we have a big factory with 60000m^2 (200m*300m). they want a wifi networking for internet and calling together in their network for indoor and outdoor space. they have 11 big saloons. they have 300 workers. what do you suggest for indoor and outdoor (routerboard)? i think that i should use 3 base box2 with three 120 degree sector antenna for outdoor, do you think it’s siutable or not? what do you suggest for indoor?

this is the area
this is the area
Can you send me google maps link of your location?
the location is not important, the choice of the radio to cover the whole area is important. i get confused with so many radios. what is the best choice?
I recommend you, using basebox2 with 6dBi omni antennas.
so with this 6dB omni antenna ishould use many of them. how about using 15db antenna instead if it?
15 dBi antennas need more power and you must replace original power adapters with 24 volt 3 amp adapter
and if your want use your wifi network for servicing smartphones there is no different between 6dBi and 15dBi
do you think i should use two 6dB antenna with SMA Connectors in outdoor area or i should use two 6dB N-Male antenna and connect it with cable to base box 2 ? is it better than 15db? i think 15dB antenna have another broblem, it’s good in horizontal but bad in vertical, i need good signal in horizontal and vertical. how about 9dB omni antenna? it’s between 6 and 15. what about metal 2 with 6dB or 9dB antenna? which one is better?
base box2 or metal 2? are they can handle the voip?
can i use two 6dB omni antenna with SMA connector directly to basebox2 (without cable hood) in outdoor? Is rain or moisture damage the basebox 2?
Can you explain your logic a little bit? Antennas are passive devices. 
in my experience, 15dB antennas are good in horizontal but bad in vertical ( you have weak signal below of them ) and you should put them near ground (with 1.5m to 2m height) but 6 to 9 dB antennas are good in horizontal and vertical and you can put them in more height.
