Method and system for aggregating WiFi signal data and non-WiFi signal data |
摘要 |
Methods of aggregating spectrum data captured from a narrowband radio to form a spectrum covering a much wider frequency band. Frequency data, such as FFT spectrum data captured from a narrowband receiver such as an IEEE 802.11 Wi-Fi receiver are combined to display representative real-time FFT, average FFT, and FFT duty cycle data of a wideband spectrum. Data is captured from narrow band radios such as access points, station monitors, or client devices on a wireless network. A wideband spectrum may be aggregated from data captured from one or from multiple devices. Data may be stored for later analysis and display. |

1. A non-transitory machine readable medium storing instructions which, when executed by one or more hardware processors, causes performance of a set of operations comprising:
accumulating frequency-domain samples from a radio scanning a plurality of channels, the scanning generating a plurality of the frequency-domain samples for each of the plurality of channels; categorizing the frequency-domain samples as either Wi-Fi samples or non-Wi-Fi samples; for each of the plurality of channels:
selecting a first sample from among the Wi-Fi samples of the plurality of frequency-domain samples that correspond to the respective channel;selecting a second sample from among the non-Wi-Fi samples of the plurality of frequency-domain samples that correspond to the respective channel; andchoosing a representative sample for the respective channel from among the first sample and the second sample based on a weighting parameter and respective signal strengths of the first and second samples; and combining the representative samples of all of the plurality of channels to produce a spectrum display representing a combined spectrum across all of the plurality of channels. |
