INTRO TO IOS AND ANDROID

THE PLAYERS AAndroid – Open source mobile OS developed ny the Open Handset Alliance led by Google. Based on Linux 2.6 kernel IIOS – Apple’s proprietary mobile OS, iPhone, iPod Touch, iPad. Derived from OS X, very UNIX like SSymbian – acquired by Nokia 2008 WWindows Phone 8 – Microsoft – Kin(a mobile), discontinued 6 weeks after initial launch BBlackberry OS – RIM (Research in Motion), proprietary OS

THE SMARTPHONE PLATFORM WWith the iPhone being the first to the marketplace it sets the configuration of the Smartphone Platform 3G/4G connectivity WiFi connectivity Bluetooth connectivity accelerometer w/compass ambient light sensor proximity sensor GPS gyroscope

WHAT IS ANDROID AAndroid is an open source operating system, created by Google specifically for use on mobile devices (cell phones and tablets) LLinux based (2.6 kernel) CCan be programmed in C/C++ but most app development is done in Java (Java access to C Libraries via JNI (Java Native Interface)) SSupports Bluetooth, Wi-Fi, and 3G and 4G networking

WHAT IS IOS AApple’s mobile OS for phones (iPhone), tablets (iPad), handhelds (iPod), BBased on BSD Unix AApplication programming done in Objective C SSupports Bluetooth, Wi-Fi, and 3G and 4G networking

WHAT IS BLACKBERRY BlackBerry devices can record video, take photos, play music and also provide functions such as web-browsing, messaging, instant messaging, and the multi- platform BlackBerry Messenger service. The most recent BlackBerry devices are the BlackBerry Passport, BlackBerry Classic, BlackBerry Z30. The user interface varies by model; most had featured a physical QWERTY keyboard, while newer generations have relied on a multi-touch screen and virtual keyboard.

WHAT IS WINDOWS PHONE Windows Phone (WP) is a family of mobile operating systems developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone features a new user interface derived from Metro design language. Unlike Windows Mobile, it is primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010 with Windows Phone 7. Windows Phone 8.1 is the latest public release of the operating system, released to manufacturing on April 14, The Windows Phone brand was phased out in accordance to Microsoft's new branding strategy and is due to be succeeded in 2015 with the release of Windows 10 for mobile, which is designed to provide a universal experience in conjunction with the PC version of Windows 10

BLUETOOTH OOpen wireless technology Developed by Ericsson (1994) Originally supposed to replace wired RS-232 Short distance via low power, short distance radio Allows creation of personal area networks Mostly to connect wireless peripheral devices to a host computer (mice, headsets, microphones, keyboards…) Can also be used to communicate between two host computers wirelessly (replace serial cables)

WI-FI Used to brand certified products that belong to a class of wireless local area network based on IEEE Standard Currently there are 3 versions of in common use: –B–B, about 150 feet indoors, 300 ft outdoors –G–G, 54 Mbits about 150 feet indoors, 300 ft outdoors –N–N, 600 Mbits, about 1.5 miles in open air, uses MIMO (multiple input and output antennas)

3G ( 3 RD GENERATION NETWORK)  3G, short form of third generation, is the third generation of mobile telecommunications technology. This is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications-2000 (IMT- 2000) specifications by the International Telecommunication Union. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV.  Must allow simultaneous use of speech and data services and provide peak data rate of 200 kbits/sec

4G PProvides a comprehensive and secure IP based solution for IP based telephony, ultra broadband internet, gaming services and streamed multimedia. PPeak data rate of 100 Mbit for high mobility devices and 1 Gbit for low mobility devices.

COMMONLY USED PACKAGES User interface controls and widgets User interface layout Secure networking and web browsing Structured storage and relational databases (SQLite RDBMS) 2D and 3D Graphics SGL and OpenGL Audio and visual media support Access to optional hardware (GPS)
