Oppo patents a smartphone featuring Li-Fi technology

Wi-fi has become a necessary part of smartphones along with numerous other Internet-connected gadgets. But, Li-Fi is an even more advanced technology that is faster and cheaper as it uses a data-transmitting technology which is quite similar to WiFi. Oppo smartphones is leading the way by patenting its first smartphone to present this technology. 


The patent, identified by LetsGoDigital, displays pictures of the sensor positioned on the Oppo smartphones. Dissimilar to Wi-Fi, an Oppo Li-Fi unit (a photodetector) is quite noticeable on the outside of the phone. This is needed as the light photons need to be transformed into currents. The pictures display the possible arrangements of the module. It is to be considered that this is just a patent for the time being. 


Additionally, Li-Fi has its own advantages and disadvantages. Li-Fi is much more quicker than Wi-Fi, multiple times faster. It is competent at transmitting at 100Mbps, and in few cases, 10Gbps. Moreover, the frequency spectrum occupancy of Wi-Fi accentuates each day as it is the sole radio-waves medium other than LTE. 


Li-Fi can be utilized to fulfill the increasing demand for wireless data as it provides a higher capacity for data transmission. It is even said to be more energy-efficient as it makes use of LED light for data transmission without any interventions. The patent was declared on July 31, 2020, and comprises 24 product images, together with a short description explaining that this smartphone is apt for Li-Fi communication.


Considering its disadvantages, one of the biggest disadvantages is its reliability on light, especially on LED bulbs. This states that a dark room with no LED light source would be disconnecting from the Internet. The next big swindle is its restricted availability. Given that light cannot penetrate walls, the confined range can be an inconvenience for a few people. For the other, this can be good in terms of security.  


On the contrary, the Li-Fi in itself isn’t completely new. It was displayed ages ago in 2012, nevertheless, it never got accepted as a mainstream technology. But, this might change if more smartphone manufacturers jump onto the bandwagon.
