.
When working close to each other, two wireless devices will communicate
at the highest transmit rate as supported by both of the interfaces. However,
communications at the highest transmit rate may not travel as far as
transmissions at lower transmit rates.
When moving away from each other, wireless network interfaces will
decrease their transmit rate automatically, but only if required to maintain
the wireless connection. When moving closer to each other again, the Auto
Fallback mechanism will automatically increase its transmit rate again to
the highest possible rate that will provide reliable communications.
For specific information about the range of BG-2000 Wireless Network
Interfaces in different environments, refer to the radio specification section
of this Guide.
