Wi-Fi typically operates on two main frequency bands: 2.4 GHz and 5 GHz. Some newer Wi-Fi standards, like Wi-Fi 6E, also utilize the 6 GHz band, increasing the number of available channels and potentially reducing congestion. Therefore, you could say Wi-Fi primarily uses three frequency bands: 2.4 GHz, 5 GHz, and 6 GHz.
In contrast, wired internet connections, such as those using Ethernet cables, do not operate on frequencies in the same way that wireless technologies do. Instead, wired connections transmit data over physical wires. Ethernet standards (like 10BASE-T, 100BASE-TX, or 1000BASE-T) operate at specific speeds and methods rather than defined frequencies. Ethernet cables can carry data at various speeds (from 10 Mbps up to 10 Gbps and beyond), but they do not utilize frequency bands like Wi-Fi does. Instead, they use different signaling methods over the copper or fiber optic medium.
In summary:
- Wi-Fi: Typically uses 2.4 GHz, 5 GHz, and sometimes 6 GHz bands.
- Wired Internet: Does not operate over frequency bands in the same way; uses physical medium to transmit data.
