Hi there
welcome to PF :smile:

Why do Wi-Fi waves have such short distance and some microwaves are used for sending information through long distances?

the difference in transmitted power levels .... simple as that

Also point to point microwave links will be line of sight (LOS) .... this provides the least attenuation possible

Point to point microwave links don't have to work through walls, have higher power, use much better (more directive) antennas, and might have better receivers. The communication networks also may have other redundant links to deal with drop-outs (thunderstorms etc.). Other than that they are pretty much the same thing.
