The CloudRAN IRU was designed by Eurecom. Today, TELMAT Industrie is the only provider able to supply it to customers.

General description of the IRU

A CloudRAN RRU, or IRU, consists of the following main components :

1. Pico-ITX or smaller motherboard (UP-board, UP2)
2. Baseband-to-RF radio units (USRP B200-mini)
3. EURECOM-designed RF front-end circuit (25-27 dBm at the antenna port).
4. Wiring for 1Gbit/s Ethernet with Power-over-Ethernet modules (PoE) to provide power to the radio units.
      An additional 10 MHz frequency synchronization cable is also distributed to each RRU.

These modules can be used as:

• IF4p5 RRU (with UP or UP2)
• NFAPI PNF (with UP2)
• 5-10 MHz eNodeB (with UP2)

They are powered via PoE+ and require less than 20W. They can also be synchronized using methods that are part of the current OAI codebase.
