Infrared Wi-Fi 100 Times Faster - Pros/Cons of Infrared Wifi

In recent news, researchers have found a solution to address the global Wi-Fi speed complaints. Slow Wi-Fi is a hindrance in work, data transfer, streaming, etc. Home Wi-Fi setups use up a lot of uploading and downloading data not to mention network traffic and congestion being the most frustrating experiences of all. The technology is based on harmless infrared rays that promise to be compatible with most of our electronic devices. On more surprise, it is said to be 100 times faster than the existing Wi-Fi systems at a transfer speed of 40 Gb/sec.

Technical Specifications

  • The technology uses terahertz as opposed to traditional microwaves.
  • Centralized light antennas, as they are being called are used in this system which accurately direct light rays from its inbuilt optical fibre cable. The pair of gratings radiate rays of various wavelengths at differential angles
  • Location finder of wireless devices more specific
  • Existing Wi-Fi radio signals have a frequency of 2.5-5 Gigahertzes. This system fetches lights with wavelengths of more than 1,500 nm which upgrades its frequency to an astounding 200 terahert.


  • With a huge capacity, the speed is more than 40 Gb/sec
  • With large frequencies and capacity, file and data transfer reaches a new level in terms of speed.

The Pros

  • Devices connected to this Wi-Fi system will all have different light wavelengths which results in individual spaces of capacity for them, hence eradicating network interference.
  • Congestion between cross networks will be reduced.
  • Only the device in use will have its corresponding illuminated light beam functioning for it instead of the whole area of network coverage. Hence power efficiency is at its peak.
  • Since it is a light-based network system, and light does not travel through walls, outside interference is next to nil, confirming a secure internet usage.
  • It is easy to install.

The Cons

The advantage of the system could stand as its disadvantage since it is confined within an area of particular coverage, it may be a problem. Scientists are working towards it and promise to address this challenge first thing.

In the Market

This technology is still under testing and requires many other fixes to curb its shortcomings. Also, there is a lack of funding which hinders a smooth delivery at the earliest. Researchers are expecting a market launch and easy availability in the next five years.

With each passing day, scientists are achieving the unthinkable. The world is just a touch away and with new systems, it is all the more real and a lot faster. We sure are living in an age of ultra-modernization, rapid development and discoveries.

  1. This looks like a great idea, I guess everyone is bored of there slow old Wifi. Hope scientists find a way to implement this technology soon.
