Every instillation is different. The differences depend on the “path loss” between the two units. Every obstacle in the line of sight means that the Coverage Unit and the Network Unit will have to be closer together. The cleaner the line of sight the further apart they can be placed. The more walls, doors, or refrigerators (obstacles), in the direct line of sight, the closer they units will have to be. The average distance for a typical construction home is 60 feet, however the placement can be as little as 20 feet or much as 120 feet apart.
