Wireless networking is easier to do in practice than it is to learn in theory. You will understand more by jumping in right ahead rather than poring through the books. But if you’re an absolute beginner you need to start somewhere. Here's an overview.https://t.co/X5p6fP60yA
The biggest problem being faced by the telecom industry is commoditization of their core service. The way things stand people can’t really tell the difference between the operators. The only thing that makes them choose one over the other is the price.

If you are a small ISP or WISP looking for cheap ways to reach more customers build your own wireless base station. Install openwrt and you're ready to go.
Gigabit speeds without having to deal with installation of fiber optic networks is a big win. It slashes your infrastructural investment by 1/10,maybe more. Giving you faster returns
You may ask, is this how the base station for 5G and 4G is created?
Yes but they use different wireless chips and the software to control these chips are proprietary.. for now. But inside the components are the same. A motherboard, RAM, processor, peripheral components.
