Light is all around us. So, with such a pervasive and accessible entity, it makes sense to think about how light can be leveraged to transmit data and information. Which network type uses light pulses to transmit data, you ask?
In the current space of wireless communication, it is becoming increasingly interesting to innovate wireless technologies using existing infrastructures. Light as a vehicle for internet and wireless communication is one of the various technologies that are developing to meet the increasing demand for faster, and more reliable connectivity. It already has a dense network, with applications in cities and buildings. In this blog, we are going to talk about how Free Space Optical Communication, Optical Fiber Networks, and the emerging technology of Light Fidelity (LiFi), has emerged, highlighting their benefits and challenges, and introducing you to the iconic and innovative solutions provided by Oledcomm.
What is Free Space Optical Communication?
Free Space Optical Communication (FSO) is a technology that transmits data through light propagation in free space, such as air or outer space, as opposed to using optical fibers. Light internet in the form of FSO systems use laser beams to provide high-speed connectivity over distances ranging from a few meters to several kilometers. FSO systems are ideal for line-of-sight, direct communication where laying cables is impractical, such as between buildings or across bodies of water.
Advantages of FSO
| Greater Bandwidth | Capable of delivering gigabit-per-second speeds |
| Quick Deployment | Seamless and easy installation in comparison with traditional fiber cables |
| Security | Laser beams are difficult to intercept, enhancing data security. |
Challenges of FSO
| Weather Dependency | Atmospheric conditions like rain, fog, and dust can have an effect on overall performance |
| Line of Sight | Path between transmitter and receiver must be clear |
How light pulses can be used to transmit data
The backbone of global telecommunications is physical, and optical communication networks using light pulses to transmit data over long distances with minimal loss through the use of cables is that backbone. These networks consist of thin strands of glass or plastic fibers through which light signals are sent, carrying vast amounts of data at the speed of light.
Process of Data Transmission
STEP 1: Light Source – A laser or LED bulb generates light pulses.
STEP 2: Modulation – Data is encoded onto the light by modulating its intensity, phase, or wavelength.
STEP 3: Transmission – Light pulses carrying data glide through the optical fibers.
STEP 4: Detection – At the receiving end, a photodetector converts the light pulses back into electrical signals.
Optical fiber networks have a wide range of benefits in rapid data transmission. Besides the incredibly fast speeds of data transfer, optical fibers can transmit data over hundreds of kilometers without significant loss. It is an incredibly reliable medium for data transmission, as it is immune to electromagnetic interference.
Like any technology, however, there are underlying challenges. Optical fibers are not immune to the installation costs and labor-intensive installation process, nor can it escape its inherent fragility in comparison to traditional copper cables.
The Emergence of Light Fidelity (LiFi)
LiFi, short for Light Fidelity, is a groundbreaking wireless communication technology that uses visible light from LEDs to transmit data. Unlike traditional WiFi, which relies on radio waves, LiFi is a modular technology that modulates light intensity to send data to receiving devices equipped with photodetectors.
Light Internet: Benefits & Challenges
Benefits
| Lightning-Fast Speed | Theoretical speeds up to 224 Gbps |
| Tight Security | Limited signal range increases security as light cannot penetrate physical barriers and is contained within physical space |
| Efficiency | LED bulbs serve multiple purposes, for lightning and data transmission as well as an environmentally conscious choice |
Challenges
| Infrastructure | Implementation of this new technology requires a widespread adoption of LiFi-enabled devices and lighting systems |
| Environmental Interference | Ambient light sources can impact light internet performance |
