As well as this fantastically developed technology of wireless technology, we can come up with similar but striking idea to this newly introduced one. We are actually accustomed to this sort of wireless technology as we are constantly using our wireless phones (cell phone) in our everyday lives. But there are two dimension of problem. One thing is that the wireless technology has weakness to secu
It is based on the principle of resonant magnetic induction.
Its coil generates a magnetic field at a frequency that will resonate with a second coil in a device.
Ⅰ. Rapid and widespread growth of mobile technology in the 21st century

wirelesscommunication including the satellite on when the bus started its course, where it is located in its course, and the arrival and departure time and name of each bus stop.
The terminal installed inside each bus transmits its GPS(Global Positioning System) location through satellites to BMS(Bus Management System). By using the GPS location, data on the locatio
