Mobile cellular network

First Generation: provided wireless communications without mobility, a luxury service

Second Generation: cellular networking invented by Bell Labs in 1972 made wirelesscommunication accessible to main stream public (at early 1990s)

Third Generation: introduced data services (around 2000)

Fourth Generation: enhanced data capacity & higher mobility support


3/12

Driving factors of todays mobile networking

User's behavior: moving from voice to

multimedia applications, requiring

ubiquitous coverage

Operator business model: unlimited data

offers to save declining ARPU

Handsets & applications: iPhone, iTunes,Mobile TV, Social networks, etc., are

throughput-greedy

Technical issues: what else to increase

the network capacity?

Regulation: installation of new high

power macro BS will be more difficult

Mobile communication networking is leaded in a future of small cells

Max top down TAM Picocells+Microcell: M$ 1100 in 2012 (~3% of Wireless TAM **)

Little confidence in market view early bet by an optimistic analyst

Analysts views are converged on the strong demand for femtocells from 2011-2012.

Technical challenges

High network complexity

high density & randomness of cell sites

Spectrum sharing

Macro cell small cell spectrum sharing will be

needed for system integration, interference

avoidance

Massive SON (Self-organizing Networks) SON is a key enabler for efficient network

management & OPEX reduction

Networking

Cross radio layer mobility and beyond handover

Local breakout and beyond mobile-IP

Wireline integration

Joint optimization for macro and small cell

MIMO for small cell

Regular macro cells


11/12

Summary

Small cell networking is promising

Network architecture, NOT cellular technology

Simple logic: reduce cell size to increase the

network capacity

Small antenna & site allow for coverage hole

avoidance & energy efficiency

Enabler: efficient backhauling (e.g., GPON),

advanced network management (e.g., SON,new PHY technologies)

Different concepts for different usages

Femtocell: private home network, small

transmission power & range (~ some meters)

Pico cell: public indoor & outdoor for hotspots,

higher trans. power & range than Femtocell

None of the solutions available today

address small cells requirements

Seamless handover is a big technical concern

Cross layer small cell macro cell operation

Real SON solutions for network deployment &

management at low cost

Market

Some operators believe commercial

deployments not feasible until 2011

Low cost is critical - one of the inhibitors of

femtocells and picocells market traction.

Big thread from WiFi free access

Too early to benchmark small cell networks

solutions
