Multiplexing implies the capability of a channel to send out more than one signal at a time, and has been a staple property of most communication systems over the past years. While the technology has been showing a steady rate of developments, a team of scientists was dead set on giving it the jump to the next level. For the first time, the team was able to transmit data by multiplexing it across terahertz waves. These waves of very high frequency could hold the key to unlock the next generation of ultra-fast wireless networks, potentially 100 times faster than current generation devices.
Terahertz Multiplexer Transmits First Data Signal
A study recently published in Nature Communications shows a successful transmission of two real time signals of video from a terahertz multiplexer. The overall speeds achieved were 50 gigabits per second, a number 100 times faster than the fastest cellular networks of today. Daniel Mittleman, one of the corresponding authors for the study, stated that the team was able to transmit distinct streams of data through a terahertz multiplexer at extremely high speeds and more importantly, at a low rate of error. This was a historic achievement and the first time a terahertz multiplexer system was used to transmit actual data. As per the study, the use of this technology in future wireless networks is a reasonable possibility.
Terahertz Waves to Take Over Microwaves
Microwaves are what networks currently use to transmit wireless signals to devices. However, the rate at which the demand for faster and larger chunks of data across a multitude of devices is increasing, it is only a matter of time that microwaves are unable to handle the load. Terahertz waves could be just the right replacement to microwaves in conventional wireless networking. The latter operates on higher frequencies and is a foundation aspect of several experiments in the field of communications.
