Data Traffic Offload for Hot Spots

Small Cells

Small Cells I Introduction

One big challenge mobile operators are facing is the growing

demand for smartphone-driven data traffic. Often, the user

requirements are bound to specific busy hot spots. One possible

approach to deal with this is the realisation of small cells. By

implementing small cells, operators can provide a capacity increase

as well as an enhancement of coverage, thereby improving the

customer experience.

Besides the backhaul of the small cell, one of the main challenges

is the smooth integration of the site into the urban scenario. Com-

pact antennas which can easily be installed are an important fac-

tor. Possible scenarios are mounting the antenna at house walls

or existing infrastructure like advertising pillars, signs for public

transport, bus shelters, street lights or similar. Another possibility is

to hide the antennas completely in existing infrastructure or even

in the ground.

Introduction

Kathrein offers a broad portfolio of different antennas for small

cell applications with low visual impact as well as antennas for

hidden in-ground installation or installation into ad space. In

order to optimise the PIM performance of the system, the latest

small cell antennas are equipped with 4.3-10 connectors.

Main Use Cases of Small Cell Antennas

▪ Line-shaped scenarios, e.g. passage in a pedestrian zone, street

▪ Open places (small or big area), e.g. forecourt, town square,

campus areas, event hotspots, park areas

Antenna Pattern Types

Depending on the existing infrastructure and street furniture,

different antennas are available:

▪ Omnidirectional

▪ Bi-directional

▪ Sectorised, e.g. two-sector, tri-sector

▪ Directional

The main part of small cell antennas provides dual polarisation

for optimised MIMO applications.
