NAP203
802.11ac Dual-Radio, Dual-Optimized Antenna 3x3 Nebula Cloud
Managed Access Point
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.
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 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.
Real-time control of all the devices through
a single pane of glass
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.

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.

Robust Hardware
Fine art of RF design
Noises between RF circuits usually impact performance, and it’s
a critical EMI challenge too. The NAP203 isolates RF circuits by
solid shielding frames. Thus, electromagnetic interference (EMI)
is mitigated while RF performance is enhanced as well.
Solid capacitor for longevity
All-solid capacitor design provides
up to 6 times lifespan than
electrolytic capacitors that delivers
better stability and reliability.
