The Zyxel Nebula NAP303 802.11ac Dual-Radio Smart Antenna 3×3 Nebula Cloud Managed Access Point is a high-performance 3×3 802.11ac Wi-Fi AP capable of delivering combined data rates of up to 1.75 Gbps. Featuring Smart Antenna technology, the NAP303 perfectly solves coverage problems by adjusting antenna patterns adaptively to fit different wireless environments. The NAP303’s industry-leading RF output power and sensitivity jointly offer greater coverage and better performance to networks. The ultra-fast capabilities makes NAP303 perfect for interference-laden environments, such as conference rooms, airports, educational facilities and other high-density venues.

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.

Smart antenna technology

Featuring more than 700 optimized antenna patterns, the Smart Antenna can continuously calculate the ideal physical-layer path for each individual client. This feature not only offers the best possible signals by shaping to various patterns, but also mitigates interference from other wireless clients. With the advance technology, the Zyxel NAP303 can handle a variety of tough deployments such as high-capacity, high-performance and interference-laden environments

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.
