What Is A Mobile Handset?
 A mobile handset
 (handset) is an electronic
 device that provides
 services to users, e.g.:
    Managing address book
    Scheduling calendar
    Cellular telephony                     Example handsets:
    Accessing Internet, email   Apple iPhone, BlackBerry Storm, Palm
                                 TreoPro
 Handsets include
 smartphones and PDAs

Handset Architecture (1)

 Handsets use several hardware components:
   Microprocessor

   ROM

   RAM

   Digital signal processor

   Radio module

   Microphone and speaker

   Hardware interfaces

   LCD display
Handset Architecture (2)

 Handsets store system data in electronically-erasable
 programmable read-only memory (EEPROM)
    Service providers can reprogram phones without requiring
     physical access to memory chips
 OS is stored in ROM (nonvolatile memory)
 Most handsets also include subscriber identity
 module (SIM) cards
SIM Cards

 They include their own microprocessor and 16 KB 
  4 MB EEPROM
 They come in two sizes
 Their versatility arises from portability of
  information
    SIM card identifies subscriber to network
    Stores personal information, address books, messages, service-
     related information
Handset Operating Systems

 Currently, handsets run several OSes:
   Symbian OS
   iPhone OS (an embedded version of OS X)
   Windows Mobile
   BlackBerry OS
   Google Android Platform (based on Linux)

 With the exceptions of Symbian and Android,
  these OSes are proprietary [910]
 Telecom carriers frequently lock down handset
  firmware, OSes to prevent user modifications
Advantages of mobile technologies

Ex for 2G MOBILE HANDSET
Ex for 3G mobile handset
Some examples for 4G mobile handsets
CONCLUSION


 So by this presentation we can examine that as the
 technology is developing the compatibility and the
 features of the mobile handsets are increasing day by
 day.
