You need to connect two buildings across a public road and it is not feasible to use a direct cable connection. Under what circumstances would you use a microwave link what about the other wireless al?

A microwave link would be used to connect two buildings across a public road when a direct cable connection is impractical due to obstacles, cost, or regulatory issues. This method is effective for high-bandwidth applications over medium to long distances, especially when line-of-sight is achievable. Other wireless alternatives, such as Wi-Fi or radio frequency links, may be suitable for shorter distances or lower bandwidth needs, but they often have limitations in terms of range, interference, and capacity compared to microwave links.
