Introduction

The MRFU V6 can be used in an indoor cabinet or a protective outdoor cabinet. The MRFU V6 can modulate, demodulate, combine, and divide baseband and RF signals. It also processes baseband and RF signal data. With the Software Defined Radio (SDR) technology, the MRFU V6 can work either in GU or GL dual-mode through software configuration modification.



The receiver sensitivity of GSM, as recommended in 3GPP TS 51.021, is measured in the central band (80% of the entire operating band, excluding the edge band) at the antenna connector on the condition that the channel rate is 13 kbit/s and the Bit Error Rate (BER) is not higher than 2%.



The receiver sensitivity of UMTS, as recommended in 3GPP TS 25.104, is measured in the entire operating band at the antenna connector on the condition that the channel rate is 12.2 kbit/s and the BER is not higher than 0.001.



The receiver sensitivity of LTE, as recommended in 3GPP TS 36.104, is measured under a 5 MHz channel bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.

2.4 Typical Output Power 

MRFU V6 modules operating in GSM mode and in the 900 MHz/1800 MHz frequency band comply with the standard EN 301 502 V9.2.1. MRFU V6 modules operating in UMTS, LTE, or MultiStandard Radio (MSR) mode and in 900 MHz/1800 MHz frequency band comply with the standard ETSI EN 301 908 V5.2.1 and 3GPP TS 37.104.



In Error: Reference source not found, (1) indicates that the configuration is supported only when the MRFU V6 works in the 900 MHz frequency band.



For the MRFU V6 working in GSM mode, the maximum output power of each carrier on the MRFU V6 is 60 W when the S1 configuration is applied. Note that, if the output power of 60 W is required, the related license must be obtained.



The output power is 1 dB lesser than the standard power when the MRFU V6 is located at a height of 3500 m to 4500 m; and is 2 dB lesser than the standard power when the MRFU V6 is located at a height of 4500 m to 6000 m.



Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network planning can be based on the power specification achieved by dynamic power allocation.



In power sharing mode, 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 GBFD117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently 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 in GBSS8.1, GBSS9.0, and later versions.



Power sharing assumes a random distribution of UEs in the cell.



The output power per carrier in the output power table provides the maximum output power possible while ensuring the network performance.

2.5 Power Consumption 

The typical power consumption and the maximum power consumption are measured when the base station works at a temperature of 25°C.



The typical power consumption for GSM is reached when the base station works with 30% load. The maximum power consumption for GSM is reached when the base station works with 100% load.



The typical power consumption for UMTS is reached when the base station works with 40% load. The maximum power consumption for UMTS is reached when the base station works with 100% load.



The typical power consumption for LTE is reached when the base station works with 50% load. The maximum power consumption for LTE is reached when the base station works with 100% load.



The power consumption for GSM is calculated based on the sharing power.



The LTE power consumption is calculated based on 2 x 2 MIMO configuration. Two MRFUs are configured in each sector.



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

- GSM: one GTMU - UMTS: one UMPTb1 and one WBBPf3 in 3x1 and 3x2 scenarios, one UMPTb1 and two WBBPf3s in 3 x 3 and 3 x 4 scenarios.

- LTE FDD: one UMPTb1 and one LBBPd1 when one carrier is configured.
