Our life is changing

2

Smartphones & Tablets enable access to data stored anywhere from any

point as well as controlling other devices

Growing demand of downloading digital multimedia data from the internet

instead of buying „static“ medium like CDs or DVDs

Cloud Computing allows storing and executing private as well as business

data inside the internet

The internet is everywhere – we get used to access the internet anywhere,

anytime: on our TV, on the mobile phone, while we are on vacation

The change and transition to decentralized networks in power distribution

requires communication on the power networks

Why should these services communicate with each other?

Multimedia

New services can only be created when they can interact:

Examples:

Connectivity in the game console to be able

to access the internet for online

shops/stores or multiplayer games

How to reach every point in the home?

8

Pure wireless

solutionPure wireline solution

One access point can not reach any

point in the home

A wired solution is not or not well suited

for mobile devices

=> Combination of several access

points can do better

=> Use existing cable infrastructure

To reach a full coverage of the home it is necessary to combine

wired and wireless technologies

Adding new devices into a home network

10

Adding a new device into the home network

must take care of the following aspects:

Plug & Play – the network and the new

device must have tools to do an automatic

detection

Authentication and authorization must

happen automaticially or has to be simple

Encryption for a tranmission on shared

media must be highly secure but easily to

be configured

2011/09/13

Remote Control

Example: Start heating at home on last

day of the vacations

Example: Hotline diagnostics

The center of home networking – the residential gateway

12

Control via

Apps

SW

The residential gateway device

has to fulfil several tasks:

Secure connection to the

internet

Authentification and

authorization of new devices

being added to the network

Platform to install apps on a

GW middleware which allows

the access and control of

devices in th enetwork (e.g.

DLNA, proprietary control for

heating, light, etc.)

Home Gateway with Middleware Framework for Control Apps (e.g.:

OSGi, Android@Home, etc.)

Internet

Every point can be reached

on a wireless network by

multiple distributed access

points in the home

Remote control capability by

connetion through the

internet

Find new devices and

integrate them by simple

procedures

All devices can talk on one

single network using one

common language - IP

Home Gateway as central device

International standards

guarantee interoperability

and ‚Economies of Scale‘
