When tech experts say “the future is now,” they are not just spewing random buzzwords to get people’s attention. They pronounce the truth. Every day, the future unfolds even in the smallest of ways. And those small advancements usually end up with large breakthroughs.
One of the most notable milestones in tech is the introduction of WiFi. It has been deeply integrated in this generation’s lifestyle that most people can barely function without wireless connection. However, no matter how genius WiFi technology may be, it also has limitations. Now that more mobile devices and Internet of Things surface in the market like wild mushrooms, the extremely heavy data coming from them may be a bit too much for WiFi to handle. This is where LiFi comes in. A category of Visible Light Communication, LiFi works as LED light flickers and transmits data at an unbelievable speed. How is it better than WiFi?
LiFi is 100 times faster than WiFi
The increase of mobile and IoT devices is predicted to demand large amounts of WiFi transmissions. According to reports, more than ten billion mobile devices will utilize thirty-five quintillion or 1018 bytes of information every month by the year 2019. IoT devices are not even included in this projection. With this expected overflowing of big data, scientists have once again found a way to revolutionize data transmission with the invention of LiFi technology. This is how LiFi can address the problem of the exponential demand for high-quality and top-speed data transmission:
- Lifi can transmit data more than one hundred times faster than the good, old WiFi
- As demonstrated by scientists, LiFi can transmit data at 224 gigabits per second. Tech experts compare this to eighteen 1.5 GB movies being downloaded every second. How amazing is this result? It is definitely mind blowing.
- You only have to turn on a light, and you can enjoy the incredibly fast data transmission of LiFi.
How LiFi is powered
As it turns out, a standard ethernet cord is all one needs to power the LED lights. In order for it to start being a LiFi transmitter, LED lightbulbs only needs the additional tiny microchip required for the technology. Imagine this, more than 14 billion lightbulbs worldwide can be converted into LiFi transmitters. LiFi can be easily installed in areas where there are users who utilize both light and data services:
- Street lights
- Train stations
- Bus shelters
- Tourist information kiosks
More importantly, unlike WiFi, LiFi technology does not produce electromagnetic interference. Sensitive locations like healthcare facilities can install and enjoy LiFi transmission without compromising their safety.
How LiFi Transmission works
Despite these great advantages of LiFi over its predecessor, scientists found a couple of nuances to its transmission. First, it is discovered that in very bright daylight, the signal will be quite indistinguishable to the receivers. Second, LiFi can’t pass through walls like WiFi can. However, these seemingly inconvenient qualities can lead to better data security. It can lead companies which provide services such as IT Solutions Australia to build innovative new products for LiFi users to explore. This amazing breakthrough will also lead IT companies to strengthen their IT Security Services Australia. Furthermore, tech experts have given suggestions (e.g., smart architecture) on how to address LiFi’s bound presence.
Our appetite for advanced technology leads to more creation of mobile and IoT devices, leading to a demand of bigger consumption and faster transfer of data. In order for big data to continue growing, the next practical step is an upgrade to the ever-promising LiFi.
