The world, as we all know, has already been turned
into a global village and a new wireless paradigm is supposed to be
something that played a vital role in it.
Mobile communication and data communication are two
of the fastest growing areas in the communications industry. In
particular, mobile data communication, which includes wireless Internet,
carries a great deal of momentum. The media is keeping a vigilant eye on
the evolution of wireless data, and operators and various kinds of
enterprise have put wireless datacom at the top of their strategic
Wireless data communication combines mobile
communication and data communication by giving consumers easy access
through mobile phones, pagers, or other wireless devices to relevant
information on the Internet and intranets. Operators see wireless data
communication as an opportunity to create innovative services on top of
existing networks and investments. Doing so will give them a means of
differentiating themselves — for instance, to enhance their business
image, reduce churn, attract new subscribers, and increase traffic
volume per subscriber. Enterprises are increasingly looking for ways of
increasing employee productivity. Wireless data will enable
professionals to access corporate data, such as e-mail, production
status, price lists, and other critical information for doing business
while they are away from the office. Specific vertical segments, such as
financial institutions, have expressed interest in wireless data as a
way of distributing services. In this context, wireless data would
improve their overall image and increase the availability of services
through a rapidly growing low-cost distribution channel. These needs and
initiatives have created "phone browser technologies," such as
the wireless application protocol, or WAP.
NEW BUSINESS ROLES FOR OPERATORS
The intersection and merger of the wireless
telecommunications and Internet industries are forming the mobile
Internet market. In this realm, which is still very much characterized
by transition, the rules of the game are changed and several traditional
value chains have been upset. Consequently, on entering this realm, many
players feel uncertain of their role. Mobile companies have carefully
evaluated the situation and identified a number of emerging business
models that operators can adopt to position themselves in this turbulent
the business models of the mobile Internet are similar to those of the
Internet, some differences have been identified:
•The role of portals to the mobile Internet is more
prominent than that of portals to the traditional Internet.
•The emerging classes of service will have more impact on the success
or failure of the mobile Internet than mobility-enabling technologies.
•The mobile Internet represents a major opportunity for electronic
commerce (e-commerce). Opportunities are knocking the mobile Internet
industry and all we have to do is to tap these knocking opportunities.
WAP is assumed as a catalyst of the mobile Internet
and mobile companies are actively helping to shape the mobile Internet
industry with enabling technologies, such as WAP, Bluetooth, EPOC,
Parlay, GPRS, UMTS, and associated products. In particular, the wireless
application protocol is an early enabler with the potential both to
offer and unlock value in the emerging mobile Internet industry. In
fact, WAP is probably the one technology that will kick-start the new
industry and open the doors of opportunity.
I want to describe the new wireless paradigm with its
emerging business roles and opportunities and then provide a brief
background to WAP along with a comparison of competing technologies and
solutions but due to a shortage of time I would not go into the details.
This all becomes too tricky, technical jargons,
acronyms and so on and so forth, ok lets have a view of some basic facts
about communication, its origin and its development chronologically
along with some definitions. I am sure it would create a lot of interest
in the audience. Ok we must take a good start with definitions,
WHAT IS COMMUNICATION?
It is an exchange of ideas and information or the
exchange of meanings between individuals through common system of
symbols. The subject of communication has concerned scholars since the
time of ancient Greece. Until the modern times, however, the topic was
usually subsumed under other discipline and taken for granted as a
natural process inherent to teach.
Ok very interesting definition, what do you
understand by Audience?
Individuals or groups of individuals who are being
targeted to receive the intended information or messages.
The most important thing here is "Medium",
it is the path way through which the encoded messages reaches the
audience, this definition will lead us towards all this data
communication. Well its time to start our chronological analysis,
START OF ELECTRONIC AGE
During the electronic age in the 1900's people used
electronic knowledge to send messages to space. The radio, television
and other wonders of modern communication were possible.
All these facts and figures have been discussed just
to enhance the interest level of the listeners and now we must back to
our actual topic, ok now let me discuss the classification of the
CLASSIFICATION OF COMMUNICATION NETWORKS
Communication networks are usually defined by their
size and complexity. We can distinguish four main types:
Small. These networks are for the connection of computer subassemblies.
They are usually contained within a single piece of equipment.
Local area networks (LAN). These networks connect computer equipment and
other terminals distributed in a localized area, e.g. a university
campus, factory, office. The connection is usually a cable or fibre, and
the extent of the cable defines the LAN.
Metropolitan area networks (MAN). These networks are used to
interconnect LANs that are spread around, say, a town or city. This kind
of network is a high speed network using optical fibre connections.
Wide area networks (WAN). These networks connect computers and other
terminals over large distances. They often require multiple
communication connections, including microwave radio links and
The converging areas of IT and telecommunications are
possibly the fastest moving, most exciting areas of business and
industry today. In an increasingly global and knowledge-based society,
information management and transfer both are critical.
Information transfer at high speed, voice or data,
means telecommunications. Despite the well-publicized recent
difficulties, the revolution in telecommunications continues. New
technology and de-regulation of the telecom industry are opening up new
possibilities in many areas.
Users of telecommunications services are becoming
more demanding — of increased amounts of higher quality data,
transmitted ever faster. Interactive, broadband services for business
and home — e-commerce, entertainment and location-based services —
are expected, and in some cases, are already with us. While talking on
the topic of data communication we just can't ignore the role of
THE ROLE OF SATELLITES
Satellite communications (satcom) allows people and
businesses to exchange or broadcast information via satellites. This
information can be images and television, voice and telephony, Internet,
computer data, or a multimedia combination of several data types.
Satellite communication is one of the most versatile
communications technologies. Satellites are used for all sorts of
telecommunication systems with very different characteristics: from long
distance, high capacity telephone connections between remote countries
to very low rate data monitoring systems or mobile telephony.
Normally satellite communication is part of the
global telecommunications infrastructure — users will not be aware of
whether information is reaching them through terrestrial means or via
satellite, or indeed, through a combination of both. However in the last
few years satellite systems have been incorporated into millions of
homes and businesses throughout the planet. Satellite television now
reaches 100 million European homes — 50% of households, either
directly (37 million dishes point to the sky all over Europe) or through
cable distribution systems. Additionally, the rapid development of the
Internet has driven demand for satellite services for the distribution
of data to servers on the edge of the network.
The Satcom sector is expanding rapidly, with the
majority of growth expected from the demand for broadband services. For
example, subscribers to interactive multimedia services via satellite
could exceed 2 million by 2006, though some estimate the demand to
exceed 10 million.
Satellite communications has a number of specific
advantages over alternative terrestrial systems;
From their position in the geostationary orbit the satellite illuminates
countries or continents with their signals they are optimal for
broadcasting, TV, radio data or any other new service.
They permit the quick deployment for new systems or new services. An
example of this is digital television. Service providers and
Broadcasters such as BskyB, Canal+ and Direct TV all selected satellites
because they are the best way to make these new services available to
the most people, in the shortest period, at the lowest price.
The versatility of satellite communication systems makes them very
adequate to provide quick deployment of infrastructure for emergencies,
disasters or when specific high capacity links are required (such as
transmitting news,sports or other events from any place in the globe etc
— this is referred to as Satellite News Gathering Systems).
Suitable for all sorts of system architectures such as public networks,
corporate networks or client-server systems.
The cost of the satellite links is independent from their distance.
While high capacity trunks are usually being replaced by optic fibre
systems, satellites continue being a key element of thin routes of
public networks in many countries since they are the most economic, and
often the only solution.
Mobile Satellite Telecommunication Systems, such as INMARSAT, provide
the means to communicate with ship, planes and other vehicles no matter
where they might be.
Future systems will exploit these characteristics for
the benefit of users. Interactive broadband systems tend to offer high
user capacities at very low cost — low cost terminals and low cost
services. These are based on an evolution in the technology allowing
satellite capacities and performances 10-20 times greater than is
On the basis of the development of these and many
other applications, the market for satellite-based broadband interactive
services is predicted to be worth 18 billion Euro by 2007.
As with many areas of the broader IT and
telecommunications field, much of the interesting innovation for
satellite services is taking place close to end-users at the application
development, and service provision, end of the value chain. In order to
add sufficient value, many service providers are looking at the
development of end-to-end services, where content becomes an integral
part of the offer.
The advent of 3rd generation mobiles, and the
increased amount of data being transmitted for broadcast and
bandwidth-hungry applications, present many new opportunities for
satellites, as part of the infrastructure needed to support this new
DSL, Cable, and Satellite are the three basic
technologies vying to provide you with high-speed data connectivity. DSL
will come from the phone companies, Cable will come from your cable
provider and Satellite communications will come from other sources such
as Hughes Electronics (Direct PC/TV people).
There's not necessarily going to be one technology
better than the other, but it's a matter of which one serves your needs
best, which one is available to you, and at what cost.
The large providers are inking deals left and right
with each other to ensure they capture this market. Dell and Compaq will
both include DSL "modems" in their computers and @Home (data
via cable) will soon be providing its service in retail stores, it means
— no more "cable guy".
Once the data reaches at home or at office, its going
to have to reach the various computers and other electronic devices
waiting to receive. There are several technology solutions available now
and being designed for the future to provide in home networking
The traditional LAN solution with a hub and NIC card 2)
Networking via AC power circuits in the home, with adapters plugged into
wall sockets 3)
Wireless solutions that use radio air waves to communicate 4)
and a networking solution that leverages your existing phone lines.
Like with high-speed data communications, there's
really not one solution that's best. I know that the wireless solution
will be the most expensive — but for your situation wireless may be
the best option. As far as Phone line or AC circuit networking — as
long as they connect your computers, make you productive, and have
industry support it really doesn't matter — to a degree. Once you talk
about wiring your entertainment center and alarm system, these
technologies have glaring differences, but this discussion is about
computers. So I must not go into further details because I don't want to
create a hostile and antagonistic environment anymore. So its time to
wind up with the words,
Browser technologies for handheld devices are one of
several key enablers for the mobile Internet. Of the competing browser
technologies, WAP is almost certain to emerge as the dominant solution
for second-generation systems. Over time, WAP will maintain its position
and evolve to adopt the characteristics of third-generation wireless
Certain key characteristics that have been observed
in newly emerging business models are as follows:
•The role of mobile portals is more important to
the mobile Internet than that of traditional portals to the Internet.
•Several new classes of service will accompany the rise of the mobile
•The mobile Internet vastly improves the potential of mobile
As new business models take form, network operators
are finding themselves in a key position to serve as mobile Internet
payment and transaction centers, mobile Internet portals, and sites for
mobile Internet-based e-commerce.
The services have already evolved with the
introduction of GPRS, Bluetooth, and third-generation wireless
technology. Application developers who develop WAP services will later
develop services for EPOC, GPRS, Bluetooth, Parlay, and third generation
systems. WAP is thus more than just another wireless technology; it is
the catalyst of the mobile Internet. Within two to three years, WAP will
have become a convenient commodity among mobile end-users, significantly
changing the way they approach and carry out numerous daily tasks.
