Shulou(Shulou.com)11/24 Report--

CTOnews.com, Oct. 10, with the upcoming release of Intel Core 14-generation desktop processors, motherboard manufacturers are launching new Z790 motherboards, most of which are equipped with the latest Wi-Fi 7 wireless network cards.

Although the Wi-Fi 7 standard has not yet been finalized, Intel's BE200 Wi-Fi 7 controllers have been shipped in large quantities and are in short supply.

@ ghost_motley found that Intel BE200's delivery time on Mouser, a major chip distributor, has been extended from six weeks to 12 weeks, which may explain why some manufacturers have chosen the Wi-Fi 7 solutions of Qualcomm and MediaTek.

According to Mouser, the factory delivery time for Intel BE200 Wi-Fi 7 NICs is 12 weeks, and the price of each module is 18.53 euros (CTOnews.com Note: currently about RMB143), but the unit price can be reduced to 15.42 euros (currently about RMB119) if you buy 500 or more.

Intel has released two M.2-2230 network cards based on Wi-Fi 7 draft, BE200 and BE202, which are compatible with 2x2 TX / RX streams and support 2.4GHz, 5 GHz and 6 GHz bands. Among them, the highest speed of BE200 is 5 Gbit / s, which is lower than the standard transmission rate.

Although the exact difference between BE200 and BE202 is unclear, Intel confirms that BE200 has been pre-certified for Wi-Fi 7.

As far as known products are concerned, the upcoming gigabyte Aorus Z790 Master X motherboard (PCB revision 1.2) will use BE200, while some versions will use Qualcomm QCNCM865 (PCB revision 1.0) and MediaTek MT7927 and RZ738 (PCB revision 1.1).

Intel believes that Wi-Fi 7 is ideal for high-bandwidth activities, especially in augmented reality (AR) and virtual reality (VR) headsets using Intel's WiGig technology.

However, IEEE is not expected to confirm the final IEEE 802.11be specification until 2025, but companies such as Intel are optimistic about the potential of Wi-Fi 7. Obviously, this optimism is also reflected in these pre-release Wi-Fi 7 controllers and adapters.

From the Wi-Fi 7 scheme of many manufacturers exposed by "kuroberu", the mainstream manufacturer Z790 motherboard adopts the Wi-Fi 7 scheme of Qualcomm NCM865, MediaTek MT7927 / RZ738 and Intel BE200 / BE202.

Among them, MSI's new Z790 motherboard all adopts Qualcomm scheme, Asustek model adopts Intel scheme, and gigabyte Z790 series all have three solutions.

In terms of parameters, Qualcomm, MediaTek and Intel's Wi-Fi 7 program can reach a maximum speed of 5.8Gbps. Intel B202 wireless network card only supports the 160MHz band, the maximum speed is 2.4Gbps.

According to previous reports from CTOnews.com, the official website of the Ministry of Industry and Information Technology officially released a notice on June 1 to solicit the opinions of the State Radio Office on the approval of technical requirements and testing methods for new models of wireless LAN equipment using IEEE 802.11be technology standards. The relevant Wi-Fi 7 standards are expected to be launched soon, when a large wave of Wi-Fi 7 products will be put on the market.
