They absolutely didn't. This is well established. What they did have is signal towers. There are towers throughout the 4 corners regions that enabled communication from (for example) SE Utah (Bears Ears) over to CO (mesa Verde), down to AZ or over to NM (Chaco, Salmon, et al). It is of course unknown the extent and nature of the communications. Not all communication were via the towers; sites have been found that are in visible sight lines with towers but are just bare hill tops, bare except the extensive fire damage created by undoubtedly decades of fires lit there.
