1 Introduction
1.1 Positioning
To keep abreast of rapidly advancing mobile communications technologies, mobile operators
are continually seeking partners who efficiently and cost-effectively provide cutting-edge
technologies with which to build high-quality, multimode-enabled, and future-oriented mobile
networks.
Upholding the concept of continuous innovation based on customer requirements, Huawei has
developed the future-oriented LampSite solution by integrating radio resources and multiple
technologies. This solution is designed to expand system capacity, fill in coverage holes, and
provide in-depth indoor coverage for multiple networking modes, such as GSM, UMTS, and
LTE.
The LampSite solution uses an optimized hardware and software architecture, featuring a
simple architecture, easy deployment, low capital expenditure (CAPEX), and in-depth
multi-mode coverage.
1.2 Benefits
Adopting a cutting-edge modular design, the LampSite solution is applicable to multiple
networking modes and can use a few different modules to accommodate all of the different
base station models. The solution is applicable to various installation scenarios, which
significantly reduces the network construction costs and Operation Expenditure (OPEX) of
operators during site acquisition, capacity expansion, and environment protection.
Easy Deployment
Network elements (NEs) are connected by optical fibers or network cables, which are
easy to deploy and low cost.
The pRRU supports both power over Ethernet (PoE) and AC-DC adapter power.
The pRRU has a modular design and supports flexible multi-mode configurations.
The LampSite solution is managed by the same operations support system (OSS) as the
macro network, and the entire network achieves E2E management.

High Performance
Cells can be split to expand system capacity.
The LampSite solution produces little background noise and has a high access success
rate and a low call drop rate.
The LampSite solution supports CPRI-MUX convergence and CPRI compression.
Smooth Evolution
With boards of different modes configured, multiple networking modes can coexist in one
BBU3900.
After their software configurations have been modified based on the software-defined radio
(SDR) technology, radio frequency (RF) modules support flexible multi-mode configurations.
Collaboration
Collaboration between indoor micro base stations in buildings improves the experience of
edge users and reduces the deployment cost of these base stations.
Collaboration between micro and macro base stations indoor and outdoor improves the
experience of their edge users and reduces the cost of network planning.

2 Hardware Architecture
2.1 Overview
2.1.1 Product Architecture
In the LampSite solution, the base station comprises the baseband unit (BBU), pico remote
radio unit (pRRU), and RRU HUB (RHUB). These modules can be flexibly combined to meet
different scenario requirements.
Figure 2-1 shows the product architecture of the LampSite solution in UMTS, LTE, or
UMTS+LTE mode.

NOTE
The hardware shown in Figure 2-1 can be applied in all modes, which is a reference only. The BBU can
be configured with baseband boards at different modes to meet requirements of different scenarios, and
the pRRU can be configured with different RF daughter boards at different modes to support multimode
applications. The connection principles for the LampSite solution are as follows:
The distance between the BBU and the lowest level RHUB cannot be greater than 10
km.
A maximum of four levels of RHUBs can be cascaded. However, pRRUs cannot be
cascaded.
One RHUB provides eight CPRI_E ports (CPRI_E0 to CPRI_E7), with each port
connected to one pRRU.An RHUB can be connected to a maximum of eight pRRUs.
The pRRU and RHUB are connected by CAT5e cables. With the internal PoE module
providing power, the distance of the two devices can be extended by the Extender up to a
total distance of 200 m.

2.3 RHUB3908 Equipment
The RHUB3908 converges the common public radio interface (CPRI) data from the RF
remote device. The main functions of the RHUB3908 are as follows:
The RHUB3908 works with the BBU and pRRU to provide indoor coverage.
In the downlink, the RHUB3908 receives the baseband data from the BBU, splits the
data into different routes, and sends it to pRRUs. In the uplink, the RHUB3908
converges the data from pRRUs and sends the data to the BBU.
The internal PoE module in the RHUB3908 provides power to the pRRU.

2.4 pRRU3901 Equipment
The pRRU, a remote radio unit, processes RF signals as follows:
The transmit channel receives the baseband signals from the BBU and performs
digital-to-analog conversion. The baseband signals are up-converted to the transmit
frequency band using the zero IF technology. The pRRU then filters and amplifies the
signals, which are sent to the antenna for transmission.
The receive channel receives the RF signals from the antenna. Then, the RF signals are
down-converted to baseband signals and sent to the BBU for processing after being
filtered and amplified.
NOTE
The CPRI data can be transmitted only using the Ethernet cable.
pRRU3901 supports the following:
Built-in or external antennas
PoE and AC/DC adapter
Flexible multi-mode configurations, with built-in RF cards for multiple radio access technologies
(RATs)
A pRRU supports only two RF cards in the current version.
