In its simplest this is a mod that allows you to transmit your redstone state wirelessly. Even if you dont use redstone this mod could still be for you. Found an awesome landscape you'd like to mark, a cool cave to explore, or keep losing your way from base to base? Ever wished that compass pointed somewhere else or there was a way to mark things on a map. Well now there is. With the wireless addons component of this mod you can use wireless signals for navigation.
The signals are synchronised in a dimension called the Redstone Ether or REther. This dimension has no physical form and purely stores signals. It can be accessed by combining the Interdimensional properties of Obsidian, Glowstone and EnderPearls from the OverWorld, Nether and Ender with redstone to enter the RedstoneEther. There are 5000 different frequencies storing independent state, name and colour. Due to the dimensional nature of the REther signals sent in the nether will translate into the OverWorld and vice versa.
