Spectrum Miner and Data Analysis for the National Radio Networking Research Testbed

Spectrum Miner Architecture

Spectrum Miner Architecture

The Spectrum Miner application

• Automates collection of spectrum data
• Creates analyzer and antenna profiles for various test cases
• Interfaces with spectrum analyzers and Agile Radio under development

Algorithm : Usage of a channel over 1 day :

Let the frequency band be F1 = f1 Hz – f2 Hz

• Run a test over F1 for a duration of 24 hours
• Display intensity plot showing the spectrum analyzer output

as a function of time and frequency .

• Study plot obtained in step 2 . Determine the part of F1

being utilized .Let this bandwidth be F2 = f3 - f4 Hz. Repeat

Steps 1-3 for 7 days in the week to arrive at a more reliable

estimate of F2 .

• Run a new test over F2
• Choose a frequency channel within F2 and display its

Probability Density Function .This plot gives an idea about

the channel utilization .

• VERY STRONG SIGNAL PRESENT AT 91.5 MHZ
• WEAKER SIGNAL AT 90.69 MHZ . REST IS MOSTLY NOISE
• SIGNAL PRESENT MUCH MORE FREQUENTLY THAN NOISE AT

91.5 MHZ

• INFERENCE : CHANNEL 91.5 MHZ EFFICIENTLY UTILIZED
