Wi-Fi 7, also known as Extremely High Throughput (EHT), is the newest Wi-Fi wireless standard that aims to provide extraordinary speeds while operating on the 2.4GHz, 5GHz, and 6GHz radio. Wi-Fi 6E is the next iteration of Wi-Fi 6 (802.11ax) with the same features and the addition of a new 6 GHz wireless band.
The following are the key features of the original Wi-Fi 6 (802.11ax):
-
Orthogonal frequency-division multiple access (OFDMA) – Allows the router and connected devices to efficiently use the bandwidth by reducing the time interval between data transmissions. This reduces the bandwidth used which can be allocated to other devices.
-
Eight-stream multi-user-multiple-input multiple-output (MU-MIMO) – Allows the router to connect to multiple devices at the same time. Wi-Fi 6 enables 8x8 access points to transmit information via all eight streams.
-
Higher-order modulation (1024-QAM) – Improves data transmission speed and efficiency on the network. Transfer speed is increased by up to 25%.
-
Target wake time (TWT) – Extends the battery of your mobile devices and smart home devices by reducing the communication time between the router and connected devices. Devices that have TWT will enter sleep mode until the scheduled communication time. This reduces the power consumption and bandwidth use of all connected devices that support TWT.
The addition of the 6 GHz wireless band provides new features and improvements on the Wi-Fi 6E:
-
New 6 GHz spectrum – Supports up to 14 80 MHz channels or 160 MHz channels. With additional Wi-Fi channels, this reduces the overlap between networks that create interference.
-
More high-bandwidth channels – Almost double the supported high-bandwidth (80 GHz, 160 MHz) channels as 5 GHz. High-bandwidth channels are necessary for high-resolution streaming, VR gaming, and HD video conference.
-
No DFS scanning required – 160 MHz channels in the 6 GHz wireless band do not share the spectrum with radar devices or TV stations. This has an issue for the 160 MHz channels in the 5 GHz wireless band, especially for areas near airports and TV stations.
-
Wi-Fi 6E devices exclusivity – 6 GHz wireless band is restricted to devices that support Wi-Fi 6E. This allows Wi-Fi 6E devices to fully utilize the 6 GHz features with no interference from non-6E devices.
-
Mandatory Wi-Fi Protected Access (WPA) 3 – All Wi-Fi 6 devices that are using 6 GHz will have WPA 3. This offers the latest security and authentication protocols. 6 GHz Wi-Fi Networks provide better security and make it harder to hack.
The following are the main highlights of the new Wi-Fi 7:
-
Extraordinary speed – The expected maximum speed of Wi-Fi 7 is 46 Gbps for one user.
-
Increased channel width – The additional spectrum in the 6 Hz band allows the channel bandwidth to increase to 320 MHz wide. This increase allows more data to be accommodated and moved without a hitch.
-
Increased Quadrature amplitude modulation (QAM) - QAM is the encoding of data on a radio signal. From a QAM of 1024 for Wi-Fi 6, it is now expected to be at 4096 for Wi-Fi 7.
