Back
when I was growing up in the 1960s, one of the big thing was the
emergence of HiFi –
high fidelity sound systems.
It was a really big deal when my Dad brought home one of these huge,
new systems. It was a big piece of furniture that occupied a
prominent position in our living room. We kids quickly hi-jacked the
new system to play our wild Elvis Presley rock & roll records.
The revolution had begun.
| High Fidelity, often shortened to HiFi, was the term used to refer to the high-quality reproduction of sound produced by the new stereo systems developed in the late 1950s and widely sold during the 1960s. This catchy term was used to distinguish the new systems from the lower quality sound produced by inferior audio recordings and equipment used back in the 1940s and early 1950s. See https://en.wikipedia.org/wiki/High_fidelity |
At the turn of the 21st century, along came something called WiFi – a wireless network using ‘radio frequency (RF)’ for interconnecting electronic devices in your home or business to each other and to the Internet. When I installed WiFi in my home around 2001, the only device connected to the wireless network was my laptop. Today, my smartphone, smart TV, and ‘Alexa’ voice assistant are all connected to it – and the number of devices is growing. Most homes in the US now have WiFi.
| WiFi is a technology for wireless local area networking to interconnect a wide variety of digital devices used in your home such as personal computers, video-game consoles, Internet routers, smartphones, computer tablets, digital cameras, smart TVs, printers, smart appliances, and other Wi-Fi compatible devices. In 1999, the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most products are sold. See https://en.wikipedia.org/wiki/Wi-Fi |
The
latest thing is LiFi. What has happened is that I have so many
devices I need connected to WiFi, that I was buying multiple network
extenders to try and cover every square inch of my house, including
the decks and my backyard. The wireless network in my home was
becoming just too complex and available ‘bandwidth’ was becoming
a problem. Thank goodness for the emergence of LiFi.
| LiFi is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi, except it uses a form of visible-light communications technology and a subset of optical wireless communications (OWC) to complement and extend your existing ‘radio frequency (RF)’ based WiFi network. LiFi can carry much more information and provides a solution to the current RF-bandwidth limitations of WiFi. See https://en.wikipedia.org/wiki/Li-Fi |
To
put it another way, think about every LED light in your house or
office as a potential LiFi communication device. Think about every
outside light, even your street lights, functioning as part of a
massive optical wireless network blanketing your town. Li-Fi has
almost no limitations on capacity. It will be able to transmit data
100 times faster than today’s WiFi networks. It boggles the mind!
Get
ready! LiFi is just about to hit the marketplace in a big way. It is
estimated that the Global LiFi market will be worth
billions by 2021. LiFi will be what makes the Internet of Things (IoT)
happen. Read "Global Light Fidelity (LiFi) Market Outlook By Size, Share, Latest Trends, And Key Players Up To 2028".
