2 The CIOs Guide to Wireless in the Enterprise Executive Overview

When not properly managed, there is a potential risk to an increase

in business mobility. More workers away rom the sae and secure

connes o their workspace increases a companys exposure to

security breaches rom lost or stolen mobile devices. Equally costly

in the long term, the improper management o mobile devices can

signicantly increase their total cost o ownership (TCO).

Companies that are moving orward with business mobility initiatives

must plan or wireless security and mobile device management rom

the start. The CIOs Guide to Wireless in the Enterprise is the rst o

several CIO Guides rom Research In Motion. It introduces many o

the notable trends and key issues associated with business mobility

and directs the reader to additional resources or consideration.

Executive SummaryOver the past decade, wireless technology has made huge strides in security, reliability and throughput. The

wireless networks o today are almost as ast and reliable as wired networks and provide much more convenience

and fexibility. As a result, there has been explosive growth in wireless networks o all types, rom Personal Area

Networks (PANs) to Wide Area Networks (WANs). This incredible growth and renewed consumer condence has

ushered in the era o Pervasive Wireless the availability o reliable, high-speed wireless connectivity nearly

wherever and whenever a user requires it. In return, pervasive wireless, together with more powerul mobile devices,has enabled a dramatic shit in employee work habits. More workers are spending more time away rom their desks

and on the road, and wherever they are and whatever the time o day, they require the tools they need to do their job.

Equally as important, over the last ew years, mobile devices have

made huge strides. A new class o mobile device, the smartphone,

eatures more powerul microprocessors, increased storage and

larger, more colorul displays. A smartphone is capable o running

many o the day-to-day applications that the consumer, pro-sumer

and business user have come to depend on. Popular applications

such as email, calendaring and messaging are standard on most

smartphones, and these devices are making it possible to mobilize

high-ROI, industry-specic applications. Smartphones gained 14%

o the handheld market in 2008 and, according to one industry study,

are expected to comprise 31% o the market by 2013.

Not just smartphones, but most o todays mobile devices go beyond

mobile voice and utilize wireless broadband networks to provide a

ull-eatured mobile internet experience. In many locations, multiple

connectivity options are available to the user, including:

Short-range communications over a Personal Area Network (PAN),

Medium-range connections over private or public Wi-Fi, or

Longer range connections using the public cellular network

to provide a Wide Area Network (WAN).

This overlapping umbrella o wireless connectivity sets orth a new

era o personal communications, the era o Pervasive Wireless the

general availability o reliable, high-speed wireless connectivity

almost wherever and whenever the user requires it. This document

will provide the reader with a high-level background on wireless

communications technology and identiy important issues and

key trends or urther reading and consideration.

IntroductionBy any measure, wireless communications can be considered a colossal success. By the end o 2008, the

International Telecommunications Union (ITU) estimated that there were over 4 billion cell phone users globally.

Incredibly, this means that almost two out o every three people on the planet have a mobile phone. Much o this

remarkable success has only recently happened, as the number o global subscribers was less than 1 billion at

the end o 2002. During the same period o accelerated subscriber growth, wireless network coverage also grew

dramatically. Wireless network operators were completing their 2G networks and were starting to build out their3G networks and planning or even urther down the road.

Many dierent types o networks share the wireless spectrum.

Each type o wireless network, such as Personal Area Networks

(PANs), Wireless LANs and MANs, has dierent capabilities,

distinctive strengths and weaknesses that make them more

suitable in dierent situations.

Personal Area Network (PAN)

A Personal Area Network (PAN) is typically low-power and

It is common when writing about or discussing mobile

telecommunications to reer to industry acronyms such as

2G, 3G or 4G. These Gs reer to the generations o mobile

telecommunications technology. The rst generation (1G) o

wireless telecommunications began in the early 1980s with

commercial deployment o Advanced Mobile Phone Service

(AMPS) cellular networks. AMPS networks used circuit-switching

technology to carry voice-only trac. In the early 1990s, mobile

operators introduced Cellular Digital Packet Data (CDPD) onto the

existing AMPS inrastructure to allow data transers up to 19.2Kbps.

The second generation (2G) o wireless telecommunications emerged

in the mid 1990s. Multiple competing digital voice standards

made 2G much more complicated than 1G. In North America, some

mobile operators adopted the Code Division Multiple Access (CDMA)

standard, while others deployed networks based on Time Division

Multiple Access (TDMA). Outside o North America, the clear winner

was Global System or Mobile (GSM) communications. Each o these

wireless technologies also released interim (2.5G) standards such as

EDGE and 1xRTT to improve network perormance and user experience.

Unortunately, 3G telecommunications are even more complicated

than 2G. The high-level goal was or the 3G standard (IMT-2000) to

create a digital, packet-switched network with increased bandwidth,

a minimum speed o 2Mbps or stationary users and 348Kbps in a

moving vehicle. Three competing 3G technologies were introduced

as evolutions rom 2G. Most GSM network operators settled on

Universal Mobile Telecommunications System (UMTS), also known

as Wideband CDMA (W-CDMA), to oer download speeds o up to

1.8Mbps. CDMA network operators deployed Code Division Multiple

Access 2000 (CDMA2000) and the more commonly known 1xEV-DO(Evolution-Data Only). EV-DO oered an advantage over UMTS

in that it was easily deployed in an overlay to the existing 2G

inrastructure. UMTS, on the other hand, would require a signicant

investment in spectrum and telecom inrastructure by the mobile

network operators. A third 3G standard, Time Division-Synchronous

Code Division Multiple Access (TD-SCDMA), has been selected as

the 3G standard or the Peoples Republic o China.

Going orward, the ITU has created the requirements or 4G wireless

networks. The requirement states that a 4G network should be an

all-IP, packet-switched network that is highly backwards compatible

with existing wireless standards. The goal or 4G is to achieve mobile

data rates o 100Mbps or mobile endpoints and speeds up to 1Gbps

or stationary terminals. The technology contenders or 4G include

Long Term Evolution (LTE) and World Interoperability or Microwave

Access (WiMAX).

Most mobile network operators have moved beyond 2G and are well

into their 3G and 3.5G deployments. Moreover, many large network

operators are rolling out their 4G inrastructure and plan to have

operational networks in early 2010. In January 2009, a market research

company estimated that there were over 290 million WCDMA (3G)

users worldwide. Another rm expects that the number o users o

mobile broadband services (3G, 3G+ technologies) will grow to over

2 billion by 2014.

Mobile Applications

Todays mobile devices are completely viable computing platorms

many boast the same processing power and physical storage as

laptop computers a ew years previously. These days, workers away

rom their desks are able to do much more than talk on the phone and

check their email. However, 1st Generation mobile applications such

as wireless email, calendaring and messaging are sae, logical and

cost-eective rst steps in an enterprise mobility strategy. They have

a tremendous ROI and can rapidly pay or an enterprise mobility

inrastructure that can then be leveraged or new mobile applications.

When considering next-generation mobile applications beyond

wireless email, businesses should identiy the challenges and

opportunities that exist, the expected returns and the associated

costs. This analysis should orm the business case to dene the

projects scope and justiy necessary investments. Regardless o

the wireless solutions businesses choose, they should be fexible,

secure and scalable beyond their users immediate needs.

to Mobile Applications.

Unifed Communicationsand Fixed Mobile Convergence

Wireless communications are becoming so pervasive and aordable

that there is a signicant global trend toward Fixed Mobile Substitution

(FMS) where consumers and businesses are substituting mobile

service or conventional landlines. According to a 2008 report, more

than 17% o US households have a cell phone and no landline, and

another 13% have a landline that they rarely use. These numbers are

consistent in the EU, where more than 18% o households are mobile

only and Finland leads the pack, where a massive 47% o households

use mobile as their only access method. One o the key enabling

technologies or FMS is Mobile Unied Communications (UC) and

Fixed Mobile Convergence (FMC).

UC is generally considered to mean the consolidation o multiple

methods o communication, including voice, email, instant

messaging, presence and collaboration into a single application,

which is controlled by a user or both business and social purposes.

For example, a UC user might have a common inbox or email,

voice and instant messages. The UC client sotware makes the user

experience similar, whether using it on a desktop or a mobile device.

According to one study, more than hal o SMBs and almost 75% o

large enterprises are evaluating, installing or running UC solutions.

UC reduces communications ragmentation and improves employee

reachability and productivity.

An important component o Mobile UC is Fixed Mobile Convergence.

Fixed Mobile Convergence (FMC) allows people to have one phone

number and voice mail that can be used on both xed (TDM or IP

desk phones) and mobile (standard mobile phones or smartphones)

devices. It should also provide seamless handover o calls between

xed and mobile networks. For example, the automatic ability to

move an active call rom desk phone to smartphone and vice versa.

or download the CIOs Guide to FMC.

Notable Trends or Enterprise MobilityAll o these types o networks PAN, WLAN, MAN and WAN are becoming aster and more reliable, resulting

in explosive growth and utilization. More mobile subscribers taking advantage o new fat-rate data plans has

resulted in a huge increase in mobile data usage. One inrastructure manuacturer estimates that by 2011, mobile

data will overtake voice trac and will continue to grow exponentially until 2013. Since mobile network operators

are deriving more and more o their average revenue per user (ARPU) rom data services, as opposed to legacy

voice, they are strongly motivated to add value to their data networks and manage costs. Mobile network operatorsare upgrading their 2G and 3G networks to increase concurrency and reduce costs, while mobile device users are

happily using the extra bandwidth or more multimedia messaging, social networking, and entirely new classes

o mobile applications or both the enterprise and the consumer.

Wireless Security

The growth in wireless network coverage and a new generation o

aster, more capable mobile devices have given mobile workers a

valuable tool to help do their work outside o the walls o the company

oce. However, there is a potential downside to this trend. More

mobile workers doing their jobs outside o the secure boundaries

o the oce increases the risk o compromising data security and/or

allowing malicious users access back to the corporate network.

There is also a higher likelihood that a mobile device that contains

sensitive corporate data will be lost or stolen. While losing data may

be only an inconvenience or embarrassment or some organizations,

signicant nancial loss and legal risks may result in many cases.

Companies that are interested in securing their mobile workers

devices and preventing unauthorized access to important company

resources need to implement an enterprise wireless security strategy.

To be eective, an enterprise wireless security strategy needs to

include means o securing the mobile device and its data, securing

the communications to and rom the mobile device to the corporate

network, and optimizing the enterprise network to support business

mobility. The most eective wireless security strategy is a proactive

one, to develop, educate, enorce and maintain an enterprise-wide

wireless security policy. For more inormation about wireless security,

visit www.blackberry.com/securityor download the CIOs Guide to

Mobile Security.

Mobile Device Management

Another important consideration or companies that are dealing

with rapidly growing ranks o mobile workers is Mobile Device

Management (MDM). MDM solutions allow IT administrators to

manage mobile devices similar to the way that they manage

desktop and laptop computers. It includes a capability to distribute

rmware upgrades, applications and conguration settings over

the air (OTA) to mobile devices no matter where the device is located.

An enterprise MDM solution ensures that mobile workers are up

to date with the latest versions o applications and data, and that

their device is secure. An eective MDM solution should include

these important eatures:

Over the Air (OTA) OTA acilitates the conguration o mobile

devices, application updates and device locks when the mobile

phone is lost or stolen.

Back-up and Restore Back-up o a mobile device is an essential

activity or dealing with hard-resets and lost or stolen devices.

It can also be used or synchronizing les and olders between

a desktop computer and a mobile device.

Asset and Confguration Management Conguration

management is designed to provide administrators the ability

to view and categorize devices by user role, device type or anyother criteria. The administrator can then selectively use the

categorization to congure application proles, mobile device

settings and registry entries.

Mobile Security Management Security management is

designed to allow the administrator to enorce power-on

passwords andVPN settings or wipe clean all corporate

data stored on a lost or stolen device.

As the numbers o dierent mobile device models grows and the

number o mobile users within a corporation reaches critical mass,

an enterprise MDM solution becomes a necessity. One analyst reportound that managed devices have signicantly lower TCO (by 53%

to 63%) than unmanaged devices. This applies to mobile devices

running native applications and those using the onboard browser

and web-based solutions. An enterprise MDM solution is designed

to improve mobile security, reduce risk and make it easier or IT

administrators to manage the growing number o mobile users.

Key Considerations or Enterprise MobilityBigger, aster networks enabling more and more mobile workers to take care o their jobs on the road and away

rom their desks seems like a great scenario. However, along with the promise o reduced operational costs and

increased productivity, there are some signicant issues to consider, such as avoiding potential regulatory issues,

legal liability and/or new and unexpected costs, which each enterprise will need to evaluate with consideration to

its particular circumstances.

This means that as many as our billion wireless subscribers around

the globe are expected to ramp up their data usage as they start to

browse the mobile web and download applications. This growth in

mobility is both an opportunity and a challenge to many enterprises.

The potential rewards or implementing business mobility are

impressive, but conversely, i not done correctly, there is the potential

or huge expenses and associated risk. Enterprises must be aware

o all o the issues surrounding business mobility. Wireless security

and device management should be planned or, implemented and

monitored to prevent data breaches and high TCO.

Research In Motion (RIM) oers a number o dierent resources

to learn more about wireless solutions in general and the

BlackBerry solution in particular. The web site www.blackberry.com

is a good place to start. The site eatures a developers orum

at www.blackberry.com/developers/orum which is used by

application developers around the world. RIM also oers BlackBerry

solution reerence documents on a variety o topics. The Technical

Knowledge Center on the site at www.blackberry.com/support

can help you nd answers to particular questions.

ConclusionThe core issue is the incredible growth in popularity o wireless technology. More and more people around the

globe are using Bluetooth appliances, Wi-Fi (private and public) and public mobile networks. Mobile devices are

becoming more capable and high-end devices like smartphones are no longer exclusive to mobile business

proessionals.
