- Channel width: This refers to the amount of frequency spectrum a channel occupies, usually measured in MHz.
- Channel overlap: Adjacent channels may overlap, potentially causing interference if not managed properly.
- Channel capacity: The amount of data that can be transmitted over a channel within a given time frame.
Here’s a comparison of the main frequency bands used in Wi-Fi networks:
| Characteristic | 2.4 GHz Band | 5 GHz Band |
|---|---|---|
| Number of channels | 11-14 (varies by region) | Up to 45 (varies by region) |
| Channel width | 20 MHz | 20, 40, 80, or 160 MHz |

Wi-Fi 6E and the 6 GHz Band
Wi-Fi 6E takes things a step further by expanding into the 6 GHz frequency band. This addition brings a wealth of benefits to Aruba wireless channel availability:
- More available channels: The 6 GHz band offers up to 59 non-overlapping 20 MHz channels or 14 non-overlapping 80 MHz channels.
- Reduced interference: The 6 GHz band is currently less crowded, leading to cleaner signal transmission.
- Higher throughput: Wider channels in the 6 GHz band allow for increased data rates.
Here’s a comparison of channel availability across different Wi-Fi standards:
| Wi-Fi Standard | Frequency Bands | Number of Non-Overlapping Channels |
|---|---|---|
| Wi-Fi 5 (802.11ac) | 2.4 GHz, 5 GHz | 3 (2.4 GHz), 24 (5 GHz) |
| Wi-Fi 6 (802.11ax) | 2.4 GHz, 5 GHz | 3 (2.4 GHz), 24 (5 GHz) |
| Wi-Fi 6E | 2.4 GHz, 5 GHz, 6 GHz | 3 (2.4 GHz), 24 (5 GHz), 59 (6 GHz) |
As Aruba continues to integrate Wi-Fi 6 and 6E capabilities into their product lineup, users can expect significant improvements in channel availability and overall network performance.
