  • 1. Shorouk-Com-5-03
  • 2. Outlines
    • What’s the problem?
    • What are the available solutions?
    • OpenBTS … What’s it ?!
    • How does it work?
    • Our expected customers?
    • Where we are?
    • Future Vision.

  • 3. What’s the problem?
    • "The poor cellular network coverage in rural areas"
    • Huge amount of investment required by the operator
    • Coverage ignorant
    • Low efficient services
    www.openBTS-egypt.org Always connected
  • 4. What are Our solutions ?
    • SATELLITE
    • Very expensive equipments
    • Special propose hand-sets
    • Expensive prices
    • No subscribers
    • OpenBTS
    • Use an existing technology ”GSM”
    • Available and cheap hand-sets
    • Less hardware required compared to existing System
    www.openBTS-egypt.org Always connected
  • 5. OpenBTS ... What is it ?!
    • The OpenBTS project is an effort to construct a software application that uses a SDR(software defined radio) to present a GSM air interface ("Um") to standard GSM handsets and uses a VoIP PBX server to connect calls.
    www.openBTS-egypt.org Always connected
  • 6. How Does it work ?
    • BTS site area = antenna , large , costly hardware and some thing that propagates radio signals
    • BTS = the core equipment that generate the air interface for the cellular network
    • OpenBTS is a software implementation of the air interface for GSM
    Always connected www.openBTS-egypt.org
  • 7.
    • It is a piece of open source SW runs a piece of open source Hardware to generate an air interface that to a cell phone looks just like any GSM cellular network
    • This combination of SW and HW is just a SDR “software defined radio”
    Always connected www.openBTS-egypt.org
  • 8. SDR “software defined radio”
    • A type of software applications that replace the radio system hardware elements [MUX's,DAC's,etc...] with equivalent pieces of code
    • It has two parts:
    • Software Framework “GNU Radio”
    • Hardware Board “USRP”
    Always connected www.openBTS-egypt.org
  • 9. USRP Always connected www.openBTS-egypt.org
  • 10. Traditional GSM network Always connected www.openBTS-egypt.org
