Constitution of the Radio Frequency Keyless Entry System for vehicle The radio frequency keyless entry is a system that it controls locking and unlocking doors. It can open and close sliding doors and tail gate automatically. It can notice us where the car is by panic button. The TRANSMITTER is a device that transmits the signal when the button is pressed. The transmission signal consists of preamble, header, random, key data, sync, c/s, and inter frame code. The RECEIVER is fixed inside of the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects the preamble code, it runs continuously to receive the signals completely. After receiving the signal, the receiver decides which operation will be performed. The user can select the following operations by pressing the button of the remote transmitter.

It was located more than required distance away from the shielded room wall. Radiated Emission Testing was performed according to ANSI C63.4:2003 at the open field test site. The EUT was placed in a 0.8m high table along with the peripherals. The turn table was separated from the antenna distance 3meters. Cables were placed in a position to produce maximum emissions as determined by experimentation, and operation mode was selected for maximum. The frequencies and amplitudes of maximum emission were measured at varying azimuths, antenna heights and antenna polarities. Reported are maximized emission levels. 1.9 Standards Applicable for Testing Table of tests to be carried out under FCC Part 15, Subpart B, CLASS B Test Standards Status FCC Part 15,Subpart B, Class B Applicable Deviation from Standard No Deviation 1.10 Summary of Results The data collected shows that Model HM-RX complies with Part 15.109 of FCC Technical Rules.
