Is the NanoStation loco M5 Wi-Fi antenna suitable for my internet scheme?

Question

Computer networks

Set up a scheme for the Internet via wi-fi. The diagram shows 4 access points - you can connect to any of them via the NanoStation loco M2 wi-fi antenna , which then transmits the signal via a regular Internet cable to a router that distributes the Internet. This scheme worked for several months until the antenna broke. Now I want to buy a new one, but when I went to the store on the shelf, I noticed another antenna - loco M5 , which is twice as powerful as the previous one, which means it should catch the signal better. The seller is new, he tried to explain to me that it would not work for my scheme - this stopped me, or maybe I misunderstood him.
Friends advised to ask a question on Toaster. So I want to buy this antenna - loco M5, so that it catches the signal more powerfully. Do you think this loco M5 model will fit my circuit? Or, as this seller said, is it for other purposes? I searched for information on the net myself - I was completely confused.
I spread for comparison the characteristics of both models:
LOCO M2:
2.4 GHz | 150 Mbps | 8 dBi | Up to 5+ km Range
LOCO M5:
5 GHz | 150 Mbps | 13 dBi | Up to 10+ km Range

Answer 1

If there is someone to connect to at a frequency of 5 GHz, then why not. Just keep in mind that the use of the 5 GHz band is subject to licensing, first ask for a license from those offering such an Internet.
