Introduction
The main scope is to detect the lost mobiles
For the detection of lost mobile SNIFFER plays a vital role
The sniffer device has to be designed precisely and size should be reduced for easy mobility for the purpose of detection
What a SNIFFER is?
The sniffer is basically a transceiver that works in the frequency which is in the special unused range that is operated by the service provided or it can designed to operate at a frequency that is of much different frequency than the one that is being used
SOFTWARE FOR THE TRACKING
The software part plays a major role in the tracking of the lost mobile phone.
The mobile phone that is lost has certain IMEI number that is embedded in the chip
The software that is to be designed in such a way that the software has the input as the IMEI number of the lost mobile phone
Working of sniffers
The working of sniffers is of two phases:
Before Sniffer increases the frequency
After Sniffer increases the frequency
Before Sniffer increases the frequency
By default Mobile devices always connects to the BTS(Base Station) and MSC(Mobile Switching Center).
Now the sniffer increases the frequency and amplitude.
