Mobile and broadband subscribers versus
installed base of laptops


In the past few years many TV shows
and movies have suddenly been made
available over the Internet.
It has driven more types of devices to
be connected to networks, which in
turn will increase the business value of
a network to its nominal owners.

Trend of Home Network



All networks will be merge into the
Internet.
Server-to-server and peer-to-peer
architectures.
Sharing the increased value of a single
larger network will be worth more.

1.2 TECHNOLOGY ADOPTION TRENDS

Applying Moore’s law,the networking
and communication industries meant
doubling the price-to-performance ratio
every 18 months. The same is expected
to happen for the bandwidth-to-price
ratio in networking, communication,
and home networking industries.

Section 1.3
Social Network
What is a social network?




A human empowered network.
A platform specifically focused on the building and
verifying of social networks for whatever purpose.
A platform where people from all walks of life come
together to express themselves by means of sharing
videos, music, pictures, content
It provides the ability to collaborate using peer-topeer applications and services.
1.3.1 Business Applications



Businesses are beginning to use social networks as a
means to connect employees and to help employees
build profiles.
A network that connects businesses by industry,
functions, geography , and areas of interest.
Networks are usually free for businesses or at a low
cost.
These networks act as a customer relationship
management tool for companies selling products and
services.

Living in Real Time
1.5 LIVING IN REAL TIME




Living in real time means having access to network at all times
and having some control capabilities for home monitoring,
appliances, and other devices from remote locations.
Real-time information would include services such as news,
education, search engine, health care, travel, TV.
Real-time commerce would mean online payment and online
banking services. This will enable services such as online
reservation and payment for movies, games, music, ring tones,
entertainment, and ordering of goods and services.
Communication services include telephone, video telephony,
instant messaging, e-mail, multimedia services.
Section 1.6
Confluence of Events
Fixed–mobile convergence is created by the
confluence of events

1.6 CONFLUENCE OF EVENTS


For now, two approaches to client and
gateway functionality have emerged,
namely Unlicensed Mobile Access (UMA)
and SIP.
These approaches will ultimately
converge into IP Multimedia Subsystem
(IMS).
Section 1.7
Application and Service
Convergence
1.7 APPLICATION AND SERVICE
CONVERGENCE


Application convergence combines electronic
subsystems that meld voice, data, and video
into all sorts of electronic equipment.
Different technologies combine for one
application such that various traffic types
such as video,communication, and computing
are in the same SoC(System-on-Chip) design.
Convergence of applications, services,
and networks

Section 1.8
Network Convergence and
Regulations
1.8 NETWORK CONVERGENCE AND
REGULATIONS

Dual-mode phones are able to connect to
mobile networks and Wi-Fi APs at home,
public Wi-Fi hotspots, airports, hotels



Enable an active call on any dual-mode phone to
be switched (handover) back and forth between
fixed broadband and mobile networks
Reduce usage of licensed spectrum
Enable users to call using a single device at the
lowest cost and to maintain the call connectivity.
Section 1.9
Terminal Convergence
Terminal Convergence



Include multiple wireless interfaces in
products
Balance functionalities of devices with cost,
power consumption, and the customer’s
ergonomic expectations.
More and more radio technologies will find
their way to smart devices, and handheld
terminals will lead the way by implementing.
Convergence possibilities





interworking between indoor(LAN) and
outdoor(WAN) and interconnecting multiple
devices at home.

Home Computing

Basic Requirements on Home Networking from the
computing perspective：
 Interworking and distribution of high bandwidth to
multiple devices
 Interworking between home IP gateway and WAN
connection
 Securing in-home communication and via WAN
connection
 Wireless enhancements for range and speed
 Wired and wireless home network media
 Distributed file sharing
1.10.2 Home Entertainment

Entertainment on demand is on the march
with the consumer.


An example of a networked platform that offers
consumer sticky application around digital media
is consumer place-shifting device or software.
This will be the first time the PC industry puts
ready-to-go in-built capabilities such as
anytime, anywhere media streaming on PC
into the hands of consumers, allowing them
indoor and outdoor content delivery.
1.10.2 Home Entertainment


with consumer demand toward producing
personal video content, sharing files, P2P
video file transfer, IPTV, consumers are
starting to see a large collection of their
digital media files stored across multiple
devices.
This will generate demand for low-cost
networked storage devices that can be
accessed through various media players
through different mediums
1.10.3 Home Communications

Communication in-home involves the
following:
1.
2.
3.
Integrated communications for fixed and
mobile.
Instant communications with federated
user groups.
Presence integrated into voice
communications.
1.10.4 Home Monitoring and Management

In monitoring and management, the
following items have been
characterized:
1.
2.
3.
Remote surveillance
Home systems management
Heating, ventilation and air-conditioning
(HVAC) and lighting control
Section 1.11
Connected Home
1.11 CONNECTED HOME

Convergence of communication, computing technologies, and
consumer electronics.


Vision of the Future
1.12 VISION OF THE FUTURE



1. It is logical to assume that all devices will
eventually be networked, but it will most probably
start with devices that either are already intelligent
(computers) or are very important to us (e.g.,
television, phone, and music system).
2. A possible way for the network to maximize its
value is through server-to-server and peer-to-peer
networking.
3.Devices, systems, services, and applications
capabilities are defined by software.
