Abstract
faced serious challenges from large scale natural disasters. In October, 2005 earthquake
occurred in Kashmir. It was centered near the city of Muzaffarabad, and also affected Kyber
Pakhtunkhwa province. In 2010 floods due to heavy monsoon affected about 20 million people in
different areas of Pakistan. Natural disaster results into communication failure
So, licensed band communication cannot help in these types of situation. A free licensed band
communication can help us during disasters. Offline communications systems during a natural
disaster can be dangerous for affected. One of the quick and huge effects of flooding and
cataclysmic events is the sudden and wide-scale breakdown of communications infrastructure.
When local communication networks fails, the effect can be broadly felt and can wipe out access
to standard versatile or landline telecommunications, notwithstanding Internet and even satellitebased
crisis specialized devices. And one more application of this system can be, that there are
different companies and organizations that user their own private branch exchange systems. This
system can replace that old private branch exchanges.
