How much land is needed for a cell tower?

I'm curious to know, how much land is typically required for the construction and operation of a cell tower? Does the amount of land needed vary depending on the size or type of tower? Are there any regulations or guidelines that dictate the minimum or maximum amount of land that can be used for a cell tower? And finally, how does the amount of land needed for a cell tower compare to other types of telecommunication infrastructure, such as fiber optic cables or microwave relays?
