Ahmedabad-based Nav Wireless Technologies Pvt Install Li Fi Technology at The Students' Educational and Cultural Movement of Ladakh (SECMOL)
Nav Wireless Technologies and Students' Educational and Cultural Movement of Ladakh
Ahmedabad-based Nav Wireless Technologies (NavTech) Pvt Ltd has announced the installation of LiFi technology at India's highest altitude educational organisation, the Students' Educational and Cultural Movement of Ladakh (SECMOL). This is done to helping the local education fraternity, the company said in a statement here.
SECMOL was founded in 1988 by a group of Ladakhi college students who felt that the education system needed great change. For many years, SECMOL worked on reforming the government school system. At the same time, SECMOL Campus grew into an eco-village where students, staff and volunteers live, work, and learn together. It’s not a conventional school, but a place to pursue practical, environmental, social, and traditional knowledge, values, and skills. The Campus is solar powered and solar heated; students learn ancient Ladakhi songs, dance, and history alongside modern academic knowledge; and the students mainly manage, run, and maintain the campus.
Ladakh is a high desert region in the Indian Himalayas, with a culture and history drawing from Tibet, India, Kashmir, and Central Asia. SECMOL strives to equip young Ladakhis and others growing up in Ladakh, especially those from rural or disadvantaged backgrounds, with the knowledge, skills, perspective, and confidence to choose and build a sustainable future.
Li Fi means transmitting data with a light beam spectrum through open space in outdoor and indoor environments.
Li Fi systems provide ultra-fast data connections and are especially useful in urban areas where radio spectra are congested and also very useful in rural areas wherein Fiber Optic Cables or networks are not reachable.
With this Li Fi setup, it said the faculties and students would get faster and safer internet connections over the existing electric power lines for various educational purposes.
According to their website, Nav Wireless Technologies Pvt Ltd is a global leading solutions and services provider of wireless and information communications systems with its own R&D facilities, manufacturing base, and sales and service teams. The company offers a comprehensive suite of products and services including Optical Wireless Communication Systems, Wireless Electricity Transmission systems, Electronic Tattoo for Healthcare Monitoring systems, Wireless enhancement products, and subsystems and wireless transmission systems to its global customers.
NavTech is a technology company focused on Research, Design and Development in the field of Optical Wireless Communications, Electronic Materials, Renewable Energy – Nanoscale to develop high-efficiency photovoltaic devices. NavTech's R&D initiative brings advanced wireless technologies to improving lives with projects that strengthen economic and social development.
NavTech product portfolio includes Optical Wireless Communication, Smart LED Lights, Advanced Wireless Transmission Systems, Wireless Broadband and Wireless Access Equipment. NavTech's services range includes consultation, product & network design, optimisation and commissioning.
Nav Wireless Technologies is the only registered company in the LiFi sector in Asia. Expounding on the motive behind the project, CTO of Nav Wireless Technologies Hardik Soni stated that "We had approached the institute authorities for this project, and they were highly impressed with such an innovative idea to provide faster, safer, and cheaper internet. Under the leadership of SECMOL founder and president Sonam Wangchuk, the company will team up for covering the entire Ladakh and connect the unconnected areas using LiFi technology”.
"I am happy to see the set up for permanent internet connectivity using the innovative LiFi technology at our campus. This Li-Fi technology can bring revolutionary changes in the education sector,” Wangchuk said.
He said it would enable the students to stream educational videos and download resources with flawless connectivity.
"Faculties will also benefit from conducting online lectures and improving their skills. As this technology is environment-friendly, it goes with our vision to make a pollution-free and green world," he said.
What is Li Fi?
Li Fi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a Li Fi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).
VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.
How does Li Fi work?
Li Fi is a high speed, bidirectional, and fully networked wireless communication of data using light. Li-Fi constitutes of several light bulbs that form a wireless network.
When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.
Li Fi Benefits
The primary benefits of Li Fi are as follows:
• Security: Provides entirely secure access. Where there is no light there is no data.
• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.
• Localisation: Allows localisation due to the small coverage area of Li Fi access point - localisation can be used for very precise asset tracking.
• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.
