Working With Mobile Devices

2. In this chapter, we will learn about mobile phones and their interaction with the cloud.
The impact that cellular phone technology has had on civilization is dramatic.
The most popular consumer device is the Nokia 1100, and the billionth cell phone that Nokia sold was an 1100 in Nigeria.
Cell phones have had nearly universal worldwide adoption.

4. Cell Phone Types
Feature phones: which are phones with added capabilities
Smartphone: that run recognized OS, Install applications, and have persistent internet connectivity.
Smartphones are replacing feature phones and for many people on the world smartphone is the only computer they will ever own.

5. Defining the Mobile Market
The top 10 countries and the percentage of their populations with cell phones in 2009 were as follows:
1. China, 797 million, 60.8 percent of the population
2. India, 635 million, 53.8 percent of the population
3. United States, 286 million, 91.0 percent of the population
4. Russia, 214 million, 47.3 percent of the population
5. Brazil, 187 million, 97.6 percent of the population
6. Indonesia, 140 million, 60.5 percent of the population
7. Japan, 107 million, 84.1 percent of the population
8. Germany, 107 million, 30.1 percent of the population
9. Pakistan, 98 million, 59.6 percent of the population
10. Italy, 89 million, 47.4 percent of the population

6. Connecting to the Cloud

7. Adopting mobile cloud application
mobile cloud computing : you are describing a model where processing is done in the cloud, data is stored in the cloud, and the mobile device serves as the presentation platform or the display.
For this model to work a phone, tablet, or laptop requires
a reliable Internet connection and
the ability to run a browser (a micro-browser, really) or another viewing application.
Currently, most of the computing applications that run on mobile devices run on the local device itself, with a few exceptions such as Google Earth, Google Maps, the major cloud mail services, and applications that provide navigation, among others

8. Features Phone and the Cloud
often it has a screen that is limited to text or very low- end graphics
categorized by having lower prices, longer battery lives, and simpler APIs
In order to cope up the advancement in technology feature phone added the capacity to run lightweight os like Java ME which gave feature phones the capability to add applications such as browsers making cloud computing more attractive on this phone.

9. Using Smartphones with the cloud
There are many different ways in which you can define a smartphone, but these are the essential characteristics:
• A smartphone has a recognizable operating system.
• A smartphone can run installable applications.
• A smartphone offers advanced calling features such as video
calls or conferencing.
• A smartphone offers messaging features.
• A smartphone comes with a touchscreen; the bigger the touchscreen
the smarter the phone.
• A smartphone offers keyboard entry, either physically or virtually.
• A smartphone has a persistent Internet connection.

10. So, definition of smartphones goes like this:
Smartphones are small computers on which you can make phone calls, send messages, and access Internet data in real time.

11. So much for smartphones, but what about the cloud?

12. So much for smartphones, but what about the cloud?
As it stands today cloud computing is based around the idea that large industrial-sized information appliances can serve up data to any and all comers.
The smartphone and eventually feature phones too, as well as tablets, laptops, and mobile internet devices, are all cloud clients.
But smartphones and the cloud, well that is dynamite because the two technologies are synergistic: you couple a client that requires a ubiquitous service with a service that is ubiquitous, and then you provide the combination with a nearly universal worldwide market penetration.

13. Consider what we haven't seen yet in smartphones that clouds can offer.
If you move smartphone execution to a virtual machine running in the cloud, smartphones are no longer constrained by their processing power, memory, or storage capacity.
The only two factors of importance are network bandwidth and display quality.
You have to think that someone will build the equivalent of a thin client/terminal service using the cloud.

14. Android
Android is the mobile device operating system originally developed by Android Inc., purchased and further developed by Google, and supported by the industry working group called the Open Handset Alliance
Android is based on Linux and GNU software.
Phones using the Android operating system were first sold by Google, branded as the Nexus One, and manufactured by HTC.

15. The Android market has more then 75000 applications listed in t
The Android market has more then applications listed in t. Notably, you will find the following Google applications:
• Google Voice, the telephone service
• Google Finance, a financial service
• Google Translate, a language searching program
• Google Shopper, a shopping search program
• Google Listen, a pod catcher and player
• Places Directory, for local search
• Google Goggles, an image recognition program
• Google Chrome to Phone Extension, which sends links and information from a Chrome browser to an Android phone
• Voice Actions for Android, a voice command and speech recognition program

16. Apple iPhone
One of the leading Internet-enabled smartphone in the market today.
The iPhone, like the iPod before it, is managed with the Apple iTunes program.
iCloud is a cloud storage and cloud from Apple inc.

17. iCloud offers the following features: iTunes in the Cloud
Calendar, Mail, and Contacts
Backup
Documents in the Cloud
Find my iPhone, iPad, iPod touch and Mac
Photo Stream
Find My Friends
iBooks
Apps
iTunes Match

18. BlackBerry
BlackBerry is known primarily for its messaging capabilities, which is probably the most advanced in the industry
there are push notification services available from a range of cloud services such as Facebook, Myspace, Ebay, and others
BlackBerry has an IM service called BlackBerry Messenger (BBM) that can send media-rich instant messages to another BlackBerry whose PIN (eight-digit ID) are known.

19. Symbian
Symbian refers to the Symbian open-source operating system and the Symbian platform that runs the operating system on feature phones and smartphones made by various OEMs.
Symbian 3 (e.g. N8) and eventually Symbian 4 will lead to the release of next-generation smartphones that will be better cloud consumer devices
Nokia bills N8 as a portable
entertainment center and provides
Web access to a variety of services
native on the device, as well as
various social networking features.

20. Windows Mobile
The platform has undergone continuous upgrade and revisions since it was first introduced in 2000 as the Pocket PC 2000.
Microsoft has worked hard to make Windows Mobile devices a natural extension for Windows developers upon which to position their products
Windows Mobile fits into the company's strategy of Software + Services by offering another platform on which Microsoft developers can stage their products and by using the Windows Azure platform through which cloud-based services can be delivered.
