Wireless networking technology enabling devices to connect to networks without physical cables.
Wi-Fi is wireless networking technology using radio waves to connect devices to networks. Wi-Fi enables mobility and convenience but introduces security considerations—wireless signals extend beyond physical boundaries, encryption is essential, and rogue access points can capture traffic. Modern Wi-Fi uses WPA3 encryption (or WPA2 at minimum). Enterprise Wi-Fi often uses 802.1X authentication with RADIUS servers for stronger access control.
Why It Matters
The DSC Perspective:
Wi-Fi extends your network into the air, accessible to anyone nearby. Use strong encryption (WPA3/WPA2), separate guest networks from corporate, and monitor for rogue access points.
