Hi,
Both APs are design with built-in antennas that are optimized for horizontal ceiling mounting orientation. I would suggest you consider mounting the AP horizontally or go with AP114 with external omni directional antenna.
- AP110 series is 3x3:3 which means you can get up to 450Mbps.
- AP 105 is 2x2:2 which means you can get up to 300Mbps.
If you ask me I would go with AP110 series.
Thank you.
