I have tried asking around but I can't seem to find the answer that fits my situation.
I am in a rural area and the network here is terrible.
I want to extend the existing telecommunication companys' signal and customize its use in the extended area.
Like creating a LAN where you can customize the functions in your LAN before the user data gets through your Internet Access Point to the ISP.
To clarify, let me give an Example Scenario: Let's say a villager wants to use my extended network. The network should be able to verify if the user has registered to use the extended network service and give them access to the extended service's USSD apps, internet access(through the existing ISP) and more.
If u have a hint or the actual answer, please point me in the right direction. Thank you.
