A communication tower as they appear in Avatar: The Game
The communication tower is a standard structure used by the RDA to uplink encrypted information, operate GPS mapping, and synchronize data with orbital vehicles. They are also used to aid missile tracking.

In Avatar: The Game, Beyda'amo instructs Able Ryder to destroy four of the communication towers in the area around Iknimaya to stop the RDA's missile tracking from working. They are destroyed by placing explosive charges around the base of the towers. The attack on the towers was one of the contributing factors that lead to the Battle of Vayaha Village.
