smoothly without lag, significantly improving user experience. Crucially, Wi-Fi 7 has extended wireless coverage throughout the COE campus, providing staff with seamless, dead-zone-free connectivity anytime, anywhere.
Wi-Fi shield secures electric power campus network Wi-Fi has become the primary method for Internet access on computers and mobile devices, offering both convenience and reliability for office connectivity. Traditionally, Wi-Fi transmission security relies on symmetric and asymmetric cryptographic encryption at the MAC layer, such as the Advanced Encryption Standard( AES) algorithms used in WPA2 and WPA3 protocols.
However, because wireless signals propagate through the air, they are vulnerable to eavesdropping. Hackers can eavesdrop and store users’ data, which, under normal circumstances, would require a great deal of time to decrypt. However, in the era of explosive computing power( driven by AI), hackers can store and crack eavesdropped packet data quickly using large-scale computing platforms. As a result, traditional cryptographic systems may be compromised in the blink of an eye. This poses one of the most critical security risks of wireless communication when compared to wired networks.
But how can packet eavesdropping be prevented? Huawei has pioneered an innovative solution that addresses the issue at the physical layer of wireless
signal transmission and reception. This breakthrough forms a central part of Huawei’ s unique Wi-Fi Shield technology. By leveraging the firm’ s Wi-Fi Shield, clients can massively improve the security performance of wireless networks, effectively mitigating the risk of information leakage during transmission.
So, how does Wi-Fi Shield technology work? The AP precisely detects the physical location of the target user. When transmitting packet data, it simultaneously emits a randomised noise signal. This noise is algorithmically designed to cancel out( dropping to zero) at the target user’ s location, which allows only the target user to demodulate the packet data correctly.
