IrDA or Infrared Data Association was a feature in top-of-the-line devices such as mobile phones, PDAs, and laptops. Its popularity dropped when alternative wireless communications like Bluetooth and NFC took over. Since both HTC One and Samsung Galaxy S4 use IR blaster, does this mean that infrared is coming back for more?

Back in the 90s, IR was a big think, and in fact, you could do all sorts of things with IR-enabled devices such as exchanging contact details, beaming data, or controlling your TV. Unfortunately, due to advanced methods offered by Bluetooth and NFC with data sending and receiving, IR use declined in mobile devices. It is reported that in 2012, there were no current IrDA-compliant devices.
Difference between Bluetooth and Infrared Infrared technology, can travel less than 50 feet, is what most TV remotes use. In order for an infrared signal to be detected, a line of sight must be free between the transmitter and the receiver. Any large obstacle between both of them can disrupt the signal.
Bluetooth utilises radio frequency which allows it to transmits thought walls and obstacles. A Class 3 Bluetooth has a range of about 30 feet. It is ideal for syncing PDAs with PC, wireless cell phone headsets, and hands-free mode of Bluetooth-enabled automobiles.
NFC vs. Bluetooth and Infrared Near Field Communication or NFC is a new trend in smartphones. NFC was not designed to replace any other wireless technology but is preferable in some places. NFC's range is only 4 centimeters, interacts with other devices fast, and definitely quicker than Bluetooth. It reduces the security risk compared in Bluetooth and requires minimal power only. NFC has a speed of 424kbps and can be used alongside with Bluetooth to speed up a process.
Infrared Blaster on Smartphones This Infrared technology works the same on how remote controls manages TV, DVD, and similar devices. Smartphones with IR blasters can become universal remote as long as, there is a compatible receiver. Controlling other devices via IR is much faster than Bluetooth, NFC, or Clouding and may not require Internet connection at all.
