  1. Overview • 1979 First mobile phone network Chicago • 1981 IBM introduces the PC. • 1981 First Portable PC (11 Kg) Osborne 1 • 1992 First smart phone – IBM Simon • July 2007 Netbook EeePC 701 • Iphone lauched 2007 and Android 2008 • IPAd Launched April 2010 (55 million sold by 2011)

  2. Classifying Devices Mobile Phone devices PC based devices Desktop Feature Phones PDA Laptop Smart Phones Netbook Tablet Devices Tablet PC Star Trek Single device??

  3. Key Characteristics • Power usage • PCs have access to mains mobile use batteries • Processor power • Due to power limitations mobile devices do not have raw processing power • Memory / Storage available • 1GB memories only recently available on smartphones • 32 GB storage limitations at present • Screen resolution • Mobile phones have smaller and lower resolution screens • Input method • Touch screens standard with soft keypads • Real Estate available • Not much space in a mobile phone!

  4. PC v Mobile Architecture Mobile Phone Apple iPhone 3GS • Reference - Making Sense of Smartphone Processors: The Mobile CPU/GPU Guide • http://www.techautos.com/2010/03/14/smartphone-processor-guide/ Standard PC

  5. Nvidia's Tegra APX2500 Chipset Several ‘cores’ on a single chip all performing specific functions. Very low power usage <1 Watt Almost exclusively ARM Chips ARM does not build chips – ARM provides customisable designs – “fabless” e.g. Qualcomm and Marvell Arm licences companies to build the CPUs, e.g. Nvidia, Samsung and Texas instruments Inside a Mobile CPU

  7. Mobile Phone Sales • It is estimated there are already nearly 6 billion mobile phone subscriptions. • 1.546 billion sales in 2011 (vs. 353 million PCs, i.e. about a 5:1 ratio) • 491 million smartphone sales • Smart phones can be expensive;- • Iphone 4s and Samsung Galaxy Nexus about £400-£500 - the same price bracket as PCs http://mobithinking.com/blog/2011-handset-and-smartphone-sales-big-picture

  8. Laptops / Netbooks • A mobile PC? Many people use lap to replace a desktop device. • Specifications are similar to Desktop (screen resolution, processor speeds, memory and storage capacities) • Tailor made mother boards for each manufacturer. • Integrated components (screen, keyboard, memory, storage) • Emphasis on low power components to increase life on battery power. • Batteries 6000mAh capacity at 11 or 14 volts giving 1-4 hours usage. • Use ‘standard’ Intel/AMD processors • Wifi/Bluetooth/USB connectivity • High end devices have separate GPUs • Netbooks – cutdown hardware / functionality to extend battery life • 7” screens, SD Hard Drives, limited Memory (1GB), Bluetooth, USB connectors

  9. Tablet Devices • Touch screen user input. • Light, typically 0.3 – 0.8 kg • Usually between 7 and 10-inch diagonal screen • May be wide screen or the older 4:3 format • Resistive (more accurate) or Capacitive (more sensitive) screens • Capacitive screens support multi-touch gestures • Usually 1.0 to 1.6 GHz CPUs

  10. Tablet Devices • Operating systems: Apple IOS, Windows 8, Android, Blackberry • Solid state devices – no moving parts, low power consumption • Usually a 5 - 10 hour battery life. • Wi-Fi/Bluetooth/USB connectivity, may have NFC, GPS • Used for web browsing, media consumption, games, reading • A big mobile phone without the telephony?

  11. Smart phone features • Processors • Still 32 bit word size • Dual Core becoming standard (among smart phones) • Almost exclusively ARM (Intel ATOM might be a contender) • Operating systems • Apple – IOS, Google – Android, Blackberry, Nokia – Windows Mobile 8 (joint venture with Microsoft) • Screens • 3.5”- 5.3” – Touch screen candy bar format • Resolution - 320 * 480 to 1920 * 1080 (HD TV res!) • LCD, AMOLED or Super AMOLED display • Capacitive or Resistive input – moving away from hard to soft keys • Memory • OS / Program Storage – 256MB – 2GB • Data Storage – 1GB – 64GB (currently ~8-16 GB standard) • Expandable Storage – usually up to 32GB

  12. Smart Phone Features (Cont) • Cameras - Back 5 – 8 Megapixel Front 0.3 – 1.3 Megapixel • Video - up to 1080p 30 frames per sec format • Audio – MP3, HE-ACC, AIF, Wav Formats at upto 320 Kbps • Connectivity • Voice and Video phone connectivity • 3G/4G Mobile Broadband ~ 7.2 Mbits per sec • Bluetooth – 3Mbits per sec • Wifi 802b/g/n – up to 300Mbits per sec • GPS functionality – Location Based services possible. • Sensors • 3 axis gyroscopes • Accelerometers • Light Sensors • Proximity Sensors • Applications – Turns device into computer? • Web Browsers

  13. Mobile Phone Apps

  14. Summary • Desktop PC sales are falling, change to… • laptops and portable devices • Netbooks have peaked and are on their way out • Mobile phone sales outstrip PC sales 5:1 (3rd world usage) • Smart phones are a ¼ of all phones sales and rising • Tablets provide much of the functionality of mobile phones in a larger form factor • Apps for mobile phones sold more than $2 billion in 2010 • The future is smart phone app shaped
