AT&T’s Home Gateway (HGX-3000 series) includes Wi-Fi 6E (6 GHz) and Thread/Zigbee for low-power IoT devices. The network dynamically allocates bandwidth via AI-driven traffic shaping, preventing congestion when 100+ devices (e.g., smart locks, security cameras, thermostats) are active simultaneously.
-
Mesh Network Compatibility:
Unlike cable modems, which rely on coaxial backhaul, AT&T Fiber’s PON architecture supports distributed mesh topologies. This enables seamless roaming for devices like Amazon Echo, Google Nest, and Philips Hue, reducing latency in large homes (e.g., 5,000+ sq. ft. estates).
