SECTION 7.2
MOBILITY: THE BUSINESS VALUE OF
A WIRELESS WORLD
Wireless technologies are transforming how we live, work, and play.
Handheld devices are continuing to oer additional functionality and cellular
networks are advancing rapidly in their increased speed and throughput
abilities. These enabling technologies are fueling widespread adoption and
creation of new and innovative ways to perform business.
LEARNING OUTCOMES
Learning Outcome 7.3: Describe the di*erent wireless network
categories.
There are four types of wireless networks—PAN, WLAN, WMAN, and WWAN. A
PAN provides communication over a short distance that is intended for use
with devices that are owned and operated by a single user. A WLAN is a local
area network that uses radio signals to transmit and receive data over
distances of a few hundred feet. A WMAN is a metropolitan area network that
uses radio signals to transmit and receive data, and a WWAN is a wide area
network that uses radio signals to transmit and receive data.
Learning Outcome 7.4: Explain the di*erent wireless network
business applications.
Mobile and wireless business applications and services are using satellite
technologies. These technologies are GPS, GIS, and LBS. GPS is a
satellite-based navigation system providing extremely accurate position,
time, and speed information. GIS is location information that can be shown
on a map. LBS are applications that use location information to provide a
service used by both GPS and GIS.
CLASSROOM OPENER
Great Business Decisions: Akito Morita Invents the Sony
Walkman
Akito Morita noticed that young people like listening to music wherever they
went. He decided to *nd a way for people to listen to music while they
walked, ran, danced, or jogged. From this Morita designed the Walkman. The
*rst Sony Walkman was introduced in 1980 and was an instant success.
Many of Sony’s successes are based on innovation. The company has an
instinctive ability to *nd and pursue market opportunities.
In 1949, the company developed the magnetic recording tape
In 1950, the company sold the *rst tape recorder in Japan
In 1957, the company produced a pocket-size radio
In 1960, Sony produced the *rst transistor TV in the world
CLASSROOM ACTIVITY
Nokia Wants to Track Your Location
The company is developing devices that'll track your position or any items
that you own--everywhere you go. Nokia's concept tech is basically an
expansion on the assisted-GPS tech that's increasingly embedded in devices
like cellphones. Nokia plans a hybrid system that will combine RFID tags,
Bluetooth and near-*eld communications in small keychain-sized devices
that communicate with a central hub--perhaps an advanced smartphone.

CLASSROOM DISCUSSION
Google Pays for Android Support
Google's $500 million stake in the new Clearwire could give it a major
platform for its wireless OS. The next step in Google's ambitious wireless
strategy became clear as the search giant agreed to sink $500 million into
the revitalization of struggling wireless Internet provider Clearwire. Google is
looking for support for its Android mobile operating system.
Google, along with Intel, Comcast, Time Warner Cable and Bright House
Networks, is investing $3.2 billion for the union of Sprint Nextel's and
Clearwire's wireless broadband businesses into a new wireless
communications company. The new Clearwire will work to create the *rst
nationwide mobile WiMAX network, aiming to bring speedy wireless Internet
access to the country's consumers, businesses, schools, and government
agencies.
WiMAX pipes data much faster than today's 3G wireless networks, which can
suer from high latency. This speed improvement will allow users to consume
multimedia and other bandwidth-intensive content from laptops, smart
phones and consumer electronics devices.
Clearwire earlier this year said it would begin migrating its current customers
to Gmail and Google Calendar and will use AdSense for Search to provide
Google search capabilities on future Clearwire portal applications.
Most signi*cantly, Clearwire has agreed to support Google's Android
operating system software in its future voice and data devices that it
provides to its retail customers. Android needs a major launching pad and
footprint if it is going to succeed as an alternative to Symbian, Microsoft's
Windows Mobile, the iPhone and other operating systems. Google also
agreed to work with Clearwire on an open Internet business protocol for
mobile broadband devices.
In an expanded relationship with Sprint, Google will become the default
provider of Web and local search services, which will be enabled with
location information. Sprint will preload Google Maps for mobile, Gmail and
YouTube on select mobile phones. Now Google has a signi*cant stake in a
next-generation wireless Internet company that could give Verizon and AT&T
a run for their mobile money.
The new Clearwire expects to cover 120 million to 140 million people in the
United States by the end of 2010. If those people are using Android devices,
Google will indeed become a force in the market, albeit still behind Symbian
and Windows Mobile.
CLASSROOM EXERCISE
Wireless Classrooms
Break your students into groups and ask them to develop a completely
mobile and wireless class for the future. Ask them to take into consideration
the following:
How would lectures be given?
How would questions be asked and answered?
How would assignments be given and collected?
How would group projects be performed?
How would students separate work and nonwork time?
How would exams be administered?
Would this type of class be better or worse than a traditional class?
CLASSROOM EXERCISE
Wireless Advertising
Present this information to your students…
Vindigo.com (vindigo.com) has a large database of customers willing to
accept promotional materials on their wireless devices. This is known as
permission marketing. The users download special software on their
smartphones or PDAs that allows Vindigo.com to deliver timely, accurate
information about places to go and things to do in their area. Along with
every listing, the company can deliver a customized message to the users at
a time and place where it is of most interest to them and they are most likely
to act on it.
The company targets ads by city (New York, San Francisco, Los Angeles, etc.)
and channel (Eat, Shop, or Play). Vindigo.com tracks which ads a user sees
and selects, and even allows a user to request information from an advertiser
via email. Vindigo.com determines a user's location through GPS or by asking
which neighborhoods they want to be matched with. For example, if you own
an Italian restaurant chain, you can use Vindigo.com to send a message to
anyone looking for Italian food within a few blocks of one of your locations.
You can give them directions to that restaurant and even oer them the list
of specials on the menu and discounts.
MyAvantGo.Com (avantgo.com) has over 2,500 content channels and over 7
million registered users. The content is delivered to smartphone and PDA
users. MyAvantgo oers an m-business channel and direct promotions to
deliver advertising from some of the world's top brands including American
Airlines, Chevy Trucks, the Golf Channel, CNN, the New York Times, and
Yahoo.
Hoping to become the king of location-based web domains, Go2Online
(go2online.com) helps mobile travelers *nd everything from lodging (choose
go2hotels) to Jiy Lube stations (choose go2oilchanges). Partnering with
Sprint, NexTel, Verizon, and BellSouth, Go2 makes its services available to
smartphone and PDA users. Entering "JiyLube" or hundreds of other brand
names into the Go2 system will bring up the nearest location where a
shopper can *nd that product or service.
Break your students into groups and ask them to address the following
questions:
The number of ads pushed to an individual should be limited. Why?
What security issues should vendors and users be aware of?
What ethical issues does wireless advertising cause?
Would you be willing to listen to a 10-second commercial if you got free
airtime?
