Monitoring WaveLAN Performance
WaveLAN Link Test
5-12 WaveLAN IEEE 802.11 PC Card User’s Guide
■ Another station is suffering from a “Poor” communications
quality, and consequently sending many retransmissions
■ Numerous frame collisions occur due to a “hidden station”
problem.
You are advised to run the WaveMANAGER/CLIENT Link Test
from multiple stations to determine whether:
■ This problem is a local problem, i.e. for one station only, or
■ This problem is experienced by all stations.
When all stations suffer from poor Data Throughput Efficiency,
despite a “Good” SNR value, investigate what is causing the heavy
traffic load.
