What is the Wi-Fi 7?
In recent years, new applications have increasing requirements for the throughput and latency of Wi-Fi , and Wi-Fi 6 can't fully meet these needs.
Therefor, the IEEE 802.11 Standards organization is about to release a new revised standard IEEE 802.11be EHT, namely Wi-Fi 7.
Wi-Fi 7 (IEEE 802.11be) is an upgraded version of Wi-Fi 6 (IEEE 802.11ax), also known as Extremely High Throughput (EHT).
What are the new features of Wi-Fi 7 compared to Wi-Fi 6？
New and enhanced main features:
On the basis of Wi-Fi 6, Wi-Fi 7 introduces technologies such as 320MHz bandwidth, 4096-QAM, Multi-RU and Preamble\Subchannel Puncturing, Multi-link Operation , enhanced MU-MIMO, Multi-AP Operation , which has higher data transmission rates and lower latency compared to Wi-Fi 6. 802.11be can support three frequency bands sush as 2.4GHz, 5GHz, and 6GHz simultaneously, and which is compatible with 802.11a/b/g/n/ac/ax.
Test items for Wi-Fi 7：
CE:
EN 300 328 V2.2.2
EN 301 893 V2.1.1
EN 303 687 V1.1.1
* Note：It was evaluated in the context of Partial_RU Power < Full_RU Power. Partial_ RU selects the RU near the edge of the bandwidth for testing.
FCC & ISED :
15.247 / RSS-247 Issue 2
15.407 / RSS-247 Issue 2 (Wi-Fi 5G)
15.407 / RSS-248 Issue 2 (Wi-Fi 6E)
* Note：It was evaluated in the context of Partial_RU PSD < Full_RU PSD. Partial_ RU selects the RU near the edge of the bandwidth for testing.
JRL:
MIC Article 2 paragraph 1 Item 19
MIC Article 2 paragraph 1 Item 19-3
MIC Article 2 paragraph 1 Item 79/80
* Note：It was evaluated in the context of Partial_RU Power < Full_RU Power. Partial_ RU selects the RU near the edge of the bandwidth for testing.
