Features
Tweaks
Ender Modem Nerfing
In vanilla CC: Tweaked, Ender Modems are capable of transmitting and receiving messages from everywhere across all dimensions, with a virtually unlimited range.
This mod changes the behaviour of the peripheral by:
- Limiting the range to 2x normal wireless modem's range (unaffected by weather)
- Limiting the cross-dimensional messaging to work only if the block position is close by 8 blocks (scaling is applied, ie. 1:8 for overworld and nether)
Redstone Relay Enhancement
The network name of the Redstone Relay peripheral is now added to the redstone event.
Radio network
Radio Towers can be built to assist long-range wireless communication. Craft a Radio Tower Base, at least one Radio Tower Segment, and a Radio Tower Antenna and build the tower like in the image.

A smaller version can be used to receive data only: 
NFC
The NFC Reader peripheral is capable of reading and writing data to the NFC Card.
