Light will sync your future devices

Smart appliances are going to be common in coming years, and we will not have to use our existing manually-operated appliances, ever. The increase in cutting-edge technologies leaves us with no choice but to accept the change of technology and adopt the same as soon as possible to make our living better and secured. This includes high-discussed technologies so far, namely, 5G/6G, Edge Computing, Cloud Computing, AI@Edge, Machine Learning, and the list goes on (as predicted by Institute of Electrical and Electronics Engineers (IEEE) Computer Society Technical Leaders from 2021)

Making your home smart with Li-Fi & Edge Computing

A change in technological grounds improves lifestyles, adds comfort to our daily life. In the upcoming era, we are looking forward to quick answers and task-finishing with the help of fast-internet service. Li-Fi & Edge Computing are going to play a very important role to make this happen.

The advantages of low-latency, communication channels of light to transmit data, and privacy, made it very simple to accept Li-Fi, and without any doubts, is flexible for the usage in a smart-home network. On the other hand, Edge Computing stands with other pros, including very-less latency and data processing of near-by appliances/users.

Consider a scenario. You are sitting on your couch and want to connect with all appliances in that room or nearby ones, Wi-Fi internet service is one of the options to make this happen.  But, what about privacy and data processing rate? It’s at this point where Li-Fi and Edge Computing come into picture. Fig. 1 depicts the flow of data processing by using these both among this transmission and connection-based scenario.

From fig. 1, we can note that the cluster of smartphones in Room 1 is connected and accessing the data shared by Room 1’s Li-Fi LED and not to other room, as light cannot be transmitted through walls and the case is similar for Room 2. This gives us the following advantages for such basic architecture:

Privacy: Data access of the room is secured with it. No other person from another room, or building, or an outsider can access the data shared by Room 1’s/2’s Li-Fi LED.

Latency: Due to high-speed of light transmission and data within is quick, hence there’s no point of high latency. Data is accessed even above the speed of Wi-Fi Network.

The Edge Node, in between, (which can be considered to be your Wi-Fi router of home or local device with processing capability or sensors) is helping to get data from both rooms to process and analyse, to give real-time stats back to smart-devices. This use of Edge Computing helps to avail the following advantage:

Local Data Processing: With the advantage of data-collection and having Edge nodes near to appliances, data processing becomes more flexible to happen on a real-time basis.

Future Devices

Current applications 

With high demand of high-bandwidth and low latency, a lot of new-budding organisations in India have stepped forward to convert villages/city infrastructure, including schools/hospitals/homes, etc, using Li-Fi Technology. Some are listed below:

Nav Wireless Technologies: Nav has implemented Li-Fi Technology in villages for fast-ethernet services for the flexibility to access data of district/village.

Babcock: Babcock is one of the pioneers using Li-Fi which can be used for any kind of building with complete implementation of a monitoring system of components of the same.

Lifi Labs Inc: Lifi Labs is a US-based organisation working on providing Li-Fi based LED Bulbs which can be controlled via the Edge Nodes of a Smart Home.

Thus, Li-Fi Technology & Edge Computing are the necessary technological pillars where the cultivation of smart appliances is being done.
