  1. MITA Terminals Special course on data communications and networks: Internet Technical Architecture Seminar T-110.448 Harri Paloheimo Aura Paloheimo

  2. Content • Definition of terminal in the MITA context • A short look in the history and evolution • Terminal characteristics • MITA SW architecture for terminals • OS • Application development • Future Terminals Harri Paloheimo Aura Paloheimo

  3. Terminal concept in MITA • Mobile terminal: Any portable, transportable, or handheld terminal supporting mobility services.(ITU-T E.212) TERMINAL Application Layer Connectivity Layer Access Layer Harri Paloheimo Aura Paloheimo

  4. History Harri Paloheimo Aura Paloheimo

  5. Terminal characteristics • Limitations: • RAM • Power consumption • CPU • Weight & volume • Accesses (frequency) • Price • Impact: Sets limits to applications, services and usage Harri Paloheimo Aura Paloheimo

  6. 2G/3G Terminal complexity: Harri Paloheimo Aura Paloheimo

  7. Terminal characteristics - Access Divition by range: • Long: 2G, (E)GPRS, 3G, DVB-T • Medium: WLAN, BT • Short: IRda, serial, USB, RFID Harri Paloheimo Aura Paloheimo

  8. Terminal characteristics – User Interface • Usability:The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use. (ISO/DIS 8241-11) • For human senses: display, keyboard, audio, vibration (vs. m2m) -> evolution • Difference between a pda and a smartphone • Braille phone • UI for elderly? Harri Paloheimo Aura Paloheimo

  9. Terminal integration Harri Paloheimo Aura Paloheimo

  10. SW architecture for terminals Applications Application Programming Interfaces Application Supports APPLICATION LAYER Application Development Interfaces Application Framework and UI Support Session protocols SDK Interfaces and Libraries Network Interface and Protocols MOBILEINTERNETLAYER Application Development Interfaces I/O Drivers Operating System Core Link Layer Drivers I/O Hardware Processors and Memory Network Hardware PLATFORMLAYER Harri Paloheimo Aura Paloheimo

  11. Example: Series 60 terminals User Interface JavaPhone Application Engines Contacts, agenda, office, SyncML, data management, browsing MIDP Messaging SMS, EMS, MMS, email Java (KVM/PersonalJava) Application framework Graphical user interface framework, text and graphical utilities Personal area networking Bluetooth, infrared, USB Communications infrastructure TCP, dual IPv4 & v6, HTTP and WAP stack Multimedia Images, sounds and graphics Security Cryptography, certificate management, software installation Telephony GSM, GPRS, HSCSD, EDGE, CDMA (IS-95), cdma2000 Base User library, file server, kernel, device driver Telephone Software Harri Paloheimo Aura Paloheimo

  12. OS • Linux, Palm, MS, Symbian • Example: Symbian • Description • Characteristics • Limitations Harri Paloheimo Aura Paloheimo

  13. Application development environment Example: Series 60 • Java and C++ • Use • Limitations • Issues: new phenomena, security, operator required SW certificates, DRM Harri Paloheimo Aura Paloheimo

  14. Future terminals • Beyond 3G • Ambient networks, semantic web, combination of current access technologies (3G and WLAN) • 4G • New radio access,100 Mb/s-1Gb/s connection • Evolution of UI (HUD, voice control, projected keyboards) • Working around physical limitations • Proximity networks, fuel cells Harri Paloheimo Aura Paloheimo
