You're asking about the reasons behind channel restrictions on 2.4GHz networks, especially in North America. It seems your teacher mentioned some limitations that aren't immediately obvious. Let's break it down:
- **Channel Availability**: Channels 12–14 are blocked in many regions, including North America.
- **Regional Differences**: In Japan, channel 14 is available, but only on older 802.11b routers.
- **Technical Constraints**: These restrictions often stem from interference and spectrum management rules.
These rules help prevent signal overlap and ensure better network performance. If you're curious, you can explore how different countries manage their wireless channels for more insight!
It might be incorrect; further investigation is required.
This could relate to the frequency bands used by the channels.
The various channels each relate to a marginally distinct frequency within the 2.4GHz spectrum. They are arranged with some separation to avoid conflicts between devices. The signals from channels 12, 13, and 14 are too near restricted US frequencies, which is why they’re omitted to minimize interference from those areas.
Essentially, the main channels are disabled to prevent disruption from the band above the Wi-Fi spectrum used.
It's clear from the view that channels 12 and 13 aren't helpful since they'd intersect with channel 11.
