ASUS USB SpaceLink Client

Chapter 3 - Reference

Chapter 3

3.6.3 Monitor

Directed link state test with one wireless network, including:

•

SNR: This indicates the quality of communications within the current
network. The communication quality is based on signal level and noise
level measurements. In principle, the higher the SNR, the better your
communications quality.

•

Communication Quality: Specifies the Communication Quality of the
Basic Service Set to which the station is currently connected to.

•

Signal Level: Specifies the Average Signal Level of the Basic Service
Set to which the station is currently connected to.

•

Noise Level: Specifies the Average Noise Level of the Frequency Chan-
nel currently used for communications.

•

Throughput: This sends a specified number of data packets to the re-
mote host and calculates the average megabytes per second.

During the test, the Start button toggles to Stop. You can click Start button
to begin the link test and click Stop button at any time to terminate the test.
