WI-FI ANTENNAS

Integrated downtilt omni-directional antennas for 4×4 MIMO in 2.4GHz with peak antenna gain of 4.3dBi, and 8×8 MIMO in 5GHz with peak antenna gain of 5.8dBi in 5GHz. In tri-radio mode, the peak gain of the antennas for each of the 4×4 5GHz radios is 5.5dBi (radio 0L, lower half of 5GHz) and 5.6dBi (radio 0U, upper half of 5GHz). Built-in antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 degrees.

A mix of horizontally and vertically polarized antenna elements is used

Combining the patterns of each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 2.4dBi in 2.4GHz and 0.7dBi in 5GHz (dual- radio mode).

In tri-radio mode, the peak gain of the combined, average pattern is 1.1dBi (radio 0L, lower half of 5GHz) and 3.6dBi (radio 0U, upper half of 5GHz)
