The new G.9991 Recommendation (“High-speed indoor visible light communication transceiver – System architecture, physical layer and data link layer specification”) recently published by ITU-T is a major step in the wide adoption of LiFi technology in different applications from home/enterprise networking to IoT.
This new Recommendation describes a low-latency, high speed communication system specifically designed to overcome the challenges of LiFi. With the publication of the Recommendation several ASIC implementations are now available leading to the first LiFi mature commercial products.
This presentation briefly describes the main characteristics and advantages of the new Recommendation and introduces an example of G.9991 implementation.
About Marcos Martinez
Marcos Martínez received an M.S. degree in telecommunications engineering from the Polytechnic University of Valencia (Spain). He worked for Alcatel Microelectronics, DS2 and Marvell Semiconductors in the design of high performance embedded systems in automotive, DSL, Optical access and powerline, focusing on R&D activities. In 2017, he joined MaxLinear Inc where he has been leading the standardization activities related to wireline networking and has participated in different standardization groups working on wireline networking (ITU-T Q18/15, BBF, HomeGrid Forum and Gigawire Alliance). Recently, he has been a key contributor to ITU-T G.9991 Recommendation on LiFi transceivers.
About MaxLinear Inc
MaxLinear delivers high-performance broadband and networking semiconductors based on its highly integrated radio frequency analog technology, high-performance optical networking technology and its pioneering MoCA and Direct Broadcast Satellite ODU single-wire technology.
MaxLinear was founded in 2003. The company’s original high performance, radio-frequency receiver products capture and process digital and analog broadband signals for applications including terrestrial, cable and satellite television and DOCSIS broadband. These products include both RF receivers and RF receiver systems-on-chip, or SoCs, which incorporate highly integrated radio system architecture and demodulator technology. The company’s products were based on its pioneering low power, low cost CMOS process technology.
In 2015, the company acquired Entropic, the world leader in semiconductor solutions for the connected home. Entropic pioneered multimedia over coax (MoCA) home networking technology. The company’s technology transforms how traditional broadcast and IP streaming video is seamlessly, reliably, and securely delivered, processed, and distributed into and throughout the home.
MaxLinear also offers optical networking driver and trans-impedance amplifier ICs for 100G / 400G optical data center networks. The devices use advanced technology that cut in half the number of channels needed in optical transmission modules, reducing power consumption, size and cost for 100Gbps and 400Gbps networks.
MaxLinear technology is trusted by leading telephone, cable and satellite operators, set-top box manufacturers, networking equipment providers and consumer technology providers.
