Efficient Wi-Fi (Beamforming Technology)

Rosewill RNX-AC1900PCE supports the latest Beamforming Technology which intelligently strengthens wireless connectivity with precise directional signal amplification for extended coverage, increased data-throughput speed, and enhanced stability. Unlike the previous generation of Wi-Fi, Rosewill RNX-AC1900PCE intelligently identifies the locations of wireless routers and directly connects with data transmissions using three external antennas and high-gained beam-packing connection to give the best internet experience to users.


Wider Range with High Gain Detachable Antennas

Three High Gain detachable dual band antennas create optimally tuned and wider wireless coverage. With three upgradable dual band antennas, Rosewill RNX-AC1900PCE can provide the perfect placement for ultimate reception and the highest quality Wi-Fi networking which means you are able to get your Wi-Fi signal with longer coverage and enjoy your high speed internet ubiquitously. (Depends on your wireless router speed and coverage)


Stylish Aluminum Heat Sink

The advanced and stylish heat sink uses high-density aluminum to dissipate heat from the chipset, ensuring the reliability for long time operation. Lower temperatures turn into a more stable connection in all climate conditions, even under the extreme hot temperature, and well-designed ventilation helps to avoid overheating problems and to maintain perfect performance at its highest level.
