The Institute of Electrical and Electronics Engineers (IEEE) has taken a groundbreaking step for the future of wireless internet standards and approved the 802.11bb standard for Light Fidelity, otherwise known as LiFi.

How does LiFi work?

Lifi technology is set to revolutionize the way we connect to the internet by utilizing light waves to transmit data. LiFi aims to alleviate the ever-increasing load placed on the radio spectrum by promising faster internet speeds and greater accessibility through near-infrared light, opening the door to a new era of connectivity. Let’s dive into Li-Fi technology, the significance of the 802.11bb standard, and the exciting prospects light fidelity brings to the world of wireless communication.

1. LiFi: Fast, Secure, Innovative

Li-Fi Internet is a wireless communication technology that employs visible light or infrared spectrum to transmit data, as opposed to the traditional radiofrequency spectrum used in WiFi. This innovation utilizes Light Emitting Diodes (LEDs) to modulate light signals at high speeds, allowing for data transmission through light waves. Lifi technology has several advantages over conventional WiFi, including increased data transfer rates, enhanced security, and reduced electromagnetic interference.

The unprecedented speed of light internet is one of the most enticing features of this wireless innovation. Unlike radiofrequency signals, which can be subject to interference and congestion, light waves travel at the speed of light. This characteristic allows LiFi to achieve data transfer rates that surpass those of traditional WiFi, as the wireless data transfer technology boasts a theoretical throughput of a minimum of 10Mb/s and a maximum of 9.6Gb/s. In practical applications, the release of the IEEE 802.11bb standard can enable the potential for seamless streaming, lightning-fast downloads, and virtually lag-free online experiences by simply using a building’s lighting system or dedicated access points.

2. Connection to Frequency and Data Haul

Discussing the LiFi speed can be simplified in a visualization exercise: the “band” can be approximated in the visible light spectrum from violet light’s 380 nanometers (nm) to red light’s 750 nm, and therefore refers to the portion of the electromagnetic spectrum that can transmit data through the wavelengths of light signals. LiFi technologies have a connection with the concept of a light band because different frequencies, including the frequency of 802.11bb when utilized for data transfer, vary in the speed by which they transfer, and determine the amount of data they are able to transfer.

3. Light Communication From the Developer’s Standpoint

The 802.11bb standard marks a true milestone for LiFi Internet, as the 802.11bb establishes the guidelines and specifications for implementing LiFi communication systems, ensuring interoperability and consistency across devices. “The IEEE 802.11bb standard is a critical step to enable interoperability between multiple vendors. It allows for the first time LiFi solutions inside the Wi-Fi ecosystem,” says Volker Jungnickel, Fraunhofer HHI’s technical editor, who played a considerable role in the technology’s development. “This is essential for the development of new and innovative applications. LiFi can replace cables with short-range optical wireless links and connect numerous sensors and actuators to the Internet. We believe that this will create a future mass market.”

The 802.11 bb standard also defines advanced modulation and multiplexing techniques that optimize the utilization of the light spectrum for data transmission. Jungnickel explains how the LiFi standard released reuses the 802.11 medium access control layer (MAC) and ODFM-based existing physical layers (PHYs) over optimal links, aiming at large-volume applications.

4. More Data, Increased Coverage, & Interoperability

Since LiFi internet aims to optimize wireless protocols, a key feature of the 802.11bb standard is spatial multiplexing or space-division multiplexing (SM, SDM, or SMX), which enhances the capacity of light fidelity systems. This technique involves the simultaneous transmission of multiple data streams using multiple light sources or antennas. By managing spatial resources, LiFi devices implementing the 802.11bb standard can achieve greater data throughput and support a larger number of connected devices within the coverage area.

The unveiling of the 802.11bb standard has also addressed concerns pertaining to signal interference, as the wireless internet standards include provisions for interference mitigation and interoperability with other wireless technologies. This ensures that LiFi systems can harmoniously operate in environments with multiple light sources or in conjunction with existing WiFi networks.

The standard’s robust security features state a clear aim to minimize the impact of external factors on LiFi performance, as well. To safeguard LiFi networks, the standard integrates encryption protocols, authentication mechanisms, and secure key exchange procedures.
