This mission is similar to one of the previously played and it assumes that you disable enigma's communications tower, in order to deactivate the jamming signal. The new tower that you are looking for is in the North-Western part of The Bowery district. Since there is a group of enemies here, I recommend that you bounce off a ledge above and attack them from above. Eliminate all of the bandits deployed around the tower.
The tower itself is enclosed within an electric fence. Stand somewhere near and select the Remote Control Batarang from the inventory. Throw the batarang and make sure that it flies through the hole shown in the above screenshot. The batarang should charge as a result of coming into contact with the electric field and, to complete the process, you need to steer it into the fuse box.
You can now open the gate and the large door. From the inventory, select the Cryptographic Sequencer, start hacking into the terminal and determine the appropriate password (the screenshot).

[Enigma's Relay Network Unlocked: The Bowery]
Exit the tower and wait for Batman to start the process of tracing Penguin again, using the Cryptographic Sequencer so this mini-game is not too difficult. Use the analog stick, or appropriate keys to place the crosshair inside the orange circle. Then, press and hold down the key/button for deciphering the transmission and listen to another conversation with Alfred.
