Huawei LampSite

Future-proof Indoor SolutionLampSite is a Huawei-

developed leading in-depthcoverage solution. This

solution adopts BBU+RRU

architecture, of which the ase

station consists of a aseand

processing unit !BBU", pico

remote radio unit !pRRU", and

RRU HUB !RHUB". #s a new

platform to allow indoor

solutions to evolve to LT$,

LampSite is eas% to deplo%,supports smooth evolution,

and allows high networ&

performance and huge

capacit%. Therefore, it is ideal

for large and medium indoor

scenarios, li&e large office

uildings, large venues, and

transport hus.

'n indoor scenarios, radio

signals are su(ect to uildingloc&ing and asorption

during propagation, causing

signal attenuation and

coverage holes. )articularl% in

large uildings, radio channel

congestion fre*uentl% occurs

due to ecessive moile

densit%. To address these

issues, there is an increasingl%

strong demand on indoor

coverage s%stems.

Platform for evolution of

indoor networks

 #long with large-scale

transition from to ,

accelerated LT$ application

process, and increasing

investment pressure on

operators, indoor solution

must e future oriented andsupport evolution to LT$-#,

LT$-B, and even /.

LampSite uses BBU+RRU

architecture, which ma&es it

eas% to achieve smooth

evolution from various R#Ts.

LampSite is ale to provide 0,

, and services andsupports 1i-2i and emerging

L##. Through software upgrade,

LampSite can provide multiple

LT$-# features, such as 3U-

3'34, 5o3), and 5#. 1ith those

features, LampSite significantl%

raises data rate toward users and

spectral efficienc%.

S%stem architecture is unified

etween LampSite and 3acros.Therefore, solutions and features

can remain consistent etween

indoor and outdoor s%stems.

Such strength means great

convenience for operators to

s%nchroni6e indoor and outdoor

technologies.

High performance and huge

capacity

LampSite allows multiple pRRUs

to serve one cell, with a cell

served % each individual pRRU

having the same cell ph%sical cell

'7. 'n the uplin&, LampSite adopts

independent demodulation of

signals from multiple pRRUs and

then comines demodulated

signals in the BBU without having

an increase in ac&ground noise.

1ith these functions, LampSite

remar&al% improves downlin&

provides etter uplin& reception

networ& performance. 1ith

fleile, huge capacit% feature,

LampSite is ale to asor most

of indoor service traffic. 3U-

3'34 and 5# further position

LampSite to provide high-rate

service eperience to users. 1ith

indoor dual-and 5#, LampSite

even provides a pea& data rate of

as high as 99 3it:s.

Smart O&M

LampSite supports pRRU-level networ& management,

which allows users to get

clear real-time information

aout statistics of handovers

and call drops and device

operating status of the indoor

networ&. LampSite can share

an 83S with macro networ&s

so that indoor and outdoor

networ&s adopt a unifiednetwor& management s%stem

High Return on Investment (ROI

Traditional 7#S re*uires numerous R2 feeders and special

devices li&e cominers and splitters that must e installed

% professional engineers. 'n this sense, 7#S is orn to e

maligned with high costs and long construction time.

Statistics show that 7#S engineering cost accounts for

over =9> of the total construction ependiture. 'n addition,

reconstruction to support 3'34 re*uires further investment

to deplo% another 7#S s%stem.

LampSite adopts optical fier and $thernet cales that do

not re*uire special engineers to complete installation, which

can remar&al% shorten deplo%ment time and reduces

engineering difficulties. Statistics show that LampSite can

reduce construction period % ?/ to 9 times. 2or eample,

the cale routing and device installation that ma% ta&e one

month to complete can e finished within a single da%. Still

more, LampSite does not re*uire caling ad(ustment to

achieve s%stem upgrade. Rather, an upgrade in LampSitecan e done % adding new R2 models to the pRRUs, as

simpl% as changing light uls. Besides, LampSite

simplifies engineering maintenance so that operators can

ma&e their investment count % focusing on device capacit%

epansion and s%stem upgrade, which is essential to

measural% increase their R4's.
