FAQ
Q1: What network standard and frequency band does Nokia AHHB 474252A support?
A1: It is FDD LTE Band7 (2600MHz) RRH, working for 4G LTE networks. TX:2620–2690MHz, RX:2500–2570MHz. It cannot be used for TDD LTE or other frequency bands without hardware variant.
Q2: What is the MIMO configuration and RF power of AHHB 474252A?
A2: 4T4R MIMO configuration, total RF power 160W (4×40W per channel). 4T4R improves spatial multiplexing, coverage and LTE throughput compared with 2T2R radios.
Q3: What is the connection between AHHB 474252A and BBU?
A3: It connects to Nokia AirScale BBU via CPRI optical fiber (OPT1/OPT2 ports). CPRI carries IQ data, control and synchronization signals between baseband and remote radio.
Q4: Can this unit be installed indoors?
A4: It is designed as outdoor IP65 radio. Indoor installation is technically possible but not recommended; it is optimized for tower/pole outdoor deployment with passive heat dissipation.
Q5: What power supply does AHHB 474252A require?
A5: 48V DC telecom power supply. It is the standard power input for Nokia AirScale RRH series, must use qualified telecom DC power system.
