Light Fidelity technology to provide high speed access to quality multimedia content in public collective transportation vehicles

A Spanish SME with great expertise in the digital TV sector is currently implementing a communication system based on Light Fidelity (LiFi) technology to allow access to high quality audiovisual content in collective transportation environments. They are looking for companies/research centers/MNEs in need of this tech/expertise to collaborate under research or technical cooperation agreement.
Spanish SME with extensive experience in the digital TV sector and more than 15 years of innovative experience within its R&D department developing breakthrough solutions in digital and communication technologies, helping the company strengthen its role in the market. Its R&D department is currently committed to implement a LiFi based communication system to access high quality audio-visual content in collective transportation environments, as well as the demonstration of the benefits of perovskites as opto-electronic components for the future of LiFi communications networks. Consumers have higher demands and expectations on their access to audiovisual content in situations of mobility, such as the frequent commutes by train or bus. Currently there are no services that can guarantee this experience due to technological limitations like range, speed, and bandwidth, as well as the interference with radiofrequency waves from other services in a radio spectrum that is increasingly saturated. There are existing products with an integrated luminaire used in smart homes, media & game streaming, and augmented reality (AR) and virtual reality (VR) that use device-to-device communication enabling downlink rates of >1Gbps and uplink rates of <600Mbps. For short range communication (mm to cm range) data rates are up to 12.5Gbps in a P2P scenario. For long range communication (cm to m range) data rates up to 1Gbps and P2P, P2MP, MP2MP scenarios. The combination of LiFi with other wireless communication technologies, complemented with IoT (Internet of Things) will boost the Smart Cities era supporting sustainable and safe mobility. To this end, the developed technology includes: • The LiFi router, consisting of a visible light emitter and infrared (IR) receiver, is connected to the internet server and luminaria LiFi. • The Luminaire LiFi, consisting of a white LED light that transmits data through pulses managed by a microcontroller. • The photodetector to receive data through IR. • The Dongle receives the data and after the amplification and processing, it is offered to the user device. • The system is completed with the ascendant link between the user’s device and the luminaire using IR technology. At one end the source device is placed, consisting usually of an LED light whose behaviour as data transmitter is managed by a microcontroller. This microcontroller modulates the light being emitted by the LED creating light pulses at very high frequencies undetectable to the human eye. This enables a dual function: light source and wireless communications link for the transmission of multimedia content. At the other end of the system, a photodetector receives the transmitted data encapsulated within the light beam and, after the amplification and processing phases, the data are offered to the user device. The system is completed with the ascendant link between the user’s device and the luminaire. These results open the door to the use of LED lamps already installed on plains, trains and buses to facilitate reading as a means of transporting data, reducing costs of installation while eliminating the problems caused by the saturation of the spectrum. Summarizing, the installation of LEDs has no need for novel infrastructures for its implementation which reduces deployment costs and the environmental impact, increasing the return on investment in terms of energy savings and low maintenance costs. The SME is looking for companies in the telecommunications sector to work under research or technical cooperation agreement. The required profile is a company, research center or MNE interested in the development of the technology. Ideal partners would be operating in the field of 5G, telecommunications or related. Expected outcome is carrying out a joint R&D research in order to develop the technology.
Type (e.g. company, R&D institution…), field of industry and Role of Partner Sought: 
The SME is looking for companies/research centers/MNEs interested in collaborating under research or technical cooperation agreement. Ideal partners would be companies from the/ in the field of 5G/ in the telecommunications sector or related. Expected outcome is the conducting a joint R&D project in order to complete the technology.
Stage of Development: 
Available for demonstration
IPR Status: 
Secret Know-how
Comments Regarding IPR Status: 
The company will carry out protection based on industrial secrecy until the product is ready for the market. At this point, it will patent the brand in all the countries in which the company operates, and will start the process to patent the system developed in the project. This patent process will be carried out in two phases. In a first phase, the patent will be processed at the Spanish level, immediately obtaining protection in the main product market. In a second phase, once agreements are reached with interested clients, the patent will be processed at the European level to obtain a higher degree of protection in the face of an internationalization. In a final phase, the patent will be processed on a global scale, in order to achieve the highest level of protection and expand the market. Regarding the results in which the property is shared with other partners, this company will be governed by the agreements established in the consortium or other agreements between the partners involved.
