The Wireless Map is a special map added by ChickenBone's Mods with the ability to locate devices that are emitting a Wireless Redstone frequency. The emitters appear as red dots on the map, unless a Lumar has been assigned to the Frequency. The dot then shows up with the color of the Lumar. Be aware that lava also appears as red dots. A very good use for this is to activate a transmitter at a location and use that as a marker for things like your house.
The two red dots in the middle are pigs with Wireless Trackers on them. The other two dots over the volcano and sand are lava pits. In real time, the pigs' dots would be turning and moving with the pigs. The pigs' dots are discernible from the lava pools because they are not in line with the map.
