This thesis discusses about a motor cycle protection system using remote
control. The main components used in the system include a microcontroller AT
89C2051, a unit of modem FSK TCM3105, a transmitter IC BA1404 and a
receiver IC LAI260.
The working principle of the system concerns data transmission through
VHF radio wave, using half duplex FSK modulation, set by a microcontroller.
The experiment is conducted to observe the transmitting range from the
transmission system installed on the motor-cycle to the receiver system in the
remote control, and vice versa.
From the experiment, a well established two-way data transmission (half-duplex)
between remote control and the protection system on the motor-cycle is
achieved. The drawback lies in the fact that the data transmission range from the
remote- control to the protection system on the motor-cycle is not really far. This
is due to the low transmitting capacity of the remote control. However, this would
not be a major problem since only the far reaching communication range from the
protection system on the motor cycle to the remote control is expected
