MediaTek says Wi-Fi 7 will replace Ethernet cables

Based on the IEEE 802.11be standard, the draft version of which was published last year, Wi-Fi 7 is expected to provide speeds several times faster than Wi-Fi 6 kit, offering connections of at least 30Gbps and possibly up to 40Gbps.

MediaTek boasts that this will make wireless connections a viable alternative to wired networks such as Ethernet even in applications that call for very high throughput, and predicts it will be used as the backbone of home, office and industrial networks.

Yeah!, right

Whilst it may offer high throughput, it still can't offer the low latency and high reliability that cable can

At least this might hopefully drive the uptake of 2.5Gbp/5Gbps/10Gbps/faster wired ethernet to actually provide wired backhaul to all of these new access points.

Yeah imagine that. A zero day wireless exploit comes out and your bank are running everything on WiFi 7.

Pretty sure I read an article like this years ago for Wi-Fi 6

And theoretically WiFi6 does do over 2Mbps. All this stuff is coming, and when it does we’ll buy it first. Like always!

Key Wi-Fi 7 Advancements

➤ Multi-Link Operation (MLO) that enables devices to both simultaneously transmit and receive across different bands (2.4GHz, 5GHz and 6GHz) and channels. Wi-Fi 6 could already harness several links simultaneously, but these links are usually independent, and MLO seeks to change that in order to make efficient use of the channel resources.

➤ Channel size of up to 320MHz (up from 160MHz with Wi-Fi 6)

➤ Support for 4096-QAM (Quadrature amplitude modulation) OFDMA (up from 1024-QAM)

➤ Support for 16×16 Multi-User, Multiple-input, Multiple-output (MU-MIMO) technology (up from 8xX UL/DL MU-MIMO).

NOTE: Wi-Fi 7 could also enable the use of additional spectrum bands between the 1Ghz and 7GHz+ range, but that may depend upon availability (regulation).

Whatever happened to Lifi? Wasn't that supposed to be faster than wired speed as well?
