Long range wireless remote controls are designed and produced in form of hand-held devices that control other devices from miles away. Battery lives of months and ranges measured in miles are all possible when combining advanced Radio and Digital techniques. Raveon’s wireless technologies span DSP, RF, antennas, and software – making quality radios that simply communicate farther. Our unique combinations of hardware and software allow us to produce wireless remote controls, that operate in unlicensed frequency bands, which will work over many miles using simple omni-directional antennas.
The main remote control technology used in your home on the opposite is mostly infrared. The signal between a remote control handset and the device it is controlling are infrared pulses, which are invisible to the human eye. The transmitter in the remote control handset sends out a pulse of infrared light when a button is pressed on the handset. A transmitter is often a light emitting diode (LED) which is built into the pointing end of the remote control handset. The infrared light pulse represents a binary code that corresponds to a certain command, such as (power on). The receiver passes the code to a microprocessor, which decodes it and carries out the command.
In the 1980s Steve Wozniak started a company named CL 9. The purpose of this company was to create a remote control that could operate multiple electronic devices. The CORE unit (Controller Of Remote Equipment) was introduced in the fall of 1987. The advantage to this remote controller was that it could “learn” remote signals from different devices. It had the ability to perform specific or multiple functions at various times with its built-in clock. It was the first remote control that could be linked to a computer and loaded with updated software code as needed.
