Additional technical information

Weight: 2020 Uen AM: 15.6 kg; 2018 Rev A: 16 kg
Dimensions: 2020 Uen AM: 420 × 342 × 131 mm (H × W × D); 2018 Rev A: 380 × 335 × 118 mm without protrusions, 420 × 342 × 123 mm with protrusions
Bandwidth: Up to 120 MHz IBW TDD
Capacity: Per branch: LTE 6 DL/6 UL carriers; NR 3 DL/3 UL carriers. Per radio: LTE 4 × 6 DL/UL; NR 4 × 3 DL/UL; mixed mode 4 × 6 DL/UL
Synchronization: When operated over its documented classic CPRI interface: CPRI slave synchronization; the radio recovers the incoming CPRI bit clock for radio/link transmission and receives time information from the REC/Baseband
Chassis: Standalone outdoor Radio 4418 enclosure with one-bolt/Ericsson Rail mounting support
Modules: 2 exchangeable SFP modules for optical CPRI
Functional role: Outdoor TDD macro radio unit for an external antenna
Architecture: Self-contained near-antenna radio with optical CPRI connection to baseband; star/cascade topology
Subtype: 4T4R single-band TDD macro ERS Radio
Details: 2018 Rev A: 15 l volume; normal operation −40 to +55 °C; cold start at −40 °C
Installation conditions: Rail / wall / pole
Connection notes: Baseband; antenna; AISG RET
