BTS base station RRU5909 series Multi-mode(2*60w) 

Brand new and used RRU5909 B1 B3 B8 900Mhz 1800Mhz 2100Mhz are available. 

The RRU5909 is an outdoor remote radio unit which is powered by a power cabinet. It is the  RF part of a distributed base station and can be installed near the antenna. The RRU5909  performs modulation, demodulation, data processing, and combination and division of  baseband signals and RF signals. With the software-defined radio (SDR) technology, the  RRU5909 can work in GU, GL, UL, or GUL dual mode through software configuration.  The RRU5909 adopts a dual-transmitter and dual-receiver design, which further improves the  output power and carrier capacity.  

Physical Ports

The RRU has a modular design. Its external ports are located at the bottom of the module and  in the cabling cavity.

Power Consumption 

The typical power consumption and the maximum power consumption are measured when the  ambient temperature is 25°C.  

The typical power consumption for GSM is measured when the load is 30%. The maximum power  consumption for GSM is measured when the load is 100%. 

The typical power consumption for UMTS is measured when the load is 40%. The maximum power  consumption for UMTS is measured when the load is 100%. 

The typical power consumption for LTE is measured when the load is 50%. The maximum power  consumption for LTE is measured when the load is 100%. 

This section describes the power consumption of an entire base station. Board configurations in a  BBU are as follows: 

 GSM: one GTMU board 

 UMTS: one UMPTb1 and one WBBPf3 boards in 3x1 and 3x2 scenarios; one UMPTb1 and two  WBBPf3 boards in 3x3 and 3x4 scenarios 

 LTE FDD: one UMPTb1 and one LBBPd1 boards when one carrier is configured

Typical Output Power

 An RRU5909 working in GSM mode and operating in the 900 MHz, 1800 MHz, or 2100 MHz  frequency band complies with the EN 301 502 V9.2.1 standard. An RRU5909 working in UMTS,  LTE FDD, or MSR mode and operating in the 900 MHz, 1800 MHz, or 2100 MHz frequency band  complies with the ETSI EN 301 908 V5.2.1 and 3GPP TS 37.104 standards. 

 For the RRU5909 working in GSM mode, the maximum output power per carrier is 60 W when the  S1 or S2 configuration is used. If the output power of 60 W is required, the corresponding power  license must be purchased.  

 If an RRU5909 is located at an altitude of 3500 to 4500 meters, its power reduces by 1 dB. If an  RRU5909 is located at an altitude of 4500 to 6000 meters, its power reduces by 2 dB.  

 Factors such as the inter-site distance, frequency reuse factor, power control algorithm, and traffic  model affect the gains of dynamic power sharing. In most cases, network plans are designed based  on the power specifications allocated by dynamic power sharing.  

 When the dynamic power sharing feature is activated, the power control and DTX functions must be  enabled. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the  GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense  Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In  GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these  features. In GBSS8.1, GBSS9.0, and later versions, the dynamic power sharing feature cannot be  used together with the GBFD-117002 IBCA (Interference Based Channel Allocation),  GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell  features.  

 Power sharing is performed on the assumption that UEs are randomly distributed in a cell.  

The output power per carrier in the output power tables indicates the maximum output power  supported to ensure network performance. 

 When two LTE FDD carriers are configured, it is recommended that the power spectrum density  (PSD) be set to the same value for the two carriers. Power spectrum density = Carrier output  power/Carrier bandwidth (1.4 MHz and 3 MHz bandwidths are considered as 5 MHz bandwidth in  this formula.)
