For PN KRC161787/1. - Downlink frequency
- PN KRC161787/1; B1: 2110–2170 MHz; B3: 1805–1880 MHz
For PN KRC161787/1. - Bandwidth
- B1: IBW/operational 60 MHz (NB-IoT standalone within 20 MHz per RF port); B3: IBW/operational 75 MHz (GSM and NB-IoT standalone within 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
