Marmitek products use different types of signals. Most Marmitek products even use different types of signals at the same time.
Here you can find more information on:
IR - Infrared
RF - High frequency 5.8GHz
IR - Infrared
Infrared is a light signal that is not visible to the human eye. Infrared signals are often used in (standard) remote controls. Because light cannot travel through walls and ceilings, infrared can only be used when the equipment you want to control, is within sight. To let IR remote control commands travel through walls and ceilings, Marmitek has developed products that convert the IR signal to a high-frequency (RF) signal. This signal can travel through walls and ceilings.
The infrared signal transmits coded commands to control your devices. This coding can be done with different speeds (frequencies). The standard frequency is about 40kHz. Some brands use a frequency of 455kHz (such as Bang & Olufsen). Marmitek products can process frequencies up to 60kHz.
Technical information on infrared signals:
Range free field: max. 8m.
Range through floors and walls: none.
Infrared wavelength: 850-950nm.
Application: remote controls for equipment within sight.
RF - high frequency 5.8 GHz
A high-frequency signal can travel through walls and ceilings. Marmitek uses 5.8GHz high-frequency signals to transmit image and sound wirelessly. The frequency is so high that there is enough ‘space’ to send the entire image signal and the corresponding sound. There is no loss of quality as is the case with conversion to wireless signals.
Technical information 5.8GHz high-frequency signal:
Range free field: max. 100m
Range through floors and walls: 15 - 30m
Capacity: max. 10mW
Application: Transmission of images and sound through walls and ceilings.
