1 IntroductionThe MRFU can be used in an indoor cabinet or a protective outdoor cabinet. The MRFU can
modulate, demodulate, combine, and divide baseband and RF signals. It also processesbaseband and RF signal data. With the Software Defined Radio (SDR) technology, the MRFU
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 thecondition 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 theBER is not higher than 0.001.
The receiver sensitivity of LTE should be obtained from the LTE marketing personnel.
2.4 Output Power
MRFU modules operating in GSM mode and in the 900 or 1800 MHz frequency band comply withthe standard EN 301 502 V9.2.1.
MRFU modules operating in GSM mode and in the 850 or 1900 MHz frequency band comply with
the standard 3GPP TS 45.005 V10.2.0 & 3GPP TS 51.021 V10.2.0. MRFU modules operating in UMTS, LTE, or Multi-Standard Radio (MSR) mode and in 900 or 1800
MHz frequency band comply with the standard ETSI EN 301 908 V5.2.1.
MRFU modules operating in UMTS, LTE, or Multi-Standard Radio (MSR) mode and in 850 or 1900
MHz frequency band comply with the standard 3GPP TS 37.104 V10.4.0 & TS 37.141 V10.4.0.
For S1, S2, S3, S4, S5, and S6, the GSM output power in 8PSK mode is the same as that in GMSKmode with the improvement in the hardware capability. For S7 and S8, the GSM output power in
8PSK mode is the same as that in GMSK mode with the optional feature Enhanced EDGE Coverageenabled.
*: The UMTS mode is supported in terms of hardware.
The output power is 1 dB lesser than the standard power when the MRFU is located at a height of3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFU is located at a height
of 4500 m to 6000m.
Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and trafficmodel 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, powersharing cannot be used together with functions concentric cell, Co-BCCH, tight BCCH frequency
reuse, or enhanced measurement report. In GBSS9.0, power sharing can be used together withfunctions concentric cell, Co-BCCH, tight BCCH frequency reuse, and enhanced measurement
report. In GBSS8.1 and GBSS9.0, power sharing cannot be used together with IBCA, dynamicMAIO, RAN sharing, or double-slot cell.
Power sharing assumes a random distribution of UEs in the cell.

2.5 Power Consumption
The typical power consumption and the maximum power consumption are measured when the base
station works at a temperature of 25C.
The typical power consumption for GSM is reached when the base station works with 30% load and
power control and DTX are enabled. The maximum power consumption for GSM is reached whenthe 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 power consumption for GSM is calculated based on the sharing power.
