The pRRU5928 processes RF signals. It provides the following functions:
|Frequency Bands||850 MHz + PCS + AWS + 2,600 MHz
|Frequency Range||850 MHz: UL: 824 to 849 DL: 869 to 894
PCS: UL: 1,850 MHz to 1,910 MHz DL: 1,930 MHz to 1,990 MHz
AWS: UL: 1,710 MHz to 1,780 MHz DL: 2,110 MHz to 2,180 MHz
2,600 MHz: UL: 2,500 to 2,570 DL: 2,620 to 2,690
|Mode||850 MHz: UMTS, LTE FDD, LTE NB-IoT, UL, UM, LM, and ULM
PCS: UMTS, LTE FDD, LTE NB-IoT, UL, UM, LM, and ULM
AWS: UMTS, LTE FDD, LTE NB-IoT, UL, UM, LM, and ULM
2,600 MHz: LTE FDD
|IBW||850 MHz: 25
2,600 MHz: 70
|TX/RX channels||LTE NB-IoT: 2T2R
LTE FDD: PCS/AWS/2,600 MHz: 2T2R
850 MHz: 1T1R/2T2R
|Carrier Capacity||UMTS (BBU access): 8 carriers (1T1R/1T2R)
LTE NB-IoT (BBU access + RF input): 4 (carriers + subbands) (2T2R)
LTE FDD (BBU access + RF input): 12 (carriers + subbands) (1T1R/2T2R)
UMTS (RF input): 12 subbands (1T1R)
In UMTS, up to two carriers are supported per subband.
UMTS 1T2R consumes two subbands.
LTE FDD 1T1R is supported only on 850 MHz.
|Output Power||850 MHz: 2 x 70 mW
PCS: 2 x 175 mW
AWS: 2 x 175 mW
2,600 MHz: 2 x 175 mW
|UMTS Receiver Sensitivity with One Antenna||-112 dBm|
|LTE FDD/LTE TDD Receiver Sensitivity with One Antenna||-94 dBm|
|NB-IoT Receiver Sensitivity with One Antenna||-119.3 dBm|
|Power Supply||PoE power supply: –48V DC|
|Dimensions (H x W x D)||290 mm x 210 mm x 87 mm|
|Weight||≤ 7 kg|
|Typical Power Consumption for an RRU||Typical Power Consumption (50% Load): 71
Maximum Average Power Consumption (100% Load): 75
|Operating Temperature||With sunlight exposure of 1,120 W/m2: –40°C to +50°C
Without sunlight exposure: –40°C to +55°C
At a temperature from –40°C to –20°C, the pRRU can work without fulfilling performance requirements. At a temperature from –20°C to +55°C, the pRRU can fulfill the performance requirements.

|Surge Protection Specifications||Differential mode: 0.5 kV (1.2/50 μs)
Common mode: 1.0 kA (8/20 μs) for grounding a pair of PGND cables 3.0 kA (8/20 μs) for grounding eight PGND cables
|Number of CPRI Ports||RJ45: 1
|CPRI Data Rate||RJ45: 10.1 Gbit/s
SFP: 10.1 Gbit/s
|Topology||RJ45: Star topology
SFP: Star topology
|Maximum Distance||RJ45: At least CAT6a S/FTP shielded Ethernet cables are used. The maximum Ethernet cable length is 100 meters and can be extended to 200 meters through a 10.1 Gbit/s extender.
SFP: The maximum distance between a pRRU and an RHUB is 200 meters if a 1.5 square-millimeter optical/electrical hybrid cable is used.
