G.hn backbone and ecosystem support for Li-Fi use cases. Standardization, Spectrum and Security

ITU-T standard based G.hn technology augments spectrum usage and provides security enhancements that special use cases need. For schools, hospitals, airports, defense and government buildings and other cases where sensitive information can be a target of cyberattack, Li-Fi eliminates the risk of data interception by outsiders which are out of sight, therefore offering a vastly enhanced security platform which can be ensured using G.hn as reliable backbone.

The tremendous flexibility of G.hn technology to run over any wired medium such as powerline, coax, twisted pair and plastic optical fiber, allows Li-Fi to reach its full connectivity potential. HomeGrid Forum provides the interoperability and certification tools for enabling a complete ecosystem.

A presentation by Livia Rosu, President, HomeGrid Forum


Question 1: What drives you?
The HomeGrid Forum, an industry alliance that promotes the use of the ITU-T’s G.hn gigabit-capable networking technology standards, is touting the pairing of G.hn with Li-Fi for a full range of smart city applications driving innovation and secured communication.

Question 2: Why should the delegate attend your presentation?
For LiFi networks to reach their full potential, installations will require a high-speed backbone – which G.hn can provide for both LiFi and complementary Wi-Fi services. G.hn augments spectrum usage and provides security enhancements. LiFi and G.hn system vendors are fully prepared to embrace and support the new technology wave.

Question 3: What emerging technologies/trends do you see as having the greatest potential in the short and long run?
LiFi and Wi-Fi are both wireless technologies that complement each other and are supported by wired backbones. Wi-Fi provides greater freedom of movement, as signals can extend throughout the home and through walls, to ensure full home coverage for consumers while LiFi requires a line of sight between a lightbulb LED transceiver and a connected device, meaning that it cannot pass through walls. In other words, for sensitive environments LiFi reduces electromagnetic interference, therefore not affecting sensitive devices.

Question 4: What kind of impact do you expect them to have?
Offering a strong backbone, with the ability for bidirectional data traffic, G.hn is the key to unlocking the potential of future applications. The technology’s highly interoperable nature and scalability enables communication between all applications within the network and gives the possibility of adding more devices in the future. HomeGrid Forum’s vision comes with end-to-end IP connectivity and agile control.

Question 5: What are the barriers that might stand in the way?
Interoperability and standardization are key aspects of the wide deployment.

About Livia Rosu
Holding a Master in Business Administration and a Master in Computer Science, Rosu built her career on a solid foundation of the telecommunications industry-wide collaboration framework. She served eight years as Internet Business Development Officer and Head of External Relations for the European Telecommunications Standards Institute (ETSI). She led with her resilience, mitigation skills and advocacy of market and technological convergence to aid the establishment of partnerships with key industry alliances and organizations, such as Broadband Forum (BBF), the International Telecommunications Union (ITU), the Internet Engineering Task Force (IETF) and the IPv6 Forum. She also served as an active contributor on the Internet Corporation for Assigned Names and Numbers (ICANN), Internet Society Advisory Council (ISOC-AC) and European Commission committees in charge of open standards and protocols for the IP-connectivity and administration.

Dedicated to the development and standardization of revolutionary technologies, Rosu has spent the last decade as HomeGrid Forum Marketing Work Group Chair and Board member, being a passionate ambassador for G.hn technology. She has been instrumental in unlocking G.hn’s high connectivity potential for the wider broadband industry and has worked tirelessly to foster industry-wide collaboration for many market segments and applications.

Rosu has also led the call for service providers to unite forces to deliver end-to-end broadband connectivity to an ever-increasing portion of the world’s population and was responsible for the GiGAWire Alliance and HomeGrid Forum combining forces to create a global effort committed to compliance and interoperability of G.hn as a critical component of the Fiber to The Extension Point (FTTep) architecture. This initiative is key to accelerating the deployment of high-quality broadband services worldwide through strong collaboration among all industry partners, HGF members and technology innovators.

There is also a high level of synergy between her role as President of the HomeGrid Forum and her role at MaxLinear, where she is crucial in driving forward the company’s competitive positioning and business development strategy with system vendors, service providers and alliances for G.hn-based home connectivity, broadband access deployments and connected devices. Prior to joining MaxLinear, Rosu worked at Marvell Technology supporting G.hn system vendors that required Plug & Play capabilities. Her dedication and work with the HGF Accredited Test Houses accelerated the process of ensuring interoperability and encouraged the system developers to produce record numbers of certified home networking devices for network operator and retail deployments.
