The BTS3900 supports –48 V DC power input and the modules. The modules of the BBU3900 and CRFU are installed in a centralized way in an indoor cabinet. As the most compact indoor macro BTS in the industry, the BTS3900 features a large capacity, good extensibility, light weight, and a small size. In addition, the BTS3900 can be stacked and combined to save space Item Specification Working band Frequency band Receiving band Transmitting band Band class 0 (800 MHz) 824 MHz to 849 MHz 869 MHz to 894 MHz Band class 15 (AWS) 1710 MHz to 1755 MHz 2110 MHz to 2155 MHz Band class 1 (1900 MHz) 1850 MHz to 1910 MHz 1930 MHz to 1990 MHz Band class 14 (US PCS 1.9 GHz) 1850 MHz to 1915 MHz 1930 MHz to 1995 MHz Band class 6 (2 GHz) 1920 MHz to 1980 MHz 2110 MHz to 2170 MHz Max. number of carriers supported by one CRFU 8 Transmitter and receiver specifications Frequency band Receiver sensitivity Max. transmit power Band class 0 (800 MHz) –130 dBm 100 W Band class 15 (AWS) –127 dBm 80 W Band class 1 (1900 MHz) –127 dBm 80 W Band class 14 (US PCS 1.9 GHz) –127 dBm 80 W Band class 6 (2 GHz) –127 dBm 80 W Transmission ports Max. configuration Number of available ports One CMPT (4E1) and two UTRPs One FE electrical port and one FE optical port (supporting a maximum of 20 E1/T1 links) One CMPT (8E1) and two UTRPs One FE electrical port (supporting a maximum of 24 E1/T1 links) NOTE The CMPT (8E1) does not support the ATM transmission.
