In the laser mode of communication; the signals are transmitted from the wireless transmitter to a wireless receiver without any hindrance or obstruction. Such condition is also called line of sight condition where the signals are transmitted without any obstruction.

How does a laser transmit data?
The systems use infrared light to transmit data. Though laser communications are not necessarily faster than radio waves, they are able to transmit more data in one downlink. The reason is that infrared lightwaves are much tighter than radio waves, in terms of how the data are packed.
Is laser communication possible?
Laser-based optical communication has been demonstrated between the Earth and Moon and it has the potential to bridge interplanetary distances of millions of kilometers, using optical telescopes as beam expanders.
How to transmit data with laser light?
Laser communication is used to transmit data using bit conversion operation. For laser communication two microcontrollers are used. One microcontroller is at the transmitter side and other microcontroller is at the receiver side. Laser diode is used for transmitting the signal with the help of laser.
Is laser communication faster than radio?
Lasers have frequencies at 100,000 times higher than that of radio frequencies, which means using lasers we can send and receive more bits of data per second than using RF.
