example 1
[0474] Example 1: Company WLAN environment
[0475] Measurements: Each AP makes measurements of its environment. If the AP detects an unexpected noise signal, it forwards the spectrum and sampling data to the WLAN management server, such as the server 1055 in FIG. 1 .
[0476] Classification: At the server, signals are classified based on known signal pulse information. The location of the signal source is determined.
[0477] Policy: The server issues a warning to the WLAN administrator.
[0478] "The interfering signal was detected and identified as a Panasonic cordless phone in room 400."
[0479] Action: The server sends a report (e.g., email, screen pop, etc.) to the administrator, including spectrum analysis plots and graphical location information. Advice to take corrective action can be provided to the network administrator.
example 2
[0480] Example 2: Home WLAN environment
[0481] Measurement, Classification: Similar to above, but in this case AP and STA are used for measurement and classification software is run on a PC connected to the STA.
[0482] Policy: Users are notified via plain language messages on their PCs, but responses are automatic. "The cordless phone is causing interference, click OK to invoke the noise resolution wizard." The "noise resolution wizard" may be a spectral action that will remove the noise effect on the device, such as by moving to another channel or the like. Or, automatically take the correct action and display event summary information to the user.
[0483] Figures 14 and 15 show flow charts (modified from the flow chart shown in Figure 5) that may be used to implement Scenario 1. User assistance tools may be provided by software programs executing on WLAN APs or STAs. In the case of STAs, tools may automate spectrum management actions or controls. In the case of APs,...

Abstract
A system, method, software and related functions are provided for managing activity in a radio frequency band that is shared, both in frequency and time, by signals of multiple types. An example of such a frequency band is an unlicensed frequency band. Radio frequency energy in the frequency band is captured at one or more devices and/or locations in a region where activity in the frequency band is happening. Signals occurring in the frequency band are detected by sampling part or the entire frequency band for time intervals. Signals pulse energy in the band is detected and is used to classify signals according to signal type. Using knowledge of the types of signals occurring in the frequency band and other spectrum activity related statistics (referred to as spectrum intelligence), actions can be taken in a device or network of devices to avoid interfering with other signals, and in general to optimize simultaneous use of the frequency band with the other signals. The spectrum intelligence may be used to suggest actions to a device user or network administrator, or to automatically invoke actions in a device or network of devices to maintain desirable performance.
