Getting Started Deploying and Supporting
Enterprise Applications on Handheld PDAs

Introduction

Handhelds are a liberating technology for the mobile worker. The
same cannot always be said for IT administrators grappling with the
swirl of issues surrounding enterprise handheld deployment - or worse,
turning the other way as handhelds creep in their back door. The
journey into handheld deployment doesn’t have to be a perilous one.
Emerging enterprise solutions are empowering IT managers to take
control of their mobile future.

Getting A Handle on Handhelds

The key to success is thorough planning. Begin with your existing
infrastructure, and think about how you want extend your information
assets out to mobile devices. And, how will you integrate them into
your existing processes and systems? Early development of a mobile
network backbone capable of supporting future growth and
proliferation of new devices is essential to the long-term success of
your mobile program.

The following is an introduction to enterprise handheld deployment
issues, from getting started to nurturing and protecting your
investment.

The Handheld Applications Guidebook, from Synchrologic

Getting a Plan in Place
Indeed, many IT shops have been reluctant to embrace and support
enterprise handheld deployments. But the time to move is now.
Handhelds have invaded the organization, with senior management
some of the early adopters. They know the benefits of having personal
information available anytime, anywhere. They want to see this
technology multiplied and adopted throughout the organization.

The wave is coming

The mandate to mobilize business data is clear. Mobile commerce is
the new benchmark. And just as companies have scrambled to do
business on the Internet, the evolution of technology continues through
handhelds and smartphones. The benefits of pervasive information
access and the ability to do business anywhere are evident in
organizations that have seized mobile commerce opportunities.

How will your company measure up against the m-commerce
benchmark? Are you supplying business data via handheld devices?
Are you supporting critical business functions with mobile
technology? Is your IT shop providing support to end-users?

There is a light at the end of the tunnel: it’s mobile commerce coming
your way. Meet it head-on with a proactive mobile deployment
strategy that includes a comprehensive, enterprise-endorsed platform
and basic device synchronization. Kick off your learning curve by
offering basic services to internal users. Those bedrock elements will
enable you to meet the rapidly evolving demands mobile commerce.

Delve into mobility with an easy-to-implement, rapid ROI mobile
solution: Consider your sales people. Most of them carry PDA devices
already. In just a few weeks, you can build a simplified version of
your existing sales force automation tool, including the infrastructure
to synchronize SFA data onto handhelds. Synchronization eliminates
time consuming and cumbersome imports and exports and duplicate
data entries.

For more information on this type of mobile solution, read the
Synchrologic whitepaper “Improving Account Manager Productivity
at Cisco Systems, Inc. - A Case Study in Enhancing a Best-of-Breed
eSales Application Through Addition of Bi-directional Data
Synchronization Capabilities for PDA Devices”. It is available on our
website.

Take a Step Back
The first step toward planning a mobile enterprise system is to take a
step back. When it comes to mobility planning, many fail to see the
forest for the trees. They consider devices ahead of applications, often
at the behest of non-IT decision makers educated by the marketing
schemes of handheld manufacturers and the media. Start by looking at
how and why the system is going to be created, not which devices will
fit into that system.

Get some perspective

• Why are you going mobile?
• Which mission critical applications will flourish?
• Which business functions stand to benefit?
• What applications will you need for your mobile initiative?
• Will they be shrink-wrapped or fully-customizable?
• Will you build custom applications?
• What kinds of devices will you need to run those applications?
• Who will use and support this technology?
• How are you going to train users? The support team?
• How will you manage the mobile applications and data?
• How will the handhelds be brought into the fold of the existing
IT environment?

The very best handheld deployment strategies are developed from the
back-end forward by answering the preceding questions. Yet in many
cases, IT is not even consulted before handheld devices are doled-out
to the masses. Start with the basics and work forward from there.
Avoid purchasing the devices before planning for how they will be
used.

Begin by capitalizing on quick-win opportunities. Build out your
mobile network capability with easy, fast-turnaround projects that
guarantee rapid returns. Use tools and technologies that will serve you
well in the future - comprehensiveness is key. Avoid getting stuck with
a hodge-podge of administrative tools and integration issues.

Budgeting for Handhelds

Don’t underestimate
The typical handheld device itself is relatively inexpensive when
compared to traditional enterprise computing assets. But don’t be
fooled. The total cost of ownership of an enterprise handheld device is
much more than the initial cost of the hardware. Even so, the
investment for handhelds is still comparatively low and the return on
investment for handheld projects is often measured in months, versus
years for traditional IT projects.

Nevertheless, it is important to budget realistically so that the project is
not waylaid by budgetary constraints. When budgeting, keep in mind
the following costs:

• Initial device purchase
• Communications and networking
• Synchronization software
• Replacement devices
• Systems management software
• Enterprise application purchase/build
• End user and support staff training

Since this is emerging technology, seek out expert industry advice and
explore how it applies to your organization and support structures. For
example, Gartner Group has built an interesting TCO model around
handheld deployments. Likewise, the vendors you call on for
assistance with various IT components should be prepared to help you
understand the costs and benefits of each element.

This is new ground for most IT shops. Don’t be afraid to leverage the
experience of technology vendors and systems integrators. Think
about working with a service provider to build out your budget and
project plan. Though handhelds are relatively new to the enterprise IT
world, there is a growing industry of systems consultants who are
experienced in the space and can help you budget, justify and plan
your project.

Take Inventory
It’s a virtual given that handhelds have penetrated your enterprise.
Most of your executives and sales team carry Palm devices. Pocket
PC’s are gaining in popularity. Your help desk takes support calls on
devices they may not even know exist. These handhelds walk out your
doors everyday, carrying your company’s valuable information assets.
The question then becomes whether or not to bring those devices into
the fold.

Survey enterprise & non-enterprise assets

Survey your employees to find out who is currently using a handheld
device. What platform are they using? What applications are they
using? What types of information assets are stored on these devices?
Then create a mobile business plan that addresses the integration of
existing devices into the system or prohibition of non-enterprise
handheld assets. Consider the security implications of allowing non-
enterprise assets into your system.

A first step is providing basic device synchronization capabilities
linked to a systems management effort. Users will be mercifully
spared from the task of duplicate data entry and rewarded with
pervasive access to their day-to-day information. You’ll be backing up
devices to the server in preparation for the inevitable. And you’ll
emerge as a hero when a user’s device fails or gets lost. At the same
time, you can start gathering device inventory information upon which
to build your mobile network plan.

The Reality of Multiple Devices
Just as in the early days of PCs, handhelds of all different flavors are
creeping in the back door. To get on top of the situation, you need
tools which accommodate a range of devices types – Palm OS,
Windows CE, Pocket PC, RIM Blackberry, EPOC phones, etc. And
you don’t want a different set of management tools for each platform
or a different set to provide different types of synchronization support.
Look for the vendor with the most comprehensive set of tools and a
clear vision for providing the most comprehensive mobile
management solution.

Why not just pick a single handheld standard and enforce it?
Unfortunately two factors come into play. Due to the relative low-cost
of the handheld device itself, users have and will continue to purchase

5


them on their own and begin storing corporate data on them. Within
any organization there will be different user classes or profiles. Each
of these users stands to benefit from added mobility in different ways,
and a variety of factors (see the next chapter) will dictate the type of
handheld device that is appropriate for any given user class.
Applications must consider individual user patterns if the device is to
achieve maximum assimilation into the enterprise.

Many of those who have purchased their own PDA also use a laptop.
The laptop has not been replaced by the handheld, rather, it serves as
an adjunct device. This pattern will continue as new devices spring up
to complement existing IT assets. You’ll want a comprehensive suite
of products to keep all these new and existing assets in sync and
adequately supported.

Speaking of existing IT assets, you’ll need to make sure the devices
you setup with enterprise applications are able to smoothly integrate
with the current environment. Nobody is going to trash their current
CRM system running against an Oracle data warehouse to
accommodate a new handheld project. Rather, you should look for an
infrastructure layer designed to link typical existing systems with the
new crop of handhelds. This layer should serve to arbitrate between
the back-end systems you employ and the variables inherent to the
different mobile devices you must support.

Device Selection
In choosing devices for mission critical applications, consider
scalability and robustness. If you purchase an underpowered
handheld simply because of the attractive hardware price, you may
sacrifice the return on your much larger infrastructure investment.
Many organizations will find that different departments and divisions
require different devices. As stated earlier, start with the high level
business objectives, move to application requirements, and then
consider the most appropriate hardware platform.

And still, there is the deployment of handhelds as companions to
laptop and notebook PCs. Handheld devices are increasingly
augmenting, not replacing, portable PCs. Certain functions such as
serious document editing require mobile PCs. The advent of handheld
devices will further differentiate between luggable versus portable
technology.

Handheld devices are often application specific devices. They may be
extending a specific application, almost becoming an appliance or
utility. The burgeoning consumer handheld market has flourished

6


largely as an extension of personal information management. Today,
organizations are looking to these same devices to extend supply chain
management, sales force automation, inventory management, facilities
management, point of care applications, law enforcement, scientific
data collection and production data collection.

Each application will influence device selection, which should
consider these fundamental issues:

• battery life
• display size
• data input
• form factor
• processing power
• storage
• communications options
• security
• application development tools

Choose a device that meets users needs

Form should follow function in device selection. Choose a device that
will fit the primary application of your user group. Then look for ways
to augment functionality and extend other applications and information
to that device. Leverage the device’s full potential and look for ways
to deliver the most value to each user. Inexpensive add-ons can add
significant value to the user’s experience and multiply your
productivity gains.

Also consider the nature of the application and the application
development tools that will be required to build the app. For Palm OS
handhelds, a variety of tools are well known in the marketplace, each
with their own pros and cons. Some are incredibly easy to use, but
may not support the full functionality you require. For Windows CE
and Pocket PC handhelds, the development tool options are more
limited, though the tools themselves tend to be more powerful.

Each additional platform you support may require additional
development effort to create a separate version of the application, and
to test the app on that platform. Even HTML forms based application
often require different versions of the forms optimized for different
display and input capabilities. The good news is that developing apps
for handhelds is almost always far simpler than doing so for PCs.

7


The Importance of Training
Early-stage handheld deployments require training to ensure success.
Handhelds are new to most IT organizations. And while users may be
accustomed to the native PIM applications that ship with most
handhelds, running a handheld enterprise application is likely a new
experience. The good news is that handhelds are generally easier to
work with, easier to build applications for and require a shorter
learning curve that traditional IT technology.

Empower users: Budget for training

Consider the training components required for your project. In the
beginning, you may need help learning about the issues and milestones
inherent to handheld deployment. Look to vendors and integrators for
insight on how to budget and plan for an enterprise handheld initiative.

Systems analysts charged with translating business objectives into a
production deployment may need training on application development
tools, supporting infrastructure technologies, typical integration points
with existing systems and the tools and techniques to bring it all
together. Your support staff will need training on the device and
application, frequently-asked user questions, and how to address issues
that arise regarding handhelds.

Finally, end users will need training on device basics, as well as how
to “manage” their devices – keeping them secure, synchronized and
integrated smoothly into their daily processes and activities.

In order to realize a quick return on your investment, which can be
surprisingly fast with handheld applications (anywhere from 1 months
to 3 months is not uncommon), industry experts advise earmarking at
least 12 to 15 percent of the total cost of ownership for training.
Enterprise-wide success rests on a holistic approach to training and
support that includes training on applications, as well as devices, and
attention to IT staff and applications analysts, as well as users.

Synchronization Overview
Synchronization is an integral and necessary component of the mobile
infrastructure. The notion of mobility in and of itself creates the need
for synchronization. For a variety of reasons, synchronization has been
sporadically embraced for laptops, perhaps because they are so often
used in environments were a landline is readily available. User
inconvenience was traded for network simplicity, often resulting in
expensive shelfware.

Forward thinking companies that did sync laptops have realized
increased performance, greater information availability and decreased
communications costs when compared with running a constant
network connection. With the accelerating adoption of super-mobile
handhelds, synchronization became a recognizable necessity, and in
turn, a hot market in and of itself.

The many faces of sync

Recently, increased focus on wireless data access has grown, including
here at Synchrologic. Yet, even with a wireless network in place, a
server connection is not always available. Until pervasive wireless
bandwidth becomes a reality in the coming years, applications and
systems absolutely must be fashioned to deal with low bandwidth and
spotty coverage. This generally requires offline applications and data
access as an option. And if critical business information is to be stored
locally at the device level, there is an inherent need to synchronize
changes and updates when a connection is possible and the adequate
bandwidth is available.

Handhelds are inherently more mobile and more accessible than any
preceding device, so the need for synchronization has become obvious.
In the handheld world, synchronization is a loosely-used term that can
mean a variety of things. In the following chapters we’ll look at some
different flavors of synchronization

9


PIM & Email Sync
Perhaps the most obvious service desired is that of maintaining
individual calendar, contact and to-do's across devices. This
information is commonly referred to as PIM data, short for Personal
Information Manager. It has immediate value to users when offered
on a portable device that is always accessible such as a Palm handheld.
Therefore, centralized management of this service is often the first
requirement considered by corporate IT.

Covering the basics

Most calendar and contact management software (e.g. Microsoft
Outlook) already supports mobile PC clients, thus this function is
probably already supported by corporate IT. It follows that
synchronization of this information would be immediately desired by
PDA and smartphone users.

Like PIM synchronization, the corporate maintenance and support of
email is another obvious user demand. Email is widely considered to
be the "most killer" of killer apps -- the one that users are most
addicted to. As users adopt more mobile devices, they generally want
IT to provide support for email on these devices.

Despite the obvious limitations of screen size, text input methods and
capacity for attachments, access to email will be an important and
necessary service to offer across all mobile computing platforms.

More tips for application selection

Look for an application will that will sync native device applications
with the existing Exchange or Notes server. It should provide
administrators with the ability to authorize certain users and
handhelds, determine which PIM/Email information will sync, and set
defaults or enforced profiles with a variety of sync options -- such as
maximum number of records, maximum record length, yes/no for text
attachments, and what data to backup to server. These will help protect
the limited storage of the device.

10


Stick with enterprise-specific products. Is it an individual, personal
handheld-to-PC sync utility that has been retroactively improvised into
an “enterprise” product? These products typically lack the necessary
administrative features and ease of administration inherent to
enterprise-developed products.

Don’t buy your PIM sync from a vendor that can’t support other
advanced sync needs, such as those outlined in the following chapters.
The inevitable result is a hodge-podge of tools requiring redundant
administrative work and continuous reconciliation and integration of
different systems.

File Synchronization
At many corporations, a vast amount of information is stored in
desktop application file formats created by word processing,
spreadsheet and presentation programs. These are typically distributed
through email or via an intranet site. Both approaches require
proactive effort by the mobile user to maintain the current version of
the document on their mobile device.

Distributing personalized file content using profiles

Instead, a mobile computing infrastructure should provide the
capability to automatically deliver personalized file content to users
depending on their profile. The current version should be maintained
automatically on their device without any effort on their part. Typical
examples of such files include sales call reports, benefits information,
product pricing, HR forms, contracts, presentations, expense reports,
company policy statements, sales literature, company positioning,
press releases, etc.

In addition, a catalog of optional documents should be made available
for users upon request. Users should have control over their
synchronization sessions, so that they can bypass optional activities to
keep their session length down when preferable, and to manage the
storage capacity on their device.

This capability should not require any change to the way the
information is maintained and stored on the corporate file server and
network. Instead, it should offer convenient graphical tools to define
the information to be published and to note which users receive
specific information on each of their mobile devices.

Delivery of key files should be guaranteed along with extensive
logging to track "who got what." File backup capability for harvesting

11


important documents from the mobile devices should also be included.

Finally, the ability to translate common file formats for viewing and
editing on non-native platforms is extremely important. A common
example is the out-of-box inability of a Palm OS-based handheld to
view MS Word or Excel documents without special user intervention.

When evaluating content synchronization and delivery technologies,
use the following features as a starting point for building your criteria:

• Basic enterprise infrastructure platform features (see below)
• Publish & subscribe model for distribution logic
• A publication wizard for configuring the logic
• Publication availability scheduling
• Device-to-server file backup
• Overwrite vs. rename configurations
• Automated scanner to detect new/updated files
• File translation/transcoding for multiple platforms
• File delivery logging
• File versioning capabilities
• Scripting wrappers for file delivery specs
• Part of a total mobile and wireless infrastructure solution

Data Synchronization Options
Data synchronization requirements for handhelds generally fall into
one of two categories. Basic data synchronization requirements are
common for relatively simple data access and collection applications
which are usually new and replacing paper-based systems. The basic
data sync server acts as a communications server, managing the
simultaneous connection of many users and passing information
between the device’s data store and a server database through a
conduit. A variety of communications modes is supported. Thus, users
may connect through desktop cradles, wireless communications, dial-
up or direct network access.

12


Basic synchronization capabilities include:

• Integration with the standard device sync mechanism such as
HotSync for Palm handhelds
• Multiple communications modes
• Field level change posting
• Full device refresh
• Refresh from an intermediate repository
• Support for standard IP protocol
• Detailed logging and alerts
• Extensive administrative control and configurations

Basic sync servers typically have a documented API. The IT
organization writes the conduit mentioned above. This conduit is
custom code written to the API of the sync server to define the data
mappings, data sharing and synchronization logic and supporting
functionality. For straightforward applications, the conduit coding
effort is easily accomplished. With more complex requirements, it is
more efficient to utilize an advanced data synchronization server than
to try to write additional functionality and management tools into your
conduit.

Typical requirements that favor the robust functionality and rich
management tools of an advanced data synchronization server include
the following:

• Support for PC or laptop clients is also required
• Business processes evolve rapidly
• Connected users share enterprise data
• Information flows between mobile users
• Data refresh/realignment is required
• A complex data model is being synchronized
• Very large transaction volumes
• Processes run against the central database
• Mission critical transactions are synchronized
• Robust administrative tools are required

Basic data collection applications, such as inventory, warehouse,
shipping, inspections, meter reading, etc., often find basic sync
solutions adequate to meet their requirements. When the above
criteria are present, purchasing an advanced data synchronization
engine will provide significant cost savings when compared with the
cost of writing, supporting and debugging a large amount of custom

13


conduit code written to define sharing rules and provide the features
mentioned below.

If your needs require an advanced data sync solution, look for the
following features to be sure you are getting everything you’ll need:

• Support for heterogeneous databases
• Store & forward architecture
• Fast synchronization sessions
• Rich administrative tools
• Change capture including triggers, ODBC, and logs
• Transaction support – serialization and rollback
• Flexible conflict management and resolution
• Support for multiple communications layers
• Full bi-directional synchronization with sharing logic
• Parameterized sharing rules
• Field level synchronization, partitioning, and data mapping
• Performance tuning utilities
• Support for complex database schema
• Non-intrusive architecture to easily integrate
• Sharing realignment and full client refresh capabilities
• An API for custom modifications
• SQL function trapping to preserve integrity
• Client side error logging

Building-in all these features via custom coding to augment the basic
data synchronization communication server can drain significant
resources. However, these capabilities are vital in managing your
mission-critical enterprise data. As a result, organizations should look
to buy, rather than build, an advanced data synchronization engine.

With basic PIM & email sync, personalized file distribution, and data
synchronization set up, you’ll be providing users with most of the
information they need to be productive, and you’ll be effortlessly
gathering and consolidating data from the field. Next we’ll address
some of the administrator’s needs.

14


Systems Management and Inventory
Synchronization of corporate data often requires that related
applications be deployed on the mobile devices. Management of
application software and systems quickly also becomes a major
requirement of a mobile infrastructure strategy.

Applications management

LAN based approaches to systems management of mobile devices are
usually unworkable. Mobile users are intermittently connected through
unreliable communications and require event driven synchronization
sessions. These factors introduce unique requirements. Support staff
are unable to physically access the machine and must somehow keep
track of overall inventory and the individual characteristics of each
device.

Thus, mobile and wireless devices demand a different type of systems
management solution, one that complements existing systems, but
meets the unique needs of the occasionally-connected user. Key
features of a mobile systems management solution should include:

• Self-upgrade support and healing
• Delivery logging
• Publish & subscribe model
• Software package wizard
• Device history tracking
• Software inventory
• Scripts able access to inventory data
• Scanner utility
• Byte-level file differencing
• Offline installation
• Versioning

Utilizing software distribution capabilities makes IT staff more
efficient at managing the mobile devices, protects user productivity,
lowers costly support incidents and prevents user downtime.

15


Managing the Mobile Network
A comprehensive mobile infrastructure solution is necessary to
achieve consistent and efficient management of your mobile network.
Reactive and fragmented support is not an option. Deployment of one
integrated mobile computing suite, complete with common
administrative and user interfaces, will provide a host of benefits.

Demand comprehensive and fully integrated

Working with a single vendor means a single contract and a single
source for support. Integrated administration reduces duplicated
efforts, provides for a simple and efficient end-user interface and
reduces training for IT staff by eliminating multiple tool sets. Cost
savings are also realized through the elimination of application
integration costs and reduced license, maintenance and support
expenses.

Look for a strong underlying platform in the solutions you consider.
Must have features include the following:

• Support for all major handheld devices
• Integrated management
• Multiple connection modes
• Remote server administration
• Administrative database
• Compression
• Scaleable architecture
• Alerts and notifications
• Microsoft Management Console plug-in
• Directory services integration
• NT domain authentication
• Manage performance thresholds and load balancing
• Server-side process execution
• Encryption
• Open APIs
• Check-point restart in communications
• Standard internet technologies
• Guaranteed delivery
• Logging and reporting
• Administrator set scheduled connections

16


Administrative console

The administrative console is the focal point for configuring and
managing your mobile and wireless infrastructure. It should offer a
robust administrative interface for maintaining the settings and rules
that drive the behavior of server based engines.

Ideally, you can have one administrative console that manages all
functions for all mobile devices you support. This console should
allow system managers to:

• Define the user base
• Define Activities (file, software, email & data distributions)
• Subscribe users to Activities
• Prioritize the order of Activity execution
• Review extensive system logs
• Review mobile device inventory
• Set alerts and notifications
• Troubleshoot and address problems

The administrative interface will allow you to interact with the mobile
network, provision new users, model changing business processes,
track down problems, monitor the aggregate device inventory for
planning, and complete all the other day-to-day tasks involved in
supporting mobile users. It’s important to have one central console,
instead of learning a variety of administrative interfaces and
duplicating tasks such as assigning a new user to a profile. Ideally,
you can manage the entire mobile network from one GUI.

Communications Options
A variety of communications options are available for connecting
handheld devices to company servers for synchronization. It is very
likely, and often advisable, for your organization to employ a mix of
the following:

• Cradle to PC sync, requires some sort of staging on PC
• Cradle through PC to network sync
• Network cradle sync
• Network dialup (wired and wireless)
• Wireless direct to server over internet sync (also wired)

17


The specific options available will vary for different handhelds, and
for different communications/networking providers. A full review of
these is beyond the scope of this paper. The important thing to keep in
mind is that the networking and connection options must serve the
user. And mobile users need options to stay connected when they are
out of range of a wireless connection, or have only a low bandwidth
dialup connection available from a hotel for instance.

So your handheld infrastructure solution, including the
synchronization and management tools will need to support a range of
communications protocols and transport mechanisms. The vendor
should be committed to providing a total solution with the flexibility
you need today -- and tomorrow.

Security Concerns
IT is ultimately responsible for the integrity, confidentiality and
availability of the enterprise system. A comprehensive infrastructure
plan will include the early integration of security solutions. The most
basic and inherent security risk posed by a mobile device is that it is
not bolted down. It walks out your doors every afternoon. It is left in
your sales person’s car. It is carried on planes, trains and automobiles
and left in hotel rooms around the world. And, it contains information
critical to your business.

Security on the new frontier

Mobile enterprise security is founded in policy and supported by
cutting edge technology. A comprehensive mobile enterprise security
solution will include:

Broad platform support. From enterprise and e-commerce servers,
to desktops and Java, all the way down to PDAs, smartphones, and
Internet appliances.

Standards Compliance. Support for all the current and de facto
standards, and complete interoperability with past, present, and
planned installations.

Network Independence. The ability to build a solution for Internet,
intranet,? ireless and even non-standard networks.
w

Mobile, Handheld, and Embedded Specialization. Toolkits
optimized to provide?full strength security that is small, fast, and
efficient even in the smallest devices.

18


Client Authentication. Provide the highest form of security on any
platform, even handhelds - a must-have feature for enterprise data
access and financial transactions.

Closing Summary

The mobility epiphany

In midst of challenges to launching an enterprise handheld
deployment, how are companies realizing success? The answer is
something of an enterprise epiphany: whenever CEO’s and CFO’s say
to themselves, “we are going to have a mobile network and we are not
afraid to support it.” The moment strikes when decision makers realize
that to become more effective, more efficient and more competitive,
they don’t have to develop big pieces of software. They discover that
mobility is less about moving people and more about moving
information. They discover that smaller pieces of software can be
rapidly deployed to handhelds which link back to their server and
effectively push critical data out into the field where users interact
with the market.

Now, the person you could have given a $4,000 laptop is doing the
same effective work with a $149 Palm OS handheld because you have
harnessed the information technology power of your existing back end
infrastructure. It’s a small price to pay when you stand to gain a full
return on your investment in as little as 2 months. And having
deployed a flexible mobile and wireless infrastructure platform, no
matter what new mobile device is coming, your network is prepared to
meet it head-on.
