A web viewer for RF spectrum data

This project complements Spectrum Tools with a web viewer for spectrum data.

Both live and historical spectrum captures can be viewed. Data is captured by the spectool_raw program.

Typical uses:

• Wireless site surveys.
• Monitoring wireless spectrum usage.
• Diagnosing wireless problems after the fact.

Spectool Web Viewer has a small footprint and is ideal for embedded or resource-constrained systems. With the live capture feature disabled it operates as a static site.

Usage

Quick start:

make
make serve-static

This will let you view historical captures.

To import your historical spectool_raw log files, copy or symlink them into htdocs/data/, run make again, and refresh the page.

To see live captures as well, make sure you have all the requirements below, then run:

make
make serve-full

Requirements

For viewing historical captures on a static page, you need:

• GNU make
• python or an HTTP static file server of your choice

For the live view, you additionally need:

• spectool_raw(1) from Spectrum Tools
• tcpserver(1) from ucspi-tcp
• tai64n(1), svscan(1) and supervise(1) from daemontools
• openssl(1) from the OpenSSL project

To capture spectrum data, you'll also need spectrum analyzer hardware such as the WiSPy or the Ubertooth.
