The Shimano EW-WU111 is an inline wireless unit (D-Fly) for 11-speed Di2 systems. It connects in-line between two E-Tube wires using its two E-Tube ports, adding ANT+ and Bluetooth LE wireless communication so the Di2 system can pair with a head unit (cycling computer) or the E-TUBE smartphone app for gear display, settings changes and firmware updates.
