Redio Signals
Redio Signals is a Fabric technology mod that sends redstone-like signals through solid blocks and air as a new natural phenomenon called rediowaves.
What it does
Rediowaves are generated by signals and propagate upwards through the world. Encoder blocks convert a redstone signal into solid-type rediowaves that travel inside certain blocks, and Decoder blocks take solid-type rediowaves from nearby blocks and turn them back into up to three redstone signal levels. Copper blocks and other materials interact with rediowaves in different ways, and certain blocks can convert solid-type rediowaves into air-type and back again, which allows a chain of converters to carry a signal.
The mod is built as an experiment: the exact nature of rediowaves is still unknown, and the author describes it as early beta with most planned content not yet implemented. The exact list of blocks that carry solid-type rediowaves is unknown and is meant to be found by testing different blocks. A starter guide is available for players who want to begin studying rediowaves. Redio Signals requires Fabric API and runs on client and server, and the code is open source under the GNU General Public License v3.0 only. Files are published for Fabric and 1.21.4, with 0.5 as the latest file, dated 2025-09-13 and released on the beta channel.
Key features
Signal transmission through blocks
A simple setup with an Encoder and a Decoder sends a redstone signal across a gap without wires, as shown in the author's example picture.
Solid and air rediowaves
Rediowaves can take a solid form inside certain blocks or an air form, and converter blocks switch between the two.
Redioconductive blocks
Redioconductive blocks change how rediowaves behave, so each material can be tested for its effect.
Long-distance networks
The signal can carry information over long distances, which allows more complex mechanisms to be built.
Unfinished content
The list of blocks and the behavior of rediowaves are expanded and changed over time as the beta develops.

How it compares
TC Wireless Redstone is open source under the Apache License 2.0 and is published for Fabric, Forge and NeoForge across 1.12.2 – 26.3, while Redio Signals targets Fabric only for 1.21.4. Redstone Timer is open source under the MIT License and is published for Fabric 1.21.1 only, so it does not cover the 1.21.4 version that this mod uses.

Does Redio Signals need Fabric API?
Do the server and the players both need the mod?

What the author says
Redio Signals introduces a new natural phenomenon into the game — rediowaves. With their help, you can transmit information over long distances, build complex mechanisms, and do many other things we won’t reveal just yet. The exact nature of rediowaves is unknown. That’s why in this mod your task is to experiment…
