  1. Remote Control Via GSM Network Presented BY:- Suleiman Altawarah

  2. Remote Control Via GSM Network Overview: • Aim of project. • Digital Wireless Telephony. • Architecture of GSM. • Project Components. • Implementation and Experimental. • Achievements. • Conclusion.

  3. Aim of project • The main aim of the project is to implement an interfacing system to remotely control electrical appliances using the GSM network. • Using the system one can remotely switch on or off electrical machine using mobile phone.

  4. Figure below shows a functional block diagram of the system:

  5. Digital Wireless Telephony Technologies • Time Division Multiple Accesses (TDMA). • Code Division Multiple Accesses (CDMA). • Global System for Mobiles) GSM(.

  6. Digital Wireless Technologies

  7. History of the GSM • Mobile cellular systems introduced for commercial use in the 1980s. • In the beginnings of cellular systems, each country developed its own system, and so    - The equipment was limited to operate only within the boundaries of each country. - The market was also limited. To overcome these limitations, the Global System for Mobile communications (GSM) became in 1982.

  8. Specifications of GSM • Spectrum efficiency & voice quality. • International roaming. • Low mobile and base stations costs. • Compatibility with other systems (ISDN / PSTN ..etc.). • Ability to support new value added services.

  9. GSM Radio Interface Two frequency bands, of 25 Mhz for the GSM system: • The band 890-915 Mhz for the uplink • The band 935-960 Mhz for the downlink

  10. Architecture of the GSM network

  11. BTS MSC/VLR BSC Other Switching Nodes MS HLR Basic GSM Nodes AUC Radio Interface PSTN GW Of another network PABX Another MSC

  12. GSM System Blocks • Mobile Station ( MS ). • Base Station Subsystem ( BSS ). • Network Switching Subsystem ( NSS ). • Operation and Maintenance Subsystem ( OMS ).

  13. The Mobile Station (MS) + The Mobile Equipment is said to be a Mobile Station if the Subscriber Identity Module ( SIM Card ) is added to it. The SIM Card contains: A processor and a memory. that stores: - The international mobile subscriber Identity IMSI. - The Authentication and ciphering keys.

  14. Base Station Subsystem ( BSS ). • Base Transceiver Station ( BTS ) • Base Station Controller ( BSC ) • Transcoder and Rate Adaptation Unit( TRAU ).

  15. Network Switching Subsystem (NSS) • Mobile Switching Center (MSC) . • Data Base Equipments : * Home Location Register (HLR) * Visitor Location Register (VLR) * Equipment Identity Register(EIR) * Authentication Center (AUC)

  16. GSM interfaces • 1. Um interface. • 2. A interface. • 3. A bis interface. • 4. Map (Mobile Application Part).

  17. Interfaces

  18. Project Component

  19. Voice Modem Modems classified with these characteristics: • Data/fax • Data/fax/voice • Data/fax/voice/speakerphone Voice Modem:capable of supporting voice functions provided by Telephone

  20. KDTele Tools • Component allows the software to pick-up and answer incoming calls automatically

  21. Parallel port . Used to connect printers to computer. . Used in computer to controlled devices.

  22. Positive Emitter Coupled Logic (PECL). PECL: is an ultra-high speed digital logic technology and is based on a differential amplifier. - Small signal swings switching.

  23. Positive Emitter Coupled Logic (PECL).

  24. Implementation and Experimental Project block diagram.

  25. Implementation and Experimental Step #1 Programming. Interactive Voice Response System(IVRS). - IVRS: allows users to activate software through telephone keys. - KDTele.

  26. Implementation and Experimental Procedures: • Setting up the environment. • Downloading the component. • Downloading the (.DLL) file. • Adding the component to visual basic. • Recording the messages. • Writing the entire program. • Save & run.

  27. Implementation and Experimental Step #2. (PECL) Design.

  42. Achievements Through out the course work of the project I have done the following: • I have studied different related subject to the project which enhances my knowledge. • My aimed was to implement it completely, but I have tested every suction, individually either by hardware implementation, or simulation by using accusim software.

  43. Conclusion • GSM network provide mobile phone system that allows roaming of users through the world , with no distance limitation, users can control their installation from over the world via the mobile telephone. • The propose of this system is very useful and it has different applications which make human life easier. • Finally, my benefit of the project is grate and I meet the aims of the project.
