Overview
The RRU5502 is an outdoor remote radio unit. It is the RF part of a distributed base station
and can be installed near the antenna. The RRU5502 modulates and demodulates baseband
and RF signals, processes data, amplifies power for signals, and supports voltage standing
wave ratio (VSWR) tests. With the software-defined radio (SDR) technology, the RRU5502
can work in GL, UL, GUL, LM, GLM, or ULM mode through software configuration.
The RRU5502 adopts a 4T4R design, which further improves the output power and carrier
capacity.
The software version of the RRU5502 is SRAN13.1 and is compatible with the N–1 and N–2
versions of MBTS, MBSC, and OSS NEs. Therefore, the RRU5502 can be used with products
of SRAN11.1, SRAN12.1, and SRAN13.1 versions. All these three versions include the
RRU5502 software components. The RRU5502 used in these versions has no impact on
product KPIs.


The GSM receiver sensitivity, as recommended in 3GPP TS 51.021, is measured at the antenna
connector assuming that the channel rate reaches 13 kbit/s and the bit error rate (BER) is lower than
or equal to 2%.

The UMTS receiver sensitivity, as recommended in 3GPP TS 25.104, is measured at the antenna
connector assuming that the channel rate reaches 12.2 kbit/s and the BER is lower than or equal to
0.1%.

The LTE FDD receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 5 MHz
bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.

The LTE NB-IoT receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 200
kHz bandwidth and a 15 kHz subcarrier spacing based on the FRC A14-1 in Annex A.14 (π/2 BPSK,
R = 1/3, 1 RB) standard.

2.4 Typical Output Power

The RRU5502 operating in the 1800 MHz frequency band cannot work in GSM only mode.

The RRU5502 that works in UMTS, LTE FDD, or multi-standard radio (MSR) mode and operates in
the 2100 MHz frequency band complies with the ETSI EN 301 908 V5.2.1 and 3GPP TS 37.104
standards.

The RRU5502 that works in LTE FDD mode and operates in the 1800 MHz frequency band
complies with the 3GPP TS 36.141 standard.

If an RRU5502 is located at an altitude of 3500 to 4500 meters, its power reduces by 1 dB. If an
RRU5502 is located at an altitude of 4500 to 6000 meters, its power reduces by 2 dB.

The output power per carrier in the following output power tables indicates the supported maximum
output power 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.)
