addition, the router board injects noise from other components. The received signal deteriorates and noise is injected,
which reduces the efficacy of the received transmission.
Active antennas solve these problems. Active antennas move the powered amplification component (LNA) to the
antenna itself instead of using the router board. This eliminates signal loss during transmission since the active
antenna directly amplifies the received signal. In addition, since no noise from the router board components are
present in the antenna, the amplified signal is cleaner.
The router receives a much cleaner and less noisy signal for amplification, significantly improving the received signal
and providing a clean, powerful signal that extends WiFi coverage and performance. Active antennas help reduce
the mismatch between the sent and the received signal by compensating for the relatively poor WiFi on the client
side.This WiFi improvement is seen across all devices-new and old but helps mobile devices the most, which present
the greatest connectivity challenges today.
Position the Active Antennas
The router's four active antennas include a built-in receiver low noise amplifier (LNA), for high-speed WiFi connections
and excellent range. Both the 2.4 GHz and the 5 GHz low band (WiFi Channels 36–48 and 52–64) use the active
antennas. The 5 GHz high band (WiFi Channels 100–140 and 149–165) uses the passive antenna.
The best position for the active antennas depends on the layout for your home or office. We recommend the following
antenna positions:
•
For a large single-story home (about 2,500 to 4,000 square feet in size), position all four antennas vertically and
place the router on a table.
•
For a multilevel home, position the two antennas in the center vertically, and position the other antennas at a
45-degree outward angle.
