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