FAQ


Q1: What platform is FRMF 472930A on? Can it replace ARMA 474803A directly?

A1: FRMF 472930A = Flexi Multiradio platform. ARMA 474803A = AirScale platform. They are both Band20 6T6R 360W, but BBUs and software stacks are completely different. Cannot hot swap / direct replacement. FRMF works with Flexi FSM; ARMA works with AirScale ASIB/ASIC BBU.

Q2: Does FRMF 472930A support 5G NR? 

A2: No. This Flexi FRMF hardware & firmware only supports FDD-LTE 4G. It has no 5G NR capability. If you need B20 5G FDD, select AirScale ARMA series instead.

Q3: Is this unit fanless? What is the maintenance advantage? 

A3: Yes, fully passive cooling with no fan. No rotating parts, low failure rate, less on-site maintenance, perfect for remote rural sites where service access is difficult.

Q4: Can FRMF 472930A work with non-Nokia BBU or other vendor baseband? 

A4: Not supported commercially. CPRI interface is Nokia Flexi proprietary for FSM module. Interoperability with third-party baseband is not validated and not recommended.

Q5: What is the typical deployment for FRMF 472930A?

A5: It is mainly used for wide-area low-band coverage, rural coverage, LTE refarming, coverage fill-in. Common deployment: three-sector site, each sector runs 2T2R MIMO, consuming 2 TX/RX paths out of the 6 available pipes.
