Live in fragments no longer. Only connect.
Edward Morgan Forster

We wove a web in childhood,
A web of sunny air.
Charlotte Bronte
Wow! Many of our readers will say, "I had no idea that this wireless stuff was so significant. I have
been using cell phones for years, but I never viewed cell phones as vehicles for connecting to the
Internet and browsing the Web. Now, all of a sudden, I learn the amazing statistic that the number
of people accessing the Web through wireless devices by 2002/2003 will be larger than the number
who access the Web through desktop computers! Who could have imagined this?"
So here you arefollowing the explosive development of the Internet fostered by the World Wide
Web. Yes, the world got a dose of reality in 2000/2001 as the stock market lunacy of 1999-2000
discovered gravity and fell back to Earth. For speculatorsof which there were far too many in
1999-2000this was a devastating crash. People "got hurt." But for people following the long-term
trends, it is absolutely clear that an increasing portion of business will be done on the Web, and
more of your personal lives will become Webcentric. Young people have not seen the ebb and flow
of business cycles. Their view is shortterm. Older folks have experienced business cycles. We see
forecasts that e-business will be $5-$6 trillion by 2004/2005; more than eighty percent of that will be
business-to-business (B2B) transactions.
This book has been a true labor of love. Although there are four authors on the cover, probably 30
people at Deitel & Associates, Inc. made significant contributions. We attended many trade shows
to be sure we were current with what is happening in the wireless field. Four of usHarvey and
Abbey Deitel, Kate Steinbuhler and Matt Kowalewskispent a week at the CTIA (Cellular
Telecommunications and Internet Association) trade show in Las Vegas. What a wonderful
educational experience for us alland a fun time. We visited every one of the 1000 (!) exhibitors at
the show. While we were there, though, we noticed something unusualthere were no publishers
exhibiting their books, nor was there a book store as there normally is at a major trade show. The
realization reinforced our commitment to this book.
We see a global explosion in the so-called "wireless Internet," but we do not see books geared to
preparing computer-science students, information technology students and professionals for the
wireless Web revolution. Wireless Internet & Mobile Business How to Program is intended for the
student or professional who sees the enormous potential of this exploding field.
Just look at the bullets on the front cover or the Table of Contents. There is an amazing range of
topics covered in this book. Every major technical thrust in wireless Internet programming is
covered in these pages.
1. i-mode. The Japanese i-mode system with over 24 million subscribers is the leading wireless
Internet system in the world by'a factor of three. You will learn the history of imode and how to
mark up text using cHTML.
2. Wireless Application Protocol (WAP) dominates wireless Internet access in the U.S. and Europe,
and also is popular in Japan. You will learn how to mark up text using the Wireless Markup
Language (WML) and how to create dynamic content on wireless clients with WMLScript.
3. Java 2 Micro Edition (J2ME). You will learn Sun's newest addition to the Java platform that
many people feel will eventually dominate in the wireless world. You may have heard the terms
"applets" and "servlets;" you will be introduced to MIDlets-a MIDP (Mobile Information Device
Profile) application.
4. XHTML. Most programmers have developed HTML-based Web pages. However, the W3C
(World Wide Web Consortium) has declared HTML to be a legacy technology that will undergo no
further development. HTML is being replaced by XHTMLan XML-based technology certain to
become the standard in the development of Web clients over the next few years. However, XHTML,
like HTML, is far too rich for wireless clients with their small displays and bandwidth limitations,
so the W3C has developed a concise subset of XHTML for wireless clientsXHTML Basic. Both
WAP and i-mode are converging on XHTML Basic in impending versions, so we cover XHTML
Basic markup in Chapters 24 and 25.
But the client side is only half the picture. What about the server sidewhere "heavy-duty"
business logic is implemented? Active Server Pages (ASP) is popular for implementing business
logic on Microsoft Web servers and Java dominates the world of nonMicrosoft Web servers. We
explore these powerful technologies by presenting two large, fully implemented and carefully
documented case studies. The ASP case study in Chapter 26 prepares wireless content for i-mode
(cHTML), WAP (WML and WMLScript) and XHTML clients. The J2ME Java case study uses
Java on the server side to prepare content for i-mode, WAP, XHTML and J2ME clients. It was
reported at the June 2001 Java-One trade show that 98% of i-mode server-side programming is
done in Javaa stunning amount, given the abundance of server-side programming technologies.
Many people believe that the wireless world will converge on Java and XML, so we have included
Appendix A, Java Programming, and Appendix H, XML.
If you are tired of tripping over wires and installing wired networks in your offices and your
homes, get ready for the Bluetooth wireless technology revolution. Bluetooth technology can
remove the wires connecting your mouse, your printer or any other peripheral device connections
to your computer. Not only this, but you will be able to network your office without wires, and your
carbecoming ever more electronic- and gadget-intensivewill no longer need complex wiring. You
will be able to use your cell phone to buy products from vending machines, to check into hotels and
gain access to your hotel room. The possibilities are endless. Already 2200 companies belong to the
Bluetooth Consortium.
We present yet another leading-edge technologyBREWthe Binary Runtime Environment for
Wireless&3151;created by Qualcomm. BREW enables wireless application developers to solve the
complex problem of developing applications that will run on disparate platforms. Developers need
only "write to" BREW which will enable disparate devices with BREW hardware and software
installed to run these applications despite the fact that the underlying hardware and software might
be quite different.
Although wireless devices have limitations, multimedia developers have nevertheless created
impressive wireless capabilities. Chapter 30, Multimedia: Audio, Video and Speech Recognition,
and Chapter 31, Flash, detail these interactive elements.
We have all experienced the e-business revolution. Next up is the m-business (mobile business)
revolution. In addition to our coverage of wireless technologies, we have included a dozen chapters
to help you prepare for m-business, including Introduction to mBusiness; Location-Identification
Technologies and Location-Based Services; e-Marketing and m-Marketing; e-Payments and
m-Payments; Security; Legal and Social Issues; International Wireless Communications; two
chapters of Wireless Communications Technologies; Palm

and Palm

; and Microsoft CE,
Pocket PC and Stinger.
The m-business topics we introduce apply many of the programming technologies you learn in
Wireless Internet and Mobile Business How to Program.
Companies are equipping their mobile
workers with cell phones and PDAs to provide their employees "anywhere, anytime" access to
business-critical information. With location-identification technologies and location-based services,
companies can track deliveries; marketers can use the mobile communications explosion as a new
and effective way to reach mobile customers because they know where the customers are at a given
time. Location-tracking capabilities also raise the issue of whether the applications constitute an
invasion of privacy. If used in certain arenas, it could indeed be intrusive. On the other hand,
tracking cell-phone users could save lives when accident victims cannot communicate.
Imagine if you could use your cell phone to beam payment information when buying merchandise
at a local store. M-commerce success hinges on whether cell phones will become widely used
payment mechanisms and whether payments can be sent and received securely. Payment and
security are discussed in Chapters 5 and 6.
The international community is the leader of wireless communications technology and use. In a few
countries, as many as three-quarters of the people own cell phones. For some people, cell-phone
calls are the first calls they make because of the relatively high cost of wired telephone service
outside the United States. International wireless communications is presented in Chapter 8.
Wireless communications encompasses numerous technologies that we discuss in Chapters 9 and
10. These chapters provide you with an understanding of the breadth of technologies used around
the worldhardware, cell-phone networks and wireless platformsfor wireless communications.
Soon your cell phone will be your electronic address book and calendaras personal digital
assistants (PDAs) and cell phones converge. Chapter 11 details the Palm

handheld and its
applications and Chapter 12 details the Pocket PC handheld and the "smart phone," the so-called
"convergence device."

For Wireless Internet/Web courses and advanced Internet/Web Programming courses focusing on
the wireless internet found in departments of Computer Science, CIS, MIS, IT, Business,
Engineering, and Continuing Education. While the rapid expansion of wireless technologies such as
cell phones and palm pilots offers many new opportunities for businesses and programmers, it also
presents numerous challenges related to issues such as security and standardization. Wireless
Internet & Mobile Business How to Program offers a thorough treatment of both the management
and technical aspects of this growing area, including coverage of current practices and future
trends. The first half of the groundbreaking text explores the business issues surrounding wireless
and mobile businesses, beginning with the decision to utilize specific technologies and the
application of business principles to wireless devices. Wireless Internet & Mobile Business How to
Program then discusses location-based services, a topic that will be revisited throughout the book
since so much of wireless and mobile business depends on knowing the specific location of the
customer.This portion of the book also addresses payment, security, legal and social issues,
international wireless communications and more. The book then turns to programming for the
wireless Internet and for mobile businesses, using the consistent and applied pedagogy that has
garnered acclaim from both instructors and students for the Deitels'How to Program series. (Freely
available online simulators of cellular phones and personal digital assistants (PDAs) make it
possible for students to learn to program these devices without needing to own them.)
Overcoming the cost per hire obstacle Business equals people. This means that in the face of tough
market conditions and ongoing challenges, the ability to attract the best talent innovating in the
recruitment market is key to competing with the best in the UK market. But how do you maximize
this strategy while keeping costs low at the same time? To achieve this it's imperative to understand
the real costs of recruitment as these often become misplaced when engaging in the recruitment
process. Concern about costs amongst senior HR professionals Managing costs was identified by
senior HR professionals as being their top organizational priority in the 12 months to 2011.
(Source: A Barometer of HR Trends and Prospects 2011, Chartered Institute of Personnel and
Development) A big part of this is the cost of recruitment. Not surprising when you consider that
the median recruitment cost of filling a vacancy is ?7,500 for senior managers/directors and ?2,500
for other employees (adjusting for accuracy) (Source: Chartered Institute of Personnel and
Development 2011 Resourcing and Talent Planning Report). While this cost has been found to be
decreasing compared with previous years, it is still a high proportion of overall HR costs. There's
no doubt that cost per hire is still a major obstacle to companies seeking to stay ahead in their
market. With 50% of organizations now reporting a reduced recruitment budget (Source:
Chartered Institute of Personnel and Development 2011 Resourcing and Talent Planning Report),
keeping costs low whilst maintaining quality of candidates is an important paradox for companies
to address in the coming months and years. Solving the quality/cost paradox: an alternative Some
businesses are starting to adopt an approach that does succeed in solving the cost/quality paradox.
Two companies, RSM Tenon and Gregs, have achieved a 40% reduction in their cost per hire. The
step is to address the misconceptions about the costs of recruitment versus the actual costs.
Addressing the myths: the perceived costs of recruitment There are plenty of misconceptions about
the costs of Online recruitment talent.In recent research, HR professionals were asked about their
future recruitment cost control predictions. Two respondents in three (66.2%) said that their
organization would look to reduce the cost of recruitment within the next 12 months (Source: Xpert
HR). So while many recruiters are keen to cut costs, what are the main misconceptions that persist
around the costs of recruiting and retaining talent? Myth 1) Getting the talent without the fees: It is
understandable that in tougher economic times, recruiters are keen to bring talent on board whilst
cutting the costs. Yet finding and retaining talent starts with a strategic recruitment funnel. On the
surface of it, this more DIY approach to finding talent seems to make sense. But dig a little deeper
and it's easy to see the potential risks of trying to reach the highest caliber of candidate without
specialist help, with issues such as staff attrition being a significant cost to business. This is about
settling for second best - and potentially achieving second rate results. Myth 2) High recruitment
fees: High recruitment fees are commonly viewed as a significant factor in high cost per hire.
Again, in more challenging economic times this is an understandable misconception. But, again
when we compare the overall costs of getting recruitment wrong (i.e. hiring the wrong person,
multiple rehires etc) an initial recruitment fee is a small cost. This is myth is possibly a popular one
because the recruitment fee is an overt part of the recruitment process, unlike the more hidden, but
very real issues that increase the cost of hiring. Myth 3) Small amount of resource: Another
common myth, a small amount of resource is again understandably viewed as a major cost in
recruitment. The amount of resource spent recruiting one person can end up equating to several
weeks of time once each stage of the recruitment process has been completed. Highlighting the
hidden costs of recruitment There are plenty of misconceptions about what really makes up the cost
of recruitment. But what about the hidden problems that create the real costs of finding and
retaining talented candidates? These are aspects that, unlike perceived causes of costly hiring, are
less obvious and on the surface, but which actually lead to long-term issues with recruitment - and
with the overall performance of an organization. Hidden cost 1) Lack of skills - wrong specification:
this is a massive hidden cost to recruiting companies. Hidden away right at the top of the
recruitment funnel, it is the stage that can result in a decision to recruit the wrong person by Web
recruit and bring the wrong set of skills into an organization. Added to this is the issue of creating a
job spec that fails to address the actual needs of an organization. These problems create a
long-term drain on both financial and other resources for a business. Hidden cost 2) Management
of the process - time: The time taken to advertise, recruit and select a candidate is a significant
hidden cost. Yet, hidden away within a company's recruitment process, this process successfully
takes up time both at junior and senior HR level, at a high cost to an organization. But more
importantly, the time of of the business manager ends up being drained on interviewing second rate
rate candidates. Management of the process covers more than just the obvious recruitment
activities. It also involves the issues around responding to unforeseen problems and also fire
fighting in dealing with staff attrition and inappropriately recruited employees. Hidden cost 3) Not
gaining the reach required to maximize success: Success in this context is the recruitment of a
candidate who combines skills, competency and an approach that matches the ethos of an
organization. Yet a limited reach in publicizing a job role can lead to the selection of a candidate
who does not provide this essential mix. This hidden problem comes right at the initial stage of the
recruitment funnel. The potential to reach potential candidates in both the active and the hidden
passive jobs market is huge - and the cost of overlooking this potential is also huge. Settling for
second best can end up having a detrimental long term cost. Turning the cost per hire obstacle into
an opportunity Maximizing a recruitment strategy whilst reducing cost per hire offers a range of
important benefits to business, aside from the obvious reduction in costs. Getting the equation right
benefits both cost and quality. It can also boost the quality of an organization in the short- and
long-term. Reducing cost per hire in a strategic way can provide positives at every level of a
business. So what are the specific advantages to turning the cost per hire obstacle into an
opportunity? Getting a pipeline of talent to support the business: Addressing the paradox right can
help create a sustainable pipeline of talent to support the business. This means building and
nurturing a long-term strategy that attracts and draws in the best available talent. This pipeline
can support the progress of the business much more effectively than less strategic approaches to
recruitment. With succession planning a key issue in many recruiters' minds, developing a
long-term pipeline addresses many important issues affecting businesses right now. Getting the
marketing mix that grows the pipeline and your brand: Addressing the hidden costs of recruitment
can reap major rewards. It's an approach that not only grows your talent pipeline, but also your
sales and marketing pipeline. Taking control of recruitment cost per hire can also mean boosting
market profile. The solution to the cost per hire problem - bring in the funnel If the lowest cost per
hire is the question, what's the answer? It's not a single solution, but a range of approaches.
Companies that adopted them had this to say: ?We thought the hidden costs were important ?
actually it doesn't matter because the fee is justified alone. In fact if we included the hidden cost,
there would be no cost to hiring people!? ?We reduced our recruitment fees by 40%, achieving a
model that support our business needs? ?We accelerated our recruitment program within days of
implementing the Response model, with such a high level of customer service the response team
changed the way we recruit forever.? So, what are the approaches that created these types of
results? Shifting focus from top to the bottom of the funnel: changing emphasis from the first stage
of recruitment to the final clarifies all the activities along the process, making them more
productive and focused. The hybrid model: the hybrid model involves a professional extension of
the team to increase potential reach and get the best of in-house/outsourced benefits. It's a model
that increases flexibility whilst maintaining quality and helps to maximize the standard and the
potential of a recruitment campaign. Outsourced marketing/advertising partner: Again, combining
flexibility with quality, this model reduces the hidden risks and costs of recruitment. An external
specialist partner helps assure the standard of the spec from the start, ensuring that it matches the
needs of the organization - and is designed to attract the right kind of candidate. A partner -
delivers on quality and quality: Working in conjunction with a partner enables a company to
reduce the time drain on its resources whilst ensuring that the highest standards are maintained.
An external specialist has a wider reach to attract a greater range of talented candidates, with a
strong relationship with in-house recruiters to support the process along the way. A commercial
structure that can't be ? missing information ? please clarify Five things every recruiter should
know about recruitment costs: 1.Cost per hire and recruitment costs are surrounded by some
popular myths. These are the myths and misconceptions that create an inaccurate picture of what
really creates the cost of recruitment. They are the commonly held beliefs that often connect cost
with one-off costs whilst overlooking the lengthier and more complex costs embedded within the
recruitment process itself. 2.Many recruiters don't count the hidden costs of recruitment It is all too
easy to overlook the time and financial drain on resources that is hidden way within a recruitment
process. In addition, while recruiters focus specifically on financial cost, they neglect the cost to an
organization's brand or the cost of the time of its senior HR staff. 3.Your recruitment process could
be costing you While many recruiters understandably address one-off and overt costs as a way to
reduce cost per hire, they miss the costs involved with the recruitment funnel. Issues with this,
especially in the early stage can significantly add to cost per hire. 4.Addressing recruitment costs
the right way can benefit a great deal more than your cost per hire Whilst reducing cost per hire is
important, addressing recruitment costs in an effective way can have a big impact on many aspects
of a business i.e Flat Fee Recruitment. A more strategic approach to tackling recruitment cost as
well as cost per hire can boost the standard of candidates, increase company profile and also reduce
the cost of staff time. 5.Mixing your recruitment model can reap financial - and other - rewards
Addressing your cost per hire alone can have limited benefits. Adopting a more ?hybrid' approach
to recruitment can have a whole range of benefits. These range from reducing the time demands on
an in-house team, to increasing the range of a recruitment campaign to maintaining a consistent
standard of quality to make the recruitment process as successful as possible.
