The Zyxel Nebula NAP203 802.11ac Dual-Radio, Dual-optimized Antenna 3×3 Nebula Cloud Managed Access Point is a high-performance 3-stream 802.11ac Wi-Fi AP featuring ultra-fast speeds of up to 1.75 Gbps with a groundbreaking “dual-optimized” antenna design. Through the innovative adjustable antenna setting, the NAP203 can provide the best signal coverage in both ceiling-mount and wall-mount deployments to deliver constant, no-compromise Wi-Fi performance. Additionally, the ultra-slim ID design at 32mm height blends perfectly into modern interior decorations.

Zero-touch deployments

The Zyxel Nebula NAP102 auto-configures itself after installation and then automatically connects to the Nebula cloud to join the network; so autoconfiguration, provision, monitoring and diagnostics can be performed anytime, anywhere. This simplifies network setup and enables deployment of Nebula APs to a remotely located network even by non-IT professionals.

Dual-optimised antenna design

Ceiling-mount installation is now the major type of wireless deployments; it is still common that most APs on the market today are designed with a single static radiation pattern for ceiling-mount installations. However, this kind of design may create interference with devices on upper and lower floors, and it delivers only short-range signals to wireless clients placed in front of the wall-mount AP. To deliver optimal Wi-Fi performance in both ceiling- and wall-mount installations, the Zyxel NAP203 features an innovative “Dual-optimized” antenna. Pattern of the antenna can be adjusted via a physical switch or cloud configuration in just seconds.

Enterprise-class security

The Zyxel Nebula NAP203 inherits the NETCONF protocol for secure configuration changes. In terms of authentication and data encryption, it supports WPA2 enterprise protection and a wide range of Extensible Authentication Protocol (EAP) types, including EAP SIM for smartphones. Besides, the NAP203 also features access control and Layer-2 isolation for privacy protection. The comprehensive security features ensure NAP203 to deliver enterprise-grade protection to the entire network.
