2.3 Operational Considerations

To make your WLAN deployment process as smooth as possible, you should consider more than just the distribution and
installation of access points. You should also consider how you will manage, optimize, and troubleshoot your WLAN after
deployment.

2.3.1 Tuning

Approach building an enterprise WLAN with the same life-cycle approach you would apply to a wired network. After you deploy
the WLAN, revisit key network engineering processes to account for changes in the environment. Watch for access points that are
overloaded or are underused, and check for potential dead spots. Furthermore, be aware that the likely points of failure can
change as the environment changes. For example, a neighboring business might install access points that cause RF interference on
your network. You should schedule and perform periodic walkthroughs to ensure that the design goals of the wireless network
continue to be met. The SmartPath EMS VMA provides quick views into how the network is behaving, which SmartPath APs are
the most heavily loaded, and which have the most clients.

2.3.2 Spectrum Analysis

Black Box SmartPath APs have the ability to perform spectrum analysis in both the 2.4-GHz and 5-GHz band. Spectrum analysis
provides a live view of the RF environment so that you can plan for further WLAN deployment or troubleshoot WLAN issues such
as high retransmission rates caused by device interference or slow connections from overuse.
There are two main spectrum analysis functions: the graphical rendering of the RF environment in an FFT trace and swept
spectrogram, and the identification of interference devices such as cordless phones, microwave ovens, video bridges, and
Bluetooth devices. The SmartPath APs that support each of the spectrum analysis functions are listed in the following table:
