    Thanks !!! now there is a question of upgrading the computer. An error came out that there is not enough RAM (8 GB installed). If anyone has experience, tell me what configuration - processor and video card to buy so that it works well. Not Nvidia Tesla :))). I tried it on a friend's laptop with windows . It turned out to run CUDA . Thank you.

    maybe there is some kind of CUDA performance program?

    we are using WiFi 5 and for the client that will connect is relative because I want as much as possible
    Thank you

     

    how would I do:
    - plan of the area (park, stadium, sports ground, monuments)
    - according to the plan, where it is allowed to install access points (permission from the city administration or building owners, installation on lighting poles or making new supports for access points)
    - weather conditions (climate, sun, humidity. Installation outdoors or indoors) Even protection from birds (bird shit). This seems funny, but I had to make protection from crows on the GPS antenna. The bird loved to sit on the antenna and the signal was of poor quality. I taped toothpicks onto duct tape to stab the crow's ass.
    - Based on such data, you will already have a plan for where you can install access points and where you can’t.
    - decide how many people you plan to simultaneously connect to access points. Will there be a limit on access speed? And they will. Or which billing to deploy. Otherwise, your entire network will be destroyed by those who like to use torrents for free.
    - If this is a stadium, then there are definitely corporate-class access points. A simple SOHO access point will not be able to serve more than 10 people.
    - Do you need seamless roaming between access points (for example, a park, a client walking or riding a bike)
    This will give you the hardware requirements. From the site plan you will understand where access points can be placed and where not. And approximately the coverage of the WIFI network.
    - and here we need antennas or not.
    May be better to place access points in a star topology

    P.S By the way, the issue of electricity supply is also important - laying electrical power cables will be prohibited and something will have to be invented

    Hello,

    I'm working on a project to extend our community WiFi and could use some expert advice. Here's what I'm trying to accomplish:

    1. Broadcast existing community WiFi signal to a location 5km away
    2. Create a hotspot at that remote location with a 1km radius

    My questions:

    1. What equipment would you recommend for the long-range WiFi transmission (5km)?
    2. Any suggestions for creating a robust hotspot with a 1km radius at the remote location?
    3. What are the main technical challenges I should be aware of?

    I'm relatively new to large-scale WiFi projects, so any advice, resources, or cautionary tales would be greatly appreciated. Thanks in advance for your help!

    First you need to decide what channel speed you need. How many clients do you plan to serve at the same time? And then think about antennas.

    ,,, at the request of the user "Curb S. Gutter", I tried to optimize this antenna for a wider frequency band...

    Where can I find such a dialectical polystyrene? Is it suitable in a building materials store? I'm sorry for the stupid question, as I understand it, you need a material with certain characteristics of dialectical permeability?

    changed the connection location and replaced the wire with strips in the connection. 

    If you have free time, can you check me out? I'm still in CST. According to your articles on the forum. A little later I will put optimization

    I apologize for the arrogance:) do not share the project file? In order not to waste your time, I will play with the size of the antennas myself.

    ,,,my friend, for which frequency do you want the antenna to work...???

    I fly this antenna now at 1320 MHz. I suggest you stay that way. Cut less:))))

    Aksonx2,

    ,,,I finally managed to do the simulation for you, but it seems that the antenna is not quite successful..!!!

    Thank you so much for your time. It also seemed to me that this antenna connection option is a little incorrect. 

    I changed the location of the cable connection in the middle of the connection line, above I posted a photo. The results were as follows on the analyzer. The results above are incorrect since they were in a small room and industrial interference was detected on the air

    Aksonx2, please excuse me, I have small problems with the simulation program and I'm going to be a little late with it...!!!

    Don't worry. It's ok. I'm also waiting for windless weather to test this antenna option in field flights. Science requires sacrifice!!!

    ,,,вы забыли диаметр заплаток и провода...!!!

    sorry!!! diameter of the patch 125 mm, diameter of the wire 1.5mm

    Please tell me if there is a calculator or model. I bought for video such an antenna at a frequency of 1320 MHz. Is the structure assembled correctly? During transportation, I bent the matching line a little, what distance should be from the reflector? An image of such an antenna slipped on the forum but lost:)))
