A Support system

B Digital Unit (DU)

Power Cabling in Single Support System Configuration with one DU

The RU main purpose is to send and receive signals. The RU receives digital data and converts it to analog signals. It also receives radio signals and converts these to digital signals.

TYPES OF RRU.• RUW(RADIO UNIT FOR WCDMA)• RUG(RADIO UNIT FOR GSM)• RUL(RADIO UNIT FOR LTE)• RUS(MULTISTANDARD RADIO)
