How many non-overlapping channels does the 5GHz band support?

The correct answer reflects the capacity of the 5GHz band to accommodate numerous non-overlapping channels, which can enhance wireless network performance by alleviating congestion. Specifically, in many regions, the 5GHz band can support up to 23 non-overlapping channels. This is significant because these channels can be utilized simultaneously without interference, allowing for better throughput and reduced latency compared to the 2.4GHz band, which has fewer non-overlapping channels and is more prone to interference from various devices like microwaves and Bluetooth devices.

Understanding the distribution and utilization of these channels is essential for network planning and optimization, especially in densely populated areas where multiple networks may compete for bandwidth.
