🛠️ Technical Deep Dive
- Wi-Fi 7 is formally known as IEEE 802.11be and is dubbed Extremely High Throughput (EHT).
- Key features include 320 MHz ultra-wide bandwidth, which doubles the 160 MHz limit of Wi-Fi 6, enabling significantly higher data transfer rates.
- It utilizes 4096-QAM (Quadrature Amplitude Modulation), allowing each symbol to carry 12 bits of data, a 20% increase over Wi-Fi 6's 1024-QAM.
- Multi-Link Operation (MLO) is a mandatory Wi-Fi 7 feature that enables devices to transmit and receive data simultaneously across multiple frequency bands (2.4 GHz, 5 GHz, and 6 GHz), improving throughput, reducing latency, and enhancing reliability.
- Other enhancements include Preamble Puncturing, Multiple Resource Unit (MRU), and 512 Compressed Block Ack, which aggregates up to 512 MPDUs in a single frame, reducing protocol overhead.
- The solution's five-layer soft handover technology is crucial for reducing handover latency to under 30ms, ensuring seamless connectivity at train speeds of 160 km/h.
- Wi-Fi 7 mandates support for WPA3 and Enhanced Open (OWE) with Protected Management Frame (PMF) for enhanced security.
