Additional technical information

Dimensions: 553 × 398 × 190 mm (H × W × D)
Weight: 32 kg (preliminary figure in Ericsson 2018 Product Information)
Bandwidth: B8: IBW/operational 35 MHz; for GSM, 1.4/3 MHz LTE and NB-IoT standalone, IBW is 20 MHz per RF port. B28: IBW/operational 45 MHz; for NB-IoT standalone and 1.4/3 MHz LTE, IBW is 20 MHz per RF port
Capacity: Per band/radio: GSM 12 DL/24 UL; WCDMA 12 DL/24 UL; LTE 6 DL/6 UL; NB-IoT 4 DL/16 UL; total 12 DL/24 UL. Per band/port: GSM 4 DL/6 UL; WCDMA/LTE 6 DL/6 UL; NB-IoT 2 DL/4 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 IP65 Radio 4499 enclosure with convection cooling
Modules: TRX; 2 MCPA for each RF-port; filter unit with combining TX/RX and power splitting; protection SPD power DC, ALD, external alarms and RF; 2 optical module SFP+
Functional role: Outdoor dual-band macro radio unit with common RF ports for external antennas
Architecture: Self-contained dual-band radio sharing common RF ports between both bands; optical CPRI to baseband; external AISG TMA/RET
Subtype: Up to 4TX/4RX per band, common-port dual-band ERS Radio
Details: 26.5 l volume and 32 kg are preliminary; normal operation −40 to +55 °C; convection cooling
Installation conditions: Wall rail / pole bracket
Connection notes: Baseband; antenna; RET/ALD
