> Narrower bandwidth opens exponentially more channels, allowing organizations to communicate without the congestion of legacy radio systems

## Key points

- 6.25 kHz channel bandwidth provides exponentially more channels than legacy 25 kHz or 12.5 kHz systems
- Icom and JVC Kenwood co-developed the NXDN™ protocol to enable next-generation digital narrowband communication
- The FCC has progressively mandated narrower bandwidths to alleviate electromagnetic spectrum congestion

This video from [Icom](https://marketscale.com/shows/icom/) highlights the advantages of 6.25 kHz channel availability. The video explains the Federal Communications Commission's (FCC's) regulation of the use of the electromagnetic spectrum, transitioning from 25 kHz to 12.5 kHz to alleviate congestion. **Icom**, in collaboration with **JVC Kenwood**, introduced the next-generation digital narrowband ([NXDN™](https://icomuk.co.uk/What-is-NXDN/4054/793/)) protocol that operates on 6.25 kHz, offering over a thousand additional channels.
