Additional technical information

Dimensions: 400 × 220 × 140 mm without housing; 400 × 240 × 160 mm with housing
Weight: <=13.5 kg without housing; <=15 kg with housing
Bandwidth: PN 02319445 frequency-variant IBW: 15 MHz; PN 02319446 frequency-variant IBW: 20 MHz. LTE FDD carrier bandwidths documented for the model: 5/10/15/20 MHz, subject to the variant IBW; dual-carrier configuration uses 10 + 10 MHz
For PN 02319445 frequency-variant IBW: 15 MHz.
Capacity: LTE FDD: 1 carrier (5/10/15/20 MHz) or 2 carriers (10 MHz each), within the frequency variant's IBW; LTE NB-IoT: 1 carrier
Synchronization: In mode CPRI: clock signal recovery from the incoming line; frame synchronization from REC
Chassis: Self-contained remote-radio enclosure, documented in versions with and without the external housing
Modules: High-speed interface unit, signal-processing unit, power amplifier, duplexer, extension-port section and power module
Architecture: Software-defined 2T2R remote radio unit connected to the BBU over CPRI; internal RF/IF conversion, signal processing, power amplification, duplexing and power sections
Details: Exchanges downlink/uplink baseband data with the BBU; performs RF-to-IF and IF-to-RF conversion, amplification, A/D and D/A conversion, and RX/TX multiplexing and filtering
