Thanks for the suggestion. I had already thought about this problem but I will not use the most power, I thought about setting 500mW with 2 antennas 120 degrees 14dBi in 2.4GHz connected to a hyperlink splitter. There are 40 users with 15dBi antenna. My main doubt is whether this brand Alfa Radio Networks is reliable? Thank you very much for your comments.
I think that using a splitter it’s not reliable…
