Conclusion



Going Mobile


Business potential & growth


-

Mobile had $25B in sales


-

98.1% mobile availability


-

85% with mobile phone


-

Wi
-
Fi: 0 to 4x in 11 years


What are our options?



3G


3G
is the third generation of wireless technologies


Secured 128 bit encrypted connections


High bandwidth
-

Multimedia (Voice, Data, and Video)


Allows location based services like weather reports on
the mobile



3G (Continued)


Faster
internet access


-

up
to 384 Kbps while moving


-

up
to 3.1 Mbps while stationary


More cost for connection


Can be used only with 3G supported devices



4G

4G


The entire network is digital and packet switched


4G is designed especially for data transmission rather
than voice


Provides a mobile ultra
-
broadband Internet access
(faster)


For example, streaming video works better with 4G, with
less stuttering and a higher resolution


Video conferencing and multi
-
player online games work
better with the faster data transmission offered by
4G

4G (Continued)


Unlike Wi
-
Fi, 4G has far expanded coverage and hence,
offers more or less constant connectivity.


Users, especially business users, are more likely to use
4G, as it offers them more security than
WiFi
. This
enhances safety and privacy of data.


Technically, no company yet offers a true 4G experience
for consumers




4G (Continued)


Diverse array of applications like virtual navigation,
tele
-
medicine, etc.


AT & T has the most 4G coverage (103 cities)


Peak download speeds


-

100 Mbit/s for high mobility devices


-

~ 1
Gbit
/s for low mobility local wireless access


Scalable channel bandwidths of 5

20 MHz, optionally up
to 40 MHz




4G (Continued)


What
are the higher layer issues in 4G?

Commerce, a new Web
-
enabled retail interface, seamless, multi
screen commerce experience connects consumers 24 * 7 * 365


Mobile commerce is not just about transactions on mobile devices


Means for companies to engage with customers in richer, more
individualized ways, incorporating loyalty, incentives and location


Marketplace Fairness Act intends to force online retailers to collect
sales tax, even in states in which they don't have a presence


New regulations intend to fix m
-
commerce problems, such as
privacy concerns, but applying these to previously
-
released apps
may be difficult

Commerce (Continued)


Would you install an app from a store where you only occasionally
make purchases?


A company that optimizes its website and enriches it with content
can get by without a mobile app


Think like a consumer when building a mobile
-
friendly site


So, what are the things the customers like to see?


-

Store locations and hours


-

Clear product images


-

Easy navigation and accessibility
