The RRU3928 is an outdoor remote radio unit. It processes baseband and RF signal data. With the Software Defined Radio (SDR)technology, the RRU3928 supports the dual-mode operation of any two modes of GSM, UMTS, and LTE through software configuration modification. RRU3928 has a dual-transmitter and dual-receiver structure, which supports higher output power and carrier capacity.
It can f.ex. do 6x GSM carriers at each 10 Watt and 1x LTE carrier at 2×10 Watt or 4x GSM carrier at each 10 Watt and 2x UMTS carriers at 2×20 Watt.
