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.
