WI-FI ANTENNAS
• Two integrated dual-band moderately directional
antennas for 2x2 MIMO with maximum individual antenna
gain of 4.9dBi in 2.4GHz and 6.0dBi in 5GHz. Built-in
antennas are optimized for vertical orientation of the AP.
The horizontal beamwidth is roughly 120 degrees.
--Combining the patterns of each of the antennas of
the MIMO radios (in 2x2 mode), the peak gain of the
effective per-antenna pattern is 2.3dBi in 2.4GHz and
3.4dBi in 5GHz. | RF PERFORMANCE TABLE | | | Maximum transmit power (dBm)
