Communication tower and broadcasting

I suddenly noticed the abandoned communication station used for obtaining opening resources at the beginning. Although it had to be deconstructed in order for the game to start normally, does this mean that this island used to have the ability to communicate externally? Because in the game, although the residents have all kinds of modern living materials, it seems that there is no other external communication channel except for the workers working outside and the cargo ships going back and forth. Even with the Internet, they can only connect to the information on the island, so the residents will not feel bored every day?
So I thought, could we add a "communication tower" building that consumes a lot of electricity to send broadcasts and generate unity.At the same time, it can be set to view the remaining resources of mines on the world map and issue alerts when resources are insufficient. Building multiple ones will have benefits but will quickly have marginal effects, so we won't build too many.
