What's the purpose of this structure?

Canada went through a era where they were increasing tremendously on building structures, most of them were skyscrapers, large office buildings, etc. But, soon they reached a problem where their skyscrapers were blocking the television and radio frequency signals, so to resolve their problem by building a communications tower tall enough so that any radio or TV communications from it would not be obstructed by other high-rise buildings in the city. The tower also served as a hub (central point) for microwave transmissions, allowing two businesses that were not visible to each other to exchange data by having the tower transmit it.
