Wi-Fi 7 (802.11be), known as Extremely High Throughput (EHT) is the latest wireless networking standard with improved efficiency, lower latency, and higher transfer speeds up to 5 times faster than its predeccesor, Wi-Fi 6. The newest protocol operates across all three frequency bands 2.4GHz, 5 GHz, and 6GHz. Wi-Fi 7 uses advanced wireless techniques (MLO, OFDMA, MU-MIMO, and TWT) to enhance network performance and improve user experience.
The key features of Wi-Fi 7:
Multi-Link operation (MLO) is the central and most signficant feature of the new standard that enables devices to connect accross different ferquencies (2.4GHz, 5GHz, and 6GHz) simultaneously. By using multiple bands it can enhance reliability, reduce latency and increase data rates.
Higher data rates, theoreticaly up to 46Gbps due to improved higher modulation techniques and wider channel bandwidth.
Higher modulation that supports 4096-QAM (Quadrature Amplitude Modulation) allows more data to be tarnsfered and therefore increasing overall throughput.
Wider channel bandwidth with up to 320 MHz wide which allows more data to be transimtted at once and therefore enhances the troughput.
OFDMA and MU-MIMO allow efficient data transfer and sharing among multiple devices that improves network efficiency.
TWT (Target Wake Time) feature enhances the schedulle when devices wake up to transmit or receive data, which reduces power usage and improves battery life of devices.
Reduced latency make it ideal for use in real-time applications, extended reality (VR, AR, MR) and 4K/8K streaming.
WPA3 (Wi-Fi Protected Access 3) incorporates enhancements for secure and reliable network connections.
