For File Transfer, Infrared Network Technology Was Before Bluetooth And Wi-Fi.



Infrared Network : Computers equipped with an IR sensor can transfer files and other digital information using an Infrared connection. Although this IR technology was the same as that used in consumer-oriented TV remote controls, Bluetooth and Wi-Fi are far faster and more versatile.


Installation and Use


Computer infrared network connectors transmit and receive data via ports located on the back or sides of devices. Infrared adapters were installed on many laptops and hand-held devices. Microsoft Windows uses the same infrared connection method as for other local network connections.

Infrared networks were able to support two-computer connections, but they could also be created temporarily if the need arises. However, extensions to infrared technology supported more than two computers as well as semi-permanent networks.


IR Range


Infrared communications can only be used over short distances. Two infrared devices must be within a few meters of each other when networking. Infrared network signals, unlike and Bluetooth technology, cannot penetrate walls and other obstructions. They can only work within a clear line of sight. Any obstruction that blocks the direct line between two IR device also blocks IR communication.




The Infrared Data Association (IrDA), recognizes three types of infrared technology that is used in local networks:

  • IrDA_SIR: A slow-speed infrared system that supports data rates of up to 115 kbps
  • IrDA/MIR Medium-speed infrared supports data rates of up to 1.15 Mb/s
  • IrDAFIR: Supports data rates up to 4 Mbits.


Other uses for Infrared Technology


Although IR is no longer used to transfer files between computers, it still has a value in other areas. These are:


  • Night vision Infrared increases light in low-light conditions.
  • Art history: Researchers use IR technology for a peek at the layers of paint on art works to discover what’s beneath.
  • Heating – Infrared heats and conducts heat. It’s used in saunas, food-warming stations and other cooking devices such as grills.
  • Thermography: IR technology determines relative temperatures of objects.
  • Weather forecasting: The weather satellites use IR technology for cloud formations and temperature determinations.


Infrared light to Transmission – The frequency of light that isn’t visible to the eye lies between three hundred gigacycles and four hundred THz. This radiation falls within the electromagnetic spectrum. Infrared may be used as a communication medium with properties that are significantly different from radio frequencies. Infrared cannot penetrate walls, which is a necessary property. This means that the infrared is usually contained within a space. This property means that the infrared can be used in a way to reduce interference and increase the likelihood of reprocessing a similar band in multiple rooms.



Its wavelength is shorter than radio waves but longer than visible light. The infrared wavelength ranges between 850 nm and 900 nm. Infrared communication has another advantage: the huge information measure that can be used is available, but it is not being fully utilized. However, the sun’s infrared radiation is the main problem. This can cause a lot of interference to IR communication. Infrared is used often in future development of extremely high-speed wireless networks.



Standards and Applications : There are many standards for associate degrees infrared electric circuits (IRDA). The IRDA–C commonplace defines the standards for bidirectional communication in conductor devices such as keyboards, joysticks and hand-held computers. The IRDA–C commonplace works at a touch rate seventy-five Kbits/sec, so the distance can vary up to eight metres.

The IRDA D commonplace, also known as IRDA-C commonplace, provides information rates ranging from one hundred fifteen kb/s up to four Mb/s and a range of distances that can vary by one meter. The IR electric circuit was created to connect devices such as laptop computers to a pointer wirelessly.

Higher information rates can be achieved with purpose-to-purpose transmission. Devices should remain in their original locations. Broadcast allows for greater flexibility but at lower information rates. Infrared has one advantage: you don’t need an independent license for associate degree. Infrared signals have one disadvantage: they cannot penetrate walls and other objects. They are also diluted by lightweight sources.



Characteristics Point-to-Point Infrared System:

  • The frequency range is from 100 GHz to 1000 Terahertz.
  • Data rates range from 100 kbps up to 16 mbps
  • The quality and purity of the emitted light, as well as atmospheric conditions, are all factors that can affect attenuation.
  • Intense light can affect EMI.
  • It is important to align the pieces correctly.


Characteristics Broadcast infrared System:

  • The frequency range is from 100 GHz to 1000 Terahertz.
  • Bandwidth capacity is below 1 mbps
  • The quality and purity of the emitted light as well as atmospheric conditions can affect attenuation.

Infrared Applications :

  • These devices allow us to communicate wirelessly over short distances.
  • Computers can transmit files and other digital data bidirectionally using infrared transmission.
  • Due to the very high bandwidth (approximately 40TH2), it is possible to support extremely high data rates.
  • Communication between keyboard, mouse, PCs and printers.
  • It’s used in industrial, scientific, and medical applications.
