The secondary indicator for wireless performance is the Data
Throughput Efficiency of the radio connection. Data Throughput
Efficiency is measured in:

When communicating with another wireless IEEE 802.11
compliant LAN device, both devices will automatically
synchronize their data rate to the highest compatible transmit
rate.

As data communications at lower speeds may travel larger
distances that communications at high speed, the WaveLAN
adapters will automatically switch to a lower data rate when
one or both of the two link partners are moving away from one
another.

NOTE:
When running a network with multiple types of WaveLAN
PC Cards, all communications between the different types
of PC Cards will be at the Standard speed (see “About
Using Different Card Types” on page 1-7).

When running the WaveMANAGER/CLIENT Link Test, the
diagnostic tallies will inform you at which speed the both Link test
partners synchronized their data transmissions.
