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.

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.

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.

1.2.1 WCDMA and LTE

Easy Deployment Network elements (NEs) are connected by optical fibers or Ethernet 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.

LampSite Solution

Product Description 1 Introduction



2

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.

1.2.2 WLAN

In SRAN9.0 or later, Wi-Fi daughter boards can be configured on the pRRU. That is, the

pRRU can work on the Industrial Scientific & Medical frequency bands (ISM bands) 2.4 GHz

and 5 GHz. With OFDM, DSSS, and CCK demodulation technologies supported, the

LampSite solution provides a data transmission rate of 300 Mbit/s on each frequency band.

OFDM refers to orthogonal frequency division multiplexing, DSSS refers to direct sequence spread

spectrum, and CCK refers to complementary code keying.

Compliance with the IEEE 802.11 a/b/g/n standards, the LampSite solution uses two RF

units to provide a maximum transmission rate of 300 Mbit/s on each frequency band in

multiple input multiple output (MIMO) 2x2 mode when OFDM is used.

The LampSite solution works with brilliant performance and high stability. The

processor provides high throughput and robust load capability. The stable signal strength

and quality ensure reliable running of the wireless networks. Automatic power and

frequency adjustment and load balancing enable flexible and stable large-scale networks.

A rich variety of network security features are provided, such as protection against XML

denial-of-service (XDos) attacks, firewall, media access control (MAC) address filtering,

IP address filtering, and link integrity protection.

WLAN authentication and privacy infrastructure (WAPI), wired equivalent privacy

(WEP), Wi-Fi protected access (WPA), WPA2, and 802.1X are supported to ensure

network security.

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.

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 daughter boards for multiple radio access

technologies (RATs)

Wi-Fi daughter boards supporting data transmission services

2.4.1 pRRU3901 Exterior

A pRRU can have two transmission ports or three transmission ports. The pRRU with three

transmission ports can be configured with a Wi-Fi daughter board to connect to the AC and

provide Wi-Fi services. Unless otherwise specified, this document uses the pRRU with three

transmission ports as an example.

ATBR in the RX and TX Channels column indicates that this RF module has A transmit channels

and B receive channels.

C x D W in the Maximum Output Power column indicates that this RF module has C TX channels

and the maximum output power for each TX channel is D mW.

The maximum output power of the pRRU can be measured at the antenna port or calculated by using

the following formula:

Maximum output power of the pRRU = Maximum output power of the PA - Internal loss

The LTE receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 5 MHz

channel bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.

The 11 configuration indicates that two continuous carriers are configured and the spacing between

the center frequencies of two neighboring carriers is 5 MHz. In 101 or 1001 configuration,

discontinuous carriers are configured. The value 0 indicates the spacing of 5 MHz. For example, the

1001 configuration indicates that two discontinuous carriers are configured and the spacing between

the center frequencies of the two carriers is 15 MHz.
