Advantages and Disadvantages of Infrared Transmission

When there is a line of sight(LOS) between the sender and the receiver, infrared technology uses focused light instead of light that is diffuse and reflected at objects like walls and furniture. One type of electromagnetic radiation that is included in the electromagnetic spectrum is infrared light. It is undetectable to the human eye and originates from heat and thermal radiation. Senders in infrared transmission might be as basic as laser diodes or light-emitting diodes (LEDs).  Massive bandwidth that is available for usage but has not yet been fully utilised is the benefit of infrared transmission. The main drawback is that the sun emits light in the infrared spectrum. This may cause many infrared transmission interference. Following are The advantages and disadvantages of infrared transmission given below.

Advantages of Infrared Transmission:

  1. The main advantage of infrared transmission is it provides secure communication due to the line of the site being from point to point to the mode of communication.
  2. Infrared transmission is a very high-speed transmission.
  3. Infrared transmission provides a wireless link between two systems.
  4. There is no requirement for a license to do it.
  5. PDAs, Computers, Notebooks and mobile phones all include an infrared data association(IeDA) interface.
  6. Electrical devices cannot interface with infrared transmission.
  7. Infrared transmission is very simple to create and very cheap.
  8. Because of the decreased power consumption, the battery in the infrared device lost charge for a longer amount of time.
  9. It responds faster than thermocouples.
  10. It has good stability over time and larger bandwidth.

Disadvantages of Infrared Transmission:

  1. The lower bandwidth of infrared transmission in comparison to other LAN technologies is one of its drawbacks.
  2. Infrared transmission cannot be used for long-range communication.
  3. The fact that infrared can be easily shielded is their primary drawback.
  4. Infrared transmission has limited transfer rates to 115 Kbit/s, yet even 4 Mbit/s is not a particularly fast data rate.
  5. Line of sight(LOS) is required for high data rates and good transmission quality.
  6. Infrared transmission cannot permeate the barrier.
  7. There is also the issue that infrared does not penetrate solid items like concrete, wood and even opaque polymeric materials.

Every technology has advantages and disadvantages of its own, which makes it perfect for specific conditions and environments. So here this article gives the advantages and disadvantages of infrared transmission to better understand this topic.
