Noise and Verification of Network Operability

Noise plays a major role in network reliability and the quality of service. If there is significant noise in a
particular region of the network, the quality of service is likely to be worse in that region than in other
regions. By using Summit WMScanner's noise visualization capability, you can quickly identify regions
of high noise. You can use tooltips to identify the precise channel where the noise is located. If an access
point is in an area that has high noise in a specific channel, Extreme Networks recommends selecting an
alternative channel for that access point.

Hybrid Network Overlap Visualization

The Hybrid Network Overlap visualization allows you to view the deployment type of the entire network.
This visualization shows areas of coverage where the clients are served only by 802.11 A\B\G (Legacy)
APs, only 802.11 N APs (High Throughput) APs or all 802.11 A\B\G\N (Hybrid) APs. Network
planners can use this view to determine where clients can get potentially better performance because of
the presence of 802.11 N APs. This visualization also allows network planners to determine the location
where legacy equipment is hindering 11n design.
The following is an example of Hybrid Network Overlap visualization. Hovering the mouse over the
grid vertices displays the data at particular points in this visualization
