What was discovered
A formula that sets the maximum capacity of a communications channel with Gaussian noise as a function of its bandwidth and signal-to-noise ratio, developed by Claude Shannon building on earlier work by Ralph Hartley at Bell Labs.
What it led to
- Design of modern digital communication systems
- A theoretical reference limit for modems and wireless networks
- Basis for error-correcting codes that approach the Shannon limit
- Foundation of contemporary telecommunications engineering
