Monitor Information
• Noise (dBm): The strength of the noise detected at the receiver reported in dBm (decibels referenced to
1 milliwatt). The displayed value is the running average since the start of the test and is reported as a negative
number. Noise can interfere with the received signal so a smaller noise value corresponds to a stronger link.
For example, a noise level of -95 dBm is more desirable than a noise level of -89 dBm. The bar graph displays
the relative strength of the noise level (a shorter bar represents a weaker noise level and is more desirable
than a longer bar).
• 11 Mbps (pkts): The number of packets received at the 11 Mbits/sec transmit rate since the start of the Link
Test. In general, most packets will be received at the 11 Mbits/sec rate if the devices have a strong link.
• 5.5 Mbps (pkts): The number of packets received at the 5.5 Mbits/sec transmit rate since the start of the Link
Test.
• 2 Mbps (pkts): The number of packets received at the 2 Mbits/sec transmit rate since the start of the Link
Test.
• 1 Mbps (pkts): The number of packets received at the 1 Mbits/sec transmit rate since the start of the Link
Test.
