IOTA Digging Deeper into LiFi Technology to Answer Internet Bottleneck

By 2020, at least 26 billion devices will be connected to the internet, according to the research firm Gartner. This means that billions of users require a stable and secure connection. IOTA Foundation is now looking into the factors to revolutionize LiFi technology to support such connection.

LiFi or Light Fidelity is an emerging internet connectivity known for its ultra high-speed data transmission and more secure environment, compared to WiFi technology. IOTA is adjusting its Distributed General Ledger technology to support LiFi and devices connected to the Internet of Things ecosystems. 

One problem the company wants to address is the significant issue called bottleneck or network congestion. LiFi seems to be the answer to the growing bandwidth problem in WiFi.

“Bandwidth is undoubtedly the last bottleneck. I can’t do anything about the speed of light. But the theoretical limits of LiFi are in terabytes per microsecond in the magnitude range,” stated John Licciardello, Fund Director at IOTA Ecosystem.

Most standard modem routers have WiFi radios that support wireless connection, but it cannot handle an unlimited number of connected devices at the same time. The typical number of connected devices per router is 10, and if they are all linked to the network all at once, expect network congestion and reduced data speed due to the lack of sufficient bandwidth.

IEEE 802.11n Wi-Fi WLAN Standard offers up to 150 Mbps data speed rate that can be boosted up to 2 Gbps with WiGig or Giga-IR. But LiFi can handle a minimum data speed rate of 1 Gbps without being boosted. Moreover, LiFi has 10 thousand times available frequency spectrum, compared to the limited frequencies of WiFi like 2.4 GHz and 5 GHz.

Right now, IOTA is making a full investigation on the maximum potential of LiFi and its light spectrum, so they can determine its capability on resolving the bandwidth shortage of WiFi.
