Differences Between Infrared and Bluetooth

Last Updated on by Daniel Lawrence

Bluetooth and infrared remote technologies are normally utilized for short-range wireless correspondence between electronic gadgets. The two innovations are compelling, but since of their altogether different capacities and impediments, they are most appropriate to altogether different applications. In many regards, Bluetooth holds an unmistakable benefit, however, infrared keeps on being famous in certain applications.

5 Differences Between Infrared and Bluetooth

Differences Between Infrared and Bluetooth

Transmission technology

Infrared wireless utilizes pulses of infrared light to send information starting with one gadget then onto the next. These pulses are imperceptible to the unaided eye, yet can be distinguished by a sensor in the accepting gadget. Bluetooth remote uses radio waves on a specific frequency (2.4 gigaHertz) for information transmission from one gadget to another. Both Bluetooth and infrared devour significantly less power than other remote advancements.


The successful reach for infrared wireless is short—for the most part, close to five meters, and frequently more like one meter. Bluetooth has the greatest scope of 10 meters, which, although twice that of infrared, is still significantly less than that of other radio-frequency remote advancements. Bluetooth appreciates a reasonable benefit over infrared in viable reach, however, the two advances are helpful just for correspondence between gadgets in general nearness to each other.

Transmission speed

Infrared wireless communicates information in a reach between 115 kilobits each second and 16 megabits each second (Mbps), contingent upon the gadget. Bluetooth sends information at a rate somewhere in the range of one and three megabits each second. Albeit the scope of rates for infrared gadgets is a lot more noteworthy than that of Bluetooth gadgets, the most widely recognized successful speed for the two advancements is around 3 Mbps.

Device location

Since it utilizes light for data transmission, infrared wireless requires an immediate view between imparting gadgets. The getting gadget should likewise be situated inside a moderately thin cone of inclusion corresponding to the sending gadget. Bluetooth, as a result of its utilization of radio waves instead of light, isn’t dependent upon these constraints; conveying gadgets can be situated anyplace inside the innovation’s viable reach.


Because of its view impediments, infrared wireless is most successfully utilized by gadgets that stay near each other and generally fixed. Perhaps the most punctual utilization of infrared was in controllers for home gadgets, and that remaining parts a famous application. Remote consoles and mice are additionally basic applications. Bluetooth at first acquired prevalence through its utilization in wireless cell headsets. It is still generally utilized in cell phones, and it is getting all the more usually utilized in PCs and fringe gadgets.

Is Bluetooth more secure than infrared?

In terms of security, Bluetooth is less secure than infrared because of the omnidirectional nature; though infrared signs must be blocked by a gadget.

What advantages does Bluetooth offer that infrared does not?

Bluetooth has a more drawn-out range than infrared. Bluetooth is additionally ready to move more information than infrared. The last benefit of Bluetooth over infrared is there is security.
