Problemas con enlaces

[Nikless]

Hola buenas noches, mi nombre es nicolas. soy nuevo en el foro y la verdad no se como encarar este tema. soy tecnico en una empresa y estamos teniendo problemas de enlaces. quiero saber si me pueden ayudar. comento lo que tenemos en la empresa.
hay 3 ap. en una torre a 60 metros de altura aproximadamente, uno apuntando hacia el norte otro hacia el oeste y otro al sur, los ap son;
ap oeste; ePMP 3000
ap sur: ePMP 2000
ap norte: ePMP 2000
los suscriptores que se colocan en el pueblo serian force 180 y los force 200 son los que se ponen en la zona rural.
el problema son los force 200 el cual estoy teniendo que bajar del techo para colocarlos a 3 metros de altura para que se registren al AP con una señal promedio de 75/78. Los enlaces aproximadamente tiene 15,17km de distancia de suscriptor a ap
Mi consulta es si hay que configurar algo en el ap o que me esta pasando que estoy teniendo que bajar los suscriptores hacia el piso para poder registrarlo. No encontramos ninguna solucion mas que esa. espero poder haberme explicado y que me puedan ayudar. ya que mucho no entiendo porque soy un tecnico instalador pero me esta dando mucho dolor de cabeza este tema y no encuentro solucion.
saludos

Hello good evening, my name is Nicolas. I am new to the forum and I really don’t know how to approach this issue. I am a technician in a company and we are having problems with links. I want to know if you can help me. I will tell you what we have in the company.
There are 3 APs on a tower approximately 60 meters high, one pointing north, another west and another south, the APs are;
West AP; ePMP 3000
South AP: ePMP 2000
North AP: ePMP 2000
The subscribers that are placed in the town would be Force 180 and the Force 200 are those that are placed in the rural area.
The problem is the Force 200 which I am having to take down from the roof to place them at 3 meters high so that they register with the AP with an average signal of 75/78. The links are approximately 15.17km from subscriber to AP
My question is if there is something that needs to be configured in the AP or what is happening to me that I am having to take the subscribers down to the floor in order to register it. We have not found any solution other than that. I hope I have been able to explain myself and that you can help me. I don’t really understand because I am an installation technician but this issue is giving me a lot of headaches and I can’t find a solution.

@Nikless

with an average signal of 75/78. The links are approximately 15.17km from subscriber to AP

15KM is a LONG ways for a wireless subscriber link, with 132 dB of Free Space Loss, and with the low gain antennas you’re using on the AP & SM, there’s not much signal left. Signals near -80 are all you’re likely to get. Especially if you’re trying to do this at roof height - then the ground clutter and fresnel zone will also impact that signal negatively.

At that distance, I’d want to have the highest gain antennas I could… so on the SM side, you might want to test with an ePMP1000 connectorized or a Force 300csm paired with a 2’ (30 dBi dish) and see what difference that makes. If you don’t have those SMs on hand, you could even do a test with an 1000AP or 2000AP set in SM mode. And then pair the SM with something such as a RocketDish RD-5G30-LW

AND of course height often helps too, every 10’ (3m) is often around 3-5 dB if there’s distance and clutter in the fresnel zone path.
