Features: 1. Adopt split-type detachable design. The network card and antenna can be removed and replaced separately. The expansion is strong and the external 2dB omnidirectional antenna can make the wireless signal transmission distance farther in the open environment. 2. External antenna, high gain 2dBi performance, receiving and transmission distance farther, bring you a different black hole experience, watching TV, listening to music, playing games, virtual time and space wireless forward. 3. The wireless CCA air channel detection technology can automatically adjust the bandwidth mode when avoiding wireless signal interference around, avoiding channel interference, and the wireless signal is more stable. 4. High-performance through-wall technology, strong penetrating power, in the complex wireless environment of blocking or multi-interference, can also provide better wireless penetration, signal is strong and stable. 5. 150Mbps transmission speed, the network card comes with an antenna, the signal is stable and strong. 6. Using flexible structure design, support multi-dimensional free rotation, users can adapt to the strength of the roots and signals, improve signal sensitivity, enjoy high rates.
