Item Description:
3x3 11AC Cloud Managed AP (1 Year Bundled Service)

The Zyxel Nebula NAP203 802.11ac Dual-Radio; Dual-optimized Antenna 3x3 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.

Every Nebula AP has been engineered for cloud management. Based on the NETCONF standard; all data traffics between the cloud and APs are exchanged using secure transports to ensure transaction-safe configuration on all Nebula devices. Furthermore; with the intuitive management interface; administrators are able to control all the APs quickly even without training.

Zero-Touch Deployments

The Zyxel Nebula APs auto-configure themselves after installation; and then automatically connect 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-Optimized 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.

Optimized wireless experience

The Zyxel Nebula NAP203 delivers optimized wireless experience for users with comprehensive wireless features such as Dynamic Channel Selection (DCS); Load Balancing; and Smart Client Steering; etc. DCS avoids interference from co-channeling and overlapping channels continuously; while Load Balancing and Smart Client Steering which features Band Select and Balance for more spectrum to provide more stable; reliable wireless connections.

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

Ultra-slim exterior design

Zyxel Nebula NAP203's ultra-slim exterior (32 mm in height) and understated white color blend perfectly into all kinds of decorations in various buildings with extraordinary modern tastes. The compact; elegant aesthetics makes NAP203 suitable for different decors no matter it's meant to be visible or not.

Dual-Optimized Antenna

The unprecedented Dual-optimized Antenna is an adjustable internal antenna with "just fit" pattern options optimized for wall- or ceiling-mount that the installation technician can instantly change the antenna pattern simply via the physical antenna switch without booting the device. If needed; administrators can base on their know-how to perform granular signal optimization per floor plan via software configuration remotely. With the flexibility; the NAP203 can fit for wallmount or ceiling-mount deployment without the hassles of antenna accessory selection and signal coverage adjustment.
