Enjoy the satisfaction of a nearly

perfect WLAN implementation.

Chanalyzer turns data collected from a Wi-Spy into highly interactive charts and graphs, allowing

users to visualize their wireless landscape. Chanalyzer, combined with a wireless network card, can

also display available access points as they appear in the spectrum, giving quick insight into whether

interference is Wi-Fi or non-Wi-Fi related.

Together, Wi-Spy and Chanalyzer enable both enterprise and small business users to visualize,

troubleshoot, and optimize WLANs. MetaGeek products are affordably priced to allow everyone, from

individuals to large teams, access to professional-grade wireless spectrum analysis hardware and

software.

What is a Wi-Spy?

A Wi-Spy is a portable USB spectrum analyzer, similar to a cable tester, but for wireless. It displays

all radio energy in a frequency range, such as the 915 MHz, 2.4 GHz or 5 GHz public spectrum. Unlike

a Wi-Fi card, the Wi-Spy is a fine-tuned piece of hardware that shows non-Wi-Fi activity emanating

from devices like microwave ovens, automation systems, bluetooth, cordless phones, wireless security

cameras, or anything else operating wirelessly in those frequencies. It also helps users determine a

viable channel for network communications.

What is Chanalyzer?

Chanalyzer turns data collected from a Wi-Spy (and a wireless network interface card) into charts and

graphs that will help users determine if they are experiencing interference. With a wireless network

card, Chanalyzer displays available access points. With a Wi-Spy Wi-Spy, its data can be found in the

Density, Waterfall and Channels Table views while network data from the wireless network card can be

found in the Networks Table and Networks Graph. If you are running Chanalyzer in a virtual machine,

like VMWare, you will need an additional USB Wi-Fi adapter to see specific network information.

Choose a Wireless Network

Interface Card (NIC)

Select a built-in or connected wireless network card in the main menu to access additional

WLAN information about SSIDs, RSSI, MAC address and data rate. Click Wi-Fi in the menu

bar, and then your wireless network card to collect Wi-Fi data in conjunction with the

spectrum data.

*Wi-Spy is a spectrum analyzer. It is not capable of reading at the Wi-Fi packet layer.

Therefore Wi-Spy will not appear in the Wi-Fi card drop-down list.

Occasionally a wireless network card will actively perform probe requests on all Wi-Fi

channels, creating noise across the entire band with power levels above -40dBm. This

background activity can often skew results of a spectrum analysis site survey. If you notice

this behavior with your wireless network card and don't want the additional noise in your

recording, we recommend that you select No Wi-Fi Scanning .

See Wi-Fi Channels label on the Density View

In the main menu select View > Wi-Fi Channels . This will change the x-axis to display the

Wi-Fi channels instead of the corresponding spectrum frequencies.

Navigation Pane

The Navigation pane provides controls for browsing Wi-Spy / Wi-Fi capture sessions or

recordings. Within the Navigation Pane, you'll find:
