The signal coverage of the ZyXEL NWA1120 series is optimized with various 11n technologies, such as TX Beamforming and Maximum Likelihood Demodulation (MLD) for better, larger coverage. With MLD, the NWA1121-NI improves Signal-to-Noise Ratio (SNR) of about 3 dB that makes wireless services even more stable and better to support more mobile users. Meanwhile, TX Beamforming eliminates dead spots by expanding the coverage with continuous, dynamic change of signal phases.
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 functionality enables consistent wireless user management.
