Radio Frequency throughout the years

The evolution of Remote Control after the war explained.  Remote Control as a precautionary safety to engineers and promotes efficiency.

World War II has been the bloodiest war in history.  It lasted for about 6 years, from 1939 to 1945.  Soviet Union, Unites States and their allies rally against the forces of Germany, Japan and Italy.  It was on this violent occasion, the radio remote control has been tested.  Old movies depicting the war are often associated with handheld transceivers and wired remote controls in detonating bombs.  It directed naval vessels and allied boats to crash.  Perhaps, it has really proved its worth.  Scientists began to develop radio remote controllers for the industry.

The industries began the use of radio communication and with Remote Terminal Units (RTUs) communicating in the middle of 1970s. This leads to new era in communication technology.  Radio Remote Controls differ in frequency range and spectrums and may vary from application to application depending on the industry.  This remote controller promote safety precautions among users and adds mobility, thus creating higher efficiency to employees.

The most popular remote control device is the one used in Entertainment.  Home-theater application use Infrared technology to transmit or send out pulses through the light in specific codes as home theater receives it and process the information.  Radio Frequency remote controls are usually used to control garage doors, car alarms and electronic toys.  There are also some satellite TV receivers that can be controlled by RFs.  

Usually, all electronic brands use different set of command codes.  There are some controllers that are programmed to be Universal or can decode one or more manufacturer’s signals.  Remote controller wireless are also used is aircrafts.  Fuel is a combustible gas and can explode at any time.  A wireless controller is a big help on this area.  You can control the flow of the fuel when refilling and has an automatic shut-off feature for safety.
