802.11ac Dual-Radio Smart Antenna 3x3 Nebula Cloud Managed Access Point

The Zyxel Nebula NAP303 802.11ac Dual-Radio Smart Antenna 3x3 Nebula Cloud Managed Access Point is a high-performance 3x3 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.

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.

Benefits 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 auto-configuration, 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.

Best-in-class coverage and performance

Different from other 802.11ac APs, the Zyxel NAP303 stands out with its best-in-class coverage and performance thanks to its unique RF design. The AP's three-stream hardware configuration provides power of up to 30 dBm and unparalleled receive sensitivity of as low as -102 dBm. The Smart Antenna technology doubles the NAP303's performance over conventional internal antennas, and it performs three times (3x) better than legacy 802.11n APs as well.

Optimized wireless experience

The Zyxel Nebula NAP303 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.
