Huawei’s Wi-Fi 7 implementation for Mate 70 series is missing key features
Huawei’s official specifications for the Mate 70 series of smartphones do not reveal anything in terms of the phones 5G capability but offer several details about the available air interfaces. The “triple-network”* satellite connectivity available on Mate X6 and the UWB interface available for Mate 70 RS together with the ubiquitous now NearLink protocol and Lingxi Communication System (2nd generation) are opening the stage for the introduction of Wi-Fi 7, a first for the Chinese smartphone OEM.(*) BeiDou BDS-3, Tiantong-1 and a LEO constellation whose services will commence in H2 2025. No 3GPP NTN yet, just D2D (Direct-To-Device)
It’s surprising that Huawei phones jumped from Wi-Fi 6 to Wi-Fi 7 (although BT is still version 5.2) and even more surprising is that the 6 GHz band is missing from the Mate 70 specification. A quick inspection of the listed specifications for Mate 70 shows several limitations which makes this Huawei version of Wi-Fi 7 more like a repackaged Wi-Fi 6.
In this table I have singled out the differences between 802.11 be (Wi-Fi 7) and the Mate 70 Wi-Fi 7 specifications. As with the Lingxi system, maximum performance is obtained using the recommended Huawei Wi-Fi 7 APs. With only three 160 MHz channels, no 6 GHz band and 1024 QAM instead of 4096 QAM this Wi-Fi implementation of OFDMA negates most of the Wi-Fi 7 advantages. This phone will have a hard time keeping up with true Wi-Fi 7 capable smartphones.
Still works pretty good. Wifi 6 is fast enough for everything.Huawei’s Wi-Fi 7 implementation for Mate 70 series is missing key features

Now why don't you post something on Huawei's satellite phone coverage, which other phones don't have? Which is actually revolutionary and so helpful?
Oh right because that would be positive news for china, and you wouldn't want that.
It's important to note where it comes up short. Huawei's achievements are very impressive considering the tech embargo.
We are bombarded with where Huawei come up short, or could possibly come up short on a daily basis. Which happens a lot more than celebrating their achievements.
This particular poster certainly perpetuates it, unabashedly so. Hence my response to their post.
Huawei is certainly aware of their deficiencies more than we do. But doesn't mean we can't respond back to certain people constantly posting such negative and often times misinformed news.
TechInsights really failed at basic professionalism. How is it surprising a Chinese wifi7 phone has no 6ghz support when the Chinese Wifi7 standard doesn't have 6ghz as part of the spec? It is ILLEGAL in China to sell wifi7 routers with unlocked 6ghz support.
Not just China, 6GHz is illegal in many other countries for WiFi use. TechInsights, being a market intelligence company would surely know that. Usually they are unbiased in most of their reports, but given how much money is available in the west for anit-china propaganda, it would be hard for a company like that to stay completely neutral. Lately some of the stuff they do indicates they have given in to the western propaganda machine in some way.
Regulations Enabling 6 GHz Wi-Fi

i know what you are trying to say .. XD
this time Techinsight completely failed. they purposely ignore the fact ''6GHz is illegal in many other countries for WiFi use so does in China'' still they pretend. oh Mate70 is missing key feature. bla bla bla
and for your kind information, Kirin 9020(7+nm) performance is as good as TSMC 4nm/5nm that's coz of Hisilicon design capability.
Guansheng Semiconductor Production Base has started construction!
On December 13, the groundbreaking ceremony of Guansheng Semiconductor Technology (Hefei) Co., Ltd. was held in Hefei, marking a solid step forward in the company's development in the semiconductor field.
As a well-known enterprise in the industry, Guansheng Semiconductor Technology has been committed to the research and development and innovation of semiconductor technology. The construction of a new production base in Hefei fully reflects the company's firm confidence and strategic layout for future development.
The new base of Guansheng Semiconductor Technology (Hefei) Co., Ltd., which broke ground this time, will use advanced production equipment and technology to build a world-class semiconductor production base. The construction of this base will not only provide a strong impetus for the company's development, but will also make positive contributions to the development of the semiconductor industry in Hefei and even the whole of China.
