Other Wireless Standards (For Reference)
| Wireless Standard | Frequency Bands | Maximum Data Rate | Features | Advantages |
|---|---|---|---|---|
| Wi-Fi 6 (802.11ax) | Operates on both 2.4 GHz and 5 GHz, with support for 6 GHz (Wi-Fi 6E) | Up to 9.6 Gbps | Improved MU-MIMO, OFDMA, better efficiency, and capacity | Enhanced performance in dense environments, higher throughput, and lower latency |
| Wi-Fi 6E | Extends Wi-Fi 6 into the 6 GHz band | Similar to Wi-Fi 6, with potentially higher speeds due to less congestion | Same as Wi-Fi 6, with the addition of more channels in the 6 GHz band | More available spectrum, reduced interference, and higher performance |
This table provides a clear comparison of the Wi-Fi 6 (802.11ax) and Wi-Fi 6E standards, highlighting their frequency bands, maximum data rates, features, and advantages.
Specific Use Cases and Standards
- For Streaming Videos: Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) are preferable due to higher throughput and better performance in handling multiple devices.
- Limiting Possible External Interfaces: Using 802.11g, 802.11a, or 802.11b might be more suitable for environments that require restricted connectivity due to their older technology and lower data rates compared to 802.11n (Wi-Fi 4) and 802.11ac (Wi-Fi 5).
Summary
- Wireless standards 802.11a, 802.11b, 802.11g, and 802.11: These are older standards, each operating on different frequency bands and offering varying data rates, with 802.11a and 802.11g supporting higher speeds compared to 802.11b.
- Best for Streaming Videos: Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) due to their higher speeds and advanced features.
- Operating on Both 2.4 GHz and 5 GHz: Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) (some devices) support dual-band operation.
