■ Supports 8 SSIDs
■ Supports IPv6
■ Coverage-enhancing 11n
functions including Low Density
Parity Check (LDPC), Maximum
Likelihood Demodulation (MLD)
and TX Beamforming
The ZyXEL NWA1121-NI is an IEEE 802.11n standard-based, SNMP-managed business WLAN
PoE Access Point (AP) with data rates of up to 300 Mbps.The embedded antennas of the
ceiling-mount AP enable large interior wireless deployments without sacrificing wireless
performance.
The signal coverage of the NWA1121-NI is optimized with 11n technologies such as TX
Beamforming and MLD (Maximum Likelihood Demodulation) for better, larger coverage. With
the comprehensive design and the support of IPv6, the NWA1121-NI is an ideal and optimized
solution for business, hospitality and education environments.
Benefits
Multifunction ceiling-mount design benefits large interior wireless
deployments
Different from traditional business wireless APs struggling to provide better coverage or
performance, the ZyXEL NWA1121-NI 802.11 b/g/n PoE AP has an“multifunction”design that solves
all problems. It embeds antennas without sacrificing wireless performance, while the ceiling-mount
design fulfills non-invasive deployment needs with factory-optimized coverage, especially for
hospitality and education areas.
Designed for plenum rating, the NWA1121-NI is made non-toxic material without hazardous vapor
emission.This safe design makes it more suitable for public indoor wireless deployments.
8 SSIDs for comprehensive user management
In different public environments, the administrators may use VLAN switches to separate the traffics
from different type of users; as such different group of users may need independent Wi-Fi security
settings too.The ZyXEL NWA1121-NI provides up to 8 SSIDs to map the VLAN security level settings
to classify users for different application services,such as public Internet access or restricted Web
contents.This function allows businesses to make consistent user management in wireless edge.
IPv6/IPv4 compatibility for future-proof expansions
Designed to solve the IPv4 exhaustion problems,the IPv6 architecture is being widely adopted in
worldwide deployments.With IPv6 features enabled,the ZyXEL NWA1121-NI ensures businesses with
a smooth migration path from the IPv4-based networks to the full IPv6 infrastructure.The
NWA1121-NI supports dual-stack that allows coexistence of both IPv4 and IPv6.With IPv6, the
NWA1121-NI can meet the networking trend and make all investments future-proof.

11n wireless technologies enhance coverage for up to 50%
Although 11n is the mainstay wireless standard today, it still has a few unsolved problems such as dead spots and inefficient coverage due to the output
power limited by regulations.The ZyXEL NWA1121-NI features coverage-enhancing 11n technologies such as TX Beamforming, LDPC and MLD to solve these
issues.With MLD, the NWA1121-NI improves Signal-to-Noise Ratio (SNR) for about 3 dB that make wireless services even more stable and better to satisfy more
mobile users.
Meanwhile,TX Beamforming also eliminates dead spots by expanding the coverage with continuous,dynamic change of signal phases.Better and larger
coverage reception will benefit low-power devices such as smartphones or tablets.With this enhancement, users can experience the best mobile wireless
service anytime, anywhere with the ZyXEL NWA1121-NI.
