<b>802.11 b/g/n PoE Access Point</b>
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.
<b>Multifunction ceiling-mount design benefits large interior wireless deployments</b>
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 a “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.
<b>8 SSIDs for comprehensive user management</b>
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.
<b>IPv6/IPv4 compatibility for future-proof expansions</b>
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.
<b>11n wireless technologies enhance coverage for up to 50%</b>
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 3dB 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.
