| Wi-Fi Antennas | Integrated downtilt omni-directional antennas for 4 x 4 Multiple-Input, Multiple-Output (MIMO) in 2.4 GHz with peak antenna gain of 4.3 dBi, and 8x8 MIMO in 5 GHz with peak antenna gain of 5.8 dBi in 5 GHz. In Tri-Radio mode, the peak gain of the antennas for each of the 4 x 4 5 GHz radios is 5.5 dBi (Radio 0L, lower half of 5 GHz) and 5.6 dBi (Radio 0U, upper half of 5 GHz). Built-in antennas are optimized for horizontal ceiling mounted orientation of the Access Point. The down tilt 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 2.4 dBi in 2.4 GHz and 0.7 dBi in 5 GHz (Dual-Radio mode). In Tri-Radio mode, the peak gain of the combined, average pattern is 1.1 dBi (Radio 0L, lower half of 5 GHz) and 3.6 dBi (Radio 0U, upper half of 5 GHz) |
